Light Showers, Cooler Temperatures...

Good Morning!


What a FANTASTIC weekend was it not?  Warm and rain-free, any outdoor activity was possible, and sunscreen, bug repellent and a cold drink were the finishing touches.  I sure hope you had a chance to get out and enjoy some of it.  The warm summer-like weekend is behind us now, and as we head back to work today, cooler temperatures settle in with us through Wednesday, then the warmth comes back, with the thermometers again eyeballing 90.  One deeper dive coming up...


TEMPERATURES:  In the blog area, three records fell, two more were tied yesterday as temperatures throughout South Central Michigan were well into the 80's.  Out in west Michigan, a couple of 90 degree readings were posted.  We'll be 10-15 degrees cooler today across most parts of the blog, as a shortwave trough tracks across the area, pulling down a bit of cooler air from Canada along with it.  We stay in the 70's until ridging with warm air under it pushes back in, sending readings back into the mid to upper 80's for Thursday, then a slight moderation in temperature puts us in the 76-83 range for the rest of the week.


RAIN:  Pretty quiet overall, with just a a few showers showing on radar.  Not a ton of heating around to provide enough instability for anything significant right now, even though we have decently moist air, with dew points in the mid to upper 50's or better.  Here's a look at the Grand Rapids NEXRAD radar image...




This is what the National Weather Service says about rain for the next five days. Heavier rainfall expected in the Pacific Northwest, the US/Canada border above Minnesota, and offshore of Florida.  Here in southern Lower Michigan, no more than a quarter-inch is expected between now and 8AM EDT on Friday...




The next quality chance for rain in this part of the world looks to be late Friday night into early Saturday, and this far in advance, modeling is suggesting a scattered shower with a possible roaming storm affair, as opposed to anything more organized.


SEVERE WEATHER:  Once we get past the "general" thunderstorm risk today, nothing for the three day window according to the Storm Prediction Center.  The only reason we even have the general risk today is mainly for thunderstorms forming out in front of this slow moving cold front this afternoon and into tonight.  Here's a look at the Day 1 map, valid today at 8AM EDT:




Here's a look at the visible satellite image, with the NEXRAD radar composite overlaid on it...just a line of light showers on the move...




Here's the local forecast for Jackson and surrounding communities including Rives Junction and Summit Township:


For today, mostly cloudy skies with a peek of sun here or there, just the chance of an isolated or widely scattered shower, cooler with a high of 73, winds swing from SSW to NW 8-14 MPH.


Tonight, a mixture of clouds and stars, cooler, low 47, northerly winds rolling back to 5-8 MPH.


Tuesday, periods of clouds and sunshine, pleasant, high 73, winds N 5-10 MPH.


Tuesday night, mostly starry skies with a passing cloud or two, low 49, winds NE 3-8 MPH.


Wednesday, sunny, seasonable, nice, high 79.


Thursday, sunny, warmer as southwesterly winds return, high 86.


Friday, increasing clouds, not quite as warm, high 83.


Saturday, mostly cloudy, a chance of scattered showers, high 78.


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