Above is a radar image (reflectivity mode which shows precipitation echoes) from the New Braunfels radar (KEWX) taken shortly after 9:30 pm this evening.
The thunderstorm complex that originated west of the Hill Country earlier this afternoon has since rolled through the I-35 corridor and is now advancing Southeast at 40 mph toward the coast. It will soon merge with another thunderstorm cluster moving East from Mexico (currently across McMullen and Duval counties). Gusty winds of 40-50 mph have continued out ahead of the leading edge of the main complex, and an occasional small hail report has also been received over the past hour. The main "show" with this complex is currently heavy rain, gusty winds and frequent lightning.
The lightning show here where I live (near Kyle, TX) has been spectacular ever since storms first started approaching shortly after 7pm this evening. We also recorded wind gusts of 46 knots (53 mph) when the gust front moved through around 7:30 pm. So far, about 1.4 inches of much needed rain has fallen.
Thunderstorm complexes such as the one that formed this evening are really the only source of widespread rainfall for much of central and east Texas during the summer months (other than the much less frequent landfalling hurricane or other tropical system).
