Snow along I-90 corridor Thursday into Friday
A winter weather advisory goes into effect in southern Minnesota at 6 p.m. Thursday through the early morning Friday in southwest Minnesota and through mid afternoon Friday in southeast Minnesota where the snow will end later.
The precipitation will start as snow and even some freezing light rain in southwestern Minnesota Thursday evening and spread north and east into the night through Friday morning. The Twin Cities will be on the northern edge of this precipitation.
Parts of southern Minnesota along Interstate 90 could see snowfall of up to 5 to 6 inches. In the Twin Cities most totals will be under 1 inch, though some southern suburbs could see around an inch.
After the snow, it’ll be a mild weekend with highs in the 30s, nearly statewide. That mild air sticks around into next week which will play into our next, larger storm system.
Large, slow moving storm next week
A large storm system develops early next week and will become what we call a cut-off upper-level low, which means it’s cut off from the main flow of the atmosphere and is stuck between the jet streams.
It’s still early to get into details, but at this point the areas most favored for heavy snow is western and northern Minnesota back into the Dakotas. There will be a lot of warm air drawn into this system which means we will likely be talking all forms of precipitation for Minnesota.
