KEY MESSAGES

Updated at 612 AM CDT Wed Jul 8 2026

- Low rain chances through Thursday along the Coastal Plains, medium rain chances Friday into the weekend.

DISCUSSION

Issued at 237 AM CDT Wed Jul 8 2026

South Texas lies within a mid-level weakness stretching SW from Arkansas into NE Mexico which is currently splitting ridging over the Fl Peninsula and ridging over the SW US. Although this weakness will persist some subtle height rises will be observed tomorrow with PWATs generally in the 1.6 inch range (near normal). Any storms should be sea-breeze driven with coverage largely being isolated (15- 25%) and focused over the Coastal Plains in the afternoon. Although a surge of tropical moisture will approach the area from the southeast on Thursday, it's leading edge should not reach the area until after peak diurnal heating, so expect similar isolated sea- breeze activity.

The aforementioned moisture plume (PWATs up to 2-2.3 inches) and accompanying mid-lvl easterly disturbance will approach the area late Thursday into Friday bringing increasing rain chances Friday into Saturday. At the moment the system looks progressive enough that the rain will be beneficial and manageable, but naturally given those 90-95th percentile PWATs some areas will see heavy downpours and isolated high rain totals. Rain chances Sunday into early next week will be dependent upon if the disturbance and moisture plume lift north-northeast of the area, or remains near the area. For now NBM suggests isolated PoPs but these may need to be increased as the time period approaches.

High temperatures remain near normal through the period with highs ranging from 90 near the coast to around 100 in the Rio Grande Plains. Lows will range from the mid 70s to the lower 80s with the spatial gradient reversed from the highs (as is typical in southeasterly flow). Peak heat index values generally range between 103 and 108 daily.

AVIATION

(12Z TAFS) Issued at 612 AM CDT Wed Jul 8 2026

A couple of sites will remain below VFR due to low ceilings and visibilities early this morning. By mid-morning, those sites should rebound back to VFR conditions. Winds will remain light this morning before increasing in the afternoon with gusts to 20-24 knots.

MARINE

Issued at 237 AM CDT Wed Jul 8 2026

Gentle to moderate south-southeasterly winds (BF 3-4) will persist through the workweek. Low daily rain chances will also continue through much of the week before increasing into the moderate range by late week and into the weekend.
