DISCUSSION

Issued at 932 AM MDT Thu Sep 10 2026

Starting today and through Saturday, the borderland will be trending toward a mostly dry and warmer pattern as high pressure builds aloft over the the desert southwest. Northeasterly flow surrounding the high will bring in dry, continental air from the Rockies. While sufficient moisture remains for lowland thunderstorm chances today, warmer temperatures aloft will reduce instability for the lowlands and limit thunderstorm development to mainly the area mountains for Friday and Saturday. Friday and Saturday are also forecast to be the warmest days of the week for the region, with several lowland locations running north of 10 degrees above average both days--the lower Rio Grande Valley may even reach the triple digit mark.

The weather pattern will become more active starting Sunday as a large low pressure system moving inland from the Pacific northwest will push the upper-level high eastward. This will set up a moist southerly flow aloft that will facilitate widespread thunderstorm development across the area for several days--how much rain the lowlands will get is unclear at this time. Increased moisture and rain chances will result in lower temperatures closer to seasonal averages. The long term outlook for late next week remains uncertain with long range forecast models split on whether the moisture and thunderstorm chances continue or we trend back to a drier weather pattern.
