Updated at 126 PM CDT Wed Jun 10 2026 - Severe thunderstorm risk Wednesday & Thursday; Damaging wind gusts and large hail are primary hazards. - Hot & muggy conditions continue through Thursday, with heat indices near and above 100-105 degrees each afternoon and early evening. - Active pattern continues through the weekend, with additional chances for rain and storms. Locally heavy rain/flooding possible. && .NEAR TERM... (Rest of today and tonight) Issued at 126 PM CDT Wed Jun 10 2026 Hot this afternoon with highs in the 90s to low 100s. Dewpoints in the 60s to mid 70s across the area will lead to humid conditions as well this afternoon. The hot and humid conditions will likely lead to triple digit heat index values across much of the fa with values approaching/exceeding 105 degrees, especially across the northern third of the fa. Will continue with the current configuration of the heat advisory. Temperatures tonight will remain rather warm with lows in the mid/upper 70s so not a huge relief from the heat overnight. Breezy conditions will continue across the area this afternoon due to a relatively strong pressure gradient. Occasionally have seen an isolated gust to around 40 mph in parts of western and central OK this morning which is expected to continue this afternoon. There is a risk for severe storms across parts of northern, western, and central OK late this afternoon and evening but this risk is conditional on whether storms can develop. Many models show the fa remaining dry during this period with storms remaining N in KS and W to SW of the area in west TX/TX panhandle. However, there are a few CAMs that show some storms develop/moving into the area from KS late this afternoon/evening, a storm or two developing along the dryline and approaching from the west, and/or storms developing near the dryline in parts of NW OK, if the boundary is able to move into the fa. If these storms do occur, they will have the potential to become severe with the unstable airmass over the region (CAPE 2500-3500 J/kg). Damaging winds and large hail will be the main concerns if storms can develop. Any storm potential/severe risk is expected to diminish this evening after sunset. && .SHORT TERM... (Thursday through Friday night) Issued at 126 PM CDT Wed Jun 10 2026 Models show a shortwave moving across the northern/central Plains Thursday with a cold front moving into and across at least portions of the area. There may also be a residual outflow boundary(ies) across parts of the fa Thursday but will be dependent on what occurs later this afternoon and tonight, especially in KS. Models show thunderstorms developing along the front tomorrow afternoon with shower/storm chances continuing Thursday night into Friday as the front continues to move south across parts of the area and LLJ strengthens Thursday night. Severe storms will be possible Thursday afternoon and evening with an unstable airmass over the area. Large hail and damaging winds are the main concerns with the severe storms. PWATs are also expected to be fairly high Thursday into Friday with a >60% chance of values higher than 1.75". With these PWATs, locally heavy rain that could lead to flooding will also be a concern. The hot and humid conditions are also expected to continue Thursday although there is some uncertainty due to the timing of the front. Locations south of the front will see the hot (highs in the 90s to low 100s) and humid conditions which will likely lead to at least triple digit heat index values with 105+ values possible. North of the front temperatures are expected to be a bit cooler (highs in the upper 80s/low 90s). With the uncertainty of the timing of the front as well as the potential of rain/cloud cover possibly causing issues although it may be late enough in the day that locations still see the impacts of the heat and humidity, will hold off on issuing a heat advisory for Thursday and let later shifts continue to monitor model trends and observations. However, right now a heat advisory for parts of the fa seems likely for Thursday. With the front expected to continue to move south and rain/cloud cover over at least parts of the area Friday, temperatures are expected to be cooler with highs in the 80s to low 90s. && .LONG TERM... (Saturday through Tuesday) Issued at 158 AM CDT Wed Jun 10 2026 A relatively active pattern looks to continue across Oklahoma and north Texas into the weekend, as an upper system looks to mature upstream across the Intermountain West. The most active period of rain and storms currently looks to be Saturday night into Sunday, as another strong frontal boundary sweeps north-to-south across the region. Some strong-severe storm and heavy rainfall/flooding risk is likely over the weekend, though no particular period stands above the rest at this point. Hot and humid conditions will also continue over the weekend, especially on Saturday (prior to the front), before a more prolonged and notable "cooldown" - low to mid-80s highs - arrives into early next week. Ungar && .AVIATION... (18Z TAFS) Issued at 1114 AM CDT Wed Jun 10 2026 Mostly VFR conditions are expected through the TAF period. Only exception is MVFR ceilings will return to KDUA towards the end of the period. LLWS is expected at most TAF sites late tonight into the morning. Otherwise, breezy southerly winds will continue through the period. && .PRELIMINARY POINT TEMPS/POPS...
