Area forecast discussion, May 6, 6:30 PM CDT, 1 hour 31 minutes before
Area Forecast Discussion National Weather Service San Angelo TX 630 PM CDT Sat May 6 2023 ...New AVIATION... .SHORT TERM... (This evening through Sunday) Issued at 211 PM CDT Sat May 6 2023 ...Scattered strong to severe thunderstorms expected to develop across northern and eastern portions of West Central Texas this afternoon into this evening... Satellite and radar images indicate some convection...mostly elevated...developing across extreme southeast portions of the CWA this afternoon. The latest HRRR progs convective initiation across the northern and western counties between now and this evening...mainly along the surface dryline. The dryline will be a focus for showers and thunderstorms to develop this afternoon into this evening and it appears the strongest convection will be across the Big Country region this evening. SPC continues to advertise a slight to enhanced risk of severe weather across the northern and eastern portions of the CWA for this afternoon and evening. The main hazards are very large hail (up to baseball size possible) and damaging winds (60 to 80 mph) but an isolated tornado cannot be ruled out. Southwest flow aloft will continue to bring weak upper level impulses across portions of northwest Texas tonight into tomorrow. The dryline will continue to provide a focus for showers and thunderstorms to develop across portions of west central Texas Sunday afternoon. SPC has a marginal to slight risk of severe weather across northern and eastern portions of the CWA tomorrow. Large hail and damaging winds will be the main weather hazards for && .LONG TERM... (Sunday night through next Friday) Issued at 211 PM CDT Sat May 6 2023 ...Hot and unsettled pattern to continue for the foreseeable future... Not a whole lot of change from the previous long-term forecast. The mid level ridge that has been the key player in our storm chances the past few days will continue to drift off to the east. By Monday the area will be in generally quasi-zonal flow with a broad, mid- level trough beginning to take shape off of the west coast. This will allow flow over our area to transition back into weak southwest flow. This overall setup will help to continue the hot and unsettled pattern we've been seeing over the past few days. Surface winds out of the south will help to keep a moist boundary layer in place. This, in turn, will allow the dryline to continue to take shape and mix east during the day. Monday and Tuesday will see this dryline activity allowing for chances of strong to severe storms with large to very large hail being the main hazard along with damaging winds. With continued moisture and afternoon highs expected to be in the 90s, SBCAPE values will be in the 2000-3000 J/kg range each afternoon with steep low level lapse rates. As these storms are generally expected to be high based, the tornado threat will remain limited with a greater straight line wind threat from potential downbursts. Activity these days currently looks to be more isolated/scattered in nature and will greatly depend on both the shortwave disturbances that move overhead as well as how far east the dryline can mix through the day. The aforementioned mid-level trough will begin to move east into the Western CONUS late Monday before pushing north and east into the Central Rockies by late Tuesday into Wednesday. The trough is expected to deepen into a low and stall out over the north central Rockies. This will put our area in weak south to southwest flow for the end of the week and into the weekend. This will also usher in some mid-level height falls, allowing temperatures a cool a few degrees back into the 80s and lower 90s, starting on Wednesday. Global models have backed off on precipitation chances for the end of the work week, especially on Friday, so we have followed suite with the forecast. That being said, both show very wet weekends with highly saturated atmospheric profiles and widespread showers and storms. With very little synoptic convergence expected, the current thought is that showers will be influenced by perturbations in the flow aloft. We are optimistic that this will hold true as much of the area is still in desperate need for rain but it's certainly not a guarantee. We will keep a close eye on the end of the week but overall the warm and unsettled pattern that is typical for spring down here will continue for the foreseeable future. && .AVIATION... (00Z TAFS) Issued at 619 PM CDT Sat May 6 2023 Thunderstorms developing over KABI at 2330Z will move northeast, with strong gusty winds up to 40 KTS and IFR visibilities in heavy rain. Storm should be east by 2Z. MVFR visibilities otherwise return after midnight and continue through midmorning. && .PRELIMINARY POINT TEMPS/POPS...
