513 FXUS63 KFGF 021133 AFDFGF 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. && .FGF WATCHES/WARNINGS/ADVISORIES...
