.UPDATE...

Areas of stratocu dissipating in most areas leaving a mostly clear
sky attm. Upstream clouds should move into the DVL basin
overnight. Overall fcst in fine shape and few changes.

.SHORT TERM...(This evening through Saturday)
Issued at 320 PM CST Fri Feb 24 2017

Mid level split flow and surface high pressure ridge break down
leaving broad nw flow aloft and a series of weak impulses
dropping through the FA next few days with minimal impacts.

Any clearing tonight should be brief as clouds move in ahead of
next weak wave. Temperatures tonight will be dependent of degree
of cloud cover but overall looking at temperatures close to
seasonal averages.

All guidance brings in the potential for some light snow with wave
tomorrow. Forcing looks weak so any accumulations should be in
inch or less. Thermal profiles do not change much through the
period so temperatures should be close to average values.

.LONG TERM...(Saturday night through Friday)
Issued at 320 PM CST Fri Feb 24 2017

low aloft remains relatively progressive. Series of short wave
forecast to move across the Red River Valley through the period.
Short wave trough will across the area Sat night/Sun morning and
produce light snow mainly in the southern Red River Valley. Most
places will get an inch or less of snow. Another reinforcing shot of
cold air will move into the region Sun morning.

Flat upper level ridge will move over the area Sun night and another
trough will move across southern Canada Mon. Cooler air will move in
to the area Mon. Very light snow/flurries are expected mainly over
northwest MN Mon.

Flow aloft becomes split with a short wave moving through the
southern stream Mon night/Tue morning. Another trough moves through
Tue night/Wed morning with some light snow.

Another short wave to move through Wed night/Thu morning with
another threat of light snow. The GFS is a faster solution than the
ECMWF.

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