DISCUSSION

Issued at 1219 PM CDT Mon Jun 8 2026

A subtropical jet streak and associated enhanced mid/upper-level moisture remains over the area but will continue to weaken/push eastward as subtropical ridging builds westward from the Gulf. Earlier light rain with this feature has dissipated, though some patches of light rain/sprinkles may still occur along the coast this afternoon and evening. Otherwise, isolated to widely scattered showers and storms will continue to develop over inland areas, with the relatively highest chances in the Brazos Valley. Activity will diminish this evening. Subtropical ridging will be centered over Southeast Texas through the week. This will prevent widespread convection, but still expect isolated to scattered showers and storms to develop each afternoon with daytime heating, onshore flow, and the sea breeze. Highs will mainly be in the lower 90s. Taking into account the typical high bias of NBM dew points, there will only be a low chance of heat indices reaching heat advisory criteria. But heat will certainly still be a concern for those not acclimated to it. Towards the end of the period, the ridge may start to weaken as troughing amplifies over portions of the central and eastern CONUS. This may result in an increase in convective coverage starting around Sunday with some frontal boundaries stalling north of our area, but details remain uncertain at this time.

AVIATION

(12Z TAF Issuance) Issued at 1219 PM CDT Mon Jun 8 2026

Prevailing MVFR ceilings at most terminals this morning with isolated pockets of IFR ceilings. Expect ceilings to improve to VFR by the late morning hours. A band of lingering light rain along and south of the I-10 corridor is anticipated to persist through most of the morning hours before gradually dissipating. In the early afternoon, there is potential for isolated thunderstorms to develop mainly north of I-10. Confidence is not high enough to include any thunder in this set of TAFs, but did include some PROB30's for SHRA as greatest confidence on afternoon activity is CXO and northward. Winds will be southeasterly around 10-15 kt with gusts up to 18-23 kt at times through the afternoon. Any lingering rain will dissipate around 00Z with MVFR to IFR ceilings filtering in again overnight into Tuesday morning.

Southerly to southeasterly winds will persist for the week, with winds dipping in and out of small craft exercise caution criteria. Winds this afternoon and tonight will be right around 14-15 kts, but will not include caution flags at this time. Caution flags may be needed towards the middle of the week. Isolated showers and storms are still possible but chances will decrease slightly as the week goes on.
