Chances of storms

The cold front that triggered scattered strong to severe thunderstorms across northern Minnesota on Tuesday has sagged southward. Expect a similar scattering of thunderstorms Wednesday afternoon and evening across central Minnesota. Some storms could become strong. Isolated severe storms will be possible, including in and near the Twin Cities. The dark green is a marginal risk (level 1 of 5) of severe weather from northeastern South Dakota to Upper Michigan.

While some storms might linger into early Thursday, most of the day will be pleasant.

Better chances of rain Thursday night

A stronger atmospheric ripple will bring a better chance of showers and storms Thursday night and again with the heating of Friday. August rains tend not to be very reliable and can’t be trusted to break a drought.
