The Twin Cities area can expect a replay of Sunday's bitter windchills on Monday, perhaps not as severe as the 40 below reported Sunday in Lakeville, but potentially dangerous nonetheless, forecasters say.
Windchill readings of 25 below to 35 below are forecast for all of central and southern Minnesota and western Wisconsin under an advisory that is expected to run until noon Monday, the National Weather Service (NWS) said.
The good news, relatively speaking, is that the high temperature could creep above zero to 1 degree in Minneapolis on Monday afternoon, following a frigid Sunday that saw the high hit just 3 below at Minneapolis-St. Paul International Airport.
Cars groaned across the metro and firefighters had to take special precautions while battling blazes in Minneapolis and St. Paul.
In Lakeville, on the windswept southern metro, the windchill reading touched 40 below just before sunrise. As lunchtime neared, there was a bit of warming, with nearly all sectors of the Twin Cities clawing back into single digits below zero, the Weather Service reported.
Vehicle batteries strained to get engines started in the Twin Cities. A spokeswoman for the AAA auto club said its call volume for assistance was 53 percent higher than on a normal winter Sunday, as of early evening.
A slight jump in the number of frostbite cases was detected over the weekend. "A half-dozen or more" new frostbite patients were reported at Hennepin County Medical Center in that time, hospital spokeswoman Christine Hill said.
According to theWeather Service, the windchills being forecast through Monday morning can cause frostbite to exposed skin in as little as 30 minutes.
