SHORT TERM /THROUGH THURSDAY NIGHT/

Issued at 341 PM CDT Wed Sep 2 2026

Tonight...An upper trough will extend across the Northwestern U.S. with a closed low off the coast of WA/OR. Meanwhile, an upper ridge remains centered over the Southeast U.S. Across the Central Plains, southwest flow aloft remains established. A shortwave disturbance currently located from southeast WY and north central CO will track northeast this evening and overnight. Convection will initiate across the higher terrain to our west this afternoon, tracking into the northwest Sandhills this evening and overnight. Soundings indicate an inverted-V up to 600mb, and downdraft CAPEs up to 1200 J/kg. This supports a threat for locally severe wind gusts this evening. The area of concern is for areas west of Lisco through Merriman. The latest CAMs are in good agreement on the location and timing, ending by 12Z. The latest few runs of the RRFS do continue the threat for showers/storms across the central Sandhills into Thursday morning, so this remains a possibility. Lows tonight in the low to mid 60s.

Thursday...the upper level ridge builds into the region slightly. Highs in the lower 90s, except around 95 southwest. Across the western Sandhills, northwest winds 10 to 20 mph and afternoon humidity as low as 15 to 25 percent will create elevated fire concerns. While a few morning showers can't be ruled out Thursday morning, dry conditions are expected Thursday afternoon into Thursday night.

LONG TERM /FRIDAY THROUGH WEDNESDAY/

Issued at 341 PM CDT Wed Sep 2 2026

Upper level ridging will gradually build into the region Friday and Saturday of Labor Day weekend. This will bring very warm temperatures in the low to mid 90s, with upper 90s southwest. Atmospheric moisture from New Mexico and Colorado will increase into the region with south southwesterly flow aloft. Low chances for showers/thunderstorms southwest and east Friday night, with low chances across much of the area Saturday night. By Sunday and Monday, the upper ridge may begin to flatten out as an upper trough moves front the Intermountain west into the Northern Plains. Highs remain around 10 degrees above normal in the upper 80s to lower 90s. PWATs will increase some during this time with chance POPs Sunday night and again Monday night. NBM 24 hours probability of exceeding 0.25 inch ending 12Z Monday and again 12Z Tuesday, ranges from 20 to 40 percent.

The upper trough is forecast to flatten out by next Wednesday as an upper trough moves into the Great Lakes. This may bring some relief from the heat with highs from 80 to around 85.
