Synopsis for high island to matagorda ship channel out 60 nm.. Light winds and low seas are anticipated the next couple days. A more prevalent southerly flow should set up Sunday into Monday in advance of a cold front that is forecast to push off the coast late Tuesday night. With cooler air moving across warmer waters, expect moderate north and northeast winds in its wake.

AVIATION [12Z TAF Issuance].
Patchy fog will dissipate shortly after sunrise this morning. Afternoon showers and thunderstorms possible, but confidence is low on exact location of these showers. Therefore, VCSH/VCTS for now, but expect short fused TEMPOs should any of this activity impact an airport. Coastal showers possible overnight and early tomorrow morning, but very isolated so did not include VCSH for now. Patchy fog possible again overnight tonight. KBL
PREV DISCUSSION /Issued 445 AM CDT Sat Sep 18 2021/.
SHORT TERM [Today Through Sunday Night].
With PWs climbing to 1.7 to 1.8 today and a mid level low overhead acting as a forcing mechanism, rain chances will peak at 40-50% this afternoon with daytime heating. Forecast soundings show the 850 mb cap slowly eroding throughout the day and sfc temps able to reach convective temps of the lower 90s by mid afternoon. After sunset, some isolated showers may remain throughout the night, especially along the coast as weakness aloft remains overhead and begins to push east. By Sunday morning, weakness aloft is centered over the TX/LA border, and hi res models hint at coastal showers early in the morning beginning to push onshore. Tomorrow is a similar setup, but PWs will climb slightly higher for central and southern counties and reach 1.8 to 1.9 inches. Mid level low continues to push off towards the east and will be centered in LA by the afternoon, so most convective activity is focused along the coast and for eastern counties where lowest 500 mb heights reside.
Regarding temperatures, daytime highs should peak in the lower 90s for our western counties due to less cloud cover and everywhere else will reach the upper 80s to near 90. As skies clear out overnight, overnight lows will reach the lower to mid-70s for most areas and near 70 for northern counties and rural sites. KBL
LONG TERM [Monday Through Saturday]. Cold front moving through the Southern Plains Monday morning and should be crossing the Red River early Tuesday morning. Across SETX Monday the upper trough axis will be filling but will still have some deeper moisture over the southeastern counties and a warm profile above 500mb inhibiting deeper convection. Will keep slight chances going generally southeast of the I-69 corridor but that may be overdoing rain chances. Tuesday scattered showers and thunderstorms will be possible as upper levels start to cool down and the front approaches. By late afternoon 2000 j/kg should be present with minimal capping and temperatures reaching the lower to mid 90s though winds should be light. As the front moves into the area (a little faster than previous runs) overnight early Wednesday will see rain chances ramp up as the front moves through the region. The storms should be pushing off the coast by around 8 am Wednesday (if not sooner) . coverage should be good given the moisture present and frontal forcing. Drying behind the front looks very substantial and will usher in quiet weather with much cooler temperatures especially across the northern 1/2 of the region. High temperatures Wednesday and Thursday should be limited to lower to mid 80s and overnight lows in the mid to upper 50s north and even mid 60s to around 70 on the coast! Min temperatures start to rebound Friday night and continues to rise Saturday morning. 45
MARINE. Fairly light wind regime through Sunday night with the offshore flow being replaced by slightly stronger onshore flow Sunday night and Monday. Seas building Sunday night and Monday before winds relax Tuesday. The main issue for the marine will be the arrival of the cold front with storms and then the stout offshore flow. Early Wednesday morning and mid morning will be the start of it with the storms and winds cranking up. Winds increase to around 20 knots and gusty and seas rise to 5-8 feet. Winds should be relaxing Wednesday night/Thursday as high pressure settles into SETX/LA. 45
