.SHORT TERM... (Today) Issued at 1214 AM CDT Wed Oct 15 2025
Another dry, unseasonably warm, and humid mid-October day is in store today as potent mid/upper-level ridging shifts northward over southeast OK and western AR by this afternoon. Very little, if any at all, cloud cover will help temperatures warm up into the mid-80s for most locations (10-15 degrees above seasonal average) with a few locations reaching the upper-80s west of Highway 75 in OK. High pressure across the Upper Midwest and Great Lakes regions will maintain light to moderate southeast/east winds through the daytime.

.LONG TERM... (Tonight through Tuesday) Issued at 1214 AM CDT Wed Oct 15 2025
Unseasonably warm and dry weather will continue through most of the remaining workweek as persisting ridging remains intact over eastern OK and western AR. Changes in the weather pattern will finally commence beginning on Friday as a robust upper-level low over the Rockies lifts northeastward across the Northern Plains late Thursday night into Friday morning. As a result, a surface low will develop across eastern CO and scoot eastward, dragging a cold front across the Plains during the daytime Friday. Southerly low-level winds are expected to increase and become gusty ahead of the cold front Friday afternoon, eventually aiding in advecting a plume of low-level moisture into the forecast area Friday night into Saturday morning. Sustained wind speeds between 15-20 mph, with gusts 30-35 mph will be common during the daytime Friday, especially across northeast OK and northwest AR.
Deterministic models show scattered thunderstorms developing along and just ahead of the advancing cold front across central KS and western OK by late Friday afternoon or early evening. There are still some differences in model solutions on timing of the cold front, but in general the front is expected to move into the forecast area late Saturday morning or early Saturday afternoon and exit south and east of the area Saturday night. As instability, bulk shear, moisture, and lift all begin to increase Friday night into Saturday morning along and ahead of the front, the severe thunderstorm threat will also increase. Though isolated severe storms will be possible along and ahead of the approaching front late Friday night into Saturday morning, most probable severe timing threat looks to occur Saturday afternoon into Saturday evening, when models suggest instability, shear, and lift all maximize along and ahead of the frontal boundary across far eastern OK, southeast OK, and western AR. All severe modes look possible, with large hail and damaging winds being the two main threats. Still lots of uncertainty of how everything evolves, especially if there is ongoing convection Saturday morning. But ingredients will be in place for scattered strong to severe storms through the daytime. Better details to come in later updates.
Temperatures will be a bit of a roller coaster from the end of this week into the early part of next week. Unseasonably warm daytime and nighttime temperatures will pursue through Saturday, with Friday being the warmest day as strong warm air advection occurs ahead of the approaching cold front. Temperatures on Saturday will be tricky and highly dependent on speed/location of the cold front as well as how quickly clouds clear out behind the frontal boundary. A quicker- moving front will result in cooler temperatures than what is currently forecast. Temperatures will cool to near or just below seasonal averages Saturday night, Sunday, and into Sunday night behind the cold front. Upper-level ridging will quickly build in over the region during the daytime on Monday with models showing modest to strong warm air advection occurring in the low-levels ahead of another approaching storm system. This, in theory, will warm temperatures back up above seasonal average on Monday and again on Tuesday before the next cold front pushes through late Tuesday night into Wednesday of next week.
