A concentrated region of scattered convection developed east of the I-35 corridor into this afternoon. Farther west, activity has been more spotty in coverage. The rain will be locally heavy at times.
Additionally, there could be isolated minor flooding where storms remain slower moving and/or train across the same locations, especially with the activity to the east of the I-35 corridor.
Activity likely wanes this evening with loss of daytime heating outside from any lingering stray showers holding across the coastal plains. A similar forecast will be expected to play out for the region on Saturday as coastal surface troughing remains while the mid-level shear axis remains aloft across the area despite the main upper level disturbance starts to shift northward away from the state. PWATs remain elevated as well and nearly identical in comparison to this afternoon. Activity again will likely focus the best east of the I-35 corridor while activity becomes more isolated to widely scattered farther west. Like today, we'll also need to monitor for pockets of heavy rain and perhaps some instances of isolated minor flooding. Activity should decrease entering Saturday night with loss of daytime heating, however, this could then change later overnight into Sunday morning. A deeper southerly flow should then establish and this helps to advect higher PWAT values farther inland as we enter the day on Sunday. This looks to potentially favor an earlier round of activity advecting into the region from out of the south.
Temperatures generally stay below average with daytime highs both this afternoon and again for Saturday afternoon topping out in the mid to upper 80s across majority of the region while areas nearer the Rio Grande reach the low to mid 90s. The overnight lows are generally to range from the upper 60s for portions of the Hill Country to the low to mid 70s elsewhere. Winds will remain light outside from convective influences while cloud cover will vary with greatest coverage across the eastern half of the region.
LONG TERM
(Sunday through Friday)

The recent pattern resulting in below normal temperatures and isolated to scattered showers and thunderstorms will continue as we begin next week. A weak upper trough axis combined with well above normal moisture and daytime heating will keep rain chances fairly high for most areas on Sunday. Models suggest afternoon precipitable water values increase to at or above 2" for most locations along and east of I-35 as well as portions of the Rio Grande plains mainly south of Del Rio. With ingredients for convection aligned favorably, rain chances will be higher for these areas. Moisture levels also remain high farther west into the Hill Country and southern Edwards Plateau and we will keep low end chance Pops in the forecast for these locations on Sunday. Some convection may linger into the evening hours, but the loss of daytime heating will result in a decrease in coverage of showers and storms.
The remnants of the upper trough axis begin to lift northward of the region on Monday. For now, we will keep the forecast dry but may need to monitor the southern Edwards Plateau for a the possibility of some isolated convection. Mid and upper level ridging begins to build over the region Tuesday and remains intact through Friday. This will result in a warming trend for all areas as temperatures return to climatological averages for late July for Tuesday through Friday. We could see a low-end chance for isolated showers and storms near the coastal plains, but coverage will definitely remain low.

Majority of the scattered convection entering this afternoon sits across the coastal plains of Texas. This is where activity will be most favored through early this evening. However, spotty isolated to widely scattered showers and perhaps a thunderstorm or two is possible farther west into portions of the I-35 corridor and Hill Country. Kept VCSH at the I-35 terminals (KAUS, KSAT, and KSSF)
through this afternoon as confidence is low on a thunderstorm directly impacting the sites. Activity decreases into and during this evening with loss of daytime heating. VFR conditions are expected to prevail at the TAF sites into tonight but MVFR to IFR ceilings are expected to develop at KAUS, KSAT, and KSSF early Saturday morning with increasing low clouds. KDRT is expected to remain VFR through the period. At the 30 hr TAF sites (KAUS and KSAT) went ahead and have inserted a PROB30 group with -TSRA into the TAF with scattered convection again becoming possible and perhaps a little farther inland in comparison to today. Outside from local influences from convective activity and outflow, winds should stay below 10 knots through the forecast period.
