Thunderstorms formed along a slow-moving cold front in Central Texas and moved through South-Central Texas. The slow movement led to high rainfall rates and locally heavy rain which in turn led to flash flooding.

Area Forecast Discussion National Weather Service Austin/San Antonio TX 132 AM CDT Fri May 30 2025 ...New SHORT TERM, LONG TERM... .SHORT TERM... (Today through Saturday) Issued at 131 AM CDT Fri May 30 2025 Key Messages: - A complex of thunderstorms for the overnight into early this morning with potential of isolated to scattered severe storms - Pockets of heavy rainfall could lead to instances of isolated to scattered flash flooding - North-northeasterly flow with slightly cooler, drier air behind the storm complex and frontal boundary from Friday night into Saturday An organized complex of thunderstorms from earlier convection over West and Central Texas is on its final southeastward approach on entering our CWA along a frontal boundary. At the time of this writing, most of the activity has remained below severe limits but continues to produce moderate to heavy rainfall, gusty winds, and small hail. Some short term guidance shows the possibility of some re-intensification of storms overnight across our region, mainly across our western areas, where the local instability is a tad bit higher. Isolated to scattered severe storms remain possible as a result with the threat of damaging winds and large hail. Rainfall rates of 1 to 2 inches per hour in the storms could also result in some instances of flash flooding, especially across any locations that have seen greater rainfall throughout the last few days. The complex should clear the I-35 corridor by the mid-morning before weakening and/or clearing the coastal plains through the early afternoon. North-northeasterly winds arrive in wake of this storm complex and the front. This will funnel in some slightly drier and cooler air across the region. The front is likely to get hung up to the south across portions of Corpus Christi's CWA and to the west along the Mexico higher terrain. This is where the highest PWATs will pool through the remainder of the short term period. Enough moisture is expected to remain with enough diurnal heating for low to medium rain/storm chances across our southern and western most areas from Friday night through Saturday, with the best chances peaking late Friday night into early Saturday across the Rio Grande Plains. Elsewhere, conditions look to stay primarily dry and stable. Behind the complex, expect for high temperatures to only peak into the low to mid 80s across the northern half of the region during this afternoon while southern reaches of the region still could reach up into the 90s. Overnight lows into Saturday morning range from the mid 60s across the Hill Country to the low to mid 70s elsewhere. Saturday is expected to feature afternoon highs mainly in the 80s to near 90 degrees across the region. && .LONG TERM... (Saturday night through Thursday) Issued at 131 AM CDT Fri May 30 2025 Key Message: - Low chances for isolated showers and storms into early next week. The leftover mid-level moisture associated with TS Alvin in the eastern Pacific is forecast to thin out Saturday night, resulting in lessening rain chances moving into Sunday in concert with an approaching upper-level ridge. Southerly return flow is forecast to develop beneath this ridge, so dew points look to trend upwards heading into next week. While the ridge should keep most of our region free of rain Sunday, a late afternoon shortwave diving south along the ridge's eastern periphery over East Texas could spark some isolated shower and storm activity mainly over the eastern half of our CWA Sunday afternoon and evening, with possible contributions to lift from the onshore flow of Gulf air and divergence ahead of the trough. Given the broader ridging, coverage should be low, so for now rain chances of 15 to 20 percent are portrayed mainly for the I- 35 corridor eastward late Sunday. More of the ridge shifts over our area Monday, which should keep most of early part of the day quiet. A trough is forecast to impinge on the ridge's western flanks later in the day, with medium range guidance indicating a corresponding increase of convective activity along the dry line over West Texas and atop high terrain over Mexico. Warm air aloft associated with the ridge will favor more stable conditions over our area, but a few storms could sustain into the southern Edwards Plateau and Rio Grande Plains later in the day into the evening before weakening overnight. With several disturbances embedded within the broader troughing over the Rockies, a similar pattern could play out again Tuesday, perhaps shifted slightly northeast depending on the timing of the individual disturbances. With the shortwaves ejecting out over the Four Corners region into the Central Plains, the focus of lift looks to be mainly north of our area, so rain chances both days currently reach 25 percent at most. Upper-level ridging strengthens midweek, causing the subtropical jet the bow outwards north of our area. This will tend to put storm tracks mainly north of our area, but not much would need to change for rain chances to continue mainly for the northern half of the CWA. Southerly flow under ridging aloft means temperatures will be on the upswing heading into next week. Sunday afternoon marks a return to the 90s for South Central Texas, and continued southerly flow should get most locations into the upper 90s by midweek with low 100s along the Rio Grande. Lows are forecast to be in the 70s throughout next week. && .AVIATION... (06Z TAFS) Issued at 1219 AM CDT Fri May 30 2025 VFR flight conditions begin the period but a storm complex across Central and West Texas will advance southeastward with potential impacts overnight through early morning at the area terminals. This thunderstorm activity could impact the terminals between 09Z and 15Z. Some showers could precede or linger behind the complex for a couple of hours. Gusty winds, frequent lightning, heavy rainfall, and small hail could be associated with activity. Winds turn northerly behind the front and bring MVFR ceilings through mid to late morning at KAUS and KSAT. Ceilings lift into and through the afternoon to VFR levels. Winds decrease in speed and become variable into Friday night. .PRELIMINARY POINT TEMPS/POPS...
