We had our first spring thunder yesterday and a tenth of an inch of rain in Otsego. Our high and low temps were 70.9°F / 48.7°F respectively. We currently have 47° at 5:30 this morning.
Average highs for today are in the low to mid-50s and we will exceed those numbers today and tomorrow by 20° – we may close in on 80° today and tomorrow especially in southern Michigan. There are signs our temps will get back down to normal next week.
- Low chances for rain with upper ridging today and tomorrow Showers and thunderstorms currently over Wisconsin should weaken as they move into the shortwave ridging across Lower Michigan, but they could bring clouds and low chance POPs and affect max temperatures. Minor tweaks were made to the grids to account for this but given the nature of the uncertainty with convection, this will continue to be closely monitored. A similar situation will follow for Wednesday as the ridge axis shifts east and heights begin to fall but most of the clouds and rain will be off to our west, closer to the upper low. - Upper low approaches Wednesday Night with Showers and Thunder The best chance for rain will be Wednesday night and Thursday as upper low pushes occluded front through Lower Michigan. Slow moving area of rain and embedded thunder could bring up to an inch of rain by Thursday night. The upper low remains in the area into the weekend with cooler temperatures and periods of showers persisting each day with diurnal enhancement.
