GMZ100 Synopsis For Baffin Bay To Rio Grande Out 60 Nm- 938 Am Cdt Sun Jul 25 2021
Synopsis..Persistent high pressure over the western gulf of mexico will produce favorable marine conditions along the lower texas coast through the next several days. Later this week, a midlevel inverted trough moving westward across the gulf may help to develop a weak midlevel low, which will help initiate showers and Thunderstorms across portions of the coastal waters. These may lead to locally enhanced areas of higher winds and seas.

Area Forecast Discussion . UPDATED National Weather Service Brownsville TX 614 AM CDT Sun Jul 25 2021

DISCUSSION. Updated for latest aviation discussion below.

AVIATION. VFR will be the rule through the next 24 hours with light to moderate surface winds and limited cloud cover.

PREV DISCUSSION. /issued 314 AM CDT Sun Jul 25 2021/

SHORT TERM (Now through Monday): Mid-level high pressure will remain the dominant weather feature over Deep South Texas and the Rio Grande Valley during the period. The recent trend of dry weather with near normal temperatures will persist.

LONG TERM (Monday Night through Saturday): The long term will generally be seasonally hot with slight rain chances returning each day. An inverted trough/closed mid level low will develop over the western Gulf of Mexico and move into Deep South Texas at the start of the long term and very slowly edge to the west . followed by another upper level disturbance later in the week. These disturbances will feed in slightly higher PWATs than what we'll see in the short term, but they're still rather unimpressive . generally 1.5 to 1.9 inches. This pattern will allow for a slight chance of isolated to scattered showers and thunderstorms every day through Friday. Flooding continues to not be a concern at this time, so we are not expecting a repeat of last week. Temperatures will be near normal or even a few degrees below in the Rio Grande Valley. Heat indices will typically reach in the 100 to 108 degree range most afternoons.

MARINE: Now through Monday . Surface high pressure will be centered over the west to northwest Gulf of Mexico during the period. This will produce light to moderate winds and generally low seas along the Lower Texas Coast. Neither Small Craft Exercise Caution nor Small Craft Advisory are anticipated to be needed.

Monday Night through Thursday . Favorable marine conditions are expected through the week with a weak pressure gradient in place. Wave heights will generally be 1 to 3 feet with light to moderate east to southeasterly winds. An inverted trough will move into the region by mid week, increasing the chance for some isolated to scattered showers and thunderstorms across the waters Tuesday through Thursday.
