NWS Austin/San Antonio, TX wrote its last area forecast discussion before the first event at Apr 29, 1:48 AM CST, 1 hour 17 minutes earlier.
Area Forecast Discussion National Weather Service Austin/San Antonio TX 248 AM CDT Wed Apr 29 2020 .SHORT TERM (Today through Thursday)... As we wade through the severe weather event that will consume most of our attention in the pre-dawn hours, the emphasis for the short term will be on the few hours of thunderstorms that might remain east of I-35/I-37 this morning. While large hail and damaging winds will be of a higher emphasis north of HWY 90 through 7 AM, the storm intensities are expected to weaken by 7 AM, with perhaps a marginally severe storm forming mainly south of HWY 90. HREF reflectivity stamp would suggest a timing of the wind threat to subside first with the leading edge of storms and strongest convergence to be south of our counties by around 7 AM, but some stronger echoes trailing behind might still contain enough lift for a continued hail threat up to around 9 AM. By late morning, only some residual showers are expected. Much drier air arrives with gusty N winds of 15 to 25 mph, and there could be still enough wind for an hour or two of elevated fire weather conditions over Val Verde county. Further south, the dry air advection over the Rio Grande Plains looks less dramatic from the NE winds. High temperature trends today look fairly steady over the past few model cycles and the evening should be extra pleasant after the winds die down. Morning lows could fall into the upper 40s in a few low lying pockets in the Hill Country. Light winds, sunny skies, and dry dew points will make for a wide diurnal range for Thursday, and highs should actually rebound to above climate norms for the end of April. && .LONG TERM (Thursday Night through Tuesday)... Summer like weather is expected. Upper level ridging eases into our area late week into the weekend then flattens next week. Southerly lower level flow brings a more humid airmass with elevated heat index values. High temperatures of 100 to 105 are expected across the Rio Grande Plains with mid and upper 90s elsewhere. Heat index values will be about 5 degrees warmer than temperatures. Strong capping from warm mid level temperatures keeps rain chances out of the forecast. The next chance of showers and thunderstorms may be next Tuesday night into Wednesday when a cold front is forecast to move across our area. However, the ECMWF brings the subtropical ridge over us capping the airmass and the GEM keeps the front north to add uncertainty. && .PRELIMINARY POINT TEMPS/POPS...
