FXUS63 KOAX 040447 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 1147 PM CDT Tue Jun 3 2025 .KEY MESSAGES... - Rainfall activity will gradually end throughout the day, with some lingering showers into the evening hours - Temperatures will be much cooler this afternoon compared to the last few days, with afternoon readings only maxing out in the lower to middle 60s. - Drier and warmer conditions are expected for Wednesday, with rain chances returning for Thursday through Saturday (20-50%). && .DISCUSSION... Issued at 1228 PM CDT Tue Jun 3 2025 Regional radar mosaic reveals scattered showers across Eastern Nebraska and southwestern Iowa this afternoon. These showers are in addition to rainfall that occurred last night across the forecast area that dropped some decent amount across mainly Northeast Nebraska where areas saw upwards of 1-2". Southeastern NE was not so lucky last night as accumulations were generally around a few tenths of an inch, but these areas have caught up with the additional morning and early afternoon rainfall. Precip activity will be on the downtrend through the remainder of today with models indicating it should be clear of our area by early this evening. With vastly different atmospheric setup compared to what we had seen yesterday and this past weekend, temperature this afternoon will be noticeably cooler, a good 25-30 degrees cooler, with afternoon readings only maxing out in generally in the lower to middle 60s. With moisture abound across the region, it would not be surprising to see some fog development into the early morning hours Wednesday, resulting in some hazardous travel conditions in certain spots. .WEDNESDAY AFTERNOON... Wednesday looks to be a much more tranquil day as the broader atmospheric pattern becomes more zonal. Rising 500mb height anomalies to near climatological normal levels will translate to warmer day-to-day temperatures, with highs Wednesday afternoon ranging mostly in the middle 70s. It should be quite the nice day to get outside as dewpoints will only be in the upper 40s and lower 50s, making conditions feel fairly pleasant. There will still be a decent amount of clouds around, but rainfall is not in the forecast for this timeframe. .THURSDAY... Diffluence in the mid-levels, combined with upper-jet influenced ascent and modest moister profiles will help increase the chances for shower and thunderstorms once again on Thursday. Right now, dynamics do not look overly impressive to produce severe weather, and there are no other indications (either from the SPC or machine learning guidance) to reflect any enhanced potential for strong thunderstorms. Also, with the lack of a flash point for convection (i.e. a frontal boundary) any activity will likely be more spotty in nature. MaxTs look a little cooler compared to day prior, with values ranging from the upper 60s to mid 70s. .FRIDAY INTO THE WEEKEND... Friday and Saturday both look like they will continue the active weather streak as potentially multiple troughs traverse the Northern and Central Plains. Much like Thursday, machine learning guidance is not picking up any severe threat at this time, but with still being several days between now and the end of the week, the forecast can certainly change. Temperatures will max out around 80 degrees or so on Saturday. && .AVIATION /06Z TAFS THROUGH 06Z THURSDAY/... Issued at 1144 PM CDT Tue Jun 3 2025 Patchy fog, becoming dense at times, will be the primary concern tonight. Patchy areas of MVFR to LIFR conditions will be possible. The highest confidence in fog tonight with be at KOMA, though amendments will be made as needed given the low confidence in how widespread fog will be. Otherwise, winds will be calm and out of the northwest before veering to northeasterly though the late morning. Skies will be mostly clear with a scattered cloud deck at FL060-080 and a few upper- level clouds. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None. IA...None. && $$ DISCUSSION...RW AVIATION...Wood
