New AVIATION
SHORT TERM
(Today through Saturday)
Issued at 344 AM CDT Fri Apr 26 2024
An established broad mid-level trough covering the western half of the nation with a ridge building from the NE Gulf of Mexico north along the eastern third CONUS looks to maintain a tight pressure gradient over Deep South Texas today and Saturday. Deepening surface pressure over the Central Plains supports a low level jet (LLJ) of 30-40kts today with another lee side low developing tonight and Saturday strengthening the LLJ to 45 knots. A Wind Advisory has been issued for the Lower RGV 11 AM-7 PM Today with another probable wind advisory for Saturday with lager areal coverage as a broader and slightly stronger LLJ is shown by the latest model suite.
The breezy to windy southerly winds maintains a steady flow of Gulf moisture and warm to hot temperatures. Expect above normal highs and lows the next two days with heat indices having a medium to high (30- 70%) probability of exceeding 100 degrees Saturday. A few light showers are possible early this morning with a weak disturbance passing overhead, otherwise moisture depth is limited and forcing of the low level moisture today or tomorrow is absent with a cold front and dryline remaining well north and west of the South Texas respectively.
Along the coast the strong southerly winds maintain rough surf and a high risk of rip current.
LONG TERM
(Saturday night through Thursday)
Issued at 344 AM CDT Fri Apr 26 2024
The tight pressure gradient continues to remain a factor in the long term forecast for Deep South Texas and the Rio Grande Valley at the start, but not expecting Wind Advisories to be needed as the current forecasted winds are in the range of 20-25 mph. As we move into the work week, an upper-level trough will into Northern Texas and move eastward, which will result in a zonal flow like pattern for a few days with a weak mid-level ridge sliding over the area by Wednesday.
This mid-level ridge is not expected to stay over the area for long, as it will move eastward allowing for a zonal flow aloft to return to by the end of the work week.
Meanwhile, at the surface, southerly to southeasterly flow is expected to continue, which will funnel more warm, humid air to the region. While the moisture advection does remain constant, the opportunities for rain appear do not look very promising. The greatest opportunity in the long term forecast period appears to be late Monday into Tuesday. A series of shortwaves will be moving through the upper levels that could help the development of convection along the Sierra Madre Mountains. Some of these showers and thunderstorms could make it to Deep South Texas and the Rio Grande Valley before they dissipate. However, rain chances remain in the range of 20 to 30 percent, as these types of showers and thunderstorms often do collapse once they move away from the mountains.

(12Z TAFS)
Issued at 549 AM CDT Fri Apr 26 2024
MVFR ceilings persist through mid-late morning with VFR SCT-BKN ceilings for the afternoon hours. Expect the lower ceilings to return a few hours after sunset. Southerly winds beginning to increase this morning are likely to gusts 25-35 knots between 15 to 02Z. Breezy to windy conditions continue overnight as the strong pressure gradient persist.
MARINE
Issued at 344 AM CDT Fri Apr 26 2024
Today through Saturday: An already strong pressure gradient is expected to strengthen tonight as a series of low pressure areas extend from the South to the Central Plains. No let up in the strong southerly winds with seas continuing to build through Saturday.
Small Craft advisories already in place to are likely to be extended tonight and Saturday.
saturday Night through Thursday...Hazardous conditions to start off on Saturday night due the elevated winds and seas from the tight pressure gradient. Improvements in the marine conditions will start to occur on Sunday afternoon, but Small Craft Advisories might be needed through the weekend and into Monday.
Light to moderate winds with moderate seas through Thursday, but there is a chance of Small Craft Exercise Caution for needed during the later part of the the period.
