AN UPPER-LEVEL LOW WILL MOVE SLOWLY ENEWD ACROSS SRN CA FRIDAY AS A
SFC TROUGH DEVELOPS IN WRN AZ. SFC DEWPOINTS TO THE EAST OF THE
TROUGH ACROSS SRN AZ SHOULD BE IN THE LOWER TO MID 50S F. AS SFC
TEMPS WARM DURING THE DAY ACROSS SRN AZ...WEAK INSTABILITY IS
EXPECTED TO DEVELOP FROM THE VICINITY OF TUSCON AND SWD INTO NWRN
MEXICO. ISOLATED THUNDERSTORM DEVELOPMENT COULD TAKE PLACE ALONG THE
INSTABILITY CORRIDOR DURING THE AFTERNOON AS LARGE-SCALE
ASCENT...ASSOCIATED WITH THE UPPER-LEVEL LOW...OVERSPREADS THE
REGION. THIS POTENTIAL FOR CONVECTION SHOULD CONTINUE THROUGH FRIDAY

INSTABILITY SHOULD KEEP THUNDERSTORMS ACTIVITY BELOW SEVERE LIMITS.
