Hold Your Hats, Grab Your Jackets!

Good Morning!


Windy and springlike in Jackson...for now.  Temperatures will take a nosedive today as a strong surface low escapes the US and tracks into Canada.  It's centered over northwestern Wisconsin.  In fact, under that surface low, it is SNOWING there at this hour.  I don't expect us to see any of that, though it surely will be cold enough to snow by late tonight and into tomorrow.  


Elsewhere around the US, the Plains continue to pick up the pieces from the weekend's severe weather event through Tornado Alley.  Regrettably, there is now a 6th fatality from the Woodward, OK tornado.  This is why you need a weather radio or something indoors to warn you that a tornado may be coming through your town.  Though I talk somewhat tongue-in-cheek about tornadoes "visiting", etc., it really is NOT a laughing matter.  Several professionals, including meteorologists and emergency management specialists have weighed in, saying that had those people gotten timely warning AND had a plan, they might be alive today.


Let's take a deeper dive into the area weather picture:


TEMPERATURES:  We'll start the day in the 60's, then watch the mercury slowly fall as a fairly muscular surface low tracks up through Wisconsin and the Upper Peninsula, before escaping north of the border.  We actually get twin barreled action from that.  We had an upper level wave push through early this morning, kicking off some showers and embedded thundershowers.  That's gone, with STRONG south winds behind it.  The surface low movement turns the winds westerly and starts the cool down.  Another upper-level wave comes through, possibly triggering a few more showers, and then a cold Canadian high settles in behind that.  We'll struggle into the mid 50's tomorrow, but then temperatures rebound a bit as we get a bit of warmer southerly flow back.


RAIN:  The models seem to like the next chance for rain to come on Wednesday evening, as another upper disturbance tracks through the northern part of the Lower Peninsula, but close enough that it could trigger a shower or two.  After that, we'll keep a chance of rain in the picture into the weekend.  Here's the 5-day rain totals as predicted by the National Weather Service.  We'll come in around an inch, give or take, during the next 5 days.




SEVERE WEATHER:  Not here.  Here's what the Storm Prediction Center is saying, remember these maps are valid at 8AM each day:



Thankfully, things look to have settled down.  The "slight" risk is well off to the east of us, and just a "general" risk in the eastern part of Michigan.  After that we should be in the clear. No storms forecast anywhere on the third day.


Here's a look at the satellite image, and radar from Grand Rapids.





Not much, that circle is ground clutter around the radar in Grand Rapids.  Just a few light showers over Detroit and Windsor, Ontario, leaving the area.


It's time for the local forecast for Jackson and vicinity.


For today: High Wind Advisory in effect until 10PM.  Periods of clouds and sunshine with a chance of a scattered shower or two, perhaps an embedded thundershower hiding as well.  High temperatures near 66 but falling, winds SW 25-35 MPH but gusting to 45 MPH or better at times, also turning northwesterly toward evening.


Tonight: still a slight chance of scattered showers early, then cold, nighttime lows near 36, winds slow to NW 20-30 MPH, then taper off further to 10-15 MPH after midnight.


Tuesday morning: we could see some scattered frost, mainly clear and much cooler, high near 55.  NW winds 7-15 MPH.


Tomorrow night: mostly starry skies, chilly, frost possible, nighttime lows roll back to 34, NW winds 5-10 MPH, tapering off as the night progresses.


Wednesday: Sunny, warming nicely after a chilly start, temperatures near 70, winds S 5-10 MPH.


Thursday:  A mix of clouds and sunshine, with a chance of scattered showers, high near 63.


Friday: Mainly cloudy, cooler, a 40% chance of rain, high 55.


Saturday:  Mostly sunny skies, maybe a passing cloud or two, cooler, daytime high struggles to get to 52.


That's a look at your weather for this Monday.  Have a great day!  Blessings.
