GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 351 Pm Cdt Thu Apr 24 2025
Synopsis for high island to the matagorda ship channel out 60 nm including galveston and matagorda bays
high pressure situated across the eastern united states will maintain onshore winds for the texas gulf coast for the remainder of the week. Seas of up to 3 feet can be expected over the nearshore waters, and up to 5 feet farther offshore, closer to 60 nm out. While isolated showers can't be entirely ruled out, that will likely be more of a concern for locations farther inland.

New AVIATION
SHORT TERM
(This evening through Friday Night)
Issued at 235 PM CDT Thu Apr 24 2025
Band of thunderstorms taking shape to our north will be making their way into the region late this afternoon and evening. General CAM consensus is that they'll make it through the northern 1/3 of the CWA then begin weakening as they make it toward the I-10 area 8-10pm...and eventually dissipate between I-10 and the coast. (Of course it is spring, so leave a bit of wiggle room in there for the finer details). Current radar upstream and guidance is showing some bowing line segments at times which indicate the potential for strong wind gusts. For the most part, suspect 30-50mph gusts are more likely...though cannot rule out some isolated pockets of severe gusts (58+mph). With PW's in the 1.7-1.9" range, localized 1-3" downpours are possible in a short time period, but speed of movement should preclude widespread flooding concerns.
After convection dissipates, we'll probably see a gradual return of late night & morning cloudiness and patchy fog. Other than potential remnant outflows on Friday, I don't see much in the way upstream to focus elevated rain chances other than the more typical diurnally driven iso-sct daytime activity. 47
LONG TERM
(Saturday through next Wednesday)
Issued at 235 PM CDT Thu Apr 24 2025
Mid to upper level ridge builds across the central CONUS this weekend, bringing drier and warmer conditions across SE TX. A few shortwaves embedded on the edge of the ridge will move close to our region, but enough subsidence and stability will help to keep these disturbances further north. With 850mb temperatures in the upper teens degC, highs temperatures into the upper 80s to low 90s can be expected Saturday through Tuesday.
The next best chance for showers and storms arrive Wednesday into Thursday time-frame. Details in timing and strength with this FROPA is still uncertain; however, models continue to show locally heavy rainfall potential across our northern counties during this period.
Therefore, continued with NBM guidance for PoPs, including up to 60 percent chance of showers/storms.

AVIATION
(00Z TAF Issuance)
Issued at 636 PM CDT Thu Apr 24 2025
Line of thunderstorms producing gusts to 20-30kt and heavy rainfall has already moved through CLL and UTS, and will be moving through CXO momentarily. This line should be weakening as it moves further south due to a loss of heating, but may stick around long enough for some isolated storms to make its way through IAH by 2z.
After then, the chance for showers and thunderstorms ends for tonight - but some isolated showers or storms may pop up again tomorrow afternoon due to daytime heating and moist southerly flow. Exactly where these storms pop up tomorrow is way too uncertain to put in the TAFs for this package.
Otherwise the main aviation concern after these storms dissipate this evening is the return of MVFR to IFR conditions tonight as CIGs drop down to around 1200-1500ft (or lower at times) with patchy fog. Clouds will scatter out by 15-17z tomorrow morning with VFR conditions persisting through the remainder of the period. Southeasterly winds will persist through the period as well dropping to 5-7kt overnight, increasing to 8-12kt during the day.

MARINE
Issued at 333 PM CDT Thu Apr 24 2025
Onshore winds between 10 and 15 knots and seas of 3 to 5 feet will prevail for the next several days. Winds will strengthen a few knots late Monday into Tuesday and seas could rise to around 6 feet Tuesday into Wednesday. Winds will slightly relax by midweek and seas will subside. After today, rain chances may be possible each day from Wednesday through the end of the upcoming work week.
Also, periods of strong rip currents are possible throughout the week.
