TO LAMPASAS LINE LATE THIS AFTERNOON. THIS FRONT WILL MOVE EAST/SOUTHEAST AROUND 25 MPH AND MAY PROVIDE THE FOCUS FOR THUNDERSTORM FORMATION. A WARM LAYER OF AIR...OR CAP...JUST ABOVE THE SURFACE WILL BE A LIMITING FACTOR TO STORM DEVELOPMENT... HOWEVER...ANY STORMS WHICH DO MANAGE TO BREAK THE CAP HAVE THE POTENTIAL TO QUICKLY BECOME SEVERE IN THE MOIST AND VERY UNSTABLE AIR AHEAD OF THE FRONT. LARGE HAIL AND DAMAGING WINDS WILL BE THE PRIMARY THREAT WITH THESE STORMS. THE VERTICAL WIND PROFILES ARE NOT FAVORABLE FOR PRODUCING STRONG MESOCYCLONES...SO TORNADOES ARE NOT EXPECTED WITH THIS EVENT.
