.UPDATE...
Issued at 659 PM CST Thu Feb 7 2019
Radar indicated light snow between FAR and GFK and into west central
MN. The snow was moving to the southeast about 15 knots. Tweaked
temps, dewpoints and winds for tonight. Lowest visibilities remain
between FAR and GFK. No other update at this time. Blizzard warning
remains in effect.

.SHORT TERM...(This evening through Friday)
Issued at 307 PM CST Thu Feb 7 2019
Through the afternoon, valley winds have maintained sustained values
in the upper 20s mph with gusts into the 30s and 40s and
widespread valley visibility of a quarter mile or less. As the
departing system builds into the Great Lakes region and surface
high pressure builds into the Dakotas tonight, winds will
gradually weaken. Winds falling under 20 kts by later evening are
expected to lessen coverage of blowing snow, considerably
improving visibility. There may still be patchy blowing snow
lingering overnight but think timing is still on track so will
transition from current snow/blowing snow headlines to wind
chills at 9 PM.
As winds decrease tonight, clouds will lift and begin to scatter out
and colder air builds back into the region. Issuing a Wind Chill
Warning for widespread dangerous -40 to -50F wind chills developing
tonight and into early Friday. With winds weakening and temperatures
rising back into the upper teens and single digits below during the
day Friday, wind chills are expected to remain in wind chill
advisory criteria through the entire day Friday and that night.
Suspect there will need to be a transition from Wind Chill Warning
to Advisory later in Friday morning but will leave that to
subsequent shifts.
.LONG TERM...(Friday night through Thursday)
Issued at 307 PM CST Thu Feb 7 2019
Dangerous wind chills are the main focus each night and morning
from Friday night through the weekend, with wind chills dropping
into the 20 to 40 below range each night.
Models in general agreement this run and will opt for a blended soln
at this time. Sfc high pressure is expected to retreat into the
Great Lakes to start the period. Return flow will help prop up
temperatures for Saturday and Sunday...although values will still
remain below normal. Monday will remain tranquil with below normal
temperatures.
By Tuesday...another wave is forecast to develop over the central
Plains...with an inverted trof extending back into Minnesota and the
Dakotas. Abundant moisture ahead of the system will help produce
measurable precipitation...although amounts are uncertain for now
and will continue to monitor as the event gets closer. As the system
departs early Wednesday...will see another brief drop in
temperatures...and quieter weather to end the period.

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