80S. THESE AFTERNOON SHOWERS AND THUNDERSTORMS WILL CONTINUE
THROUGH THE EVENING HOURS WITH AMPLE HEATING.

ROUND TWO OF AN MCS LOOKS TO BE ON TAP FOR TONIGHT. THE GFS IN

AND 18Z SUNDAY. FOR THIS REASON...WE HAVE EXTENDED THE FLASH FLOOD
WATCH THROUGH SUNDAY AFTERNOON. RAIN AMOUNTS IN GENERAL SHOULD
RANGE FROM 2 TO 3 INCHES...WITH ISOLATE HIGHER AMOUNTS OF 5
INCHES OR HIGHER.

MODELS ARE IN GOOD AGREEMENT AND SHOW THE UPPER LOW OPENING UP ON

PRESSURE BUILDS INTO THE WESTERN COUNTIES. HIGH TEMPERATURES WILL
REMAIN BELOW NORMAL FOR THE WEEKEND WITH LOTS OF CLOUD COVER AND
RAIN POTENTIAL. ONCE THIS SYSTEM MOVES EAST OF THE AREA ON
