KEY MESSAGES

Issued at 135 PM CDT Sat Jul 11 2026

- Increasing thunderstorms are expected today, from the south this afternoon and from the north into the evening. Oppressive heat in the middle 90s is expected again ahead of these storms.

- Scattered to numerous showers and thunderstorms are expected Sunday through Tuesday of next week. Stronger storms may produce damaging wind gusts and locally excessive rainfall. Those with outdoor plans may have to shelter from storm threats, including lightning.

DISCUSSION

Issued at 130 PM CDT Sat Jul 11 2026

A seasonally significant upper level disturbance will be pivoting cyclonically around a building upper ridge (heat dome) over the Northern Plains through midweek. This development, along with a frontal boundary oozing south, will work with a moist, humid, and unstable air mass in place across the Four State Region to bring periods of scattered to numerous showers and thunderstorms now through Tuesday. Severe weather cannot be ruled out in this period, although area-wide strong to severe storm opportunities are concentrated more on Sunday when SPC maintains the Marginal Risk for severe storms over nearly all of the SHV coverage area. The main risk with any severe storms will be damaging winds gusts. In addition to the lower end severe storm risk, this weather regime will also bring at least low end potential for locally heavy rainfall with WPC Marginal Risks for Excessive Rainfall in mainly far northern zones tonight, most of the area tomorrow, and mainly along and south of the I-20 on Monday and Tuesday. Total rainfall amounts through Tuesday will generally range from 0.5 to 1.5 inches, although isolated areas have a decent probability of experiencing 2+ inches of rainfall, particularly along and south of the I-20 corridor.

Heat stress will be just a little shy of Heat Advisory criteria in most areas today, but the increased clouds and precipitation Sunday through Tuesday should keep heat in check with lows generally in the low to mid 70s and highs in the upper 80s to lower 90s. But the July heat cannot be held at bay too long in the Four State Region and the influence of the high pressure ridge to the north in the short term will grow Wednesday into Thursday as rain chances back off a good deal. High temperatures will increase to mostly low to mid 90s by Thursday and into the mid and upper 90s by Friday and into next weekend, when Heat Advisories may be necessary yet again. /50/
