NWS Houston/Galveston, TX wrote its last area forecast discussion before the first event at Jul 31, 11:35 AM CST, 4 minutes earlier.
Area Forecast Discussion National Weather Service Houston/Galveston TX 1235 PM CDT Tue Jul 31 2018 .AVIATION... A strong to severe storm is currently progressing through IAH and approaching HOU and SGR. Winds in excess of 50 knots are possible in some areas with torrential rainfall, frequent lightning, and ponding on runways. Visibilities can get as low as 1/4 sm in the heaviest areas. This storm should progress through the southern terminals through 20Z. Outflow behind this storm, combined with other outflow boundaries and the sea breeze, will allow shower and thunderstorm coverage to continue through the early evening with gusty winds and heavy rainfall. We return to VFR late this evening with calmer northerly winds as a cold front passes through Southeast Texas. 22 && PREV DISCUSSION /Issued 406 AM CDT Tue Jul 31 2018/... SHORT TERM [Today through Wednesday Night]... The main cluster of thunderstorms has finally pushed eastward out of the area this morning. The cold front itself remains just to the north of our area, situated between Waco and College Station as of 330 AM. Expect another round of showers and thunderstorms as this front continues to sag southward through the area today. Short term guidance on the whole isn't performing very well, with several of the models struggling to pick up on already ongoing thunderstorms. As convection over our area has died off or moved eastward for now, looks like we'll have a bit of a break this morning followed by another round of thunderstorms firing along the front once we get some daytime heating. As we saw earlier, a few of these storms could be strong to severe and capable of producing gusty winds, small hail, frequent lightning, and locally heavy rainfall. SPC has placed portions of the Piney Woods Region in a Marginal Risk for severe weather to reflect this potential. The cold front should clear the coast sometime this evening, bringing an end to the thunderstorm activity. High temperatures could be tricky today depending on the timing and coverage of the thunderstorms this afternoon. For now, have high temperatures pegged generally in the low 90s, with mid 90s over portions of the Brazos Valley that should be done with most of the convection by peak heating. Unfortunately the cold front itself won't be bringing much relief in the way of lowering temperatures. High temperatures on Wednesday are still forecast in the low to mid 90s, although much drier conditions will at least make it feel a little bit better than it has been. Mostly sunny and dry conditions are expected for Wednesday in the wake of the front. 11 LONG TERM [Thursday through Tuesday Night]... Drier conditions are expected for both Wednesday and Thursday, as we move to the west side of the upper level trough axis and PWs decrease to just over 1". Cooler temperatures are expected as heights fall slightly on Friday. Subsidence should weaken with lower heights, so an isolated shower can't be ruled out for Friday... particularly along the coast. Another round of rain is looking promising for Saturday, as an inverted trough moves into South Texas and we enter an area of weakness between two ridges. Heights appear to build again on Sunday. Moisture returns on Monday, increasing the chance for showers and thunderstorms that will stick around through Wednesday due to a weakening in the ridge and falling heights. Randall MARINE... A weak frontal boundary may push through the area today and tomorrow. Offshore winds should develop tonight into Wednesday but will be short lived. Onshore winds develop again Wednesday night into Thursday. Onshore winds then increase to around 10 to 15 knots over the weekend. Light winds should keep low seas in place through the end of the week. Overpeck && .PRELIMINARY POINT TEMPS/POPS...
