'Weather whiplash': Muggy, stormy today; October-like tomorrow


A warm and muggy Tuesday will turn stormy, which will usher in late October-like temperatures across the state for the rest of the week.

Meteorologist Paul Huttner wrote on MPR News' Updraft blog that we're in for "weather whiplash" in the next 24 hours, saying people may be using their air conditioner and furnace between Tuesday and Wednesday afternoon.

Temperatures will near 80 degrees in southern Minnesota Tuesday and dew points in the 60s are expected throughout the state, before a strong storm system rolls in, which is expected to bring widespread rain and the chance of thunderstorms across the state Tuesday night into Wednesday, the National Weather Service says.

Storms are expected after 9 p.m. in the Twin Cities, with rain possible earlier in the evening, the weather service notes. With the storms Tuesday night, there is a slight risk of severe weather, mainly in the southern portion of the state near the Iowa border, the weather service says.

One to 2 inches of rain is possible for much of the state (see map below), which brings a higher risk of flooding in southeast Minnesota, as well as parts of Iowa and Wisconsin. This has prompted the National Weather Service to issue a flash flood watch for those areas.

As storms move out Wednesday, cool air will blow in. Temperatures are expected to be in the 50s for the Twin Cities and high 40s for northern Minnesota (see map below), with lows in the 30s. The average high temperature for this time of year there is in the mid-70s for Minneapolis, the Weather Channel says.

Huttner says "winds will howl like the gales of October" as gusts are expected to reach over 30 mph across the state, with the chance of them approaching 40 to 50 mph on Lake Superior Wednesday.

The October-like weather is expected to hang around through the weekend, KARE 11 says, with the chance of frost likely Saturday morning outside the metro area, meteorologist Paul Douglas wrote on the Star Tribune's weather blog.

Sixty-degree temperatures are expected to return by Sunday, with 70s possible next week for the Twin Cities. Huttner says long-range forecasts show temperatures could reach the 80s again before the end of the month.
