0806 PM CDT TUE APR 08 2008
AREAS AFFECTED...TX HILL COUNTRY INTO CNTRL TX
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 090106Z - 090300Z
A WW IS NOT CURRENTLY ANTICIPATED...BUT TRENDS WILL CONTINUE TO BE
MONITORED FOR THE POSSIBILITY OF AN INCREASING SEVERE THREAT.
SCATTERED THUNDERSTORMS ARE NOW ONGOING ALONG SLOW MOVING COLD FRONT
SOUTH OF THE DALLAS/FORT WORTH METROPLEX INTO THE TEXAS HILL
COUNTRY. RATHER STRONG MID-LEVEL INHIBITION INITIALLY SLOWED
DEVELOPMENT...BUT FORCING ASSOCIATED WITH FRONT MAY HAVE CONTRIBUTED
TO INITIATION. THE BULK OF ACTIVITY APPEARS SLIGHTLY ELEVATED JUST
TO THE COOL SIDE OF THE FRONT...WHICH LIKELY WILL STALL AS A STRONG
UPSTREAM TROUGH CONTINUES TO DIG INTO THE SOUTHWESTERN STATES.
BENEATH A BUILDING HIGH-LEVEL RIDGE...MID/ UPPER FORCING TO SUSTAIN
CONVECTION DEEP INTO THE NIGHT IS STILL UNCERTAIN. BUT...MODERATE
DEEP LAYER SHEAR...PRIMARILY ASSOCIATED WITH PRONOUNCED VEERING OF
WINDS WITH HEIGHT...MAY HELP MAINTAIN CELLS IN A MODERATELY UNSTABLE
AIR MASS...WITH MOST UNSTABLE CAPE ON THE ORDER OF 1000-2000
J/KG...AT LEAST ANOTHER COUPLE OF HOURS.
ACTIVITY NEAR OR JUST NORTHEAST OF THE HILL COUNTRY...MAY BE THE
SLOWEST TO DIMINISH...AS NOCTURNAL STRENGTHENING OF A SOUTHERLY
LOW-LEVEL JET...UP TO 30 KT...COULD ENHANCE LOW-LEVEL CONVERGENCE
ACROSS THIS REGION.
