New AVIATION
SHORT TERM
(Today through Tuesday)
Issued at 249 AM CDT Mon May 20 2024
500 mb high pressure will continue to build northeast out of Mexico and increasingly be even more dominant over the BRO CWFA during the period. This will have the effect of not only producing dry weather, but also well above normal, and increasing, daytime high temperatures. Heat index values will max out between 105 and 110 degrees today, with isolated spots reaching 111 degrees. Thus, will not issue a Heat Advisory for today, but will instead cover the heat threat with a Special Weather Statement. However, for Tuesday, a Heat Advisory may very well be needed, with heat indices progged to max out at 111 to 112 degrees across a more widespread area. Will hold off on issuing a Heat Advisory for Tuesday for now, and address the issue in about 24 hours (if not less than that by a successive shift) after Monday highs are tabled and new model guidance is available.
LONG TERM
(Tuesday night through Sunday)
Issued at 249 AM CDT Mon May 20 2024
A broad 500 mb ridge centered over Mexico extending into Deep South Texas and the Rio Grande Valley will maintain rain-free conditions and above normal temperatures through the period. At the surface, steady low-level southeasterly to southerly flow will result in continued humid conditions across the area.
Dangerous heat will be the main concern through the week and into Memorial Day Weekend as the mid to upper level ridge continues to build. High temperatures are expected in the triple digits across the Rio Grande Plains Wednesday afternoon with mid to upper 90s across the rest of the area, except for the 80s along the coast. The triple digit heat will expand farther eastward through the week, reaching the I-69E/US 77 corridor by Friday. The high humidity combined with the hot temperatures will lead to "feels like" temperatures ranging from upper 90s along the beaches to around 112 degrees through Thursday, and closer to 114-118 degrees Friday through the weekend, across the Northern Ranchlands and Rio Grande Valley. Overnight temperatures will remain warm with lows in the upper 70s to the lower 80s. The "feels like" temperatures each night will remain in the upper 80s and low to mid 90s. Heat Advisories may be needed for portions of the region Wednesday and Thursday, and Heat Advisories and/or Excessive Heat Warnings will likely be needed this Memorial Day weekend.
This will result in a major to extreme risk of heat-related impacts, especially towards the end of the week and into the weekend. Staying properly hydrated, limiting time spent outdoors during the peak heating of the day, taking frequent breaks in the shade, and wearing light-colored, loose-fitting clothing will be necessary to prevent any heat related illnesses.
In addition, fair to poor air quality is expected to prevail through the long term for much of the Rio Grande Valley due to agricultural burning in southeast Mexico/Yucatan and Central American wildfires all being driven north/northwestward on the persistent south to southeast flow.

MARINE
Issued at 249 AM CDT Mon May 20 2024
Today through Tuesday: Buoy 42020 reported east-southeast winds around 14 knots gusting to around 16 knots with seas slightly over 3.5 feet with a period of 7 seconds at 150 CDT/650 UTC. An initially modest pressure gradient along the Lower Texas Coast will strengthen slightly during the period, with high pressure generally in control. Light to moderate winds and low to moderate seas will become moderate to breezy winds and moderate seas during the period, and Small Craft Should Exercise Caution may be needed on Tuesday, especially for the Laguna Madre.
Tuesday night through Saturday...Light to moderate winds and generally moderate seas are expected through the weekend. A locally enhanced pressure gradient may result in a brief period of Small Craft Exercise Caution conditions each afternoon on the Laguna Madre and nearshore Gulf waters. Small Craft Exercise Caution conditions will extend to the offshore Gulf waters Wednesday through the holiday weekend due to increased winds and elevated seas.
