New AVIATION
SHORT TERM
(Today through Sunday)
Issued at 357 AM CDT Sat Jul 27 2024
BRO radar currently shows scattered convection across the Lower Texas coastal waters with lighter activity inland across portions of the CWA In addition, a more widespread area of showers and isolated thunderstorms were located south of the Rio Grande River, across Mexico, with movement to the north. Some of this convection could reach portions of the Upper Rio Grande Valley before daybreak. The latest HRRR is verifying well, so far, and suggests additional convection will develop and linger across the area through around mid-morning with additional development this afternoon.
Unsettled weather will continue today into tonight due to the combination of deep tropical moisture (PWATs 2.2 to 2.5 inches), a deep mid to upper level trough/low and a weak area of surface trough across Deep South Texas. Another round of showers and thunderstorms are expected to develop across the area today, especially in the afternoon/early evening. Any activity that does develops today will be able to produce locally heavy rain, which may result in nuisance type flooding. The area remains in a general thunderstorm outlook through Sunday and a marginal excessive rain outlook through tonight.
The 500mb trough/low moves further east on Sunday as mid-level ridging builds into the region. Lingering moisture and weak forcing may support isolated to scattered showers and thunderstorms on Sunday.
Otherwise, mostly cloudy to overcast skies and light winds will continue. High temperatures today will range from the mid 80s to near 90. Overnight lows will be mainly in the mid 70s. A little warmer on Sunday as rain chances and cloud cover decrease.
Rip current risk will remain low.
LONG TERM
(Sunday Night through Friday)
Issued at 357 AM CDT Sat Jul 27 2024
This portion of the total forecast will have no mention of showers and thunderstorms within the BRO CWFA. This will be due to 500 mb high pressure becoming the dominant weather feature across Deep South Texas and the Rio Grande Valley, with the center of the mid- level ridge positioned just south of Louisiana, but eventually becoming reentered over north Texas by the end of the period.
Additionally, precipitable water values will decrease, and hold, to near 1.50 inches after the recent string of convection-inducing 2+ inches.
Temperature-wise, as the new work week progresses, the atmosphere dries out, and 500 mb high pressure remains dominant, highs will generally increase roughly about 1 degree every other day, such that near to slightly above normal values will be the rule and not the exception. Although a HEAT ADVISORY is not likely to be needed, heat index values will, however, support a daily SPECIAL WEATHER STATEMENT.
AVIATION
(12Z TAFS)
Issued at 638 AM CDT Sat Jul 27 2024
Light and variable winds with some passing mid to high clouds prevail across Deep South Texas. BRO radar shows some convection, mainly across the Gulf waters, early this morning. Another round of showers and pockets of thunderstorms are expected to develop later this morning into the afternoon/early evening hours. Mainly VFR conditions are expected for the next 24 hours, except MVFR conditions will be possible in and around any convection.
Southeasterly winds are generally expected, with some variability near any showers and thunderstorms.
MARINE
(Today through Sunday)
Issued at 357 AM CDT Sat Jul 27 2024
Light to moderate winds and low to moderate seas will prevail through Sunday as high pressure continues across the Northern Gulf. Unsettled weather is expected through much of the period with scattered showers and isolated thunderstorms. Enhanced winds and seas will be possible near any convection.
(Sunday Night through Friday)
Surface high pressure over the Gulf of Mexico will interact with thermal low pressure over inland Mexico through this portion of the total marine forecast. Although low to moderate seas are anticipated, moderate to breezy winds will occur, resulting in occasional Small Craft Should Exercise Caution for the Laguna Madre and Gulf of Mexico waters from 0 to 20 nautical miles offshore.
