.KEY MESSAGES...
- Surface high pressure will allow for dry conditions with cooler than normal night time lows tonight.
- Temperatures will warm Wednesday and the latter part of the week into the weekend as surface high pressure weakens and winds become more from the east and southeast.
- An upper level high will build over the region late in the week into the weekend keeping rain chances out of the forecast.

.SHORT TERM... (Today through Friday night) Issued at 1212 AM CDT Wed Sep 10 2025
Tonight is expected to be the last day of beautiful below norm temps with current temps already lower than the norm and likely to drop by another 2 to 4 degrees under clear skies. The surface high is steadily losing its influence over the region and a weak trough over the Gulf is helping reintroduce moisture into the area. This could also assist in seeing some isolated showers along the coastal areas, however chances still remain pretty low.
An upper ridge will build in over TX then continue to drift eastward over the end of the week and into the weekend. A warming trend will ensue, with temps rising about 2 to 6 degrees above normal.
&&
.LONG TERM... (Saturday through Wednesday) Issued at 1212 AM CDT Wed Sep 10 2025
Above average temperatures will continue throughout the entire long term period as an upper ridge builds over the Southern Plains, then remains generally in the area. This will also assist in keeping PoPs below 15 percent for the entire long term.

.MARINE... Issued at 1212 AM CDT Wed Sep 10 2025
Surface high ridging down from the northeast with a stalled frontal boundary and lower pressure over the middle Gulf.

A scattered showers or storms will be possible into Wednesday as a disturbance moves along the front, otherwise a dry airmass aloft will help keep significant shower activity out of the forecast for Thursday until the end of the period.
