UTAH AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
320 PM MDT THU JUL 5 2001

SYNOPSIS...THE AIR MASS OVER UTAH WILL BECOME QUITE MOIST AND
UNSTABLE TONIGHT AND FRIDAY...AND WILL CONTINUE THAT WAY THROUGH
SATURDAY. THIS WILL ALSO BRING AN END TO THE HEAT WAVE.

DISCUSSION...SCATTERED TO NUMEROUS TERRAIN INDUCED CELLS HAVE
DEVELOPED THIS AFTERNOON IN SPITE OF MID LEVEL CAP, SO IT WAS
PROBABLY NOT ALL THAT STRONG ANYWAY. THIS ACTIVITY SHOULD SPREAD INTO
THE VALLEYS BY THIS EVENING AND PERSIST WELL INTO THE NIGHT...WITH
THE POSSIBLE EXCEPTION OF THE EAST CENTRAL VALLEYS. MOISTURE IS
FORECAST TO INCREASE ON FRI AND CAP GOES AWAY SO ACTIVITY SHOULD BE
EARLY AND WIDESPREAD...WITH SOME AREAS EXPERIENCING LOCALLY HEAVY
RAINS...MAINLY SOUTHWEST. LITTLE CHANGE IS EXPECTED FOR SAT, ALTHO
THE REMAINS OF AN OLD EASTERLY WAVE NOW OVER BAJA WILL ALSO BE MOVING
UP IN CONCERT WITH THE DEEPEST MOISTURE. SO THREAT OF HEAVY RAINS
EXPANDS TO COVER ENTIRE AREA.

THIS WAVE PASSES ON SUN AND THERE MAY BE SOME DECREASE IN ACTIVITY,
ALTHO LITTLE DRYING SO I WOULD STILL EXPECT AT LEAST SCATTERED
AFTERNOON DEVELOPMENT. THEN A MOIST SOUTHERLY FLOW PERSISTS THROUGH
MIDWEEK SO NEED AT LEAST A CHANCE MENTION FOR EACH DAY OF THE
EXTENDED.

THE INCREASE IN CLOUD COVER AND LOW LEVEL MOISTURE TODAY HAS BROKEN
THE HEAT WAVE SOMEWHAT WITH TEMPS RUNNING ABOUT 5-10 DEGREES
BEHIND YESTERDAY'S IN MOST AREAS. SOME ADDITIONAL COOLING IS LIKELY
NEXT TWO DAYS AS CLOUDS AND MOISTURE INCREASE...SO WE WILL HAVE
SOME WELCOME RELIEF FROM THE OPPRESSIVE HEAT.
