More showers and storms move in Tuesday night

Hot and very humid weather continues

Another round of showers and storms is poised to move across Minnesota, but with less extreme rainfall totals than recent storms. Hot and humid weather carries us well into the start of July.

Both of our past two overnights brought lingering storms which produced areas of record rainfalls and flooding. 

That excessive rainfall threat has ended, but all the moisture led to dew points in the 70s Tuesday and uncomfortably high humidity.

More storms move in

Now, more storms are moving into western Minnesota by late Tuesday night, then spreading across the state Wednesday. The storms will be more widespread Tuesday night, then become spottier during Wednesday as they head east. The storm system may also bring some severe weather to the western edge of the state late Tuesday and isolated strong storms through central Minnesota Wednesday.

Unlike the extreme rainfall Minnesota saw the past two days, these storms are associated with a cold front sweeping across the state which will keep storms moving and minimize any chances for excessive rainfall.  Most rain totals through Wednesday will be under a half inch and even less in most of eastern Minnesota.

After the system moves out late Wednesday, the weather pattern turns quieter, with only spotty chances for showers and storms through Saturday.

An extended period of heat

The cold front and clouds Wednesday only cool temperatures slightly, with highs mostly in the 80s.  By Thursday, under mostly sunny skies, most of the state makes it back into the 90s, then the entire next week remains in the 80s and 90s across most of Minnesota.

Humidity levels also remain high, so the heat index will reach near and possibly surpass 100 degrees at times. Even the overnights remain very mild, with lows in the 60s and 70s.
