Mixed Bag & Milder

Good Evening!

After the snow has departed our part of the world, we clear out and get cold here, then turn our attention to New England, where they are expecting copious snow that could leave that area in a shambles for days.  The low that passed over us and dropped all of the snow in the central third of the state has phased up with a low that is backed into New England.  A classic Nor'easter./

All quiet here in South Central Michigan, here's a look at the forecast for Jackson and surrounding areas including Parma and Rives Junction:


Tonight, clear skies and very cold, nighttime lows down to around 5 with wind chills around zero.  Winds SE 5-10 MPH.

Tomorrow, mainly clear skies, seasonably cold, high 31, wind ESE 5-10 MPH.

Tomorrow night, increasing clouds, not as cold, low 17.  Wind SE 5-10 MPH.

Sunday, mainly cloudy, rain and perhaps a snow shower developing, high of 38.

Monday, partly to mostly cloudy with some scattered rain or snow showers, high 37.

Tuesday, continued partly cloudy, cooler, perhaps the chance of some light snow, high 32.

Wednesday, some sunshine, warming just a bit, high 35.

Thursday, a mix of clouds and sun, warmer still, high 38.

Friday, mainly cloudy skies, some scattered rain and snow showers, high 36.

There's a look at your forecast for the next six days, have a wonderful night!

Functionality Reminder

Hello Again,

I just thought that it would be a good time to remind all of you that there is more functionality on this blog that you may find useful.  Look at these pictures:

Clicking this tab brings up a pannable, zoomable weather radar.
You can select a NOAA Weather Radio here to stream and listen to.
Play with and utilize these tools and let me know what you think!  I want you to have all of the weather information you need to decide how you should get through your day.

Updated Forecast

Good Evening!

It looks like this winter weather event is finally starting to materialize here in south central Michigan.  Snow is filtering in from the southwest as well as dropping in from north of us, where it has been snowing for a good part of the day already.

Take a look at this revised snowfall forecast from the National Weather Service.  As you can see the target amounts in the bullseye have been dialed back some:

National Weather Service Snowfall Forecast through Saturday 7 PM EST
You can see here in Jackson, we'll see anywhere between 1-4" of snow depending on your location, and you will definitely see more as you head north and west.

Here's the short term forecast for the blog areas - all three larger cities are here:




I hope you have a wonderful evening, and if you must travel, please be careful!

WINTER WEATHER UPDATE


Good Evening!

Another update to our evolving weather situation, we'll have a full look at it later (after the little one goes to bed).

WINTER STORM WARNING - Clinton, Eaton, Ingham counties from now thru 12 noon tomorrow.

WINTER WEATHER ADVISORY - Calhoun, Jackson, Branch, Hillsdale, Livingston, Shiawassee, Washtenaw, Lenawee counties, from now thru 12 noon tomorrow.

Here's a look at the latest NEXRAD radar image from Grand Rapids:

Grand Rapids NEXRAD
As you can see, snow is starting to fill in south of I-96.  More details forthcoming.

WINTER WEATHER ADVISORY - UPDATED

Hello,

Just an update to our evolving winter storm situation.  The National Weather Service has changed the Winter Storm Watch to a Winter Weather Advisory for Livingston, Washtenaw, and Shiawassee counties starting at 9 PM tonight until noon tomorrow.

Lock & Load - Old Man Winter Is Lining Us Up....

Good Morning!

We have some lake-effect snow already developing from just south of Ludington and snowing all the way down into Indiana.  That snow will become more widespread as the day progresses.  Let's take a deeper dive and see what we have going on:

SUMMARY:  Cloudy skies in the area right now in advance of the low pressure system that is tracking at us from the southwest.  Add some extra moisture from southerly flow that has temperatures up around 30 right now and we have the ingredients needed for quite a mess.  If you haven't been following earlier posts, every county in the blog is under some sort of winter weather deal from the National Weather Service except  Lenawee.  Let's run them down for you again here really quick.


WINTER STORM WARNING - Clinton, Eaton, Ingham counties from 12 noon today through 12 noon tomorrow.

WINTER STORM WATCH - Livingston, Shiawassee, Washtenaw, from 3 PM today through 10 AM tomorrow morning.

WINTER WEATHER ADVISORY - Calhoun, Jackson, Branch, Hillsdale, from 12 noon today thru 12 noon tomorrow.

Taking a look at the Grand Rapids NEXRAD radar, you see the snow already cranking up out over Lake Michigan and well off to our north, where the heart of the storm is forecast to track.

Grand Rapids NEXRAD Radar 
Snow amounts up to a foot are possible up around Ithaca, Mt. Pleasant, and Big Rapids, among other places.  We keep temperatures in the freezing range today and into tomorrow, so that's perfect for plenty of moist wet snow.  This snowfall will be more of a pain to get cleaned up than the powdery stuff we have had for the most part up until now.  Please be careful if you are out having to shovel it!

Looking ahead, as this storm departs to the east, we drop temperatures dramaticlaly in time for the weekend, with nighttime lows below 10 degrees.  On Sunday we see a warm up into the upper 30's and some places may see a 40 or two in the area, especially on Monday.  That will cause messy driving and such with snow melt that re-freezes into ice, and it could even cause some flooding issues as the snow melt isn't easily absorbed into the frozen ground.

SNOW:  Plenty of it on the way.  Have a look at this map from the National Weather Service that shows what they think the snowfall amounts will be over the next 12-24 hours:

National Weather Service Snowfall Forecast ending 7 PM Friday Evening
As you can see, this storm is expected to track right across the central third of the state as you go from north to south, with 12-15" possible in that part of the world!  They can keep it too!  After that we see clearing skies for Friday and into Saturday, and that's what will allow the mercury to nosedive into the single digits overnight Friday and into the start of the weekend.  Sunday evening into Monday, we see another disturbance moving in that may bring us any mode of precipitation.  Right now, I see a better than even chance at a wintry mix of precipitation, or even rain, starting Sunday evening and carrying over into at least part of the day on Monday.

Here's a look at the forecast for Jackson and vicinity:


Today, cloudy, a mixed bag of precipitation develops after lunch, becoming snow later, high 32, winds SE 5-10 MPH.  Perhaps an inch of snow accumulation and a bit of ice before we change over.  Use caution heading home this evening from work and school.

Tonight, cloudy, snowy by 9 PM, accumulations should be three to five inches, depending on location.  Not as cold, low near 23, winds N 10-15 MPH.

Friday, snow diminishing early afternoon, an additional inch of snow by mid-afternoon is possible, high 28, north winds turning ESE 5-10 MPH.

Friday night, clearing skies and very cold, nighttime lows down to around 10 with wind chills around zero.  Winds SE 5-10 MPH.

Saturday, clear skies seasonably cold, high 31, wind SSE 5-10 MPH.

Saturday night, clear and cold, low 16.

Sunday, increasing clouds, a wintry mix or even some rain develops, high of 36.

Monday, partly to mostly cloudy with some scattered snow showers, high 40.

Tuesday, continued partly cloudy, cooler, perhaps the chance of some light snow, high 35.

Wednesday, some sunshine, colder still, high 33.

There's a look at your forecast for the next six days, I do you have a great Thursday!  Blessings.

WINTER WEATHER ALERTS - UPDATE #2


Good Morning!

Short Term Forecast - Ann Arbor

Wolverine Country, keep your eyes open for this one...


Short-Term Forecast - Lansing

Capital City - Get ready for some snow!


Short-Term Forecast - Jackson

Here's a look at the short-range forecast for Jackson:


Big Changes, Big Snow Northwest...

Good Evening!

We had bright sunshine throughout South Central Michigan this hump day.  We'll be seeing some significant changes and some more snow as we barrel toward the weekend though - let's dive in and have a look at it all...

SUMMARY:  High temperatures in the area made it into the 30's today.  We keep our clear skies around for awhile longer, then we change it up as our next system heads this direction.  This guy will pack a punch, I'll get into detail below.

Looking ahead, we see temperatures actually struggle above freezing briefly, in front of a storm system tracking in from the west-southwest that will bring us plenty of snow for Thursday and Friday, then we fall back into the freezer until Sunday (more on the precipitation below).  Next week, forecast data is suggesting readings a good 10 degrees milder than we are right now in the early part of the week, so the good news is what we get from this storm, we will melt off at least somewhat in the next week if everything verifies as advertised.

SNOWSTORM:  The National Weather Service has already sounded the alert for a storm that will impact the blog tomorrow and Friday, especially in the north zone.  Winter Storm Warning for Clinton, Eaton, and Ingham counties; Winter Storm Watch for Shiawassee, Livingston, and Washtenaw counties; Winter Weather Advisory for Calhoun and Jackson counties.  Details can be found in the prior blog post.  The northwest corner of the blog could see as much as a foot of new snow starting tomorrow and continuing through Friday morning.  Along the I-94 corridor, somewhat lower accumulations, but a wintry mix is possible that will make travel an adventure.  Take a look at this forecast map from the National Weather Service:

National Weather Service Snowfall Forecast through Friday night 7 PM EST
A slight ridge with southerly flow adds moist air to the mix as a low arrives at almost the same time, setting the stage for all modes of precipitation.  As the low moves by, winds spin around to the NNW, and the snow falls.  We'll keep a close eye on the track of this thing, if the track comes further south, oh boy...

POST-STORM:  After the snow is done, things settle down and we are quiet for a bit.  Cold temperatures Saturday due to Canadian high pressure filtering in, then we start warming up sharply on Sunday.  If the GFS has it right, we jump into the 40's on Sunday, and increase the chances of precipitation for the new work week, and this looks like rain or perhaps a wintry mix based on the forecast modeling.  For my money, I think the computer is a bit ambitious, and I would say something more like 39 for Sunday.  I'll need to see another run or two of model data to refine that estimate.

All quiet in the area right now, here's the forecast for Jackson and surrounding areas including Spring Arbor and Parma:

Tonight, clear to start then clouds increase as the night progresses, nighttime lows near 18 with winds S 3-6 MPH.

Tomorrow, increasing clouds, a wintry mix develops after lunch then changes to snow later, high 32, winds SSW 4-8 MPH.  Maybe an inch of accumulation and/or some ice before the changeover.

Thursday night, cloudy with some lingering traces of wintry mix precipitation, it should be all snow by 8 PM, accumulations should be three to five inches, depending on location.  Not as cold with a low down to about 23, winds SSW 4-8 MPH.

Friday, snow diminishing early afternoon, an additional inch of snow by mid-afternoon is possible, high 27, wind SSE and working  to N 6-12 MPH.

Friday night, clearing skies and very cold, nighttime lows down to around 10 with wind chills at or below zero.  Winds N 5-10 MPH.

Saturday, clear skies and cold, high 25.

Sunday, increasing clouds, a wintry mix or rain develops midday, much warmer, with a high of 39.

Monday, partly to mostly cloudy with some scattered snow showers, high 38.

Tuesday, continued partly cloudy, cooler, perhaps the chance of some light snow, high 35.

Wednesday, some sunshine, colder still, high 33.

There's a look at your six day forecast, stay tuned to the blog, Twiiter, Facebook, and Google + for updates on the storm situation.  Have a blessed night!

Quick Look - Updated

A sharp-eyed reader pointed out a goof in my 36 hour forecast - I did cover it in the detailed one, but we have a Clipper set to snow on us tomorrow afternoon, but I only put in flurries initially.  That's been corrected.  Thanks Tyler!

Also, The National Weather is still allowing the Winter Weather Advisory to expire at 1 PM, they expect only another inch of accumulation or so as the snow winds down.


Steady Snow...Slowly Warming...

Good Morning!

Big, thick snowflakes falling in the area at this hour.  A Winter Weather Advisory continues for the south zone of the blog through 1 PM.  I expect 1-2" of additional accumulation between now and when all of this starts to taper off later this morning and into the afternoon hours.  Let's take a dive into it and see what we have going on...

SUMMARY:  A bit of an upper disturbance is evident at about 5000 feet off the ground according to the charts I have looked at this morning, and that, combined with the moisture we have available, and winds blowing off the lake is all mixing to to make well, a mess.  We would have had the lake-effect snow anyway, but that upper disturbance is helping it and that's why we have more copious snowfall.  I'm thinking that as the disturbance slides by to the south, we gradually lose some of the snow, as it won't have a helping hand to stay as organized as it is now.  Fairly organized lake-effect should still be in play for places west of I-69 though with northwest winds.  Have a look at the Grand Rapids NEXRAD radar...

Grand Rapids NEXRAD Reflectivity
A little higher up in the sky, all the wind is almost due west, so as long as we have that disturbance kind of gluing things together, expect the snow to keep pushing well inland.  We get a bit of a break, but then a second Clipper breezes through tomorrow morning, so I expect snow more snow out of it.  1-2" here, more locally, especially west of US 131.  We get that out of here, then maybe just some flurries until Thursday, when we get another Clipper, and, you guessed it, another inch or two of snow.

TEMPERATURES:  Now that you know what we have for the week, temperature wise, it's a bit clearer picture.  First, I don't see any really nasty cold hitting us.  Seasonably cold and some single digits at night, sure.  We are in Michigan after all, and cold air likes to invade periodically.  Daytime highs will be in the 20's and then they start to trend a little higher mid week.  Climatology suggests an average temperature right at freezing, so we start under that, sneak up on it, then stay in the ballpark until early next week, when computer forecast models are thinking about upper 30's.  Too early to see if that holds water yet though.  We'll check it tomorrow and see what we get.

Here's a look at a current surface temperature plot...


And this is the 5 day precipitation forecast from the National Weather Service:
5 Day Precipitation Forecast

That .40" of liquid bullseye disappeared from up by Cadillac, but I still wouldn't be shocked to see around 4" of snow up that way over the next five days.  This map is good through 7 AM EST on Saturday.

Here's the forecast for Jackson and vicinity:

Today, cloudy, snow tapering off after lunch, high 21, winds N 5-10 MPH.  An inch or two of additional accumulation expected, some areas may pick up three inches of new snow.

Tonight, mainly cloudy, maybe a bit of light snow, very cold, lows down near 7, wind chills drop to around zero or even -5.  Wind N 3-7 MPH.

Tuesday, continued cloudy another Clipper heading in during the afternoon brings us a chance of more snow, perhaps up to 2" locally, most places closer to 1".  High 24, winds W 5-10 MPH keep wind chills in the teens.

Tuesday night, cloudy skies, snow tapering off after 10 PM, not as cold as Monday night with lows down around 10, winds W 5-10 MPH.

Wednesday, mainly cloudy, possibly a peek of sun, not as cold, high 25.

Thursday, cloudy skies, snow developing mid-morning, perhaps 2" in most places, some may be heavier, high 33.

Friday, a mix of clouds and a bit of sunshine, warmer still, high 32.

Saturday, partly sunny, high 35.

Sunday, periods of clouds and sunshine, high 37.

There's a look at you six day forecast, I hope that you have a great day!  Blessings.

Snowy Super Bowl Sunday!

Good Afternoon!

The snow that I forecast as just being light has intensified over the last few hours and become our familiar friend lake-effect.  Just take a look at the banding visible in the radar reflectivity image from the Grand Rapids NEXRAD.

Grand Rapids NEXRAD 
So, MOTS - More Of The Same.  Lake-effect snow, heavy west of 131, some of that reaching into south central Michigan and creating some headaches.

SUMMARY:  As I indicated before, ridge west, trough east in the upper air setup.  Northwest wind coming out of Canada and pulling cold air down with it.  Some embedded disturbances in the larger flow pattern.  Chilly northwest winds blowing across a slightly warmer Lake Michigan trigger lake-effect snow that is then carried across the state from winds blowing around 40 MPH or so at 5,000 feet above the ground. This is our setup in a nutshell for the next few days, and we keep it around at least through the middle of the week, when some changes start occurring in the upper atmosphere.

Forecast models mid week indicate that our flow will change to a more zonal pattern Wednesday night, with a few waves in it.  We warm up slightly as ridging tries to sneak some warmer air up this way, but I am less than thrilled with any real warmth making it this way.  All in all, I think we remain in the mid 30's from Wednesday through to the weekend.

SNOW:  With the lake-effect snow going on, we pick up 2-4" lake-effect aided inches in most spots of the blog, especially in the south zone tomorrow.  After that, a couple of Clipper systems Tuesday, and perhaps Thursday will bring us more snow.  Right now, two inches looks like a safe bet on the high side for the Thursday Clipper.  I fully expect to change it up a bit as we get closer to the tail end of the work week.  Here's what the National Weather Service thinks regarding precipitation for the next five days...

5 Day Precipitation Forecast
That .40" bullseye up around Cadillac looks interesting.  If that verifies, another six inches are possible up that way.

OK, here's the forecast for Jackson and surrounding areas including Grass Lake and Parma:

Tonight, cloudy skies, snow picking up in intensity late; 2-3" possible by morning drive, locally heavier amounts possible, low 12, wind chills near zero.  Winds become northerly 5-10 MPH.

Monday, continued cloudy, snow tapering off around lunchtime, high 21, winds N 5-10 MPH.  Up to an inch of additional accumulation possible.

Monday night, mainly cloudy, maybe a few peeks of snow, very cold, lows down near 8, wind chills drop to around zero.  Wind N 3-7 MPH.

Tuesday, cloudy skies continue, another Clipper brings us a chance of more snow, perhaps up to 2" locally, most places closer to 1".  High 23, winds W 6-12 MPH keep wind chills in the teens.

Wednesday, mainly cloudy, possibly a peek of sun, not as cold, high 28, wind WSW 6-12 MPH.

Thursday, cloudy skies, snow developing mid-morning, perhaps 2" in most places, some may be heavier, high 33.

Friday, a mix of clouds and a bit of sunshine, warmer still, high 36.

Saturday, partly sunny, high 36.

There's a look at your forecast for the next six days, i do hope that you have a great evening.  Enjoy the Super Bowl!  Blessings.

WINTER WEATHER ADVISORIES ISSUED...

The National Weather Service has issued a Winter Weather Advisory for Jackson, Calhoun, Branch, Hillsdale, Lenawee, and Washtenaw counties through 2 PM tomorrow.  2-4" of new snow is expected between midnight tonight and 2 PM tomorrow.  Expect a slick morning commute and reduced visibility while traveling.

Sunday Outlook...

Good Evening!

For the first time in recent days, we have no snow-related weather advisories on the map!  There's not much to see anywhere right now, except a thin line of precipitation out over Lake Michigan.  Right now we have mainly clear skies in Jackson, but they will cloud up again as we head toward daybreak.

SUMMARY:  Ridge/trough setup in the upper air over the US, so we get Clippers.  We don't get a whole lot of temperature variation, but for the next few days, you can expect an upper disturbance to zip through the area every 24-48 hours.  These little systems, called Alberta Clippers, will bother the atmosphere enough to stir up some snow.  You stand a chance at 1-2" of new snow each time one comes through, and right now, forecast data suggests that we'll see one tomorrow, Monday, and perhaps late Tuesday.  After that, any significant snow chances fade until Friday.

Temperatures stay right in the low 20's for daytime highs, with nighttime lows rolling back into single digit territory.   Wind chills shouldn't be quite as extreme as they have been, but still right around zero or even a little bit below.  Temperatures look to moderate, with a nice jump from right around 30 on Wednesday to almost 40 for Thursday and on into the weekend.  Here's the forecast for Jackson.

Today:  Mainly cloudy, chance of light snow during the afternoon, any snow that does fall should be light with accumulations about an inch, high 22.  Winds NNW 5-10 MPH.

Have a great Sunday!
