633pm CDT Thu September 17 2026

(This afternoon through next Wednesday) Issued at 1243pm CDT Thu September 17 2026

A ridge is centered over Arkansas this afternoon while a drier airmass is forced along the eastern and southern periphery. PWATs are falling across the local area with the deepest moisture, and higher rain chances, shifting into the central Texas Coast and extreme northwest gulf. Temperatures are still run above climo norms for mid September, however dewpoints are slowly falling which is keeping the heat index values lower than over the past few days.

The drier airmass will continue to filter in through tonight and into Friday. Morning lows will be near climo norms for the date which will be in the upper 60s to mid 70s. Dewpoints Friday afternoon may fall into the low to mid 60s across interior locations which will produce RHs in the 30s. While not exactly low or cool, at least its hint that fall is not far away. High temperatures, however, will still run 5-10 above climo norms Fri and Sat.

Sunday into Monday the ridge aloft will weaken and higher moisture levels will move back in. Modest rain chances will return Sunday afternoon into early next week.
