.SHORT TERM...(This evening through Thursday night)
Issued at 308 PM CDT Wed Oct 21 2020
Coordination with WPC and neighboring NWS offices for the snow
amounts and headlines. 12z model runs continued south trend in
focusing heaviest QPF and snow in far northern SD. Potential for
mixed precipitation also has shifted south out of the fcst area.
Snow will develop east along the SD/ND border tonight, reaching
far southwestern fcst area 06z or so and then spreading east by
09z into west central MN. Snow will also develop northward toward
Valley City, Fargo and Detroit Lakes late tonight. Main
frontogentical forcing is lining up in the 09z-15z period over far
NE SD and holds there. WPC highlights this area for snowfall rates
of 1-2 inch per hour psbl along the ND/SD border. Forcing is much
less north of the SD border and expect a drier north-northeast
wind to keep the main snow at bay and prevent much from getting up
to Highway 2 during the day Thursday. Many models have very little
precipitation into DVL-GFK-TVF and this is reflected in much lower
snowfall potential this region from under an inch to max of 2.
Even this may be high. Snow will end in WC MN Thursday evening.
Blowing snow not an issue as winds not that strong, but some
drifting psbl in heavier snow areas due to north-northeast winds
20 kts or so Thu aftn.
.LONG TERM...(Friday through Wednesday)
Issued at 308 PM CDT Wed Oct 21 2020
Overview...
The primary impacts looking ahead to the extended forecast period
will be another potential winter weather event on Saturday/Sunday
and continued well below normal temperatures, with potential record
breaking minimum low temperatures possible in some areas on
Saturday.
Friday Night through the Weekend...
Generally zonal flow aloft is indicated by ensemble guidance for
Friday through at least the early weekend. By late Saturday, a
shortwave is expected to move through the region and an attendant
upper level trough looks to deepen over the northern Plains. There
is significant disagreement between ensemble products currently on
how this system will evolve, however.
Any lingering snow potential from the Thursday system should taper
off well before Friday evening. The main impact during the overnight
period will be the generally clearing skies. This will lead to
enhanced radiational cooling over much of the forecast area and is
currently expected to drop early Saturday morning low temperatures
into the single digits to low teens. A region of surface high
pressure will try to settle in on Saturday, although the passing
shortwave aloft may still bring some precipitation to the forecast
area. This is where the main discrepancy lies between ensemble
outputs. The GEFS and Canadian ensembles are both trending toward a
solution of generally light snow over the southern half of the CWA,
while the ECMWF is resolving a light snow event across the majority
of the CWA instead. Confidence is currently low with regards to any
one outcome for this system as the model spread is still quite
variable and will continue to be monitored as it moves closer in
range. Precipitation potential aside, with the surface high pressure
and a brisk northerly wind in place for much of the weekend,
subsidence and persistent CAA will keep high temperatures in the 20s
for the weekend.
The Week Ahead...
Following the shortwave passage on Sunday, sky cover is expected to
begin clearing out and there will again be the potential to see
early morning low temperatures on Monday and Tuesday dipping into
the single digits to low teens. Winds should generally be light but
there will still see some potential for wind chills near to even
below zero in some places. Temperatures look to "rebound" up to the
low to mid 30s for some sense of a reprieve on Wednesday. Ensemble
guidance is hinting at a shortwave clipper system that could impact
and bring precipitation to the forecast area on Wednesday as well
but confidence is currently very low.
