.DISCUSSION...(This evening through Saturday)
Issued at 302 PM CST Sun Feb 28 2021

A clipper will bring very light snow to a portion of the Northland
tonight, then a dry pattern Monday afternoon through Saturday, with
above normal temps.

An Alberta Clipper will move past a portion the Northland tonight.
The surface low will move through the Dakotas and into Iowa tonight.
It will be accompanied by a vigorous piece of short wave energy
moving through Minnesota in the fast northwest flow aloft. This
combination will bring some light snow initially from Cass Lake to
the Brainerd Lakes region this evening. Even though there is plenty
of forcing, moisture will be limited. The clipper will be an
efficient snow producer with a quick half inch to around one inch of
snow around the Brainerd Lakes, lighter amounts east. After the
clipper departs late tonight, a round of lake effect snow showers is
possible over the higher terrain of Iron County. Cold air advection
and a favorable fetch will bring a quick couple tenths of an inch of
snow, before ending as the flow turns westerly Monday morning.

A quasi-zonal flow sets up Monday night and Tuesday with high
pressure at the surface. An area of low pressure will move through
northwest Ontario Tuesday and into the eastern Great Lakes Tuesday
night. A dry cold front will move through the Northland as a result.
High pressure returns for Wednesday through Saturday under northwest
flow aloft. Coolest temps will be Friday night through Saturday
morning with 850mb temps dropping into the teens below zero, before
warming in the afternoon.

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)

Light snow should arrive at BRD between 05Z-11Z, then cigs improve

in the vicinity of HYR from 07Z-09Z in association with the
