633 FXUS63 KOAX 201922 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 122 PM CST Thu Nov 20 2025 .KEY MESSAGES... - Areas of fog redeveloping tonight. - Rain chances increasing to 40-80% late tonight and Friday south of I-80. - Mild, dry weather returns over the weekend with increasing rain chances (40-70%) Monday. - Temperatures trending cooler next week with highs in the 30s forecast for Thanksgiving. && .DISCUSSION... Issued at 122 PM CST Thu Nov 20 2025 Tonight and Friday: A negatively tilted short-wave trough over the southern Rockies this afternoon is forecast to weaken as it progresses northeast into an increasingly confluent mid-level flow pattern in place from the central Plains into mid-MS Valley. At the surface, an associated area of low pressure over the eastern TX panhandle into western OK will develop into southeast KS by Friday morning before accelerating east through southern MO. A weak boundary which moved into our area last night will shift into KS and MO, where it will link with the migratory surface low. A relatively moist, low-level air mass present both ahead of and behind the weak boundary contributed to considerable fog development earlier today with visibilities gradually improving as of early afternoon. Associated cloud cover remains fairly widespread with today`s high temperatures adjusted lower to account for it`s presence. A slightly drier air mass will work its way into the northern part of our area tonight with fog development/continuation most likely along and south of I-80. Late tonight into Friday, strengthening low/mid-level frontogenetical forcing ahead of the approaching short-wave trough will support increasing rain chances (maximum PoPs of 40-80%) for locations south of I-80. Most of the precipitation will be light, but some 0.25-0.50" totals are possible near the KS border. Widespread clouds and areas of rain will limit daytime heating Friday with highs in the 40s. This Weekend: Another mid/upper-level low is projected to move into Baja and the Desert Southwest Saturday before shifting northeast into the central and southern Rockies Sunday. Some amplification of a downstream ridge over the central Plains is forecast with southerly surface winds drawing a warmer air mass into the region with highs in the 50s to low 60s. Next Week: The Rockies system mentioned above is forecast to shift into the central Plains Monday with PoPs increasing to 40-70%. A higher- latitude short-wave trough is expected amplify on the immediate heels of the lead system across the northern and central Plains Monday night into Tuesday, supporting the movement of a stronger cold front through the area at that time. Highs mainly in the 50s Monday are forecast to fall into the 40s and 50s Tuesday, 30s and 40s Wednesday, with 30s expected on Thanksgiving. && .AVIATION /18Z TAFS THROUGH 18Z FRIDAY/... Issued at 1115 AM CST Thu Nov 20 2025 Fog and LIFR ceilings have become more widespread and lasted longer than earlier model forecasts. However, latest model data have adjusted to these observations, and have trended in a much more pessimistic direction with respect to visibilities, and moreso, ceiling heights for the remainder of today through tonight. It does appear that a period of VFR conditions are possible at KOFK late this afternoon into early evening. Otherwise, the model data suggest that LIFR conditions will likely continue into Friday morning. The chance of light rain will increase toward the end of the forecast period at KLNK. Winds will continue from the north or northeast at less than 12 kt. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None. IA...None. && $$ DISCUSSION...Mead AVIATION...Mead

120 FXUS63 KGID 202117 AFDGID Area Forecast Discussion National Weather Service Hastings NE 317 PM CST Thu Nov 20 2025 .KEY MESSAGES... - Another round of patchy dense fog possible after midnight tonight. The focus of this fog should be across our south central Nebraska counties. - The first significant rainfall event since late October will spread north across the local area this evening/overnight. Most areas will see some rainfall, but the focus will be south of I-80 with the highest totals anticipated across north central Kansas. - Fantastic late fall weather anticipated for this weekend with highs in the 60s, light winds, and mostly sunny skies (especially Saturday). - The next system will bring a chance of precip back to the area Sunday evening through Monday, with the beginning of a prolonged period of below normal temperatures starting Thanksgiving eve. && .DISCUSSION... Issued at 235 PM CST Thu Nov 20 2025 Another cloudy, cool day across much of the local area where persistent low level cloud cover has helped keep temperatures down several degrees from the previous forecast. While the extent of the remaining low level cloud cover is being partially obscured by high level clouds approaching from the southwest, the edges of what can be seen on satellite are steadily eroding, which should allow most areas to warm a few more degrees. Once the sun angle goes down, however, expect this low level stratus to once again expand in coverage across the local area with some patchy dense fog becoming possible once again late in the night. Latest HRRR is once again indicating the potential for some dense fog across the local area...primarily focused across our Nebraska counties...and added similar wording to the afternoon HWO. For tonight...already seeing some upper level cloud cover spreading across the local area ahead of the main upper level low across the southern Rockies. Expect this low to lift northeast over the next 12-24 hours, gradually spreading precipitation chances across the local area. While the focus of this system has slipped just a bit south from what models were advertising yesterday, much of the local area will likely get some measurable rainfall over the next 24 hours, with the focus remaining across north central Kansas. Further north towards I-80, expect a tight gradient in precipitation chances, with precip totals more likely in the 0.1-0.25 inch range near the Interstate...to over an inch across our Kansas counties. If this materializes as expected, this will be the most significant rainfall in almost a month across much of the area! In addition to the cloud cover, rain, and potential fog for Friday, expect a cooler afternoon with high temperatures in the lower to mid-40s for most. This cool down will be short lived, however, as heights aloft rise over the weekend and mostly sunny skies return, allowing for temperatures to climb back above normal...making for a very nice late fall weekend. Late in the weekend, expect the next upper level low coming out of the southwest to start spreading some cloud cover across the area Sunday afternoon, with another chance for some light rainfall returning Sunday night through Monday. If anything, this system has continued to track just a bit further north, meaning while nearly all of the area will see some rainfall, the most favored areas will be across our south and east. After this next system exits the area Monday, expect an overall pattern change with the northern jet dominating and a northwesterly cool (and occasionally unsettled) pattern setting up across the plains for potentially an extended period of time. Still not a sure thing, but a good number of ensemble members are hinting at the potential for some snowfall as early as Thanksgiving day, but more likely later over next weekend. && .AVIATION /18Z TAFS THROUGH 18Z FRIDAY/... Issued at 1115 AM CST Thu Nov 20 2025 For KGRI/KEAR Airports: Generally poor conditions...with LIFR CIGS/MVFR VSBYS will persist for another couple of hours before LIFR CIGS scatter out and a few hours of VFR conditions (with lots of high level clouds) returns around 20/21Z. CIGS will again thicken up this evening as a disturbance approaches from the southwest, with MVFR CIGS returning by 21/03Z...with some light rain and reduced VSBYS becoming possible around daybreak. && .GID WATCHES/WARNINGS/ADVISORIES...
