SHORT TERM
(Today through Monday)
Issued at 256 AM CDT Sun Jun 2 2024

Key Message:

-Above normal temperatures continue

Generally quiet weather will prevail in the short term. A mid-level ridge will remain in place, supporting dry and warmer than normal weather. High pressure over the Gulf will fuel moderate to breezy southeast winds. High temperatures will top the century mark for most inland locations today and Monday. Heat index values will range from 105 to 110 degrees for a few hours each afternoon, and could briefly go to 111 or 112 degrees in some areas. Decided to forego a heat advisory for now based on the borderline conditions. Low temperatures will be near 80 tonight. The movement of a short-wave trough through the ridge could trigger Sierra Madre Oriental convection tonight, but models keep any significant precip west of deep South Texas. For those going to the beach, a moderate rip current risk will prevail today and tonight, possibly shifting to high on Monday as wave heights and swell periods increase.

LONG TERM
(Monday Night through Saturday)
Issued at 256 AM CDT Sun Jun 2 2024

500 mb high pressure initially centered over northern Mexico will gradually build northwest through the period, eventually becoming centered over the Four Corners area of the United States. This pattern will produce dry weather across the BRO CWFA through the long term forecast period. However, some model guidance suggests that a shortwave riding within the mid-level flow may generate some convection over the higher terrain of neighboring Mexico Monday night, which may then propagate into the far western portion of the BRO CWFA. The potential for this will need to be monitored by successive shifts, especially since the Storm Prediction Center places Zapata County in a general risk of thunderstorms at that time. For now, however, the forecast will be dry as previously stated.

Meanwhile, well above normal daytime high temperatures are also anticipated. The combination of ambient air temperatures and relative humidity percentages will support a HEAT ADVISORY for portions or all of Deep South Texas and the Rio Grande Valley Tuesday and Wednesday, with a SPECIAL WEATHER STATEMENT for the remainder of the daylight hours of the period.

Finally, the interaction between thermal low pressure over Mexico and high pressure over the Gulf of Mexico will create a breezy to windy onshore flow through the period. Despite the enhanced pressure gradient, a WIND ADVISORY is not expected to be needed.

AVIATION
(12Z TAFS)
Issued at 607 AM CDT Sun Jun 2 2024

MVFR at KMFE and KHRL due to ceilings while KBRO has gone ceilingless. Southeast winds will pick up to breezy and gusty today and remaining ceilings should scatter out. Low clouds will develop this evening, with ceilings lowering to MVFR. Winds will remain moderate overnight.

MARINE
(Today through Monday)
Issued at 256 AM CDT Sun Jun 2 2024

Moderate to fresh breezes and moderate to slightly elevated wave heights will prevail. Small craft should exercise caution conditions will dominate, with marginal small craft advisory conditions on the Gulf possible by tonight. High pressure will continue ridging into the Gulf from downstream, supporting the enhanced winds and seas.

(Monday Night through Saturday)
Small Craft Advisory conditions will exist along the Lower Texas Coast through the first half of the period courtesy of thermal low pressure over Mexico interacting with high pressure over the Gulf of Mexico. Marine conditions will improve to Small Craft Exercise Caution criteria Wednesday night through Thursday, with even more improved winds and seas for Friday and Saturday, as high pressure builds farther west into the western Gulf of Mexico and weakens the pressure gradient.
