Happy Memorial Day, and thanks to those of you that are serving, and have served, both here and abroad, alive or no longer with us. Thanks for safeguarding our freedom and this nation!
Summer is here, at least in the minds of most, with Memorial Day through Labor Day being defined as summer. And it will feel and act like it too! It will be hot and muggy, scattered showers and thunderstorms are on tap for the afternoon and evening, some of those could be severe. Let's take a look and see what's going on.
TEMPERATURES: Very warm. Jackson is already into the 70's, with Lansing almost there, and it is not even 8AM as I write this forecast! Here's a look at temperatures around the country at 8AM...You can see the big warm air ridge east, and the cold trough west. The 50's and 60's readings show you where the cold front is now that we expect to roll through here in the next day or two...
I expect the high for Jackson today to get to 92, with 91 in Lansing, but heat index values will be in the upper 90's, possibly even 100. Tomorrow, about a 10 degree drop, and after that, another 10-15 degrees falls off, with daytime highs rolling back into the mid to upper SIXTIES. Average temperatures this time of year run around 75 for this area, and all signs indicate we'll be below that, as a cold front moves through, bringing precipitation along with it. Let's look at that part.
RAIN: A much wetter look than we have seen in recent days, with Michigan looking at a range of over two and-a-half inches to about a half-inch from east to west for the next five days. Here's the forecast map from the National Weather Service, valid at 7AM today...
A cold front pushes through later today and into tomorrow, kicking off showers and storms, then we stay fairly dry until another trough drops in here on Friday, bringing us a wet weekend from the looks of things.
SEVERE WEATHER: The Storm Prediction Center has us under a "slight" risk for severe weather today. The main issues would be hail and damaging wind. After we get through today, no sever weather is expected in Michigan for the next couple of days after that. Here's the map for today from the SPC, valid at 7AM...
As you see, the other potential hot spots are in lower New England, and a chunk of north central Texas, and south central Oklahoma.
Nothing on the Grand Rapids NEXRAD radar at this hour but ground clutter, I do want you to notice the green numbers on the observations.
Those are dewpoints. All of them in the 60's and it's just now after 8AM. The only non 60 reading is way up north at the top in Alpena, with a 55, but that's also their air temperature, so the humidity is 100%! The sun is risen enough to see and use the visible satellite image, that shows some scattered clouds...
Currently Jackson is 72 with a dewpoint of 63, relative humidity a sticky 68%, winds SW at 7 MPH.
Here's the Memorial Day forecast for Jackson and surrounding communities including Concord and Pleasant Lake...
Today, mostly sunny, clouds increase as the day wears on, with a chance at scattered showers and thunderstorms, some possibly severe. Hot, humid, high 92, heat index values near 100. SW winds 7-15 MPH.
Tonight cloudy, still a chance at scattered showers and thunderstorms, some may be severe, nighttime lows roll back to 66, SW winds 5-10 MPH.
Tuesday, a mix of clouds and sunshine, cooler, chance at a widely scattered shower or two on the back side of the cold front moving through, high 81, winds SW 7-14 MPH.
Tuesday night, clear skies, much cooler, lows drop to 50, WNW winds 6-12 MPH.
Wednesday, mainly sunny with a few passing clouds, unseasonably cool, high only 66.
Thursday, sunny, continued cool, high 67.
Friday, cloudy, with a chance of scattered showers, high 68.
Saturday, continued cloudy, still a chance of scattered showers, high 67.
There's a look at your forecast for the next six days, I do hope you have a safe and enjoyable Memorial Day! Blessings.
