Synopsis for high island to the matagorda ship channel out 60 nm including galveston and matagorda bays
moderate onshore winds and elevated seas will prevail through Monday resulting in small craft needing to exercise caution at times. Scattered showers and storms, some potentially strong, will be sagging southward and impact the waters for the remainder of the day and evening. Increased flows are anticipated near the san jacinto river and along the intercoastal water way as flood waters enter the bays over the next several days. Navigation will be difficult to hazardous in and near creeks, streams and rivers discharging into the upper texas waters and bays.

SHORT TERM
(This evening through Monday Night)
Issued at 242 PM CDT Sun May 5 2024
Flood Watch will expire at 7pm. More below.
Tail end of last night's disturbance left an east-west boundary meandering around I-10 that has been the focus for shra/tstm activity today. This precip, in addition to the cells that are popping up across northern parts of the CWA (who have become unstable following some sunshine), should be in the waning stages this evening as we lose heating.
Tonight, we're not expecting much in the way of precip, but with wet ground and light winds, we'll probably see some patchy fog development.
On Monday, look for a continued waa regime with se winds off the Gulf. Guidance shows some ill defined, weak impulses embedded in the zonal flow aloft moving across northern parts of the CWA during the day. But nothing of significance is noted on satellite pix. Moisture levels will be a bit lower tomorrow too with PW's ~1.5" vs 2" today. As such, one would anticipate some iso-sct showers and maybe a tstm or two, but overall coverage and intensity should not be enough to generate new flooding and likely wouldn't cause ongoing flooding to get worse. As such, am planning to let the Flood Watch expire at 7pm.
Despite its expiration...it's important to remain out of floodwaters, don't drive around barricaded roads, and follow recommendations from your local emergency management officials. 47
LONG TERM
(Tuesday through next Saturday)
Issued at 242 PM CDT Sun May 5 2024
Tuesday-Thursday looks increasingly hot. Llvl winds transition to the sw and H85 temps climb to 21-24C. This will essentially cap the atmosphere and put an end to rain chances. With daytime temps in the 90s, dewpoints in the 70s and a wet ground...it'll be quite uncomfortable outside with heat index values in the 100-104 range. Anyone doing recovery work outside should keep this in mind and not overdo things.
A cold front will sag southward across the Red River late Wednesday and into north Tx. It probably won't be til Thursday night when it gets a secondary push from high pressure moving down the Rockies to move all the way through SE Tx. Cannot rule out some sct tsra ahead of this boundary, but will be highly dependent on the capping situation at that time.
The front, and increased Gulf moisture moves briefly back inland early Saturday as a warm front. Flow aloft looks a bit messier during this time period and suspect we'll see a return of some shra/tstm chances ahead of another front penciled in for Saturday night. 47
AVIATION
(18Z TAF Issuance)
Issued at 1222 PM CDT Sun May 5 2024
Another round of showers and storms is entering the area this afternoon. Expect activity to increase across SE Texas with the potential for strong to severe thunderstorms. These storms may produce gusty erratic winds and large hail. VFR CIGs across the area at present, expect MVFR to mix in there this afternoon as next round of showers moves in. CIGs overnight will drop to MVFR/IFR levels with some MVFR VSBYs closer to sunrise. Expect CIGs to remain at least MVFR through the period with some improvement near the end of the period. Adams
MARINE
Issued at 242 PM CDT Sun May 5 2024
Fetch of moderate onshore winds will maintain somewhat elevated seas for the next several days. Have maintained caution flags for all waters this evening for winds. Will probably need to be extended beyond 20nm overnight with seas still hanging around 6ft.
Mariners should note high flows from area rivers, creeks and streams will lead to above normal water levels and strong currents in the bays and ICWW well into midweek and can make navigation difficult.
Showers and thunderstorms should taper off this evening with only slight chances, if any, expected into midweek. Onshore flow should prevail until the next cold front pushes off the coast Thursday night. 47
HYDROLOGY
Issued at 242 PM CDT Sun May 5 2024
The Flood Watch will expire at 7pm CDT Sunday evening. Today's showers/storms and the overall heavy rain threat will come to an end later this evening. Although some scattered showers are possible on Monday, this is not expected to result in any additional flooding.
Rivers will remain swollen for days (possibly weeks), so please continue to take caution. Do NOT go around barricades and stay out of the floodwaters. Do NOT return to homes until officials deem that it is safe.
Moderate to major river flooding continues for parts of Southeast Texas, particularly along portions of the Trinity, San Jacinto, and Navasota rivers. The following river points are currently at Major flood stage as of Sunday afternoon:
- Trinity River (Riverside): Major Flood Stage - Trinity River (Liberty): Major Flood Stage - Trinity River (Goodrich): Major Flood Stage - Trinity River (Moss Bluff): Major Flood Stage - West Fork San Jacinto (Humble): Major Flood Stage - San Jacinto River (Sheldon): Major Flood Stage - Navasota River (Normangee): Major Flood Stage
Remember to heed any instructions from your local officials and to never travel through flooded areas or roadways. TURN AROUND, DON'T DROWN. Please monitor updated forecasts via the NWS AHPS website and/or the new NWS NWPS webpage (https://water.noaa.gov/) as the river flooding continues.
