WEST MICHIGAN — Temperatures will heat up this afternoon with a dry airmass in place and south to southeasterly winds developing behind a departing area of high pressure. This is the way the surface set-up looks as of this writing:
Notice the more humid air building in the Plains states to our west ahead of an approaching warm front. We’ll begin to feel this humidity this evening, and especially tomorrow. With this warm and humid airmass in place tomorrow and that cold front approaching, afternoon showers and storms are possible. In fact, the Storm Prediction Center in Norman, OK has most of West Michigan in a marginal risk for severe thunderstorms:
Even though it looks like the majority of the severe thunderstorms will occur in the slight risk area just to our east, one or two storms could still approach low-end severe criteria. High winds look to be the main threat:
That cold front will pass to our east on Sunday night, with less humid air behind it for Monday. Temperatures, however, will still be on the warm side of average with highs in the lower to middle 80s. A second cold front will push through Monday evening. Behind this front, we expect significant cooling to take place on Tuesday and Wednesday. In fact, some spots could see lows in the 40s by Wednesday morning.
