Slow-Moving Storm Bringing Beneficial Rains

Southeastern Wisconsin remains in a deficit for rainfall 23 days into May. In fact, every day this month we have been below average for rainfall. Sitting at 1.63” of total rainfall at Mitchell International Airport, we are at 0.72” below the average. With beneficial rainfall in the forecast, we could soon be looking at an average monthly rainfall when all said and done.

A slow-moving low pressure system will usher in a few chances of rainfall today, tonight, and even Wednesday. Strong to severe storms are not expected with the lack of dynamics; a few thunderstorms could contain small hail and brief heavy downpours. The rain, and even downpours, could lead some spots into seeing 0.50”-1.00” of rainfall. This would certainly eat away at our deficit, if not leading to a surplus, for now.

Another round of showers and thunderstorms could pull in by this weekend. The humidity could rise a bit on Saturday with 70s returning to the area as early as Friday. Along a warm front and low pressure system, scattered showers and storms could bring more rain to the area. Let’s see if Mother Nature allows us to return to normal for rainfall by month’s end!
