LONG TERM
(Sunday through next Friday)
Issued at 206 PM CDT Fri Jul 26 2024

Lingering moisture and weak forcing could support isolated to scattered showers and thunderstorms Sunday. The upper level trough will move further east Sunday, as an upper level ridge takes hold over the Central US by Monday. This will support drier conditions and warmer temperatures through the remainder of the period, as the ridge looks to strengthen through the period. Rain chances look to remain near zero Monday through Friday.

Clearing skies and continued southerly to southeasterly flow will allow afternoon how temperatures to climb back into the mid to upper 90s through the period. Heat indices look to top out around 108-110 each afternoon, remaining just below Heat Advisory criteria. Low temperatures look to be in the upper 70s to low 80s through the period.

AVIATION
(18Z TAFS)
Issued at 1111 AM CDT Fri Jul 26 2024

VFR conditions at the TAF sites. Very light winds and a few mid clouds. Deep moisture is still transiting the region, just a bit upstream over the mid-valley right now. HRRR suggests some showers may get going over the lower valley later this afternoon.
Guidance is suggesting generally VFR conditions with possible lowering and thickening to MVFR overnight. Would expect VFR through late this evening otherwise, except near hit and miss showers or thunderstorms.

MARINE
Issued at 206 PM CDT Fri Jul 26 2024

Tonight through Saturday night...Due mainly to high pressure across the North Gulf, light to moderate winds and low to moderate seas will prevail through Saturday night. Unsettled weather will continue into Saturday night with scattered showers and isolated tstorms.
Enhanced winds and seas will be possible near any convection. I do not expect SCEC nor SCA conditions.

Sunday through next Friday...High pressure looks to remain over the Northern Gulf through the period, supporting generally light to moderate winds and slight to moderate seas. The interaction of the aforementioned high and a strengthening thermal low over Northern Mexico could result in tighter pressure gradients Tuesday and Wednesday along the Lower Texas Coast. This will likely result in higher winds along the Laguna Madre, and may require Small Craft Should Exercise Caution headlines for the Laguna Madre Tuesday and Wednesday.
