KOAX issues Area Forecast Discussion (AFD) valid 2019-12-09T11:13:00Z 031 FXUS63 KOAX 091113 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 513 AM CST Mon Dec 9 2019 ...Updated Aviation Forecast Discussion... .DISCUSSION... Issued at 321 AM CST Mon Dec 9 2019 Today: Primary forecast concern in the near short term are wind gusts behind the cold front that will pass through the area this morning. A wind advisory has been issued for most of the area til noon as sustained winds are expected from the northwest at 20 to 35 mph with gusts up to 45 mph. Though the advisory ends at noon, the winds will still be breezy for most of the day. Wind speeds should begin to noticeably drop by 6 pm. Subsequently, the winds will lead to wind chills around 10 degrees below 0 in areas near Norfolk, Wayne, Neligh, and Crofton. Light snowfall is expected this morning, but totals will not be more than an inch. Snowfall should end by 10 am. Cold air advection behind the front is expected to drop temperatures throughout the day. Temperatures this afternoon should be in the mid teens in far northeastern Nebraska and the mid 20s in southeast Nebraska and southwest Iowa. Additionally, a special weather statement was issued for fog in southeast Nebraska and southwest Iowa. The fog will not be widespread and will be erased by the dry air associated with the cold front. Tuesday and Wednesday: The work week should mostly be uneventful weather wise. The trough over the Hudson Bay will keep the area in northwest flow Tuesday and Wednesday. Temperatures will bottom Tuesday night into Wednesday morning with lows expected to drop below 20 degrees for the entire forecast area. Temperatures will be slightly higher Wednesday as the upper level pattern becomes more zonal and flow at the 850 mb level becomes southerly. Thursday through Sunday: Warm air advection Thursday and Friday will lead to quite pleasant days for mid-December, particularly if winter isn't your thing. Extended range models (GFS and ECWMF) hint at active weather for weekend. As per usual, there isn't much for agreement. However, the systems do not have much amplification and it's likely that any precipitation would be on the lighter side or any lowering of temperatures would be modest. && .AVIATION...(For the 12Z TAFS through 12Z Tuesday morning) Issued at 513 AM CST Mon Dec 9 2019 A strong cold front is in the process of moving through the area with northwest winds of 20-30 kt in its wake. Additionally, post- frontal IFR/LIFR stratus are being observed which should persist through mid morning. A band of light snow stretching from KBVN- KOFK-KLCG as of 5 AM will continue east/southeast, eventually impacting KOMA and KLNK within the next couple of hours. Visibilities will drop to 1-2 sm within the snow band. We expect prevailing VFR conditions by late morning or early afternoon with decreasing winds this evening. && .OAX WATCHES/WARNINGS/ADVISORIES...
