Area Forecast Discussion National Weather Service Austin/San Antonio TX 1236 AM CDT Thu Jun 8 2023 ...New UPDATE, AVIATION... .UPDATE... Issued at 1236 AM CDT Thu Jun 8 2023 We have raised PoPs along the Rio Grande to account for the MCS that is about to clip the area. Strong to severe storms are occurring with this MCS, with damaging straight-line winds the primary threat where the MCS is bowing out toward Maverick County. Frequent to continuous cloud to ground lightning is also occurring. && .UPDATE... Issued at 1004 PM CDT Wed Jun 7 2023 Elected to slightly adjust the grids, including PoPs, based on the latest observations and the 00Z HREF hi-res member guidance. This does result in a slight bump up in the PoPs for the Hill Country and the I-35 corridor from late morning through the afternoon as several hi-res guidance members pick up on a convective complex advancing through the Hill Country into the I-35 corridor. && .SHORT TERM... (Tonight through Thursday night) Issued at 213 PM CDT Wed Jun 7 2023 The H5 ridge axis that's been hanging out to our west did shift slightly eastward over the past 12-24 hours and is now stretched across the Big bend and far eastern NM. Thus, weak NW flow aloft continues over a moist boundary layer. Sfc obs show temps already in the 80s w/ dew points in the 60s to lower 70. Areas near Austin and south and west of San Antonio will see highs in the low to mid 90s. A broad cumulus field developed during the day, with isolated convection developing late this morning over the Hill Country. These pulse-type storms have been capable of producing brief 0.5" hail and winds up to 30-40 mph, as well as a quick 0.5-1.5" of rain. Like yesterday, this activity will increase slightly in coverage this afternoon before diminishing quickly in the evening with the loss of daytime heating. However, our attention will then turn to the west for the overnight period. There isn't much more than a diffuse dryline today and and little in the way of direct forcing, but daytime heating and venting in the left exit region of the H3 jet should allow a cluster of storms to develop across the Trans-Pecos and Big Bend under the weak H5 ridge. Most guidance indicates a decent chance for this activity to grow upscale before moving into our far western areas. There is a low end risk for some large hail and damaging winds in Val Verde County mainly after 8pm, with storms weakening as they move ESE through the night. An isolated 2"/hr rain total is possible, with very minor flash flooding impacts should that occur, but chances are relatively low that we'll see too many issues. Storms are likely to end before reaching the US-281 corridor late tonight. These storms will help to flatten the ridge axis temporarily overnight, but it will amplify again on Thursday over approximately the same location before shifting slightly east late. Even warmer temperatures are likely to reach the 90s in most locations, approaching 100 near FTN. CAMs keep us in a similar pattern as the past few days, but with the upper jet translating slightly further east we may have some additional upper divergence to assist storm development on Thursday as remnant outflow boundaries and perhaps an MCV from convection in the panhandle tonight drift southeastward into the region. Deep layer shear is marginal but should increase to near 30 knots in the afternoon, and there is likely to be a solid 2- 3kJ/kg CAPE to work with, except on the off chance tonight's storms linger late and make it further east than anticipated. Thus, another Marginal Risk for severe weather is outlooked for most areas except along the Rio Grande closer to the ridge axis. The best chances for any isolated large hail or damaging winds will be from noon to 7pm along and east of US-281. Again, a quick 1-2" of rain is possible in some areas, though others will see nothing at all. Look for storm coverage to again diminish through the evening hours, with overnight lows in the upper 60s and lower 70s. && .LONG TERM... (Friday through Wednesday) Issued at 213 PM CDT Wed Jun 7 2023 Synopsis: Ridging will continue to remain prominent over central portions of the continent through the long term period. This will translate to steadily warming surface temperatures, and overall low chances for appreciable precipitation. Isolated storms can't be entirely ruled out on Friday and Saturday evenings over the far north as shortwave energy ejects into north-central Texas from New Mexico. Widespread precipitation is not expected. Subtropical high pressure is forecast to develop over northern Mexico early next week. With the northern periphery of the feature extending into the Southern Plains, high temperatures will soar to their warmest readings of the year thus far. Friday & Saturday: While mentionable PoPs are present across northwestern Val Verde County only in this update, the potential for isolated to scattered showers and thunderstorms will exist regionally as a broad area of height falls pivots east out of New Mexico. Most guidance shows scattered convective development across the Lower Trans Pecos and Edwards Plateau on Friday evening, with some activity potentially sneaking into portions of Val Verde County before it pushes northeast and away from our CWA. Most progs keep a more organized convective complex to our northeast on Saturday, although multiple consecutive runs of the deterministic GFS suggest the potential for isolated thunderstorm development along the Serranias del Burro Mountains during the late afternoon and early evening hours. Am inclined to treat this solution as an outlier for the time being, though 10% PoPs with no weather mentions have been inserted along the Rio Grande to account for this low-end potential. Will continue to monitor convective trends during this portion of the period accordingly, as an isolated strong storm could be possible in any activity that manages to develop given the combination of ample instability and modest shear that will be in place. Remainder Of The Period: Temperatures will climb to their highest readings of the year so far as a closed area of subtropical high pressure forms over Mexico and nudges north toward the Southern Plains. Ensemble situational awareness tables from the NAEFS show 95th+ percentile 850 mb temperatures becoming established by the Monday-Tuesday timeframe and persisting through the end of the long term. Preliminary PM forecast soundings depict deep, nearly dry- adiabatic boundary layers extending up and through 850 mb across the majority of the region, implying that said warmth should have no issues mixing down to the surface during each afternoon period Monday through Wednesday. Expect that many locations outside of Hill Country will see their first 100 degree highs of the year, if they haven't already. While still several days away, now is the time to begin preparing for potentially very hot conditions next week. Be sure to drink plenty of water, in addition to wearing light-colored and loose-fitting clothing if you plan to be outdoors for prolonged periods of time during this portion of the long term period. && .AVIATION... (06Z TAFS) Issued at 1236 AM CDT Thu Jun 8 2023 A complex of strong to severe TSRA will impact areas near and west of a DRT-CZT line over the next few hours. Gusty winds, hail, and frequent lightning are occurring. In addition, isolated SHRA/TSRA may clip areas near AQA and BMQ overnight. 00Z models have trended higher with coverage of SHRA/TSRA during the day on Thursday. Activity is forecast to develop 15Z-18Z through portions of the Hill Country and move southeast through the I-35 corridor and into the Coastal Plains during the afternoon and early evening hours. Some strong to severe storms are possible, with large hail and wind gusts in excess of 50KT. Away from any SHRA/TSRA activity, VFR conditions are forecast during the TAF period. && .PRELIMINARY POINT TEMPS/POPS...
