We now have a severe thunderstorm watch for portions of the hill Country, Central Texas, North Texas, and Northeast Texas. Junction, Kerrville, Austin, Waco, D/FW, Paris, Texarkana, Marshall, Tyler, Palestine, and Bryan/College Station are a few (of many) towns included in this watch. For reference please see the graphic contained within this blog post. The strongest storms over the next several hours will likely be hailers capable of hail near or slightly above the size of golfballs. I can’t rule out a few hail stones larger than that, but I’m not sure we’re going to see that level of updraft organization. Damaging straight-line winds are possible and will become more likely once storms grow upscale into a squall line by early evening.
