I am closely watching for development of a big batch of severe storms in Wisconsin this evening that could reach southeast Michigan late at night or during the morning rush hour.
As of the time I am writing this (5:45 p.m.), no storms exist. This particular type of storm is special (it even has a name -- Mesoscale Convective System, or MCS), because it blows up at night and weakens during the day. Since it doesn't exist yet, I can only project what the computer models suggest, which is late-night timing and a highest risk across the southwestern part of our area (Lenawee, Monroe and Washtenaw counties).
Some models bring it farther north, and some take it farther south -- so those of us south of M-59 all need to be aware. I'll tweet any updates this evening at @PaulGrossLocal4 if I can fine tune this forecast any better.
After any early morning storms move out, some sunshine could develop. Then, scattered strong storms are possible once again by mid-to-late afternoon as a cold front swings through. Highs in the upper 70s to near 80. Southwest wind at 8 to 13 mph.
Partly cloudy Wednesday night, with lows in the mid 50s.
Thursday and Friday forecast:
Becoming partly cloudy both Thursday and Friday, with highs in the mid to upper 60s, and overnight lows in the upper 40s.
Then, here we go with the start of an awesome holiday weekend! Look for a ton of sun on Saturday, with highs in the low 70s. Clear Saturday night, with lows in the low 50s.
Sunday will indeed be a “sun-day,” with highs in the mid 70s. Clear Sunday night, with lows in the mid 50s.
Memorial Day is still not a slam dunk but, after a good long look at the afternoon computer models, I'm sticking with yesterday's reasoning: the upper level ridge of high pressure that will dominate during the weekend should remain close enough to squash any thunderstorm development.
So right now, expect a partly cloudy day, with highs near 80! Remember to fly your flag as we honor those who made the ultimate sacrifice for our country. If you don't have a flag, think about going out and buying one -- they're not that expensive.
Let's drape the area with a red, white and blue tribute to our fallen soldiers. I'll proudly fly my flag on Memorial Day. In fact, I just may have it out all weekend since it's not going to rain.
