.SHORT TERM... (Today and tonight) Issued at 201 AM CDT Sat Sep 20 2025
Expect hot and dry conditions again this afternoon. Also, mostly sunny skies will make it feel even hotter. Highs will be in the lower to mid 90s which is above normal for this time of year. Scattered thunderstorms will probably develop this afternoon across the Panhandle and Oklahoma in a warm sector with moderate instability. These storms may make it south into the northern Big Country late this evening and overnight. Going with low chances of rain late tonight. No severe weather is expected but storms may produce gusty winds.

.LONG TERM... (Sunday through Friday) Issued at 125 AM CDT Sat Sep 20 2025
An embedded disturbance will move across northern Texas on Sunday. This may be enough to support a low chance for an isolated rain shower or thunderstorm through Sunday. Thunderstorm chances (20-30%) will largely be limited to areas near the I-20 corridor and northward given the track of this disturbance.
By Tuesday and Wednesday, both the GFS and the ECMWF indicate a low pressure system developing across the Plains. The GFS and ECMWF are showing a similar solution tracking the low across Kansas, which is a bit further north than yesterday`s model runs. Regardless, we may see a weak cold frontal boundary move into the area on Tuesday night into Wednesday because of this system. This frontal boundary will serve as a focal point for scattered thunderstorms (30% chance) across our area as it moves through. Slightly cooler temperatures will also result, but highs will still remain in the middle to upper 80s.
