Brace yourself. A cold front is moving in, and fast.
People in and southeast of the Twin Cities enjoyed highs around 70 degrees Monday and Tuesday. But come Tuesday night, temperatures are expected to dip down into the 40s.
Meanwhile, northern and western parts of the state have already been experiencing those cooler temperatures. The Tuesday night lows for those areas will linger right at or above freezing. There's also a chance of rain.
As for Wednesday, highs for the upper half of the state will be in the mid to low 40s. And highs in the lower half will be mid 40s to low 50s.
Weather Underground says the average high for the Twin Cities on Oct. 12 is 60 degrees, so this is colder than usual for this time of year.
Frost Wednesday night
If you haven't yet, Wednesday might be a good time to cover your plants and turn on the heat because the NWS is expecting frost to cover most of the state Wednesday night.
Forecasts show that pretty much the entire state will see lows between 25 and 33 degrees that night.
But don't worry. It's not all sweater and jacket weather just yet.
Temperatures will start climbing again starting Thursday, and by Saturday the Twin Cities could have a 70 degree high again.
Even though it's not expected to be that cold, Minnesota's Cold Weather Rule starts up on Saturday, Oct. 15.
The rule makes sure people who struggle to pay their bills still have heat during the coldest months.
