PREV DISCUSSION. /issued 600 PM CDT Mon Jul 13 2020/

DISCUSSION . Updated for latest aviation discussion below.

AVIATION . VFR conditions currently at the TAF sites. BRO conditions confirmed visually. High pressure over the Gulf will support persistent southeast breezes, strengthening during the day. Clear skies expected through tonight, but few to scattered coastal low clouds may develop early Tuesday morning through mid morning, with very brief broken conditions possible. Confidence not high enough to add mention of MVFR to the current TAF set, however.

PREV DISCUSSION . /issued 239 PM CDT Mon Jul 13 2020/

SHORT TERM (Now through Tuesday Night): Still monitoring temperatures and dewpoint temperatures across the region early this afternoon. A few locations may approach their daily record highs later this afternoon. However, most locations are expected to remain below Heat Advisory criteria through sunset. Nevertheless, current temperatures (as of 2 PM CDT) and/or heat indices range between 100 and 108 degrees across the CWA, hot enough to cause heat exhaustion. Be sure to wear light colored clothing and drink plenty of water if outdoors for a prolonged period of time through the remainder of the afternoon.

Mid/upper-level ridging over west/northwest Texas will continue to influence hot and dry conditions across deep South Texas through the short-term. A slight "cooling trend" will begin tomorrow as a weakening on the southern edge of the ridge works its way over northeast Mexico and South Texas. Afternoon high temperatures tomorrow are expected to be about 2-3 degrees cooler than today, which should keep temperatures and heat indices below Heat Advisory criteria. Once again, highs tomorrow are expected to reach the upper 90s (east) to mid 100s (west), hot enough to cause heat-related illnesses if proper hydration protocols are not taken. Low temperatures will remain abnormally warm over the next few nights, mid-upper 70s and lower 80s in spots. Breezy and gusty winds are expected to continue tomorrow afternoon as thermal troughing and deepening low pressure inland interacts with high pressure across the Gulf of Mexico. Strongest breezes will generally stay along the coast during the late-morning/ afternoon and early evening hours; gusts may reach up to 30 mph in some areas tomorrow.

LONG TERM (Wednesday through Monday): 500mb subtropical ridge across the state Wednesday will lift slowly northward Thursday into Friday as a 500mb inverted trough develops across the central Gulf of Mexico Thursday and moves westward into the western Gulf on Friday. This feature will continue to move west across northeast Mexico and the Rio Grande Valley Saturday. This will provide an increase in moisture across the CWA through the weekend into early next week. Will mention a slight chance of showers and thunderstorms across the coastal sections of deep south Texas mainly for isolated seabreeze convection Otherwise. hot and humid conditions will continue Wednesday through Monday with heat index values approaching heat advisory conditions across the upper portions of the Rio Grande Valley Wednesday through Friday.

MARINE (Now through Tuesday Night): Buoy 42020 reported south winds around 14 knots gusting to around 18 knots with seas around 3 feet with a period of 5 seconds at 1340 CDT/1840 UTC. Very little changes were made to previous marine discussion. High pressure will remain in control across Gulf of Mexico. Low pressure will deepen across the Plains late tonight and into tomorrow, strengthening the PGF and increasing SSE winds along the lower Texas coast through the short term period. A Small Craft Advisory may be needed for the Laguna Madre and possibly the near-shore Gulf waters tomorrow, with SCEC conditions expected over the Gulf waters. Gulf seas remain generally low to moderate into Tuesday night with gusty winds possible across northern Gulf waters into Wednesday morning.

Wednesday through Saturday . Moderate south to southeast winds will prevail across the coastal waters Wednesday with surface high pressure across the eastern Gulf of Mexico. The pressure gradient will weaken across the western Gulf Thursday. Light to moderate southeast winds will prevail across the lower Texas coast Thursday through Saturday as the pressure gradient remains weak across the coastal waters.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
