MN weather: Warmer and more humid Friday

It's a warmer and more humid Friday ahead of a hot and steamy weekend. FOX 9 meteorologist Cody Matz has the full forecast.

The Brief

    • Friday brings rising humidity and temperatures with highs in the 80s and low 90s.
    • There's a chance of storms overnight, though it will likely stay north of the Twin Cities.
    • The Twin Cities metro is under an excessive heat warning this weekend, with feels-like temperatures in the triple digits.

MINNEAPOLIS (FOX 9) - Heat and humidity start building on Friday ahead of a very hot and steamy weekend. 

Friday’s forecast in Minnesota

What to expect:

Friday is mostly quiet with increasing humidity and occasional sunshine. Winds stay light out of the south at 10-15 mph. 

An extreme heat warning is in effect for southwestern Minnesota, where heat index values will reach the triple digits. The warning will expand to central and southern Minnesota this weekend with temperatures feeling like 100 to 110 degrees. 

Highs on Friday will be in the 80s for much of the state, 90s in southwestern Minnesota, and cooler in the 60s and 70s across the Arrowhead region. The Twin Cities daytime high is around 86 degrees, but it will feel warmer due to rising humidity. 

Thanks to the building heat, overnight lows will remain warm in the upper 70s.

Storm chances:

Several clusters and/or a line of storms are likely to develop Friday night into Saturday, mainly across the northern third of the state. These storms could include gusty winds, large hail and isolated tornadoes.

Much of northern Minnesota faces a level 3 enhanced risk for severe weather, parts of central Minnesota are under a level 2 slight risk, while the metro is under a level 1 marginal risk. Most of the storm activity is expected to stay north of the metro.
