000 FXUS64 KHGX 200538 AFDHGX Area Forecast Discussion National Weather Service Houston/Galveston TX 1138 PM CST Fri Jan 19 2018 .AVIATION...[06Z TAF] The majority of TAF sites have dropped to LIFR/IFR conditions with a only a few MVFR. Ceilings have dropped to below 500ft in a lot of areas including Houston metro terminals. Visibility remains in the 1-4 mile range with no dense fog. Still a chance some dense fog will develop but that will hinge on winds which range from near 10 knots for KCLL to 5 knots or less elsewhere. Primarily IFR conditions will continue into the morning and gradually improve to MVFR through the day. Look for IFR ceilings to develop Saturday evening into Sunday morning with visibility slowly lowering as well. Showers will be possible through the TAF period with little chance of thunder. Overpeck && .PREV DISCUSSION... /ISSUED 858 PM CST Fri Jan 19 2018/ UPDATE... Eight o`clock temperature observations are in the middle 50s along the coast and across the northern tier of counties this evening. The Houston metro observations were a touch cooler ranging from 50-52 degrees, as they were seeing the occasional break in cloud cover over the last few hours. Easterly winds will continue to veer overnight, and onshore flow will prevail by sunrise. The warm air advection pattern that is in place will continue to allow both temperatures and dewpoints to rise through the night as the coastal trough currently draped over Matagorda Bay stretching southward into the Gulf of Mexico, shifts eastward. Only minor changes made to the forecast in this update. Increased cloud cover over the region tonight as cloud decks continue to lower in height. Based off current observations and the progression of this coastal trough, also went ahead and increased dewpoints slightly and bumped up low temperatures specifically across our northern tier of counties. Patchy fog becoming areas of fog, is still expected to develop beginning in western counties and fill in eastward through the evening hours. Both the SREF and HRRR short term guidance are indicating potentially dense fog developing in the early morning hours between 06-08Z and continuing through the morning. The threat for sea fog also creeps back into the nearshore waters, Galveston Bay, and Matagorda Bay Saturday as ample moisture return and warm air is advected over these cooler shelf waters. Hathaway PREV DISCUSSION... /ISSUED 535 PM CST Fri Jan 19 2018/ AVIATION...[00Z TAF ISSUANCE] Water vapor satellite imagery shows upper level trough over SE Texas and this feature should be moving east tonight into tomorrow. Warm air advection pattern will continue regardless as a ridge builds over Texas in response to a deepening trough over the Desert SW. This means a rather moist airmass will remain in place supporting low ceilings/visibility. Tonight IFR and even LIFR conditions are expected areawide with passing showers. This continues tomorrow with possibly some improvement in ceilings to MVFR by afternoon. Ceilings drop again Saturday evening back to IFR. Visibility may be restricted to a mile or less in a few areas in the morning. Showers may also cause a brief drop in visibility. These conditions should continue into Sunday and not improve until a front pushes through late Sunday night. Overpeck PREV DISCUSSION... /ISSUED 354 PM CST Fri Jan 19 2018/ DISCUSSION... Warmer conditions with periods of rain and fog are expected through this weekend before a cold front arrives late Sunday. Afternoon surface analysis shows a coastal trough stretching from near Rockport to Victoria and south into the Gulf. East of this feature, scattered to numerous showers aided by lift from an upper low sliding across the region continue to build north and east this afternoon. Expect this activity to translate east through the evening and overnight hours as this upper low lifts towards the lower Mississippi Valley with the coastal trough also lifting inland and losing definition as this happens. Southerly flow will spread across the region tonight in response, allowing low clouds to fill in and patchy sea fog to develop along the coast. Inland fog development will also be possible this evening and tonight, especially as the coastal trough loses definition and weakens the surface pressure gradient/low level winds. High resolution guidance does indicate the potential for dense fog and will have to monitor short term trends for any development overnight. Periods of light showers will continue tonight through Sunday as the region remains under an increasing warm air advection regime. With shelf waters having cooled into the mid 40s to lower 50s, sea fog will also be possible during this time across the marine areas and along the coast as moisture deepens across the region. High temperatures will warm into the lower 70s by Saturday and the mid 70s by Sunday as low level southerly flow strengthens as a lee surface low ejects across the Central Plains. An associated Pacific front or dryline developing across North Central/Central Texas during the day Sunday may serve as a focus for thunderstorm development Sunday afternoon and evening, but increasing southwest flow aloft during this time may result in too much mid-level stability for widespread thunderstorm development. A strong thunderstorm cannot be ruled out along this boundary in the Brazos Valley before a cold front overtakes it Sunday night, but the aforementioned mid-level stability and the left front quadrant of a 120+ knot upper level jet located over North Texas indicate this potential may be farther north of the region. Numerous to widespread showers and a thunderstorm or two will develop along the cold front as it pushes southeast across the region Sunday night, before clearing the coast Monday morning. Surface high pressure and dry conditions build into the region Monday through Wednesday with rain chances returning to the coastal and marine areas by Thursday as deeper moisture pushes back into the region. Huffman MARINE... Coastal troughing moving east and active area of shows and a few thunderstorms will continue this evening as the trough shifts east with the upper level s/w. Winds over the coastal water will increase slightly the remainder of the afternoon with building seas. Will continue the SCA for the 20-60nm waters and SCEC nearshore. Fog threat increasing slightly tonight but better chances looks to be with lighter winds and higher dewpoints over the cold shelf waters Saturday afternoon/night. Persistent southerly flow with a 2-4 ft swell Saturday and Sunday. Cold front sweeps through Sunday night and winds gradually ramp up and will likely need SCA by Sunday midnight onwards through Monday afternoon. Showers and possibly thunderstorms with the FROPA. This should end any lingering fog threat. 45 AVIATION... Band of lower CIGS from near ARM-HOU-EFD IFR/MVFR at 21z and this is likely a good confirmation that ceilings will be dropping quickly this evening as coastal trough slides eastward. Patchy fog confidence is fairly high with lower VISBY probably in the CLL-CXO- UTS region. 45 && .PRELIMINARY POINT TEMPS/POPS...
