Some snow on the way late tonight into Sunday morning

An area of low pressure will move quickly across the Dakotas and Minnesota tonight into Sunday morning, this low will exit to the NE by Sunday afternoon. A brief period of stronger atmospheric lift will accompany this system which should go on to produce an expanding area of precipitation across western and central Minnesota by late tonight.

This will be a quick hitting system, with snow only lasting a few hours at most.

Snow will spread into the Brainerd Lakes area after Midnight tonight, and then will see some snow spread farther ENE Sunday morning. Snow diminishes from W-E by Sunday afternoon.

Note: Some snow is possible in Duluth and Superior ~5 AM to 10 AM Sunday. Total snow accumulations of an inch or two are possible in the Twin Ports.

We could see some bursts of heavier snow thanks to an area of steep mid level lapse rates which will move over the Northland early Sunday morning, but given how quick this system moves through I think it will be difficult to get more than 2 inches of snow out of this system.

There is a chance for some more snow or possibly a wintry mix on Tuesday. At the moment it looks like we could see a widespread swath of about 1 to 3 inches of snow across the Northland on Tuesday, with a chance for some higher amounts. Stay tuned.

Thanks for reading!
