Big Changes...

Good Evening!

The temperatures have started to fall as advertised, and the rains are working into the area.  Any place that is dry now will not be in the next hour or so.  A couple of wrinkles have been added to the mix:

WINTER WEATHER: A Winter Weather Advisory has been posted by the National Weather Service until 11 AM tomorrow for Calhoun, Jackson, Eaton, Ingham and Clinton counties.  What's expected to happen is that as temperatures fall below freezing tonight, rain will change to freezing rain, then to light snow.  Icing will be an issue also.  As much as three-tenths of an inch of ice is possible in some areas by daybreak, with around an inch of snow on the high side throughout the area.

FLOODING:  The National Weather Service has also issued a Flood Watch for Branch, Hillsdale, Lenawee, Washtenaw and Livingston Counties until 10 AM tomorrow.  Temperatures in this part of the state are expected to remain sufficiently above freezing that steady moderate to heavy rain will be the precipitation mode, and some flooding or flash flooding is possible.

If you are in the far southeastern part of the South Zone, please watch for rain/flooding and fog tonight.  The rest of the blog needs to look out for rain changing over.

We'll keep monitoring the situation and update as needed.

FLOOD WATCH

The National Weather Service has issued a Flood Watch until 10 AM Sunday for Hillsdale, Washtenaw, Livingston and Lenawee Counties, due to heavy rain associated with a low pressure system and cold front heading into the area.  Heavy rains develop tonight, 1 to 2 inches possible in southeastern Michigan, and this combined with snowmelt could pose a problem.

WINTER WEATHER ADVISORY

The National Weather Service has issued a Winter Weather Advisory for Jackson, Clinton, Ingham, Eaton and Calhoun counties starting at 10 PM tonight.  Rain changes over to freezing rain and snow showers thus creating slippery driving conditions.  Use caution if traveling!

So Long Spring Preview....

Good Morning!

Enjoy the spring weather while we have it, because once the temperature starts sliding backward, we don't see this mild weather again anytime soon.  Let's dive right into it while it's warm (pun intended).

SUMMARY:  Unseasonably mild air is in place over the area right now, and we have a surface set to make tracks this direction from the southwest.  It will track right over Illinois, Indiana and Kentucky, with the core of it sliding into far southeastern Michigan and northwest Ohio.  Adrian, Temperance, Toledo.  That part of the world.  A couple of peeks of sun mix in with the clouds, then we get into the precipitation later today and into tonight.  Temperatures run 20+ degrees above average for this time of year, and I could see a record being threatened.  Just as an FYI, record high this date for Jackson is 59 degrees, set over a century ago in 1898!  Lansing's record high this date is 62, in 1890.

Once we get through today and tonight, we drop back to reasonable temperatures, topping out in the mid 30's.  A cold polar air mass finally elbows it's way into the area...

NAM Forecast model, 4 PM Today

NAM Forecast Model, 4 PM Sunday
This may force temperatures into the 20's on occasion, but you have to understand that our average according to climatology is 30 degrees, so even mid 30's is above average.  We'll take it!

PRECIPITATION:  We start off with some sprinkles later today that fill in and become rain showers, then we change to snow showers as the mercury falls over the next 24 hours.  With the moisture in the air, also expect some fog about this evening, so use caution as you drive.  After that, not really much chance of anything until hump day next week.

Here's a look at the forecast for Jackson and surrounding areas including Rives Junction and Michigan Center:


Today, mainly cloudy skies, perhaps a peek or two of sun, afternoon showers develop, unseasonably mild still, high near 57.  Winds swing from southwest to NW 5-10 MPH.

Tonight, cloudy with scattered to numerous showers, temperatures fall sharply to a low near 35, winds NW 8-15 MPH.

Sunday, overcast, plenty of showers through early afternoon with maybe a bit of snow mixing in, high 38.  Wind W 8-15 MPH.

Sunday night, clouds thin out as the night progresses, giving us a view of some stars, seasonably cold with lows down to 19.  Winds W 9-16 will keep wind chills in or near single digits.

The new work week on Monday brings partly to mostly sunny skies, colder, high 30.

Tuesday, partly cloudy, continued seasonably chilly, high 31.

Wednesday, mostly cloudy skies, we can't rule out a few flakes or some light snow, high 35.

Thursday, skies continue mainly cloudy, we keep the mention of a flake or two around, high only 33.

Friday, still not much in the way of direct sunshine, mostly overcast, high 36.


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

Old Man Winter Returns Soon...

Good Evening!

Well, if I am going to own a busted forecast, I will certainly take this kind of a bust!  The rain that came in over night moved out of the area quicker than forecast.  We were partly to mostly sunny with temperatures pushing 60 in a lot of places.  I should have stayed with my first read of the forecast data and left the high up at 56 today.  Oh well.

SUMMARY:  Some good, gentle, soaking rain moved in and out of here today, and we had clear skies.  These are now clouding up, and we may see a sprinkle or two during the overnight hours.  As for tomorrow, we enjoy more unseasonably mild weather.  We are almost 30 degrees above average here in Jackson!  Take a look at the current temperatures right now...


Look at that mild reading for the "cold" spot - 45 in Adrian at this hour.  I suggest that you enjoy it, because the bottom falls out of the thermometer on Sunday, with temperatures giving back every inch of that almost 30 degree surplus and then some!  Plan on temperatures not making it back to the freezing mark for at least the next week to 10 days.

PRECIPITATION:  Our next weather maker comes in on Sunday as a surface low moving this way from Arkansas and Tennessee.  That will kick off another round of showers that will change to a wintry mix and then all frozen precipitation as it moves this way and then heads off.  Take a look at this forecast map from the GFS computer model, you can see where the cold stuff will be on Sunday afternoon...

NAM Forecast Model, 4 PM Saturday.  Notice the sharp gradient of falling temperatures just behind where the cold front is marked here.

The good news is that after Sunday, we keep snow pretty much off the table for the next week, as far as I can see.  We'll have our first extended cold snap of the season as a Polar Express marches through Canada and then dives into the US.

Here's a look at the forecast for Jackson and surrounding areas including Grass Lake and Leslie:

Tonight, partly to mainly cloudy and mild, perhaps a brief stray shower, lows roll back to 42, winds SSW
5-10 MPH.


Saturday, partly to mainly cloudy skies, clouds thicken and some showers are possible in the afternoon, milder still, high near 57.  SW winds work around to the NW 5-10 MPH.

Saturday night, cloudy skies, scattered showers and cooling quickly, lows near 35, winds NW 8-15 MPH.

Sunday, cloudy, scattered showers with maybe a bit of snow mixing in, high 34.

Monday, partly to mainly sunny skies, colder, temperatures top out near 30.

Tuesday, partly cloudy, high 30.

Wednesday, partly cloudy skies don't really go anywhere, we add a small chance of a few flakes or some light snow, high only 33.

Thursday, skies continue mainly cloudy, we keep the mention of a flake or two around, high only 30.

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

Here It Comes...

Good Evening!

With the chance to look at some data, a few changes are in the offing for the forecast, so we'll talk about those and tell how things will shape up through the weekend and into next week.

First off, the rain is lurking.  As our disturbance and upper low makes it's way into the area, a good sized body of showers is tracking in from the southwest.  Earlier in the evening, radar indicated that there may be some heavy showers or even an embedded thunderstorm.  Let's look at the radar and see what we have right now:

Grand Rapids NEXRAD Reflectivity Image
As you can see a pocket of radar indicated heavy rain is over Jackson as we snapped this image, but remember that the radar is seeing a few thousand feet up.  That is light to moderate rain here on the ground at the moment.  Once that gets in and starts raining on us, we'll get a good soaking out of it.  Temperatures will remain fairly steady throughout the overnight hours, and I would not be at all surprised to see some good rain amounts here.  Let's look at the National Weather Service forecast map and see what's there...

National Weather Service 24-Hour Precipitation Forecast
This map is valid at midnight tonight.  As you can see, a good soaking is in the offing, with almost an inch and a half of rain at the high side, and right around an inch across the board throughout the blog area.

Here's a look at the forecast for you for tonight:


And this is the six day outlook for you:


Heads up...back into the freezer on Sunday!  Have a great evening!

Shades Of Spring Through Saturday...

Good Morning!

Another gorgeous start to a Thursday here in Michigan, BUT....the clouds and rain are coming, no two ways about it.  Let's get a quick summary and then show you the forecast:

SUMMARY:  Temperatures continue several degrees above normal for today, right through Saturday.  Daytime highs in the area will trend anywhere from 10 to almost 20 degrees above normal.  Today we'll be in the mid 40's, upper 40's or even low 50's Friday, then mid to upper 50's on Saturday.  After that, expect the temperatures to almost halve themselves, and we change from rain back to snow as the precipitation mode.

PRECIPITATION:  With respect to rain, we'll see clouds thicken as the day progresses, and we'll mention the chance of a stray shower in the early evening, but I fully expect our rain to start well after dark.  I would suspect that most places shouldn't start getting wet until Thursday Night Football is done or late in the game. Currently that rain is in central and southern Indiana, and it will slowly make it's way northeast.

The rain sticks around most of the day Friday, and I must admit that I am wrestling with leaving in the forecast a mention of a buried thunderstorm or not.  While surface temperature is certainly warm enough to support the development of storms, what's going on overhead and how that is forecast to lay out has me less than enthusiastic about the possibility.  For now, it stays in, but don't be shocked to see the forecast change to just rain, locally heavy at times.

Alright, forecast for Jackson and surrounding areas including Parma and Grass Lake goes like this:


Today, partly to mostly sunny starting out, increasing clouds as the day progresses.  Perhaps an isolated afternoon shower, high 46, winds ESE 5-10 MPH.

Tonight, cloudy skies, rain by midnight, lows near 34, winds SE 5-10 MPH turn southerly toward daybreak and increase to 10-15 MPH.

Friday, cloudy and rainy, continued unseasonably mild, high 53.  Wind SSW 7-14 MPH.

Friday night, rain ends, cloudy skies and unseasonably mild, low only 42, winds SSW 6-12 MPH.

Saturday, a mix of clouds and sunshine, an outside chance of a lingering shower, milder still, high near 57.

Sunday, clouds, scattered to numerous showers with maybe a bit of snow mixing in, high 39.

Monday, partly cloudy skies, we can't rule out an isolated snow shower or some light snow, high 30.

Tuesday, overcast, scattered showers or even snow showers linger in the area, high 30.

Wednesday, clouds don't really go anywhere, we keep a small chance of a few flakes or some light snow, high only 33.

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

Warming Still, Rain Forthcoming...

Good Evening!

Time to see what fresh weather data brings us in the way of the forecast, and look at a couple of other things with you.  First, we are running 10-15 degrees above average at this point, and we'll widen that gap some between now and Saturday.  Take a look at this current temperature plot:


Adrian checks in as the warm spot with 41 degrees, a couple of 38's on the board along the I-69 corridor.

SUMMARY:  Jackson logged a high of 46 today with a smidgen of rain early this morning, and Charlotte was the warm spot in the blog, with a high of 47.  That's over 15 degrees above average and the mercury just keeps moving upward tomorrow, into the weekend.  Chilly tonight, mainly clear skies with just a couple of passing clouds allow us to lose our daytime surface heating back into the atmosphere, so we see temperatures drop back to the 20's, with wind chills in single digits or the lower teens, at least until the winds die off some.

Sunny to start tomorrow, then clouds start increasing after lunch as an upper disturbance eventually scoots up here from the Plains and triggers some rain showers with maybe even a thunderstorm.  I expect rain to not show until after dinnertime, you should be able to make it home with dry conditions.  Thursday night and into Friday, we'll see numerous showers and maybe mention a potential storm, these persist through mid-afternoon Friday.

Daytime Saturday looks OK, then late Saturday into Sunday, here comes the next system, and the mercury plummets.

Here's the forecast for you:





A Brief Winter Break...

Good Morning!

Temperatures are already up into the 30's today, but you wouldn't know it based on the feel.  Stiff SW winds are making things feel cooler than they actually are, as we start this hump day Wednesday.  Let's take a closer look and see what we have going...

SUMMARY:  After a line of hit and run showers moved through the area during the pre-dawn hours, we have sunshine aplenty on tap for today.  High pressure building into the area brings us southwesterly breezes, and we get temperatures climbing into the mid 40's.  You haven't seen anything yet though, forecast models are suggesting temperatures in the middle 50's for Saturday!  After that, forecast models suggest that we get shoved into the freezer for awhile.  Don't get spoiled!  It is January in Michigan after all.

PRECIPITATION:  Too warm for snow over the next several days, so anything that we get will be rain.  Friday will be wet, with rain during the day, this looks like a good soaker that will help beat away some of the snow that is still on the ground from the day after Christmas.  I will mention the outside chance of a thunderstorm on Friday as well, based on forecast modeling at this point.  We'll need to see some moisture and a couple of things line up in the atmosphere to get them, but just file it away as a possibility at this point.  Saturday may have a brief lingering shower, then we get a break until Sunday when another system being pulled by a surface low tracks into Michigan.  Sunday's temperatures will be anywhere from 10 to 20 degrees cooler though, so don't be surprised to see a freezing mix or snow with that system.  After that, cloudy skies, seasonably cold temperatures, and a switch back to the right kind of precipitation for this time of year - snow.


Today, sunny, unseasonably mild, high 43, winds SW 7-14 MPH.

Tonight, clear skies, chilly, lows roll back to 23, winds turn southeasterly, 4-10 MPH.

Thursday, sunny to start, increasing clouds as our weather system approaches.  Perhaps a couple of scattered afternoon showers, high 44, winds ESE 5-10 MPH.

Thursday night, cloudy, rainy, lows near 34, winds SE 5-10 MPH.

Friday, cloudy skies, numerous showers, continued unseasonably mild, high 53.

Saturday, cloudy skies, we can't rule out a few lingering showers, milder still, high near 55.

Sunday, some scattered showers with perhaps some snow mixing in as a surface low tracks into the area, high 41.

Monday, cloudy skies, some scattered snow showers or even light snow, high 35.

Tuesday, still overcast, scattered showers or even snow showers linger in the area, high 35.


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

SPECIAL WEATHER STATEMENT - Black Ice Advisory

The National Weather Service in Grand Rapids posted a Special Weather Statement for black ice/slick spots in areas due to a quick hit of light rain that fell earlier, and the roads were near or below freezing. 

Jackson, Calhoun, Clinton, Eaton, Ingham counties use caution while.driving and be ready for black ice this morning!

Quiet & Mild For Awhile...

Good Morning!

A new work week is upon us and the holidays are now officially over for those of us with kids, as it's back to the grind and back to school for a lot of children, at least here in Michigan.

As far as what's going on overhead, not a whole lot to talk about over the next few days.  Hazy sunshine in the area at this hour, some clouds off the the east and clear skies moving in from the west, most reporting stations floating in the mid to high 20's.  Here's a look at the current surface temperature summary for the good old U.S. of A...


It's not frozen right now, so we'll pop the hood and see what we have running in there!

TEMPERATURES:  High pressure is parked over the IN/OH/KY region, and the flow around that feature is bringing us milder, moister air from the southwest. With multiple high pressure features meandering about near us, we'll see prime snow melt weather for the next several days, and temperatures marching upward steadily as we work toward the weekend.  Our fearless GFS computer forecast model is thinking we'll see 49 for a daytime high on Saturday!  It looks like we'll also string together a few days where we stay above freezing all day and all night.  We'll see if that verifies or not, but in any circumstance, we'll see unseasonably mild conditions for the next several days here over South Central Michigan.

PRECIPITATION:  Nothing of interest to mention over the next few days, except periods of clouds and sunshine.  With the melting snow and mild temperatures, keep your eyes open for overnight and early morning fog, and be prepared for slick spots as wet pavement freezes over, creating some black ice situations, especially on untreated roads.

The next real chance at some precipitation will be Thursday afternoon and evening, and carrying into most of Friday.  An upper feature starts to cloud us up Thursday after lunchtime, then we see scattered to numerous showers develop from southwest to northeast across the area during the balance of Thursday.  I'm thinking we'll get the morning and lunch commutes out of the way in dry fashion, with perhaps just a lone shower as you get the kids from school or off the bus.  Some showers on the way home from work, then we get a good soaker in after dark.  Take a look at this forecast map and you'll see what I'm talking about...

GFS Forecast Model Map for 7 PM EST Thursday
Even with temperatures up near 50, at this point, I don't see any reason to consider anything beyond rain and showers.  The atmosphere shouldn't be unstable enough to allow anything with thunder to develop.  It's winter, and the air is too cold and sinkable near the ground and a ways up.  You need moist, floaty, unstable air among other things to kick off storms.

Infrared satellite imagery shows not much at all in the way of clouds in the Midwest this morning...

Infrared Satellite Picture
Now let's look at the forecast for Jackson and surrounding areas including Rives Junction and Spring Arbor:

Today, mostly sunny with a few passing clouds, high 36, winds SSW increasing to 7-12 MPH.

Tonight, periods of clouds and stars, low near 25, wind S 5-10 MPH.

Tuesday, again, mainly clear skies with a few clouds floating by, high 39, winds S 5-10 MPH.

Tuesday night, more starry skies, perhaps a cloud or two, lows roll back to 27, winds become W 6-12 MPH.

Wednesday, sunny, unseasonably mild, high 43.

Thursday, sunny to start, increasing clouds as our weather system approaches.  Perhaps an isolated afternoon shower, high 38.

Friday, cloudy skies, scattered to numerous showers, continued unseasonably mild, high 44.

Saturday, cloudy skies, we can't rule out a few lingering showers, milder still, high near 50.

Sunday, periods of scattered showers as another upper impulse moves through, not as mild, high 41.

There's your six day forecast, I do hope you enjoy your Monday!  Blessings.

Quick Look For Tonight & Monday

Hello!

After a two day working vacation of sorts (too bad it's wasn't all fun), I am back quickly while the laundry is drying to give you an outlook for tonight and tomorrow.



More details to come later this evening and tomorrow!
