KEY MESSAGES

Issued at 1209 PM CDT FRI OCT 30 2026

- Halloween Evening: A rainy weekend is brewing in the cauldron, but the trick-or-treating outlook is losing its fright factor. We expect the skies to hold their watery spells until after the witching hour, but keep your enchanted rain cloaks and umbrellas on standby just in case a rogue shower tries to dampen your spirits!

- Midweek rain: Another weather system will move into the area around the middle part of next week bringing increased rain chances.

DISCUSSION

(This afternoon through Thursday) Issued at 1209 PM CDT FRI OCT 30 2026

Water vapor imagery early this afternoon reveals a shortwave lifting across Texas. A plume of deep moisture associated with the remnants of Tropical Storm Vance accompanying this upper level feature will combine with a swath of healthy PWATs coming in off the Gulf, promoting increased rain chances over the weekend. While the greatest chances look to come overnight, we will carry low chances (20-30%) Saturday afternoon so keep that in mind before heading out for some trick-or-treating. With that said, some of the higher resolution guidance continues back off in coverage. Otherwise, the shortwave is expected to slowly lift northeastward through the day on Sunday, leaving low to medium chances for rain through Sunday evening.

Weak ridging early next week will lead to a few rain-free days before our next system arrives by mid week. There are several details we will need to work out over the coming days such as how far south the upper level low moves and how quickly it tracks through the region. For now, we will carry a moderate (40-60%) chance of showers and storms as ample moisture will be in place ahead of this system.
