000 FXUS64 KHGX 170300 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 900 PM CST Fri Feb 16 2018 .UPDATE... It looks like the front has finally stalled out between IAH and Hobby with a few showers still ongoing along it. Sea fog has already begun to roll into the coastal zones this evening, but the front will limit its inland progression. For areas south of the front, fog will likely settle in tonight and remain in place until late morning or midday Saturday. 11 && .PREV DISCUSSION... /ISSUED 604 PM CST Fri Feb 16 2018/ AVIATION... A cold front evident on TIAH stretches from IAH to just north of SGR this afternoon. Expect this boundary to continue translating south towards HOU over the next 1-2 hours, resulting in a light northerly wind shift. Weak convergence in the vicinity of the front has been enough to produce a few light rain showers across the Houston metro and have inserted a VCSH mention in for HOU and SGR through early evening. Strengthening southwesterly flow 925 MB this evening may result in this frontal boundary stalling near HOU and possibly lifting north towards IAH during the overnight hours. Expect winds in the vicinity of the front to remain light and variable overnight with terminals south of the frontal boundary experiencing LIFR to IFR conditions as low ceilings and fog develop. Webcams show sea fog just beginning to enter the lower Galveston Bay area and have delayed onset of lowered visibilities for GLS as a result. As light southerly winds along the coast back ahead of the front this evening, expect sea fog to overtake the terminal with anywhere from VLIFR to IFR visibilities persisting through midday. Mixing south of the stalled boundary on Saturday should allow for ceilings to lift to MVFR and scatter to VFR by the afternoon. A secondary cold front entering the region on Saturday afternoon will result in the development of isolated SHRA near CLL as it begins to approach the terminals after 21Z. Huffman PREV DISCUSSION... /ISSUED 348 PM CST Fri Feb 16 2018/ DISCUSSION... Weak front is slowly moving through the region. It should gradually be losing support for a continued southward push this evening and guidance continues to show it stalling somewhere between I-10 and the coast overnight. It`ll probably meander between Highway 59 and the beaches through Saturday night. Although there`s not a lot of forcing, think there`s probably enough llvl saturation and isentropic lift to maintain lowish POPs in the fcst. Areas of dense sea fog will persist south of the boundary. As lee side pressures fall, look for the stationary front to head back north on Sunday. The broad upper ridge that has been situated across the Gulf Coast will make its way eastward and off the southeast U.S. coast early next week as the next western trof digs southward. A more pronounced southwest flow aloft will evolve going into midweek as the eastern ridge expands northward and western trof southward. Llvl s/se flow will increase thru the same time period as pressure gradient tightens. The next cold front will approach the area ~Wednesday next week. With very little upper-level support for a continued southward push, the front is likely to become stationary near the coast. This type of pattern (blocking high to the east, trof to the west, sw flow aloft transporting Pacific moisture and upper disturbances, deep Gulf moisture in place, upper diffluence, and a stationary boundary) has been known to be a prolific rain producer across the area. We`re still a long way off--but just something we`ll be keeping an eye on in the coming days. 47/22 MARINE... A Dense Fog Advisory is currently in effect for the nearshore waters this afternoon. Sea fog will likely roll back into the bays late this afternoon into the evening hours, and a Dense Fog Advisory will likely be needed once again for both Galveston and Matagorda Bay. The development for sea fog will continue through the weekend, as warm moist air remains situated over cooler shelf waters. Onshore winds will pick up slightly Saturday morning in the offshore waters, and the lingering frontal boundary will shifts northward through the day Saturday. Surface high pressure will build into the area from the north late Saturday into Sunday and winds will become easterly by Sunday morning. Onshore flow will increase approaching SCEC criteria Monday into Tuesday as a southeasterly fetch sets up across the Gulf of Mexico. This will bring added moisture to the region, through mid-week. Wave heights will also increase to between 3 to 5 feet. The next frontal boundary is forecast to reach SE TX next Wednesday. Latest global guidance is showing the front stalling before reaching the coast, which could hinder the clearing of sea fog from the coastal waters. Hathaway $$ && .PRELIMINARY POINT TEMPS/POPS...
