CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 260457Z - 260630Z

MARGINAL SEVERE HAIL POTENTIAL MAY BE INCREASING ACROSS PORTIONS OF
SERN/SCNTRL TX EARLY TODAY.

PERSISTENT ISENTROPIC LIFT ATOP LOW LEVEL FRONTAL INVERSION IS
APPARENTLY ADEQUATE FOR PARCELS TO AGAIN REACH AN LFC ABOVE 850MB
ACROSS SERN/SCNTRL TX LATE TONIGHT. BAND OF ELEVATED STORMS WAS NOW
INCREASING ALONG THE ELEVATED FRONTAL SURFACE...GENERALLY ALONG A
LINE FROM HDO TO AUS TO CLL. LATEST RUC SOUNDINGS FROM THE REGION
INDICATED MUCAPE OF AROUND 1000 J/KG AVAILABLE TO THIS NEW ROUND OF
STORMS. STRONG CLOUD BEARING SHEAR OF 40-60KT FURTHER SUPPORTS
UPDRAFT INTENSIFICATION AND PERSISTENCE. UNCERTAINTY EXISTS
REGARDING LARGE SCALE SUPPORT FOR STRONGER UPWARD MOTION ACROSS THE
REGION...AND EXTENT OF SEVERE STORM COVERAGE. ADDITIONALLY...WITH
SEVERE THREAT LIKELY CONFINED TO MARGINALLY SEVERE HAIL OF ABOUT AN
INCH OR SO...CONVECTIVE TRENDS WILL CONTINUE TO BE MONITORED.
