Severe, isolated thunderstorms possible Memorial Day and Tuesday

severe 1

Warm, humid, and a bit stormy. It won't be a complete washout either day, but Monday and Tuesday both have a risk for severe storms.

A warm and humid air mass has parked itself over the upper Midwest through the Memorial Day weekend. The atmospheric temperature profile favors a few thunderstorms which could produce large hail and stronger wind gusts.

Memorial Day will be warm and humid with highs near 80 and dew points in the low to mid 60's. It will feel like it's in the mid 80's by late afternoon, with or without the thunderstorms.

The first round of showers and storms are possible through the midday hours, likely clearing prior to 4 pm. Then, some clearing will lead to sunshine and increased instability for the second wave after 9 pm.

The Storm Prediction Center has the Chippewa Valley in a Marginal, Level 1, risk for severe weather both Monday and Tuesday. This means an isolated storm or two could become severe. Again, the main threats being large hail and strong, gusty winds.

Tuesday will be identical to Monday, but with multiple waves of scattered thunderstorms. Storms are likely at any time, but not everyone will see thunderstorms at the same time.

The second half of the week we'll see a slow decline in humidity and warmer temperatures. A cooler, more comfortable weather pattern sets up for the last weekend of May.
