DISCUSSION

Issued at 1225 AM CDT Thu Jun 4 2026

A few lingering showers and maybe an isolated storm will continue during the overnight hours before switching to land based showers and storms in the afternoon once sea breeze action followed by outflow boundaries starts to pick up. Deep moist air continues to funnel into the area and will continue through for much of the week from the gulf so storms will be very efficient rainmakers, so a few spots could see some locally heavy rainfall especially where stronger storms track or repeated rounds of storms go through. There really isn't a lot of wind support aloft so storms will likely follow on the seabreeze/outflow boundary they are before collapsing which cause some stalling in areas. For places that don't receive any or little rain from showers and storms will see high temperatures slightly above the normal highs which is currently forecast to be in the upper 80s to low 90s. Adding the humidity will put the heat index values in the mid 90s to threatening 100s especially this weekend.

AVIATION

(12Z TAF Issuance) Issued at 557 AM CDT Thu Jun 4 2026

Mixed bag of IFR to VFR ceilings with the lower ceilings currently near and north of the Houston metro area. Expect IFR/MVFR ceilings to persist through at least the mid-morning hours with the potential to stick around into the early afternoon hours. SH/TS coverage will gradually increase throughout the day with the greatest coverage expected to be around and south of the Houston metro. Highest confidence window for TS is generally between 17Z-22Z. Gusty winds and decreased visibilities/ceilings are possible within any storms. Another round of TS is expected late this evening into the overnight hours mainly south of I-10 and along the I-45 corridor. Timing for this convection is a bit more uncertain, but generally looks to be after 06Z. Another round of MVFR to IFR ceilings is anticipated overnight and into Friday morning.

Easterly to southeasterly winds will prevail through the rest of the week before turning more southerly around Saturday. Winds will be elevated with periods of small craft exercise caution to small craft advisory headlines will be likely needed at times. In addition, due to the prolonged winds there may be increased waves, rip currents, and slightly higher water levels during high tide cycle.
