FXUS63 KOAX 271031 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 531 AM CDT Mon Oct 27 2025 .KEY MESSAGES... - Widespread rain chances (60-85%) return tonight into Tuesday. Rainfall totals of 0.25 to 0.75 inches are expected for most. - Tuesday will be cool and breezy, with northwesterly wind gusts up to 30-35 mph. - Portions of the area may experience freezing temperatures Thursday, Friday and Saturday mornings. && .DISCUSSION... Issued at 152 AM CDT Mon Oct 27 2025 Today and Tomorrow... The closed mid- to upper-level low that has been slowly tracking across the southern Plains over the weekend has shifted into MO/AR. While this feature has had limited impacts on the local area, it has contributed to the persistent low-level cloud cover observed over the past several days. Lingering cloud cover this morning has provided enough insulation to keep low temperatures in the upper 40s to low 50s. Fog has once again developed early this morning, mainly across central Nebraska and north-central Kansas. Areas of reduced visibility are expected to extend into portions of east-central and southeast Nebraska, where visibilities may drop into the 2-5 mile range before improving by late morning. Through the start of the work week, a negatively tilted trough will advance from the Intermountain West into the central and northern Plains, inducing surface cyclogenesis over eastern Colorado and setting the stage for the next round of widespread precipitation. Most of the morning and afternoon will remain dry, with perhaps a stray light shower or two (PoPs 15-30%). Highs are expected to climb into the mid to upper 50s. The main forcing for ascent arrives this evening and overnight as a cold front pushes through, bringing PoPs of 60-85%. The most persistent and widespread rainfall is expected between midnight and 7 AM Tuesday, with overnight lows in the low to mid 40s ensuring precipitation remains all rain. Rain will gradually taper off through the day Tuesday (PoPs 20-30%), as the system pushes eastward. In its wake, a tightening surface pressure gradient will produce gusty northwesterly winds of 30-35 mph, just shy of wind advisory criteria. Highs will struggle to reach the low 50 degrees, and with the wind, apparent temperatures will generally linger in the upper 30s to low 40s. Overall, Tuesday will be an unpleasant day marked by chilly temperatures, blustery winds, and lingering rain. Rainfall totals of 0.25 to 0.75 inches are expected for most. The highest totals are forecast across western Iowa, gradually decreasing westward into eastern Nebraska. Wednesday and Beyond... Low-end precipitation chances (15-30%) may linger into early Wednesday as the region remains under the influence of cyclonic flow, though additional rainfall totals will be minimal. Behind the departing system, Wednesday will be a chilly day with highs only reach the upper 40s to low 50s and lingering north-northwesterly wind gusts up to 30 mph. Cloud cover should finally begin to break up Wednesday night into Thursday, allowing Thursday morning lows to drop to near or slightly below freezing in some areas. Temperatures may even dip into the upper 20s in east-central Nebraska. As the trough continues to pull east through the latter half of the week, a subtle warming and drying trend will take hold. Highs will rebound into the 50s on Thursday and Friday, with overnight lows in the low to mid 30s. By the weekend, temperatures will continue to moderate as surface high pressure overspreads the area, with highs climbing into the upper 50s to 60s and low ranging from the mid 30s to low 40s. && .AVIATION /12Z TAFS THROUGH 12Z TUESDAY/... Issued at 526 AM CDT Mon Oct 27 2025 MVFR to IFR conditions are expected to prevail through the forecast period as low-level cloud cover holds in place. As of 10:30Z, all three terminals remain in MVFR conditions. Ceilings will generally decrease to more widespread IFR conditions this morning before improving back to MVFR this afternoon. Winds will remain out of the southeast at 10-14 kts before a cold front pushes in from the west this evening. The front is expected to reach KOFK by 00-02Z and KOMA and KLNK closer to 06-08Z. The front will bring a clockwise shift in winds to westerly and eventually northwesterly as well as rain showers and the return to IFR conditions to all terminals. && .OAX WATCHES/WARNINGS/ADVISORIES...
