Rainy & Cooler To Start - Then Warming

Good Morning!

Periods of sun through a broken cloud deck greet us here in south central Michigan this Friday morning. We'll keep the clouds around, thicken them, and introduce some precipitation.  Let's have a look at what's going on.

COOLING AGAIN, THEN A WARM-UP:  We have a low pressure center in Michigan's upper peninsula, poised to track northeast into Canada.  That thing is dragging a cold front along with it, and when it comes through, it sends the mercury back into the low 70's, as opposed to the 76-80 degree range we should experience today.  It wouldn't shock me to see some spots come in under 50 for the nighttime lows tomorrow night, with daytime highs Saturday barely into the lower 70's!  As we peer through the binoculars into mid week, warming occurs as the troughing damps out in the upper air, and flat ridging allows warmer temperatures to ease in.  Nothing scorching mind you, seasonable readings around 84 is what I see right now.  Here's a look at what's going on temperature-wise across the nation:


KEEP THE UMBRELLA CLOSE BY:  For this evening and into tomorrow, you'll want an umbrella handy, because venturing out means you'll run into some raindrops.  The frontal boundary connected to the low I mentioned above will do some lifting of the air and create at least some showers and perhaps a couple of buried thunderstorms.  Not a washout for today or tomorrow, just know that you'll have a 30% to even money chance at rain the next 36 hours.  We note scattered showers northwest of a line from Benton Harbor to Midland.  Let's see what the Weather Prediction Center says regarding rain the next five days:


Not much more than three-quraters of an inch on the high side, that's been the story the last few days.  Most of that comes with the showers that I expect to become more numerous as the day progresses today into tonight.  We'll also have to see how much sun we get today , and how much atmospheric energy may be expended across the lake in Wisconsin, where the Storm Prediction Center has set up that area with a "slight" risk of severe weather for today.  Nothing like that forecast anywhere in Michigan.  That being said, expect the unexpected.  The best chance for rain looks to be from about 3 PM on, lingering into perhaps mid-morning tomorrow.  I am splitting the difference between multiple model solutions with that estimate, so bear it in mind.

Here's the visible satellite showing the clouds and such headed this way:


And here's the forecast for South Central Michigan:

Today, increasingly cloudy, some afternoon scattered showers develop, along with maybe a thunderstorm or two, high 79.  Wind SW 5-10 MPH.

Tonight, scattered showers become a bit more dense, lows near 60.  Wind becoming W 4-7 MPH.

Saturday, some lingering showers and possibly a roaming thunderstorm early, then partly sunny, cooler, high only 73.  Wind W 5-10 tapering off to 3-7 MPH.

Saturday night, mostly cloudy, a few peeks at stars possible, very cool, lows all the way down to 51.  Wind WSW 5-10 MPH.

Sunday, mainly cloudy, a couple of spots could see a hit & run shower, continued cool - high 68.

Monday, some peeks of sunshine mixed with clouds, we can't rule out an isolated shower, a touch warmer, high 73.

Tuesday, mainly sunny with some passing clouds, our warmer air starts working in, high 79.

Wednesday, partly sunny skies, seasonably warm.  High 82.

Thursday, nearly a carbon copy of Wednesday, mixed sunshine and seasonable, high 84.

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