Synopsis for high island to matagorda ship channel out 60 nm.. Onshore winds will prevail this weekend ahead of a strong cold front that will move into the coastal waters Monday afternoon. Strong northerly winds, with gusts possibly close to gale force in the outer waters, can be expected Monday night in the wake of the front. Winds and seas should begin subsiding late Tuesday into midweek. A reinforcing but much weaker cold front is forecast to move into the waters Thursday night or Friday.

Area Forecast Discussion National Weather Service Houston/Galveston TX 1146 PM CDT Sat Sep 26 2020

AVIATION [06Z TAF Issuance].

Compared to 24 hours ago, winds across the area are a few mph higher. This increased in wind speed may inhibit fog development through the next few hours. However, dewpoint depressions across our usual trouble spots (LBX, CXO) are beginning to shrink, so have continued the 6SM with BR for some of our sites into the early morning. MVFR CIGS will also by a concern through sunrise for most of the area. The southerly flow will be strengthening in the afternoon with sustained winds of 10 to 15 mph through the afternoon with isolated wind gusts up to 20 mph. Elevated winds appear to be the strongest to the north, so have included a gust group in the CLL TAF in the afternoon. While isolated gusts will be possible at all the sites, these should be infrequent enough to not include in the TAF. No showers or thunderstorms are expecting through the period.

PREV DISCUSSION /Issued 631 PM CDT Sat Sep 26 2020/.

SHORT TERM [Rest of Today through Sunday Afternoon].

A rather benign weather pattern will continue across SE Texas through the short term period. For the rest of the day today, expect partly to variably cloudy skies with southerly winds at 5 to 10 MPH. Temperatures this afternoon will be a few degrees warmer than yesterday, peaking in the mid to upper 80s areawide. Skies are expected to clear out in the evening, however, cloudiness is expected to return during the overnight and early Sunday morning hours. Areas of patchy fog are expected to develop once again overnight into early Sunday morning across portions of SE Texas. Lows tonight will be in the upper 60s to low 70s along areas north of I-10 and in the low to mid 70s along areas south of I-10. Winds will be increasing Sunday morning, which could help lift and scatter out the fog quicker than today, or may even not allow the fog to develop at all for a few locations. If fog does develop tonight, expect it to lift and clear out by mid morning. With a more pronounced southerly wind flow, we may have isolated showers moving across the local waters from the Gulf Sunday morning and may reach the coastal locations from time to time. However, confidence of this occurring is low and thus kept PoPs at 10% for the waters and coastal locations. High temperatures Sunday afternoon will increase into the upper 80s and low 90s. An increase in low level moisture will also increase dewpoints into the low 70s Sunday afternoon. 24

LONG TERM [Sunday Night Through Saturday].

Late Sunday night through early Monday morning, look for increasing chances of northern county showers and possible thunderstorms, probably beginning shortly before sunrise as a strong cold front enters the area from the north. This front will sweep through Southeast Texas and could very well be off the coast by around or shortly after noon. With the fast movement of the front, still anticipating rainfall amounts to average 1/2 inch or less. With winds shifting to the north behind the front (becoming breezy inland and breezy/windy at the coast), look for a decreasing trend in temperatures during the afternoon. Cool nights and mild days (lows mainly in the 50s inland and in the 60s at the beaches and highs in the 70s/80s) along with low humidities and no rain can be expected for the remainder of the week as a western U.S. ridge and an eastern U.S. trof become established in the mid/upper levels. This pattern will allow for a Thursday-Friday reinforcing (but much weaker) cold front to move through the area. Currently, this pattern looks to hold into the weekend and on into the start of next week. Some gradual warming can be expected as winds come back around to the south and southeast, but moisture levels look to be too low for any rain development. 42

MARINE.

Light to occasionally moderate onshore winds will continue through Sunday night. A strong cold front will move into and through the coastal waters late Monday morning through Monday afternoon. Winds will shift to the north behind the front and strengthen, and small craft advisories will be needed for the development of the strong winds and rough bay waters/seas. Wind gusts could possibly increase to near gale force Monday night. Decreasing winds and seas can be expected late Tuesday into midweek as high pressure builds into the area and the gradient weakens. A reinforcing and much weaker front is still anticipated to move into the waters Thursday or Friday. The offshore flow behind this front will quickly swing back around to onshore over the weekend. 42
