FXUS63 KOAX 091727 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 1227 PM CDT Thu Jul 9 2026 .KEY MESSAGES... - A stretch of hot weather is expected this weekend into next week, with highs in the 90s and heat indices approaching 100 degrees. - Most days are looking dry through the next week, though we could see a few spotty showers and storms Friday. Severe weather is not expected. && .DISCUSSION... Issued at 1047 PM CDT Wed Jul 8 2026 Tonight through Friday... A cluster of thunderstorms have developed along a front draped across northeast Nebraska earlier this evening, supported by a shortwave trough pushing across the northern Plains. Rather limited deep-layer shear (around 20 kts) has kept the initial storm development rather stationary along this boundary. Ample instability (MLCAPE > 2500 J/kg) along with the sufficient shear has brought pockets of strong to severe storms along this cluster. Cold-pool development behind the line will lead to an eventual southward push of this system into the overnight period. As the cold-pool helps force the storms into more of an upscale cluster, isolated pockets of damaging wind gusts (pockets of 60 mph) will be one of the primary hazards over the next few hours, aided by DCAPE of 1000-1200 J/kg. The severe weather potential will gradually decay into the overnight period. Locally heavy rainfall and flash flooding will remain another concern. PWAT values near 1.80-2" (above the 90th percentile of sounding climatology) and warm cloud depths of 4 km have brought efficient rainfall processes, especially when coupled with the longer residence time. Pockets of 3- 4.50 inches of rainfall have been reported, with the highest totals in western Iowa. CAM guidance continues to hint at a few scattered storms redeveloping behind the main cluster overnight, though the severe weather potential will be limited with these storms given the increasing inhibition and decreasing shear. Storms will push southward across the area overnight, clearing much of the forecast area by 7 AM. Can't rule out a few afternoon storms redeveloping along the front in far southeast Nebraska and southwest Iowa, though the better shear and instability should stay just to our south. The lingering cloud cover and slightly cooler air mass will bring afternoon highs in the low to upper 80s. Similar temperatures are expected on Friday with partly cloudy skies. Saturday and Beyond... This weekend into early next week, an amplifying mid- to upper-level ridge is expected to build over the Front Range and gradually expand eastward into the mid-Missouri Valley, leading to a warming trend and relatively dry conditions. Highs on Saturday and Sunday will take a step upward into the upper 80s to mid 90s. By Monday, most locations are expected to reach the 90s a few spots in northeast Nebraska expected to reach the triple digits. Overnight lows will remain in the low 70s. Heat index values are expected to reach the mid 90s to around 105 degrees daily. This hot pattern with minimal precipitation chances will continue into the work week. && .AVIATION /18Z TAFS THROUGH 18Z FRIDAY/... Issued at 1227 PM CDT Thu Jul 9 2026 Expect MVFR ceilings early in the period to scatter out with cloud bases generally rising through the afternoon and VFR conditions thereafter. Some guidance hints at some showers and isolated storms pushing toward the area 12-15Z Friday, but chances currently remain below 20%, highest at OFK and LNK, so did not include mention at this time. Otherwise, winds will be light and northerly to northeasterly through most of the period, though should become southeasterly at OFK toward 03Z. && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None.
