Key Message:
- Marginal chances of strong to severe storms Edwards Plateau and Rio Grande Plains late afternoon into evening.
The latest GOES-19 Water Vapor imagery shows a mid-level low centered over southern Utah, along with broad southwesterly flow over Texas. Looking at regional DCP Distinction imagery, towering cue and perhaps the beginnings of a couple of stronger storms are noted over northern Mexico early this afternoon. Latest hi-res guidance has shown this convection over northern Mexico developing a bit earlier than previously thought, so coverage may be a bit broader and further east if storms can maintain once they come off the higher terrain. There is just enough mid-level lift to keep storms alive coming off the higher terrain, but that doesn't look to last long. Have opted to increase PoPs further east, but hold up just west of I-35/I-37 Corridor. Any storms that make it should fall apart before midnight tonight, with perhaps a lingering shower making it as far east as western Bexar County.
On Tuesday, warm and muggy conditions continue, with rain free conditions expected for most of the day. Any strong or severe storms are expected to remain over the Edwards Plateau or into the SJT CWA
SPC currently has portions of Val Verde County within a Marginal risk for severe storms, but the threat largely remains west of our region. As warm air advection increases ahead of our first decent rain chance across the whole region Wednesday morning, scattered showers are possible before daybreak.
LONG TERM
(Wednesday through Monday)
Issued at 221 PM CDT Mon Apr 28 2025
Key Messages:
- Springtime weather featuring warm, humid conditions, and daily chances for rain/storms
- Highest rain/storm chances likely to focus on Wednesday, Friday through Saturday, and again early next week
An upper level storm system will move across the Texas panhandle into Oklahoma from Wednesday through Wednesday night. The greatest lift and thus rain/storm chances look to concentrate to our north across the Fort Worth and San Angelo CWAs. However, the activity does look to extend southward, at least across portions of our northeastern/northern most areas. This is where medium (40-60 percent) chances for rain and storms will align. The activity will remain more limited elsewhere with low (10-30 percent) chance of rain and storms. Thursday is likely to fall in-between the main parent upper level storm systems but an embedded shortwave is possible to arrive from the west in the west-southwesterly flow.
This could induce isolated to widely scattered activity from late Thursday through Thursday night, favoring the western and southern half of the region. Rain and storm chances increase again Friday through Saturday as a cold front slides southward and provides additional lift. The front stalls across near our southern border with the Corpus Christi CWA The front could then lift back to the north out of our region by Sunday. While this could allow for the most concentrated lift to move out, the warm and humid southerly flow may be enough to keep at least some low end (20-30 percent)
rain and storm chances. Another upper level storm system then advances into the Four Corners entering early next week and this currently looks to enhance rain/storm chances once more beginning next Monday. The 00Z LREF grand ensemble guidance shows about a 50 to 75 percent chance for 1 inch or more of rain across the region through next Monday and a 20 to 35 percent chance of 2 inches or more. Isolated locally higher amounts occur where storms align.
Environmental parameters with the combination of instability and deep layer shear, may support strong to possibly severe storms at times.
The afternoon highs are to generally run in the 80s to the low to mid 90s through the period. Thursday is expected to be the warmest day while highs trend a little lower Saturday into Sunday in the wake of the front. Overnight lows will run from the 60s to the low 70s in general. However similar to the afternoon highs, lows run slightly lower in wake of the front Friday night into Saturday morning and Saturday night into Sunday morning. Clouds will trend more common than sun this week with the greatest cloud coverage occurring overnight into each morning with the low stratus.
AVIATION
(06Z TAFS)
Issued at 1221 PM CDT Mon Apr 28 2025
Weakening SHRA over the Hill Country to the Rio Grande will dissipate during the next couple of hours with no impacts to the TAF sites.
Some development of SHRA/TSRA is expected on Tuesday late afternoon into evening near the Rio Grande, however PROBs are currently too low to mention at KDRT. MVFR CIGs develop overnight into early morning, lift to VFR around midday, then return Tuesday night. Moderate S to SE winds will prevail. A few gusts up to 30 KTs or so are possible.
