Synopsis for the middle texas coastal waters.. Weak to moderate winds expected tonight through Friday night. Isolated to scattered showers and Thunderstorms are expected through the day tomorrow. Isolated showers and Thunderstorms will continue as we head into the weekend along with a weak to moderate onshore flow. We may see a lull in activity on Sunday before rain chances return next week as a cold front moves across the state. Look for onshore flow to strengthen to more moderate levels by mid week in response to the approaching upper level disturbance.

AVIATION.

Primarily VFR conditions are expected through the period, but tempo MVFR toward morning for VCT and ALI with the potential for moderate fog or low clouds filling in. These conditions should clear by mid-morning. Showers and thunderstorms will be possible once again with the sea breeze. The best chance would be for VCT where have mention of showers for a few hours mid-day. CRP and ALI also have a chance to see convection, but chances are too small to include in TAF at this time.

PREV DISCUSSION. /Issued 325 PM CDT Thu Jul 29 2021/

SHORT TERM (Tonight through Friday Night) .

Current Doppler Radar reflectivity shows isolated showers and thunderstorms popping up along the Coastal Bend. Expect showers and storms to continue to pop up through the afternoon, decreasing in coverage with the loss of daytime heating. Patchy fog will be possible tonight over the Coastal Plains as skies remain mostly clear with winds light and variable. Lows will be in the 70s to near 80 along the coast. Gulf moisture will be more enhanced tomorrow with PWATs above 2.0". Though mid-upper level support remains scarce due to ridging, scattered showers and thunderstorms are expected to develop in the afternoon along the sea breeze. With winds continuing to be weak, tropical funnels cannot be ruled out. Precipitation will taper off tomorrow evening leaving mostly clear to partly cloudy skies.

Highs tomorrow will generally be in the 90s with a few spots out west approaching 100 degrees. Heat indices of 105-109 are expected for most of South Texas. Lows tomorrow night will be in the 70s.

LONG TERM (Saturday through Thursday) .

We start out the long term under the influence of an upper level ridge. However, the ridge will start to shift northwest over the weekend as a weak inverted trough takes shape across the Southern Gulf. Isolated showers and thunderstorms will be possible on Saturday, mainly along the sea breeze as low level moisture remains plentiful. Kept chances on the low end on Sunday as models continue to show some mid level drying and a strengthening cap around H85.

Our pattern begins to shift next week as a trough dives south across the Midwest towards the southeast. An associated cold front will progress south across the state Monday into Tuesday before stalling to our north. Moisture will be on the rise early next week as a ~20- 25 knot H9 LLJ kicks in with PWATs ramping up to ~2". Models have come into better agreement with this boundary stalling across Central Texas Tuesday night before a secondary shortwave rounding the base of the trough forces it our way by late in the work week. Regardless of the timing and position, we can expect an increase in rain chances through the week. Exact timing details and rainfall totals will be worked out over the next few days.

Hot and humid conditions will continue with highs in the low 90s along the coast to around 100 degrees out west. Heat indices will hover around the 105-109 range each afternoon. It's possible a few locations top 110 at times as moisture picks up heading into next week. As expected, nights will be warm and muggy.

MARINE .

Weak to moderate winds expected tonight through Friday night. Isolated to scattered showers and thunderstorms are expected through the day tomorrow. Isolated showers and thunderstorms will continue as we head into the weekend along with a weak to moderate onshore flow. We may see a lull in activity on Sunday before rain chances return next week as a cold front moves across the state. Look for onshore flow to strengthen to more moderate levels by mid week in response to the approaching upper level disturbance.
