Updated at 632 PM CDT Thu Jun 4 2026 - Scattered storms this afternoon with a few becoming strong to locally severe. Main hazards will include large hail and damaging wind gusts. - Increasing rain and storm chances Friday and into the weekend. A few storms could become strong to severe. - Near to above normal temperatures heading into next week with a potential for triple digit heat. && .NEAR TERM... (Rest of today and tonight) Issued at 206 PM CDT Thu Jun 4 2026 A MCV is spinning across central Kansas and will continue to lift northeast with storms associated with the circulation keeping north of the forecast area. Cumulus clouds across norther into western Oklahoma and western north Texas have developed late this morning with a few isolated to scattered storms developing. Storms are developing on the eastern side of a weak surface trough draped north to south across West Texas. Bulk shear is expected to be less than 20 knots with short-lived updrafts. Sufficient MLCAPE will support a few strong to locally severe storms with hail and damaging winds as the primary hazards. Area of greatest potential for storms will be across southwest Oklahoma and into north central Oklahoma through this evening. && .SHORT TERM... (Friday through Saturday night) Issued at 206 PM CDT Thu Jun 4 2026 In the wake of the shortwave that moved through the Central Plains Thursday, an upper closed low will develop pin northwest Mexico Friday. This will help feed subtropical moisture into the Southern Plains, but overall the forcing aloft will remain weak over Oklahoma. Thus, any storms that develop will rely on diurnal heating Friday afternoon as a weak trough sets up closer to the NM/TX state line. If a storm or two can develop, hail and winds will remain the primary hazards. The upper low will shift northward into the Permian Basin Friday night and then West Texas by Saturday. Rain and storm chances will increase from south to north into Saturday as the upper low brings lift and moisture into the forecast area. Strong to locally severe storms cannot be ruled out, especially Saturday as the upper low is over the Texas Panhandle and flow aloft increases. Several rounds of rain and storms Friday into Saturday could give way to localized flooding in some areas as heavy rainfall is likely to accompany any storms that develop. Temperatures will be near or above normal Friday before cooling slightly towards normal or slightly below Saturday with increased cloud cover and rain chances. && .LONG TERM... (Sunday through Wednesday) Issued at 149 AM CDT Thu Jun 4 2026 Storm chances will likely continue Saturday night into much of the day on Sunday as the upper low lifts into OK, though we will likely see a gradual transition of rain chances eastward over time as the trough axis translates to our east by Monday. Uncertainty increases for the middle of next week as models which had previously shown continued storm chances associated with another trough over the western/central US are now showing this trough remaining further north and west with ridging building over the southern Plains instead. If this were to occur, decreasing precipitation chances and hotter temperatures would be expected for the middle to latter portion of next week. Ware && .AVIATION... (00Z TAFS) Issued at 632 PM CDT Thu Jun 4 2026 An isolated thunderstorm ongoing near Enid is expected to dissipate with sunset, and wind gusts will subside as well around that time. Within a few hours of dawn on Friday morning, MVFR ceilings are likely (60% probability) from PNC to SWO to OKC to OUN and DUA. There is a medium probability of this occurring at LAW. MVFR conditions are anticipated to lift by mid-morning. There is a low chance of showers and thunderstorms on Friday afternoon - mainly across southern Oklahoma and adjacent north Texas. && .PRELIMINARY POINT TEMPS/POPS...
