Thunderstorms have developed in the warm, moist flow ahead of a
surface boundary. We have a Tornado Watch in effect until 8 PM with
favorable conditions for a few tornadoes, hail up to two inches,
straight line wind gusts up to 70 mph. The surface boundary is
currently stretched from northern Burnet to southern Real and will be

the evening from west to east. The upper pattern will become zonal
Sunday and dry weather will move in. Temperatures will increase will
highs in the 90s across the area and very warm lows Monday morning.

.LONG TERM (Monday through Saturday)...
Monday night and Tuesday another deep upper level trough will move
into West Texas bringing the next chance for convection. The strength
of any storms is uncertain at this time, but it is that time of year.
After this system passes, the upper flow will become southwesterly

will move through the pattern bringing a slight chance for convection
