.SHORT TERM... (This evening through Saturday) Issued at 235 PM CDT Fri Sep 19 2025
Quiet weather will persist in the short term. May see an isolated shower develop in the Big Country this afternoon but most areas will remain dry. On Saturday, a weak upper level disturbance tracking across north Texas may result in an isolated shower or thunderstorm in the afternoon mainly north of the I-20 corridor. Otherwise, highs will be in the lower to mid 90s under partly cloudy skies. Morning lows will be in the 60s and lower 70s.
&&
.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.
