The SPC is forecasting a slight risk of severe thunderstorms for portions of Texas overnight and early Tuesday, ahead of the major winter storm we've been talking about for the past few days.
NWS doppler radar near Abilene currently shows thunderstorms erupting along and immediately West of the cold front across Northwest Texas:
As the evening wears on, increasing upper-level energy will overspread the region from the West, while at the same time the surface cold front will be diving to the Southeast. This will result in increasing thunderstorm activity across the Hill Country and adjacent areas.
When the heart of the upper-level energy nears the frontal boundary and increasing low-level moisture later tonight, some thunderstorms may produce gusty winds and hail to severe limits across portions of central and southcentral Texas during the predawn hours on Tuesday.
