New AVIATION

SHORT TERM
(Tonight through Tuesday night)
Issued at 218 PM CDT Mon Apr 15 2024

Key Points:

* A Wind Advisory remains in effect till 8 PM CDT tonight as an enhanced low level jet and tightened pressure gradient are resulting in strong southeasterly winds of 20 to 25 mph with gusts up to 40 mph.

* A Rip Current Statement remains in effect through Tuesday evening due to dangerous rip currents resulting from enhanced winds and elevated seas.

Throughout the short term, the region will remain within a zonal upper level flow of a subtropical ridge aloft and a southwesterly flow at mid-levels as a 500 mb high pressure remains, overall, stationary over the southwestern portion of the Gulf of Mexico. At lower levels, a low level jet (LLJ) will continue to increase throughout the evening, peak overnight and then gradually weaken as it moves offshore late tonight and through tomorrow morning.

At the surface, strong and gusty south-southeasterly winds, resulting from winds being brought down from the LLJ, via boundary layer mixing heights and a tightened pressure gradient, will continue this afternoon and into the evening. A Wind Advisory remains in effect for southern Hidalgo, Cameron, Willacy and Kenedy Counties through 8 PM CDT tonight for strong southeasterly winds of 20 to 25 mph with gusts up to 40 mph. As mixing heights lower later this evening, winds will ease slightly, but will continue to be windy and gusty through tonight as the pressure gradient remains tightened. Overnight lows will be in the lower 70s with mid 70s over the Rio Grande Plains, RGV and coastal areas.

Late tonight and through sunrise tomorrow, the LLJ will begin transitioning offshore to the northeast and begin to weaken through the day tomorrow. However, winds are expected to continue to be gusty through at least midday tomorrow, particularly over the middle and lower RGV as rising mixing heights mix down enhanced LLJ winds as the LLJ departs. Following, winds will diminish for much of the CWA by midday, though still remaining breezy closer to the coast, and temperatures will soar into the low to mid 90s across Deep South Texas with upper 90s across the Rio Grande Plains and 80s across coastal areas.

Tomorrow night, southeasterly winds will be generally light across the CWA and overnight temperatures will be nearly the same as tonight, but with mid 70s extending into the southern Ranchlands.

LONG TERM
(Wednesday through next Monday)
Issued at 218 PM CDT Mon Apr 15 2024

The long-term does not have that much to offer until next weekend when convection trends increase with the approach of cold front.
In the meantime, a general W-SW flow aloft with a few embedded disturbances may provide isolated convection chances midweek favoring the western third of the County Warning Area (CWA).
Expect a seasonal weather regime with modest southerly flow maintaining near to slightly above normal temperatures and average moisture values. Models continue to show a weakening upper trough approaching NE Mexico Wednesday night and passing over South Texas Thursday. Modest instability and moisture depth may allow for isolated convection over the western counties during this time period. Models do not indicate any sea breeze activity at this time but with GFS moisture depth increasing can not rule out an isolated shower or two along the seabreeze boundary during peak heating hours each afternoon with chances only 5-10%.

Latest model trends are pinpointing next Saturday and/or Sunday with a better chance of convection especially with a cold front approaching Saturday night and potentially moving through Sunday.
It's a long way out, but with cape values exceeding 1500 j/kg, increasing lapse rates and a cold front in the vicinity some convection could be strong. Otherwise, temperatures stay above normal Friday and Saturday before showing a downward trend next Sunday and Monday as the front traverses the CWA

AVIATION
(00Z TAFS)
Issued at 617 PM CDT Mon Apr 15 2024

Southeasterly winds will continue to be breezy through tonight across all aerodromes. Wind gusts will continue to between 25 and kts through the overnight hours. VFR conditions will fall to MVFR (already has at BRO) this evening and overnight. Will likely see some wavering this evening between MVFR and VFR, especially at BRO and HRL. VFR conditions will return to MFE early Tuesday morning, and by midday at HRL and BRO.

MARINE
Issued at 218 PM CDT Mon Apr 15 2024

Tonight through Tuesday night...A Small Craft Advisory remains in effect for the Laguna Madre till 8 PM CDT tonight as boundary layer mixing heights continue to mix down strong winds from an enhanced low level jet within a tightened pressure gradient, resulting in strong and gusty southeasterly winds and adverse marine conditions.
Small Craft Advisories continue till noon CDT Tuesday for the nearshore (0-20 nm) and offshore (20-60 nm) Gulf Waters as the effects from the tightened pressure gradient and departing low level jet persist. Gradual improvement is expected tomorrow afternoon and tomorrow night as winds diminish and seas gradually lower.

(Wednesday through Monday): Latest model projections show a moderate pressure gradient for the Western Gulf of Mexico and the lower Texas coast for the middle and half of the week. The pressure gradient between surface ridge over the Gulf and low pressure over the Central and Northern Plains to maintain a moderate southerly Wednesday and Thursday. A cold front is shown to move over Central Texas Friday slowing its forward progress settling over Southcentral Texas Saturday and potentially moving offshore the lower Texas coast Sunday. Southeast winds veer east and weaken Friday and Saturday with north winds increasing as the front moves south sometime Sunday. The cold front may bring about an increase chance of thunderstorms next weekend.
