Quick Look At Friday

Good Morning!

A pleasant surprise to start the day today - SUNSHINE!  I certainly didn't expect to see some quite so soon, but we'll take it!  Don't worry though, clouds will return later today.  It's looking like the clouds won't be quite as stubborn as originally thought.  Let's take a deeper dive.

CHILLY FOR TODAY & PART OF SATURDAY:  Cold Canadian prompted Frost Advisories in the area for last night.  I hope that your plants came inside or are hardy enough to deal with it!  That being said, there's a change to discuss regarding temperatures.  Forecast models have reversed course, looking to bring a 60 or two into the area for tomorrow instead of waiting until Sunday.  There's an upper low on the satellite picture, sitting over Illinois and Missouri as I write this, with high pressure behind it up closer to Canada.  The thinking now is that the low just kind of fades away, but the high pressure behind it gets pulled down into the upper flow, keeping skies clearer than advertised yesterday, allowing sunshine-fueled warming.  Behind that, ridging with warm air from the southwest building in.  Add 'em up, and you get warmer readings a bit faster than I stated yesterday.

A FAIRLY DRY STRETCH ON THE WAY:  Forecast data says we can expect a fairly dry stretch of days to come here in this part of Michigan.  South Central Michigan looks pretty quiet, with just some passing clouds and maybe a stray shower this afternoon and tomorrow afternoon.  In other words, your typical springtime hit and run PM shower through tomorrow, then a dry stretch if this models have a grasp on things.  No severe weather or even thunderstorms to speak of for the next three days in this part of the world.

Here's the forecast:

Today - Mixed sunshine early then becoming cloudy, a couple of stray showers.  Chilly, high 53.  Wind NW 5-10 MPH.

Tonight - Periods of clouds & stars, perhaps a quick shower.  Lows near 35, winds NW 4-8 MPH.

Saturday - Mainly sunny, a bit warmer, some spots could see a stray shower, high 60.  Wind WSW 5-10 MPH.

I'll have more detail for you later!

Gray & Gloomy For Awhile...

Good Morning!

A damp & chilly tail end of the week is in store for Michigan - we'll start recovering early next week if everything plays out as advertised right now.  One deeper dive to talk about it all coming up below...

DAMP START TO THE DAY:  A good potion of the state awakened to rainy conditions this morning, I expect that to continue later today after the break we're in now, as most of the western half of Michigan is getting a breather from the rain, with the exception of a light shower here and there that radar may have a hard time seeing. Don't expect any change in pattern just yet though, as we'll turn the rain back on with a couple of spotty showers mid-afternoon.  Here's the current Tru-Track Doppler radar image:

Plenty of clouds, but a chance to dry out a bit if you're not in the thumb.  A fresh line of showers is across the lake and on the move, we'll see how it survives the trip over Lake Michigan.
Current short range data is telling me that the encore shower performance this afternoon should be light and widely scattered.  That being said, toss the umbrella in the car with you - I'm thinking the line shown in the radar image may hold together a bit better than the models are saying it will as it comes east.

HOW MUCH RAIN THE NEXT SEVERAL DAYS?:  The main low pressure system that brought us storms and the rains today is tracking northeast as I write this.  You can pick out the center of the low and where the front is if you look at the radar/satellite composite and check the temperatures, as there's a 8-14 degree swing from warm to cold side.  Regarding rain totals, the Weather Prediction Center says that today should about do it for copious rain for awhile.  Have a look at the 5 Day Precipitation map...


Rain amounts should stay below a half-inch in Michigan if you're not in the thumb.

WELL BELOW AVERAGE TEMPERATURES FOR AWHILE:  As we get this low pressure center, the associated cold front, and the rain through and out of here, Canadian air rolls in on northwesterly winds, keeping us about 20 degrees below normal.  Average readings in South Central Michigan are right around 72 degrees.  Nights will require a light blanket, with low temperatures flirting with the freezing mark. The forecast models aren't showing me a 70 or better daytime high until next Tuesday!


Now that you know the details, here's the forecast for Jackson and surrounding communities including Grass Lake and Parma:




And here's the extended outlook for us:


Bear in mind that there is a chance of a lone shower or two Friday, even though I didn't put a percentage on the graphic.

I hope you have a wonderful Thursday!  Blessings.

Clouds & Cooler...

Good Morning!

We welcome a gray, damp day into the area, and I hate to say, but this is about the last day of seasonable readings in the area until early next week.  Let's get right into it and see what's running under the hood:

COLD FRONT IS BY, CHILLY CONDITIONS AHEAD:  Yesterday's showers and thunderstorms were out in advance of a strong trough and cold front moving this way from out west.  The big picture is a definite ridge/trough/ridge setup with the middle 60% of the US being influenced by the trough digging a ways south into the nation, pulling colder air down from Canada.  Jackson made it to 81 officially at the airport yesterday, comparing favorably with my forecast high of 80.  We'll give back about 25 degrees of daytime high over the next 24 hours, with the highs today topping out in the low to mid 60's, and a struggle to hold on to the upper 50's until late in the weekend.  Your nighttime lows will dip to near freezing over the next few nights!  Starting Sunday we begin to see more seasonable air filter in, with readings back into the 60's.

Here's the current temperatures as I write an early morning post for a change:


The readings say it all, but they don't tell you about some...

SHOWERS AND SUCH:  This slow moving boundary will bring us periods of showers and perhaps a thunderstorm or two, keeping the skies cloudy and conditions damp today.  The main body of storms is off to east and southeast, stretching from western New York, back south through PA, OH, WV, and eventually making it down into Dixie.  Those areas are in the standard "slight" risk for severe storms today.  Here's that map:


The next piece of the rain train is a strong shortwave located down around the ArkLaTex, organizing itself into a legitimate surface low and coming this way.  That arrives as a surface low tomorrow.  In front of it, as with most low pressure systems, clouds with rainy conditions.  When it gets here, it sits on top of us for awhile, so while there will be an occasional break from rain, clearing doesn't really take hold until tomorrow evening and into Friday.

A few clouds persist from Friday on, and I have to toss in the mention of the chance of a stray shower or two through at least Saturday.

BACK TO MAY-LIKE WEATHER NEXT WEEK:  Starting Sunday, we'll see some warmer conditions as the ridge currently sitting just on shore out on the west coast will have started a progression east, elbowing the colder air out of here and bringing back warmer readings, back into the mid and upper 60's.

Here's the forecast for Jackson and surrounding areas including Concord and Rives Junction:




I hope that you have a great Hump Day!

I Thought The Calendar Said May...

Good Morning!

After a busy weather day yesterday, things have quieted down somewhat, but they will get busy again in time, with another round of showers and thunder, fortunately not as intense as yesterday.  Let's take a deeper dive...

NO HUGE DEAL SEVERE-WISE:  Yesterday we were in a "slight" risk for severe weather, and boy did it verify in Washetnaw COunty and points east!  Tornado warnings, hail, all of that.  Today, things should be much quieter, even if not storm-free.  Have a look at the Storm Prediction Center risk map:

SPC Day 1 Risk Map
As you can see, just a general risk for garden variety thunderstorms today.  That being said, we could see some hail up to pea-size and a some gusty winds as well.

MORNING SUNSHINE, SHOWERS AND A STORM LATER:  We note clouds working into the area from the west at this hour on the visible satellite image, as they do, and you combine that with the heating we're getting right now and will continue to get, you can expect some scattered showers and thunderstorms sometime after 2 PM.  Even though the air is pretty worked over from all the storms yesterday, thanks to the low-level jet pushing more moisture in ahead of this upper disturbance, it will recover some to support showers and new storms.

A BREAK IN THE ACTION, THEN THE ENCORE:  Showers and storms persist into tonight and perhaps as late as morning drive tomorrow, then we see a break in the action until the main weather maker shows up.  That's a low tracking northeast from IN/KY/OH, and that's the one that will bring us another round of showers and thunderstorms, but it also bring us sharply cooler weather.  I hate to say it, but we are coming to the end of our seasonable weather for a few days. Normal temperatures run into the lower 70's here this time of year, we'll be on the order of 20 degrees cooler!  Here's the current temperatures around the nation:


Now have a look at the NAM forecast model futurecast regarding temperatures:

This is valid Thursday at 8 AM.  Nowhere CLOSE to what we're seeing now!
That's chilly Canadian high pressure!  We'll clear the skies and it will feel more like early Spring or even Fall than knocking on the door to Summer with Memorial Day just a couple of weeks away!

RAINS HERE AND THERE:  Here's what the Weather Prediction Center thinks regarding rain totals for the next five days:


That's a pretty tight gradient there, showing two things: 1) the better chances for rain and storms will be confined to southeast lower Michigan and 2), those rains will have a bit of intensity with them.  Showers and such that form will wring themselves dry fairly effectively over this area.  As you track back northwest, the rainfall amounts drop sharply.

Here's the forecast for Jackson and vicinity:



And here's the extended outlook...


Have a great day!  Blessings

Noisy, Blowhard Storms Later...

Good Morning!

A potentially busy day for us here in South Central Michigan so let's have a look and see what's cooking!

RIGHT NOW:  Plenty of shower and thunderstorm activity to be had - here's Tru-Track Doppler:


You can see the broken line of storms stretching from Adrian back northwest up to Big Rapids.

SEVERE WEATHER CHANCES:  The Storm Prediction Center has placed us into the standard "slight risk for severe weather.  Here's a look at the detail on that:


Thankfully, no moderate risks on the map like there were yesterday, resulting in several tornadoes across Nebraska and Kansas.  The primary threats from these storms for us later today will be small hail, gusty straight line winds and locally heavy rains.

I will have a detailed forecast for you by 1 PM!
