224 PM CDT TUE JUN 25 1996

SIMILAR SITUATION TO THAT OF YESTERDAY WITH THE EXCEPTION THAT THE
ATMOSPHERE IS MORE UNSTABLE WITH INCREASED MOISTURE. DEVELOPMENT OF
CU FIELD IS WELL UNDERWAY WITH DWPT TEMPS ACROSS THE PB REMAINING IN
THE MID 60S. SATELLITE ALSO DEPICTS A WELL DEFINED OUTFLOW BOUNDARY
PUSHING SE ACROSS THE NW AND NRN CWA...WHILE KMAF 88D INDICATES
CONVECTION DEVELOPING IN THE MOUNTAINS AND JUST BEGINNING ACROSS
PARTS OF THE PB. MODELS HAVE UPPED POPS ACROSS THE AREA WITH 30 TO
40% FOR MAF. TEND TO SIDE WITH THE HIGHER NGM POPS FOR THE EARLY
EVENING HOURS AS CAP ACCORDING TO A MODIFIED MAF SOUNDING SHOULD BE
ABOUT NIL AND AS THTE RIDGE STILL IS IN PLACE. WILL MAINTAIN WARM
OVER NIGHT LOWS AS MOISTURE REMAINS IN PLACE. BELIEVE LOCALIZED HEAVY
RAIN IS STILL A THREAT WITH STORM MOTION AGAIN EXPECTED TO BE LESS
THAN 10KTS...STORMS ACROSS SWRN AREAS ARE VERIFYING THIS WITH A SLOW
NWRD MOVEMENT INDICATED ATTM.

7H THTE RIDGE IS EXPECTED TO CONTINUE SHIFTING TO THE W THRU
TMRW AS WINDS BACK IN RESPONSE TO TROF ALONG THE CA COAST. 3H THTE
RIDGE OVER E/SE TX WILL ALSO BE PULLED BACK TO THE W AND NW TMWR.
THEREFORE BELIEVE AT LEAST SCATTERED POPS ARE FOUNDED THRU TMRW.
POPS ALSO SUPPORTED BY SE LOW LEVELS WINDS AND BY COOLING 7H TEMPS.
