Key Message:
- There is a Level 1 out of 5 risk for severe thunderstorms during the afternoon and evening hours both today and Thursday across portions of the southern Edwards Plateau.
The atmosphere from the early morning rains has been worked over/stabilized due to cloud cover and rain cooled air. However, earlier breaks in the clouds have allowed daytime heating to help generate some convection across portions of the coastal plains into the nearby Rio Grande plains early this afternoon. With continued heating, we should see enough instability develop this afternoon to keep some 20-30% rain chances in the forecast across most of the region. While a strong storm remains possible, it looks like the better setup for severe storms will remain across the the lower Trans Pecos southward into northern Mexico with steeper mid-level lapse rates and sufficient bulk shear (~40kt). Some of this activity could eventually move eastward toward Del Rio during the evening hours, so the chance for strong to severe storms remains in the forecast this evening across the southern Edwards Plateau, including Val Verde county. Should any storms manage to move into the mentioned area, large hail and damaging winds will be the main severe weather concerns. Once daytime heating shuts down, a decrease in convection is anticipated across the region through tonight.
For Thursday, southwest flow aloft looks to remain active and with the onset of afternoon heating, we should see isolated to scattered convection develop, with models hinting at slightly better rain chances across the Hill Country and nearby I-35 corridor. Similar to today, we could see a strong to severe storm across Val Verde county where the Storm Prediction Center maintains a Level 1 of 5 risk for severe storms in the latest Day2 outlook. Hail and high winds will be the main severe weather concerns.
LONG TERM

Warm and humid conditions continue through the forecast period.
Isolated streamer showers beneath a weak cap are forecast through the morning hours on Friday along the I-35 corridor and east. By late Friday afternoon and into the evening destabilization should allow for isolated deeper convection along the I-35 corridor and into the Hill Country, where a 20% chance for isolated showers and thunderstorms are forecast. There is also a very low chance (10-20%)
for isolated thunderstorms in the higher terrain of Mexico and in the Trans Pecos to make it eastward into Val Verde County Friday evening before weakening. The upper level ridge to the south is forecast to amplify slightly into the area over the weekend. A weakness in the flow around the northwest periphery of the ridge could continue low chances (20-30%) for showers and thunderstorms Saturday afternoon and evening across the southern Edwards Plateau and northern Hill Country, with most other areas remaining dry. Dry and warm conditions are forecast for areawide Sunday.
The upper level ridge is forecast gradually slide east of the region Monday into Tuesday. This will allow for an opportunity for upstream convection along the dryline and higher terrain of Mexico to be make it into the Rio Grande Plains, southern Edwards Plateau, and western Hill Country Monday evening, where a low chance (20-30%) for upstream showers and storms is forecast.
The forecast becomes more interesting Tuesday into Wednesday as the next upper level trough to the west moves east. Understandably this far out, there is a large spread in the ensemble guidance on how far south the upper level trough digs and timing across Texas. 20-50% chances for showers and thunderstorms are forecast Tuesday afternoon through Wednesday. These chances could trend highs as we get closer and refined temporally.

Looks like the I-35 terminals will have MVFR cigs through late this evening before MVFR low clouds arrive around midnight. The overnight hours into Thursday morning period likely have a mix of MVFR and IFR cigs. Southerly winds are forecast to dominate this evening through Thursday afternoon and evening. There are slight to low end chances for showers and isolated thunderstorms across the I-35 sites during the afternoon period. For KDRT, a cluster of showers with isolated thunderstorms could affect the site around 02z to 04z based on hires model guidance, Therefore, added a PROB30 group for that time frame.
Other than that, MVFR and IFR are expected overnight through early Thursday afternoon. An east to east-southeast flow at 10 knots or less is forecast to prevail through the forecast period.
