| Area Forecast Discussion National Weather Service Houston/Galveston TX 1230am CDT Wednesday May 8 2024 Long Term (Thursday through next Monday) Issued at 340pm CDT Tuesday May 7 2024 Thursday will start out with a cold front situated between Dallas and College Station, and a dry line across western portion of the Hill Country. PW's between 1.7-1.9" will be pooling south and east of those features. H85 temps look to be between 20-24C and H7 temps 10-14C. Looking for a surface low to eventually form near the intersection of the front/dryline then trek eastward across or near the area during the afternoon and evening hours. Atmosphere looks conditionally quite unstable with high CAPEs (Convective Available Potential Energy - high values indicate potential for severe weather) and low LI's, but the million dollar question is if significant llevel capping will be able to erode enough, or be overcome, to tap into that instability for shra/tstm development. Some of the global solutions seem to think so...mainly across the northern 1/3-1/2 of the CWA. If it does break, some strong-severe cells are possible during the afternoon and evening hours and agree with SPC's conditional DAY 3 slight risk area. Hail & strong winds would be the primary threats. Hires solutions will be coming into view later tonight & tomorrow which should hopefully aid in forecast confidence one way or the other. Once the surface low passes to the east, high pressure will build southward from the Rockies and Plains and push the front through the area and offshore Thursday night. Drier and cooler airmass will then filter into the region late Thursday night into Saturday. As high pressure slides off to the east Sunday, Gulf moisture will flow back into the region. Mid and upper zonal flow looks somewhat messy Sunday & Monday and most global deterministic solutions depict better precipitation chances than NBM during some parts of this time period. Nudged NBM POPs up just a touch for now, but suspect one of those days will need some continued upward adjustments as time progresses. 47 Marine Issued at 340pm CDT Tuesday May 7 2024 Seas holding tough at 6ft at 42019 so will maintain the caution flags beyond 20nm of shore. Fetch of light to moderate onshore winds will maintain somewhat elevated seas for the next several days. 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 intercoastal water way well into midweek and can make navigation difficult. The next cold front pushes off the coast late Thursday night and early Friday morning with moderate north and northeast winds in its wake. E/SE flow resumes over the weekend. 47 Hydrology Issued at 340pm CDT Monday May 6 2024 There is the chance for periods of showers and thunderstorms on Thursday, but is not expected to result in any additional aerial flooding. Rivers will remain swollen for days (possibly weeks), however. Do NOT go around barricades and stay out of the floodwaters. Do NOT return to homes until officials deem that it is safe. Minor 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 either at or forecast to go into Moderate or Major flood stage as of Tuesday afternoon: - Trinity River (Liberty): Major Flood Stage - Trinity River (Goodrich): Major Flood Stage - Trinity River (Moss Bluff): Major Flood Stage - Trinity River (Crockett): Rising to Moderate tonight - Trinity River (Riverside): Moderate Flood Stage - West Fork San Jacinto (Humble): Moderate Flood Stage - East Fork San Jacinto (New Caney): Moderate Flood Stage - Navasota River (Normangee): Moderate 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 flood threat continues. Also of note is that the downstream runoff from the previous rainfall will cause continued rises along the Brazos River through the end of the week. The Brazos River at Sugar Land, Rosharon, and West Columbia are forecast to rise into minor flood stage at the end of the work week and through the weekend. 24 NOAA Houston/Galveston TX Office: Watches - Warnings - Advisories TX...None. GM...Small Craft Should Exercise Caution until 4am CDT early this morning for GMZ370-375. |
