New SHORT TERM, LONG TERM, MARINE

SHORT TERM
(Tonight through Saturday night)
Issued at 228 PM CDT Fri May 3 2024

The combination of moist, low-level air, daytime heating, and mid to upper level energy could still support some convection to the west over neighboring Mexico late this afternoon through evening.
Isolated to scattered showers and thunderstorms could potentially drift into Zapata, and possibly Starr and Jim Hogg counties later this afternoon and evening. SPC has placed the aforementioned areas in a marginal severe thunderstorm outlook area, with the remainder of the CWA in a general thunderstorm outlook area. The main threats would be large hail and strong to severe wind gusts.

Otherwise, increasing low level moisture and light winds tonight may support patchy light fog, mainly across the Northern Ranchlands and near/over marine areas. With a weak cold front staying north of the area tomorrow, the CWA is not in a thunderstorm outlook area for day 2.

Additionally, above normal temperatures (a few degrees above average) will continue through the short-term with highs generally ranging from the lower to mid 90s, except for the 80s near the coast, Saturday. Overnight temperatures will be warm with lows mainly in the mid 70s. Southeast winds will remain moderate to breezy.

Moderate seas will sustain a moderate risk of rip currents at the local beaches through Saturday night.

LONG TERM
(Sunday through next Friday)
Issued at 228 PM CDT Fri May 3 2024

The main event for the long term forecast period continues to be the above normal temperatures and the potential for some Heat Advisories to be issued next week. With the continued surface flow of southerly winds bring in more warm air to the region temperatures are expected to continue to rise. With the wind possibly having a southwesterly component to it as well during the period, that would allow for some dry, but even warmer air to move into the region. With the expected cloud coverage looking rather sparse as well during the upcoming work week, the incoming solar radiation will allow for even more heating during the day. While borderline for Tuesday, Wednesday and Thursday seem more likely days that will require Heat Advisories issued due the combination of the hot temperatures and very humid environment. High temperatures are expected to be in the triple digits for most of the area, with areas along the coast in the lower 90s.

With an almost consistent zonal flow pattern aloft and a lack of any real forcing in the atmosphere, the long term forecast period is expected to be rain free. With that, there is not much expected to be in the form of relief from the heat expect maybe a bit of a breezy.

AVIATION
(18Z TAFS)
Issued at 1231 PM CDT Fri May 3 2024

TAF conditions are VFR at the sites as low clouds have scattered out. Still have ceilings above 3 kft, however. High pressure controls the Gulf, with lower pressure to the west, sustaining the seasonal moderate southeast winds across the region. A few storms could be possible upstream toward Laredo this evening, but the lower and even mid RGV, including the TAF sites, should avoid convection. A familiar pattern will occur this evening as ceilings lower to MVFR overnight through Saturday morning. Southeast winds will decrease to light overnight, strengthening to moderate and breezy on Saturday. Light, patchy fog could develop at the TAF sites overnight, but visibility limitations should be no worse than MVFR ceilings.

MARINE
Issued at 228 PM CDT Fri May 3 2024

Tonight through Saturday night...Moderate to fresh southeast winds and moderate to sometimes higher seas will prevail along the lower Texas Coast. Small craft should exercise caution conditions may occur at times.

Sunday through Next Friday..Generally light to moderate winds and moderate seas will be in play through next Friday. This will lead to extended periods of Small Craft Exercise Caution as winds increase with the tight pressure gradient over the Lower Texas Coast. While rougher seas are also possible around Monday, requiring a low-end Small Craft Advisory.
