Road Conditions

Minnesota – https://lb.511mn.org/


This is quite the cold front for early April! Temperatures this afternoon were only in the teens and 20s across the Dakotas into western Minnesota while 50s and 60s were found ahead of the cold front in eastern Minnesota and Wisconsin. This cold front is moving slowly east and will move through the Northland on Friday.

A slow moving system that’s for sure!

A powerful storm off the northeast US over the Atlantic combined with an upper level ridge between that low to the east and the one to the west is causing our system to move very slowly. Will see the system over the Northern Plains finally pass through the upper Midwest on Friday.

…Weather Summary…

Active weather later tonight and Friday followed by a pleasant weekend.

A sharp cold front over western Minnesota this afternoon moves slowly east, passing through the Northland on Friday. Deep moisture ahead of the front with precipitable water of 0.50 to around 0.90″ coupled with a decent amount of lift associated with the front will cause rain to become more widespread across our area from SW-NE by later tonight.

Precipitation will start as rain with mild boundary layer temps, but colder air moves in immediately behind the cold frontal passage which will cause the rain to change to a few hours of wet snow, sleet and freezing rain. This change-over from rain to frozen precipitation types will move from west to east across the Northland on Friday, starting early in the morning over western areas (Brainerd to I’Falls on west) reaching the Iron Range before Noon Friday, then eastern Minnesota and northwest Wisconsin Friday afternoon-early evening. All of the precipitation ends Friday night.

*Snow accumulations through Friday afternoon – Generally a dusting to around 3 inches with the highest amounts in western-northwest portions of the area.

*Ice accumulations through Friday afternoon of one-tenth to as much as a quarter inch are possible in north-central Minnesota, south to the Brainerd Lakes and Aitkin areas with generally less than one-tenth inch of ice accumulation from the Iron Range to eastern Minnesota.

Lows tonight will vary considerably, ranging from the 20s in far western areas to the 40s in far eastern Minnesota and most of northwest Wisconsin.

Highs Friday will be in the 20s, 30s and 40s, but temperatures which start mild in eastern Minnesota and northwest Wisconsin will be dropping during the afternoon.

South or east winds ahead of a cold front, shifting west-northwest behind the cold front. Wind speeds 10 to 20 mph.

This weekend looks mainly dry as high pressure moves through the area. Highs Saturday will mainly be in the 40s with highs Sunday in the 40s and 50s, cooler along the North Shore.
