Extreme Cold in North Dakota, December 24 to 26, 2017

Area Forecast Discussion
National Weather Service Grand Forks ND
315 PM CST Sun Dec 24 2017

.SHORT TERM...(This evening through Monday)
Issued at 315 PM CST Sun Dec 24 2017

The few remaining snow showers have slipped into the far southern
Red River Valley and adjacent areas of west central Minnesota.
These should exit off to the southeast in the next few hours,
leaving just a dusting of snow. The rest of the night into Monday
will be very cold, with 5 to 15 mph northwest winds. Therefore
dangerously cold wind chills will become the main issue. Have
issued wind chill warnings and advisories tonight through Monday.

.LONG TERM...(Monday night through Sunday)
Issued at 315 PM CST Sun Dec 24 2017

A broad upper trof will be in place over the area...with the coldest
air in place over Ontario. Northerly flow associated with surface
high pressure will keep the arctic air locked in at least through
Tuesday night...with bitter cold wind chills expected to continue.

By late Wednesday, expect a bit of temperature modification with
moderate ridge amplification over the northern Plains and surface
return flow. Will see chances for precipitation increase as a low
pressure system moves in from the west. Otherwise, another shot of
arctic air is forecast behind the system...with a return to bitter
cold temperatures and wind chill values through the end of the
period.

.AVIATION...(For the 18Z TAFS through 18Z Monday afternoon)
Issued at 1217 PM CST Sun Dec 24 2017

Clouds are going to be the main aviation challenge. Models are
showing a little less cloud cover, so have gone with SCT clouds
for most locations throughout the 24 hour TAF period. Wind speeds
will stay on the lower end.
