KEY MESSAGES

Updated at 132 PM CDT Tue Jul 7 2026

- Moderate risk of heat-related impacts this week, with peak heat indices between 103-108 degrees.

- Low chances of daily isolated showers and thunderstorms over the Coastal Plains through Thursday. Rain chances increase east Friday and Saturday.

DISCUSSION

Issued at 132 PM CDT Tue Jul 7 2026

A mid-level weakness stretched from Arkansas across Del Rio and over Mexico has split the ridging over the region and is allowing for a bit of an increase in lower to mid-level moisture today. This should help develop at least isolated sea breeze showers this afternoon and evening. Some Mexican convection is also possible late this evening into tonight, but if it does make it to the Rio Grande would expect it to hold pretty close to there, and not extend across South Texas.

As ridging regains control tomorrow, mid-level moisture advection isn't quite as strong and would expect a slightly less active sea breeze, but an isolated shower or storm would still be possible.

A better push of tropical moisture moves into the area late Thursday through Saturday with an associated mid-level disturbance trying to push into the area, mainly along the coast. This will provide a better chance for showers and storms, especially through the Coastal Plains and the Victoria Crossroads. Rainfall totals overall are not expected to be especially high, but with PWAT values of 2-2.5", some heavy downpours with localized totals around an inch would be possible, most likely in the Victoria Crossroads.

Temperatures remain near to even slightly below normal - if it feels like we've been saying that a lot, we have! In fact the number of days with temperatures more than 4 degrees above normal May1-now this year is a fraction of what we've seen over the past several summers! (3-6 days across the area for this year.) A lot of this is probably related to much wetter than normal period we've had. Lets hope I didn't jinx it! Anyway - seasonal temperatures continue with highs in the 90s daily. Overnight lows will be in the mid 70s to lower 80s. Heat index values generally range between 103 and 108 daily.

AVIATION

(18Z TAFS) Issued at 132 PM CDT Tue Jul 7 2026

Will continue a typical summertime diurnal pattern across the area through this period. Scattered CU during the day with scattered to broken lower strato-cu overnight. We are seeing isolated sea breeze showers and storms today, and have included the mention of VCSH at ALI and VCT this afternoon, though a thunderstorm isn't out of the question. Convection it mainly behind CRP at the time of issuance, and confidence is too low to include in LRD or COT at this time. While briefly moderate winds will be possible in the late afternoon and evening, gusts will generally remain below 20kt.

MARINE

Issued at 132 PM CDT Tue Jul 7 2026

Gentle to moderate south-southeasterly winds (BF 3-4) will persist into midweek before becoming primarily moderate to fresh (BF 4-5), particularly across the southern bays and southern nearshore waters. Low daily rain chances will also continue through much of the week before increasing by late week and into the weekend.
