954 FXUS63 KOAX 130850 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 350 AM CDT Mon Oct 13 2025 .KEY MESSAGES... - Cooler today and tomorrow with highs in the dipping into the 60s and increasing rain chances this evening into Tuesday. - Warming Wednesday into Thursday with increasingly gusty winds and highs returning to the 70s/80s. - Another cold front sweeps through Friday, bringing in cooler but still comfortable conditions this weekend. && .DISCUSSION... Issued at 346 AM CDT Mon Oct 13 2025 Today and Tomorrow: Water vapor imagery this morning features a quickly-pivoting, negatively-tilting vorticity maximum over Manitoba/Ontario dragging southwesterly mid/upper flow across the central CONUS with another trough digging southward along the Pacific Coast. That aforementioned trough continues to drag cooler air southward across the Northern and Central Plains, with temperatures bottoming out in the 40s to lower 50s and surface moisture being scoured out in tandem this morning. A much cooler day is in store for eastern Nebraska and western Iowa today, with highs topping out in the 60s to a hair above 70 in southeast NE/southwest IA alongside northeasterly winds an increasing cloud cover. Above the surface at 850 mb, south- southeasterly winds are expected to return with the lessening influence of the departing system, spreading warm air advection across much of the Central and Northern Plains. Working against that warm air advection will be a southwesterly jet streak that is set to strengthen with the digging Pacific Coastal trough to the west to bring mid/upper level convergence, hampering the amount of lift above 600 mb. What this should amount to is spotty sprinkles and rain that should begin developing mid-day, spreading northeast from Kansas and western Nebraska. Coverage of what is expected to be light precipitation should gradually increase over the course of the day, but particularly overnight before peaking late Tuesday morning/midday. Most of the area is currently forecast to receive 0.05-0.15" of rain through Tuesday, which is better than we`ve seen over the past week but not much in the grand scheme of things. Forecast soundings depict MUCAPE limited to less than 50 J/jg, but that could be enough to give us a rumble of thunder or two over the course of the day. Expect a gloomy Tuesday with even cooler highs in the upper 50s to 60s, a hair under normal for this time of year and another thing pointing out how abnormally warm October has been so far. Wednesday and Beyond: Our breath of crisp fall air won`t last too long, as a quick warming trend sets in for the mid-to-late work week, as the upper pattern sees the aforementioned coastal trough bottom out and begin pushing through the Interior West, building up a ridge to its immediate east. Highs hit the 70s area-wide Wednesday with 80s returning to all but northeast Nebraska on a windy Thursday, with only low-end chances for rain as a few mid/upper impulses are shot out through the flow. Late Thursday into Friday, that trough is then expected to eject across the Central and Northern Plains, dragging another cold front and associated baroclinic zone through the area. With the overall system ejecting north of the area, we`ll find less efficient moisture return ahead of the cold front further complicated by daytime mixing to limit the instability available for storms in addition to any rainfall, with extended-range ML guidance signaling little severe threat associated with its passage. Once the cold front pushes through, the main mid/upper trough will deepen over the central CONUS and push us back down into the low 70s/60s for highs this weekend, which should make for an above-normal but nice weekend to spend outside doing fall activities. && .AVIATION /06Z TAFS THROUGH 06Z TUESDAY/... Issued at 1059 PM CDT Sun Oct 12 2025 VFR conditions are expected to prevail through the forecast period. Northerly winds will continue at 12 kts, gusting up to 20 kts before calming under 12 kts by 07-08Z. A few isolated showers are possible overnight (15% chance). This potential has not been included in the TAFs at this time due to the low confidence in shower coverage. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None.
