Area Forecast Discussion National Weather Service Austin/San Antonio TX 236 PM CDT Fri Apr 28 2023 ...New MESOSCALE UPDATE... .SEVERE THUNDERSTORM WATCH 170 IN EFFECT FOR MOST OF SOUTH-CENTRAL TEXAS UNTIL 9 PM THIS EVENING... A Severe Thunderstorm Watch has been issued for all areas outside of Val Verde and Edwards Counties until 9 PM this evening. Severe thunderstorms have erupted near a dryline/surface low/warm front intersection just to our north, and are expected to continue developing south and west into our Hill Country counties over the next couple of hours. Large (>1"/quarter size) to very large (>2"/lime size) hail will be of high concern as storms first develop, with damaging straight line winds ranging from 60 to 75 MPH becoming the predominant threat as storms begin to swiftly merge into a line. While secondary to the large hail and damaging wind potential, isolated tornadoes can't be ruled out. Activity will likely move over the I-35 Corridor during the evening rush. Those with essential travel plans should be prepared to seek immediate safe shelter if storms begin to approach. Never ride out severe thunderstorms in a vehicle. We are also monitoring deepening cumulus and thundershower activity to the west of the Rio Grande River in Maverick County. Several lightning flashes have been detected by satellite in this activity. Like the storms to our north, large hail and damaging winds will be the primary concerns in these cells. An isolated tornado can't be ruled out. && .SHORT TERM... (Tonight through Saturday night) Issued at 146 PM CDT Fri Apr 28 2023 ...Key Messages... * A line of storms will develop across the Hill Country by around 4PM, move eastward across the I-35 corridor between 6-8PM, and into the Coastal Plains from 8PM-11PM. * There is a level 3 of 5 risk for severe storms along this line. Scattered to numerous instances of damaging straight-line wind gusts and large to very large hail possible. Isolated tornado also possible. * While the speed of the system will prevent a widespread heavy rainfall threat, some isolated pockets of quick flooding are possible near and east of I-35 where more intense rainfall rates could occur. * Remain weather aware this afternoon and evening. Given the potential timing of storms during the late afternoon into the Friday evening commute, those with travel plans should pay close attention to the radar and any potential watches and warnings. The morning low stratus and patchy fog with the ongoing moisture advection has mixed out into the afternoon with mostly sunny skies now across the region. Temperatures have quickly warmed and will continue to do so through the mid-afternoon. This will continue to aid in the atmosphere becoming increasingly unstable ahead of the approach of a strong front and the potent parent upper level low pressure system. This will lead into the risk for severe storms that is highlighted below. Some discrete convection remains on target to develop just to the north of the region starting mid-afternoon, near a triple point and south along a dryline. The CAMs remain in strong agreement that convection will unzip southwest into the Hill Country late afternoon and eventually into an MCS near the I-35 corridor early this evening, where a strong pool of instability resides. With steep elevated lapse rates overspreading the region, MLCAPE values are indicated to be on the order of 3000-3500 J/kg, in a region of 0-6KM bulk shear values of around 50 kt. This supports a severe threat of initially large to very large hail where the storms first unzip late this afternoon, transitioning to a damaging straight-line wind threat into and to the east of the I-35 corridor. SPC highlights the majority of the region in a level 3 of 5 (Enhanced) for severe storms with the potential in some isolated intense storms of hail 2+ inches in diameter and bowing segments of 75+ mph or greater. The low-level shear profiles and hodographs may also be enough to where an isolated tornado threat may be possible as well. While this is a lower confident hazard compared to the large hail and damaging wind threat, it could materialize if the updraft/downdraft convergence zone can remain balanced and any local surges take place orienting more line-normal to the better 0-3KM bulk shear vectors. The storms as they advance into and across the coastal plains could become undercut by the forward propagating front and/or outflow but latest CAM guidance has become less inclined of this happening compared to earlier runs. Due to the speed of the system, widespread heavy rainfall is not expected. Nevertheless, some pockets of more intense rainfall rates could lead to an isolated flash flooding threat near and east of the I-35 corridor. On average, rainfall amounts west of the I-35 corridor counties is expected to remain around or less than 1/4 of an inch. Along and east of I-35 rainfall amounts of 1/2 to 1 1/2 inches are forecast, with a few pockets of 2-3 inches possible east of I-35. Behind the cold front, windy conditions will also be expected to develop from out of the north-northwest with gusts of 35 to 45 mph possible this evening across the Southern Edwards Plateau and western Hill Country this evening. A Wind Advisory will be issued across these areas from 00Z to 06Z. Breezy conditions are expected elsewhere from this evening into tonight before winds start to uptick into/through Saturday morning with daytime heating. Winds could gust again into the 35 to 45 mph range. The need for another wind advisory will be possible across a larger portion of South- Central for that secondary increase in winds. For locations to the west that could miss out on tonight's wetting rains, elevated to near critical fire weather concerns may exist given the breezy northwesterly flow and drier air during Saturday afternoon. Becoming much cooler from tonight into Saturday behind the front, with overnight lows ranging from the upper 40s into the 50s and afternoon highs ranging from the low 70s to the low 80s along the Rio Grande. Another cool night will be in store during Saturday night as the winds slacks off with overnight lows in the mid to upper 40s and low to mid 50s. && .LONG TERM... (Sunday through Friday) Issued at 146 PM CDT Fri Apr 28 2023 Most of the long-term portion of the forecast will be rain free as upper level subsidence then upper level ridging moves into the region. This should lead to drier air at the surface which should lead to high temperatures Sunday through Wednesday in the 80s to 90s with lows in the lower 60s making pretty nice days. Dewpoints will pick back up Wednesday afternoon through the remainder of the forecast period. At the same time, a couple of weak disturbances could translate through the region bringing some low rain chances back into the forecast. The NBM keeps everything at 20 percent or less and see no reason to deviate from that at this point. Otherwise, highs Thursday and Friday will be in the upper 80s to lower 90s with lows in the upper 60s to lower 70s with the higher surface moisture. && .AVIATION... (18Z TAFS) Issued at 1223 PM CDT Fri Apr 28 2023 Low stratus and patchy fog from this morning along the I-35 TAF sites are mixing out with flight conditions now returning to VFR flight conditions. Our attention then turns to the risk for convection from later this afternoon through this evening with threat for severe weather. Storms are expected to initiate along the cold front across Central Texas around 19-21Z and unzipper into/across South Central Texas into a squall line along the southward moving front. Environmental conditions will support scattered to numerous severe storms with the hazard for straight- line wind gusts in excess of 50 kt, large hail, and an isolated tornado. This line of storms are currently expected to move across the I-35 corridor and AUS/SAT around the 23Z-01Z timeframe. Few showers may be possible behind the initial squall line otherwise expect the development of gusty N to NW winds behind the departing line of storms and cold front, with gusts between 20 to 30 kt expected. && .PRELIMINARY POINT TEMPS/POPS...
