Area Forecast Discussion National Weather Service Grand Forks ND 335 PM CST Sat Jan 18 2020

SHORT TERM. (This afternoon through Sunday night) Issued at 335 PM CST Sat Jan 18 2020

Ground Blizzard conditions ongoing across open country outside of our larger cities in the Red River Valley into the Devils Lake Basin. Strong surge of winds aloft is likely transitions over our area now and as mixing heights decrease so should peak gusts/sustained winds. There may be lingering gusts in the 30-40 mph range after 6PM, so we can't completely rule out visibility impacts, but widespread Blizzard impacts (1/4 mile or less) should be diminished greatly. If vis 1 mile or less lingers long enough consideration may be given to issuing a Winter Weather Advisory once the Blizzard Warning expires.

Regarding Winter Storm Warning: main impacts now are reduced visibilities in open country in blowing snow that is occasionally enhanced by lingering light snow. Snow should continue to decrease in coverage through the evening and winds will drop much faster in our east. The Warning is being held more at this point for the reduced visibility impacts through 6PM.

Wind chills -25 or lower are already being reported in our west where CAA has bring sub zero temps. Winds decrease this evening but temperatures will continue to fall and this will allow for lower wind chills to spread east and south across our CWA. Stratus may limit cooling in our northeast where flurries/or very light snow may linger. A Wind Chill Advisory has been issued for this evening through midday Sunday when improvement is expected. An additional Wind Chill Advisory may need to be considered Sunday night as temperatures will be much colder across our entire CWA (winds may be much lighter though).

LONG TERM. (Monday through Saturday) Issued at 324 PM CST Sat Jan 18 2020

Overall low impacts are expected in the long term period.

Mon - Wed . The long term period begins with a departing 1045 mb high just over eastern SD, which will sink to the south over srn IA/nrn MO by 12Z Wed. An amplifying H500 ridge sets up over the Rockies early in the period, shifting over the northern tier by Wed morning. This will keep the Mon - Wed timeframe dry with warming temps as the sfc high translates SW and return flow sets up into the eastern Dakotas. Expecting a cool Monday followed by Tue-Wed temps rising into the mid to upper twenties.

Thu - Sat . mean H500 ridge breaks down with an upper trough moving across the northern tier on Thu night. Ensemble QPF shows a weak signal for increased moisture but latest model blends keep moisture generally over Minnesota, with low chances of precipitation across the south and east. Low confidence at this point as a cold front moves across early Thu, and coupled with an approaching upper wave, would expect some light snow at minimum. Cooler, but not significantly colder, temperatures follow keeping the end of the week into the weekend highs generally in the low 20s.

AVIATION. (For the 18Z TAFS through 18Z Sunday afternoon) Issued at 1123 AM CST Sat Jan 18 2020

Treacherous flying conditions associated with blizzard in the Red River Valley and DVL . still IFR vsbys/cigs at TVF/BJI (in winter storm warning). LIFR/VLIFR vsbys expected throughout the afternoon, in addition to strong NW winds. Winds subside and vsbys improve aft 00Z, with MVFR cigs beginning to improve aft 06Z. Expect impacts on not only GA but also large a/c due to the low vsbys/RVRs.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
