169 FXUS63 KOAX 222002 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 202 PM CST Fri Nov 22 2024 .KEY MESSAGES... - Above normal temperatures and dry conditions through the weekend. - A cold front Sunday afternoon will begin to usher in another polar airmass to the region, dropping high temps below normal for next week into the 30s and lows into the 10s/low 20s. - Small chance (20-30%) of rain and snow next Wednesday, but little or no impacts expected. && .DISCUSSION... Issued at 200 PM CST Fri Nov 22 2024 Quiet weather continues into the weekend with a warming trend expected, as an upper level ridge remains in place across the Midwest. High temperatures are forecast to climb into the upper 40 to upper 50s for Saturday, with mostly sunny skies. And similar high temperatures are forecast for Sunday ahead of a cold front. This frontal boundary will begin to usher in much colder, below normal temperatures for next week. Some of the models suggest that there could be a small chance of flurries or snow showers Sunday night into Monday as the colder air moves in behind the frontal boundary, but NBM remains dry. Will keep Pops out of the forecast at this time, but keeping an eye on trends and wouldn`t be surprised if we eventually need to add at least slight chance pops during that time. If any precipitation does occur, it shouldn`t have a significant impact. Looking farther ahead in the forecast to the middle of next week, there`s good agreement among models that another upper level wave will be moving out of the Rockies. Operational runs of the GFS/ECWMF/CMC seem to be trending farther south, but NBM, which includes all flavors of the ensembles, still suggests small 20-30% precip chances extend northward to the I80 corridor Wednesday into early Thursday. And this would be a rain/snow mix. Given the southward trends of the models, it`s looking like better chances for any accumulation would be occurring across KS/MO at this time, with little or no impacts in our area. Again, will keep en eye on model trends over the next couple of days, considering the expected increased travel leading into the Thanksgiving holiday. Looking farther ahead in the 6-14 day period, CPC continues to call for below normal temperatures and an above normal chance of precipitation. && .AVIATION /18Z TAFS THROUGH 18Z SATURDAY/...
