.SHORT TERM... (This afternoon through Friday) Issued at 1159 AM CDT Thu Sep 25 2025
A trough located over the California/Nevada state line will continue to dig southward towards the US/Mexico border, while the ridge over the western high plains will progress slightly east into the Great Plains, losing some intensity during the process. The trough over the Mississippi River will shift slightly east over Tennessee. A split flow regime will remain in place as a result with the polar jet remaining over southern Canada and the subtropical jet lingering over the southern US.
The surface high will continue to shift east, which will help guide a northerly breeze into the region as peak heating is reached Friday. Ridge-like conditions with clear skies and lows reaching into the 50s will prevail Thursday night. Highs Friday will reach the mid-to-upper 80s and low 90s in localized spots under sunny to mostly sunny skies. Post peak heating, winds will shift to northeasterly and weaken slightly. Lows Friday night are expected to range from mid 50s to low 60s.

.LONG TERM... (Friday night through next Wednesday) Issued at 1159 AM CDT Thu Sep 25 2025
Upper level ridging will generally remain the most important feature during the long term portion of the forecast. The main theme through the forecast period, then, will be one of temperatures running warmer than normal and precipitation chances generally quite limited. The biggest (although relatively minor) disruption will come with an upper level low that will bottom out near the confluence of California, Arizona, and Mexico Friday and Friday night before opening up and lifting northeastward through the weekend. Monsoonal moisture is progged to increase ahead of the low across Arizona and New Mexico with a decent chance for showers and thunderstorms there, but lift and moisture from this regime is expected to remain along and west of the CWA border with New Mexico. NBM continues to shrink the area of slight chance PoPs in time and space now only in the Saturday through Sunday time frame and limited to about one county`s width from Parmer down to Yoakum. This remains in line with expectations from this type of pattern and are accepted as is. The other factor from the western low opening and lifting northeastward will be a slight decrease in heights/thicknesses mainly Sunday and Monday with a modest decrease in forecast temperatures from the very warm (on the order of 6-8 degrees above normal) of Friday and Saturday to something closer to 2-4 degrees above normal. However, the ridge builds back in behind the departing trough with a return to highs running 6-8 degrees above normal, i.e., mainly in the upper 80s to lower/mid 90s in the middle of next week.
