Area Forecast Discussion
National Weather Service Grand Forks ND
533 AM CST Sat Mar 2 2019

.SHORT TERM...(Today and tonight)
Issued at 320 AM CST Sat Mar 2 2019

Impacts will revolve around dangerous wind chills. Cold airmass
will continue to gradually filter into the region today/tonight.
Current satellite imagery indicates cloud cover and observations
indicate flurries along and behind the leading edge of this
airmass. Flurries extend upstream into Canada, so did adjust Wx
grids to include flurries for much of the day. By this evening, 
wind chill values will be around -40F, and thus issued a wind
chill warning. 

.LONG TERM...(Sunday through Friday)
Issued at 320 AM CST Sat Mar 2 2019

Impacts during this forecast period revolve around blowing snow 
potential Sun/Mon and wind-chill inducing perennial arctic cold. 
Pronounced daytime adiabatic mixing and potential for momentum 
transfer could lead to patchy, if not areas of blowing snow. On 
Mon a clipper or two rounding western edge of Hudson Bay low could
add some falling flurries or snow showers to the package. A more 
westerly wind direction will favor a Devils Lake to Valley City 
tract for blowing snow, with much less effect along the valley 
proper. 

The sub zero cold combined with at least modest wind speeds will 
keep wind chill headlines in the picture for Sun night. Some 
moderation will most likely obviate the need for these after that. 
below average temps will naturally continue for the upcoming week and 
a late week system could increase snow chances as we approach the 
weekend. The early guess at this would aim at the southern forecast 
for potential impact.

.AVIATION...(For the 12Z TAFS through 12Z Sunday morning)
Issued at 533 AM CST Sat Mar 2 2019

Look for mostly VFR conditions. Most of the region will have VFR 
clouds (3500-8000 ft cigs) and flurries, although occasional MVFR
cigs/vsby are possible. Winds will be northwest 10-20 mph.
