Summer-like, Then Cooler...

Good Morning!


A beautiful day on tap for South Central Michigan today with sunny skies and seasonable temperatures, but then tomorrow,  scattered to numerous showers and thunderstorms look to move in, and some of those could be elevated, which means they'll blow hard and possibly drop some small hail.  Let's take a look and see what we have.


TEMPERATURES: We'll see temperatures right around where they should be for the weekend, but then they take a bit of a nosedive on Monday, as the upper air pattern brings us a good shot of cool air from up in Canada.  Temperatures look to run about 10 degrees cooler for  Monday into Tuesday, with computer modeling suggesting daytime highs in the 70's for Monday and Tuesday.  After that, we get back into the summer-like middle 80's that are more the norm for this time of year.


RAIN:  The rain forecast looks like a twin-barreled event, with one shot early Sunday morning, then a better chance late Sunday afternoon or evening.  For my money, I'm inclined to hang my hat on the evening event as the better of the two.  I am forecasting isolated to widely scattered for the early chance, then for the afternoon and evening the coverage should be a little more widespread, so I will call it scattered.  After that, we stay pretty dry until the end of the month, when we have our next best chance at rain.


SEVERE WEATHER:  While the Storm Prediction Center doesn't have us with anything severe, for Sunday, they do introduce some low end 5% chances for rough weather, with the primary threat being elevated storms with strong straight-line winds and perhaps some small hail.  You can thank a cold front coming down the back side of the big ridge in the central part of the nation for that.  Out ahead of it in an air mass with temperatures in the 80's, some storms are expected to fire.  We'll have to see what kind of unstable they can get hold to, as that determines how strong they'll become.


Bright blue skies in Jackson right now with variable winds, here's the local forecast for Jackson and surrounding communities including Grass Lake and Parma:



Today, mainly sunny, maybe a couple of passing clouds, high 81, variable winds up to 6 MPH.


Tonight, partly cloudy skies, a bit milder than Friday night, lows roll back to 58, winds SW calm to 5 MPH.


Sunday, partly sunny skies, a chance of a widely scattered afternoon shower or pop-up thunderstorm, high 83.  Winds SW 7-14 MPH.


Sunday night, continued periods of clouds and stars, chance of a scattered shower or storm, lows down to 53, winds swing to the NE 5-10 MPH.


Monday, sunny, much cooler, pleasant, high 74.


Tuesday, mainly sunny, seasonable and nice, high 77.


Wednesday, a rewind and repeat of Tuesday.  Sunny and pleasant with a high of 78.


Thursday, periods of clouds and sunshine, warm, high 86.


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

Quick Update...A Small Chance Of Rain...

Good Evening Friends!

Just had a rare early evening chance to look at some data and radar, and I see enough to change the forecast slightly for tonight.  What we've got now is a couple of rogue thunderstorms firing out over Lake Michigan, and some small showers further inland and tracking southwest.  Right now the smaller stuff is currently in west Michigan, and it looks as if they are falling apart as they move deeper over land and into the drier air, but here in the blog zone, we may see a couple of stragglers that manage to form up and fire briefly later on.

Your updated forecast for tonight is partly cloudy skies, we'll add in a chance of an isolated or widely scattered shower, perhaps a lonely thunderstorm, nighttime low of 53 with NW winds 5-10 MPH.

More on this tomorrow, but computer forecast modeling indicates we may have a crack at some showers before daybreak again on Sunday, then perhaps a more substantial threat late Sunday night into Monday.  That will depend on how close an upper disturbance tracks to us as it slides off the back of the ridge that will keep the Plains hot and high ninety-ish for the next few days.  We'll check it out and forecast it for you tomorrow!  Have a great evening!  Blessings.

Strong Wind Shift Advisory - Livingston, Washtenaw

The National Weather Service has issued a Special Weather Statement for a strong wind shift for Livingston and Washtenaw Counties.  Winds over 30MPH are moving in from northwest to southeast, and may cause small objects to be blown around, so secure anything you don't want blown away.

Nice Weekend In The Works...

Good Morning!


TGIF!  We've almost made it through another work week, and the weekend is creeping closer by the minute!  It looks to be a pretty nice one once we get through today and a tiny lingering shower threat.  Let's take a deeper dive and see what we have on tap...


TEMPERATURES:  With a trough-ridge-trough pattern starting to emerge over the US, we'll see temperatures much more moderate as compared to recent days.  Humidity will be down some as well, with drier air working into the area.  Temperatures will top out at around 84 degrees for a few days, then late next week, we'll see winds shift and come in more directly from the west as opposed to making a detour up through Canada and coming in from the northwest.


RAIN:  The dryness continues over South Central Michigan for the next few days, as we really don't pick up much of anything according to the National Weather Service for the next five days.  Considering that we don't really have any weather systems poised to pay us a visit the next few days, this 5 day precipitation map from the NWS looks like a good bet from here:


5 Day Precipitation Forecast
As you can see, basically nothing in the forecast, perhaps a brief stray shower but that's about it.


SEVERE WEATHER:  The Storm Prediction Center doesn't expect much in the way of severe weather for us for the weekend, which is a good thing.  We've got a "general" risk just north of us for today, so I need to mention that a rogue thunderstorm or two may fire and cruise through, but anything that does happen, shower or storm, will be isolated.  Day three, SPC has us in a 5% chance for severe weather, so we'll need to keep an eye on it.  Here's the forecast maps for days one and three, valid at 8AM EDT as always.

Nothing on the infrared satellite image this morning, and the Grand Rapids NEXRAD is quiet, those heavier green returns you see are ground clutter and some dense fog that is lingering in the area.

Here's the local forecast for Jackson County:



Today, mostly sunny skies with a couple of passing clouds, high of 80, winds NNW 5-10 MPH.


Tonight, mainly starry skies with a lone cloud or two floating by, low 54, winds NNW 3-8 MPH.


Saturday, mainly sunny, perhaps a few clouds, high 81, variable winds up to 6 MPH.


Saturday night, a mix of clouds and stars, a bit warmer than Friday night, low of 58, winds SW calm to 5 MPH.


Sunday, partly sunny skies, a slight chance of an isolated or widely scattered afternoon shower or pop-up thunderstorm, high 83.


Monday, sunny, much cooler, pleasant, high 74.


Tuesday, mainly sunny, seasonable and nice, high 77.


Wednesday, a rewind and repeat of Tuesday.  Sunny and pleasant with a high of 78.


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