The season’s first powerful winter-like storm is blasting the northern Plains. Minnesota is on the warmer, rainy side of this system.
The National Oceanic and Atmospheric Adminstration’s NAM 3 km resolution model shows bands of rain and embedded thunderstorms rotating around the low-pressure system sweeping through Minnesota through tonight.
The loop below runs between 1 p.m. Wednesday and 1 a.m. Thursday.
The heaviest rainfall with this blustery October system favors western Minnesota which could see an inch of rain. Much of eastern Minnesota will end up closer to one-quarter inch of rainfall with this system. Wind gusts over 40 mph Wednesday are common.
Big temperature contrast
Large temperature contrasts help drive big storms in the Upper Midwest. Check out the temperature differences between Minnesota and the western Dakotas today. Temperatures are in the 30s on the backside of this system, with 60s on the warmer side here in Minnesota.
Heavy snow west
Farther west on the cold side of this storm, nearly 2 feet of snow has fallen in the Black Hills of South Dakota.
Wind gusts have been clocked at 60 to 70 mph in that area:
3 NNW Scenic [Pennington Co, SD] MESONET reports NON-TSTM WND GST of M61 MPH at 11:50 AM MDT --
5 WNW NEW Underwood [Pennington Co, SD] MESONET reports NON-TSTM WND GST of M73 MPH at 11:50 AM MDT --
Minnesota is fortunate to be on the warmer side of this weather system. But the first heavy snow and blizzard warnings of the season in the Black Hills area remind us that wintry weather is not far away.
