Warm Monday followed by thunderstorms into Tuesday

Warm July days will continue on Monday. Afternoon high temperatures will be mainly in the 80s but there will be cooler 70s in the northwest corner and near Lake Superior.

The Twin Cities should warm to about 88 degrees with increasing southeast wind and dew points slowly climbing.

Thunderstorms

Yes, there will be thunderstorms. The first outbreak will be strong thunderstorms in northwestern Minnesota Monday afternoon as a cold front reaches Minnesota from the west.

The weather pattern will become more complicated Monday evening and through the nighttime hours as thunderstorms build southeastward along the cold front as it crosses the state.

Meanwhile, other storms will build in response to an upper-level disturbance from the southwest. Add it all up and it means that showers and thunderstorms will be numerous across Minnesota from Monday evening through the overnight.

Severe storms?

Yes, severe storms are possible. The convective outlook for Monday through Monday night puts most of Minnesota in the slight risk category where scattered severe storms are possible. Southeastern and northeastern portions of the state are in a marginal risk where isolated severe storms are possible.

Heavy rain possible

While parts of Minnesota remain on the dry side and could use some rain, it is possible that repeated training storms could produce flash flooding in some spots.

Tuesday wet and cooler

Cooler weather will build in behind the cold front for Tuesday. Showers and some thunderstorms will linger, particularly over southeastern Minnesota and across Wisconsin.

Pleasant midweek

Comfortable July temperatures with low humidity and generally dry skies will be on tap for Wednesday and Thursday.

Then heat, humidity and unsettled weather will return from Friday into the weekend.
