Marine Weather and Tide Forecast for Richmond, TX

LONG TERM
(Friday through Tuesday)
Issued at 100 AM CDT Wed May 21 2025

Southeast Texas will start the long term period with sunny to partly cloudy skies and highs generally in the lower to mid 90s inland and the upper 80s to lower 90s along the coasts Friday and Saturday as the mid-level ridge dominates the local weather pattern.

On Sunday, models continue to suggest PWs of 1.5" to 1.8" on Sunday, while upper-level ridge weakens and a few ripples in the flow pass overhead. Some models hint at Sfc CAPE of around 3,000 J/kg in and around the Brazos Valley and Piney Woods region, while the rest of the inland areas are closer to the 2,000 J/kg level for the late afternoon to early evening period. It also seems as a cold front could be on its way towards Southeast TX, which would provide some lift. This all could lead to showers and isolated thunderstorms for this timeframe, however, we may still have some influence from the mid-level ridge that day. Thus, I believe the locations with the best opportunity will be in that Brazos Valley/Piney Woods region.

The better set up for showers and thunderstorms still looks to occur Monday into Tuesday as the ridge weakens in response to an upper level trough moving across the Southern Plains. We could also have a few disturbances passing overhead as well the cold front passing through. Tonight's model runs look more in tune with bringing the cold front with highs possibly lowering into the upper 80s on Monday and the lower to upper 80s on Tuesday. After all the hot days we have had lately, I really hope we can get this "cool" chance for a more spring like day early next week.

AVIATION
(12Z TAF Issuance)
Issued at 619 AM CDT Wed May 21 2025

Generally VFR conditions will prevail through the day today with BKN to OVC CIGs around 4000-6000ft this morning that will scatter out by the late morning. A stalled boundary in the coastal waters this morning will meander closer to GLS/LBX over the next few hours leading to scattered showers and isolated thunderstorms.
Can't out-rule a stray shower making it up to around HOU/SGR by the afternoon, but chances are too low to put in the TAF.

Winds (around 6-10kt) will gradually shift through the day: northeasterly winds this morning, easterly this afternoon, then southeasterly by this evening.

MVFR conditions will develop across the area between 07-09z with CIGs around 1500ft and patchy fog. There could be some temporary periods of IFR conditions at UTS and CXO near daybreak Thursday.

Issued at 100 AM CDT Wed May 21 2025

Light VRB winds expected tonight as a weak cold front moves over the waters. East winds and seas of 2-4 feet are expected on Wednesday. Onshore flow returns late Wednesday and is expected to prevail through early next week. Winds could increase to moderate at times during the weekend and may lead to Caution flags as well as strong rip currents along the Gulf facing beaches. Chance for showers and thunderstorms may return late Sunday or early Monday and continue into next Tuesday as a cold front moves across Southeast TX.
