GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 1023 Am Cdt Mon Oct 18 2021
Synopsis for high island to matagorda ship channel out 60 nm.. A weak surface trough or low is forecast to make its way toward the northeastward from the central gulf toward the upper texas coast Tuesday night into Wednesday. Few impacts are expected other than some isolated showers or Thunderstorms and maybe some 15 knot northeast winds east of freeport. Otherwise, light winds and low seas should persist for much of the week until a more pronounced southeast flow sets up later this weekend.

AVIATION [18Z TAF Issuance].

No major changes from the previous package with winds as the main issue. East winds early this afternoon should shift to the SE for a bit before decreasing once again tonight. A more pronounced on- shore flow will be setting up for tomorrow with perhaps some FEW/ SCT clouds around 3500 feet. Otherwise, VFR. 41

PREV DISCUSSION. /Issued 403 AM CDT Mon Oct 18 2021/ .

SHORT TERM [Through Tuesday Night] . Benign weather conditions to start off the work week as sfc high pressure continues to dominate the weather pattern. Sfc high will continue to shift eastward across the Southeastern CONUS/Mid- Atlantic states during the short-term period. As the high moves east, winds will gradually transition from the northeast this morning to east-southeast this afternoon and evening. Slightly warmer conditions are expected today with highs mainly from the upper 70s to low 80s. Another quiet night is on tap for the region; but east to southeasterly flow at the sfc and partly cloudy skies will keep readings on the mild side, at least over the coastal zones.

The influence of the sfc high remains over the region by Tuesday. However, southeasterly flow will continue to bring more Gulf moisture throughout the day. Daytime heating and pockets of PWATS around 1-1.5 inches along the islands and over the Gulf waters may allow for some spotty showers. A weak sfc low could develop over the western Gulf, making its way towards the Upper TX coast Tuesday night into Wednesday. In fact, deterministic and Hi-res models suggest a broad area of theta-e advection and an increase in low to mid-level instability ahead of this system. Therefore, have increased cloud coverage and introduced low precipitation chances across the Gulf waters and the coastal zones during this time-frame. 05

LONG TERM [Wednesday Through Monday] . The aforementioned disturbance, rooted at the H85 level with possible weak sfc reflection/low should make its way inland across the upper Tx coast or sw La Wednesday. Appears fairly insignificant for the most part locally . maybe some isolated shra/tstms offshore and east of I-45. (Highest moisture levels will be displaced well to the east - across the eastern half of La into the Mississippi Valley).

Otherwise, a fairly uneventful remainder of the week is expected. PW's vary between 0.75-1.40" most of the week depending on the day and model of choice. Can't completely rule out a rogue afternoon shower or tstm, but chances for any individual location should be quite low Thursday into Saturday. Flow aloft should be mostly zonal and don't have much hope the weak frontal boundary in north Tx makes it this far south. Look for lows in the 60s inland & low 70s at the coast. Highs will be in the 80s.

A more pronounced onshore flow sets up later this weekend into early next week which should bring some more cloud cover, higher RH's and iso-sct diurnally driven precip. Extended models don't show any more significant fronts on the horizon until maybe the 27th at the earliest. 47

MARINE . Light wind & low seas regime for most of the work week. Exception might be Tue night into Wed when a weak surface trof or low tracks inland toward the eastern portions of the upper Tx coast. Even then, not expecting much more than 15kt winds and some isolated showers or thunderstorms. Otherwise, weak gradient will favor landbreeze/seabreeze circulations for a good portion of the week. A more predominate southeast wind sets up later this weekend with a corresponding bump in seas. 47
