Area Forecast Discussion...UPDATED National Weather Service Austin/San Antonio TX 1049 PM CST Wed Jan 31 2018 .AVIATION.../06Z TAF CYCLE/ Main change from this TAF cycle vs. previous was to increase forecast visibilities as latest model guidance and current observations suggest greater surface winds to occur overnight. The greater mixing should result in visibilities remaining higher then previous forecast and possibly only dropping into the 2-4SM range. If winds weaken for a short duration however, patchy lower visibilities below 1 SM will quickly develop. The most likely sites impacted by the lower visibilities would be KSAT/KSSF. Regardless, ceilings are still expected to fall to at least IFR in most locations with patchy LIFR and even pockets of VLIFR from 10-15Z. VFR should return by mid to late Thursday morning (after 16Z). KDRT is expected to remain VFR to briefly be MVFR as some light ground fog (5SM) could occur 13-15Z. Surface winds will be out of the south at 5 to 10 knots overnight and then shift to the west 18-20Z and then north after 21Z as a weak cold front shifts through the region. Winds will increase into the early evening thursday near 15 knots with gusts to 20 knots as the pressure gradient tightens. MVFR ceilings will once again be possible 10-12Z Friday morning as north winds continue. && .PREV DISCUSSION... /ISSUED 931 PM CST Wed Jan 31 2018/ UPDATE... New model guidance is showing fog developing across the lower elevation western areas overnight. We have added patchy fog for these areas until mid-morning Thursday. Otherwise, the forecast looks to be in good shape and only needed an adjustment to the hourly grids to account for observational trends. PREV DISCUSSION... /ISSUED 559 PM CST Wed Jan 31 2018/ AVIATION.../00Z TAF CYCLE/ VFR conditions prevail across the region with FL250 cirrus clouds. However, lower ceilings of IFR to LIFR and even VLIFR are expected to develop overnight and into the dawn hours by 09-12Z and linger through 15-16Z. In addition, low surface dewpoint depressions should support development of fog, especially for KAUS, KSAT, KSSF from 10-15Z. Visibilities could fall to 1/2 mile or less at times. Some patchy ground fog will also be possible (4SM) at KDRT from 13-15Z. Conditions will slowly improve through the mid-morning hours back to MVFR and then to VFR by late morning Thursday. Surface winds will continue to be south at 5 to 10 knots overnight but then switch to the west and then north Thursday afternoon as a weak cold front moves through. No precipitation is expected with the front but at least FL100 and above clouds are expected to remain as weak over-running occurs. PREV DISCUSSION... /ISSUED 205 PM CST Wed Jan 31 2018/ SHORT TERM (Tonight through Thursday Night)... Clouds will return this evening into the overnight hours as increased moisture arrives from the gulf of Mexico. Expect patchy to areas of fog to develop along and east of Interstate 35 after midnight tonight into Thursday morning. A cold front will be pushing across central Texas overnight and expected to move across south central Texas midday on Thursday. This is a dry front and precipitation is not anticipated. With south to southwest winds at the surface, expect temperatures to climb into the upper 70s and even lower 80s across the southern part of the Rio Grande. A cool airmass will push across the area Thursday night into Friday in the wake of the cold front with lows in the upper 30s across the Hill Country and upper 40s to lower 50s elsewhere. LONG TERM (Friday through Wednesday)... As the cool airmass remains in place, Friday's high temperatures are forecast to only reach the upper 50s to lower 60s. A surface high pressure system over the Southern Plains is forecast to push to the east and into the Mississippi Valley on Friday afternoon and evening, allowing a southerly flow and moisture to return to south central Texas on Friday evening into Saturday. Chances for rain increase on Saturday as isentropic lift dominates the region and another cold front moves across the area Saturday night into Sunday morning. Once the cold front clears the area on Sunday, expect dry and warm days through Tuesday morning. Another cold front is forecast to move across the area on Tuesday, bringing chances for rain for areas along and east of Interstate 35. Wednesday should be dry with temperatures in the mid to upper 60s. && .PRELIMINARY POINT TEMPS/POPS...
