GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 858 Pm Cst Wed Nov 29 2023
Synopsis for high island to the matagorda ship channel out 60 nm including galveston and matagorda bays
primary concern will be the increased onshore winds and building seas late tonight and Thursday ahead of a strong weather system moving across the southern plains. Southeast and south winds in the 20 to 30 knot range are anticipated along with seas of 6 to 9 feet nearshore and 10 to 14 feet offshore. This system will also bring widespread showers and Thunderstorms Thursday, some of which could be strong. Periods of unsettled should persist through the day Friday as the front stalls offshore.

New UPDATE
UPDATE
Issued at 948 PM CST Wed Nov 29 2023
Incoming 00z HRRR members continue to point toward a conditional risk of severe storms Thursday with a high shear/low CAPE environment in place. Limiting factor for widespread severe storms would be overall instability and things lining up just right.
Looks like there will be some elevated shra/tstms around the region heading into the morning rush hour. Though only a limited amount of new model data is in and am somewhat hesitant to speculate without a full dataset, one thing we might look for is a secondary round of storms to develop across w/wsw parts of the western CWA heading into mid morning...eventually tracking ewd during the late morning and afternoon. This batch should theoretically have a slightly better chance of tapping into whatever llvl instability presents itself. A few tornadoes remain the primary concern. Though storm motions will be on the higher end, repeated downpours with rates >2"/hr are a distinct possibility. On average, 1-2" amounts are forecast south of I-69/US-59..with some of the incoming guidance suggesting the potential for localized higher swaths along/south of I-10 (particularly around Galveston Bay area). Street flooding is possible where heavy rain falls in a short time period.
Ongoing forecast is pretty much on track and just some fairly insignificant tweaks were made for the update. One thing to note...portions of Southeast Texas are currently outlooked for an enhanced risk of severe storms Thursday. Just because your particular location might not be situated right within this particular enhanced risk area does not mean significant weather will not, or cannot, occur. Residents all the way down to the coast should keep an eye on the latest forecast conditions during the day Thursday. 47
SHORT TERM
(This evening through Thursday Night)
Issued at 224 PM CST Wed Nov 29 2023
A mid/upper trough will eject northeastward across Texas and into the Plains Thursday and Thursday night. The atmosphere will destabilize and moisten ahead of this feature, leading to widespread showers and thunderstorms beginning late tonight and Thursday morning.
Rounds of showers and storms are expected all day Thursday and continuing into Thursday evening for eastern areas.
There is a slight and enhanced risk of severe thunderstorms (Levels 2 and 3 of 5) for SE Texas tomorrow. This threat is likely to begin in the morning, persist through the afternoon, and shift east of the area by late evening. The main concern is isolated tornadoes, but strong wind gusts and large hail are a possibility as well. It should be noted that there is uncertainty concerning the degree of instability given that surface heating is likely to be limited due to cloud cover and widespread convection. The wind shear is significant though, and therefore warrants the severe thunderstorm/tornado risk.
Although showers and thunderstorms are expected to move quickly enough to limit the flooding potential, some cell training, especially across central and eastern areas, could result is localized flooding.
Another concern for tomorrow will be increased south to southeast winds ahead of this strengthening system. Winds of 15-25 mph with higher gusts can be expected areawide tomorrow afternoon.

LONG TERM
(Friday through next Tuesday)
Issued at 138 PM CST Wed Nov 29 2023
Not many changes this afternoon from the overnight forecast for the end of this week into early next. Primary focus will be Friday through the weekend with some uncertainty on rain/shower chances as the cold front hangs up over the nwrn Gulf after pushing offshore late Thursday. For now will keep chance or slight chance wording for rain showers near the coast each day, with lower or no PoPs farther inland. Other than some lingering clouds and rain chances near the coast as mentioned, we will see general improvement in the overall weather starting this weekend with drier weather for all areas by early next week. All in all, rather seasonal temperatures can be expected each day with highs in the 60s to lower 70s each day.

BKN cirrus/VFR decks are expected early tonight with light to moderate SE winds prevailing across the region. MVFR CIGS begin to fill in overnight as light showers develop from west to east.
CIGS drop to IFR levels Thursday morning with gusty conditions developing as a 35-40 knot LLJ settles in around 2000 ft. Numerous thunderstorms are expected late Thursday morning through the afternoon. Locally heavy rainfall with these storms may result in low visibility and LIFR CIGS at times. These storms will also be capable of producing severe weather.
Rain chances decrease Thursday evening with winds shifting S/SW ahead of an approaching cold front. Lingering showers remain possible along and ahead of this front.

Primary concern will be the increased winds tomorrow ahead of a strong weather system moving across the southern plains. This will bring strong onshore winds near Gale force in the offshore, with caution or advisory criteria for the nearshore and bays. Seas will also build through the day with seas of 6 to 9 feet nearshore and 10 to 14 feet offshore. This system will also bring widespread showers and thunderstorms Thursday, which will persist through the day Friday as the front stalls offshore.
