UTAH AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UTAH
1010 AM MDT FRI SEP 8 2000

SYNOPSIS...A WEATHER SYSTEM WILL MOVE ACROSS SOUTHERN AND CENTRAL
UTAH TODAY THEN EXIT THE STATE BY EARLY SATURDAY.  HIGH PRESSURE
WILL BEGIN TO DOMINATE THE STATE ON SATURDAY.

DISCUSSION...SHORTWAVE MOVING ACROSS SOUTHERN UT TODAY WILL KEEP IT
QUITE ACTIVE AND THIS IS WELL COVERED.  THE BAND OF THUNDERSTORMS
AHEAD OF THE WAVE WILL PROBABLY MOVE EAST OF THE AREA BY EARLY
AFTERNOON SO WE MAY NOT SEE THE STRONGEST ACTIVITY ASSOCIATED WITH
IT. HOWEVER THERE IS GOOD SHEAR IN THE AREA THIS MORNING SO WE WILL
NEED TO KEEP AN EYE ON IT.  THE SECOND CLUSTER OF ACTIVITY JUST
NORTH OF P38 WAS VERY ACTIVYT DURING THE NIGHT BUT HAS WEAKENED A
BIT NOW.   IT WILL PROBABLY FIRE UP NICELY AGAIN THIS AFTERNOON AS
IT MOVES ACROSS THE AREAS THAT ARE GETTING SUNSHINE NOW.  THE NEW
ETA ALSO SHOWS A NICE CONVERGENCE/DIVERGENCE COUPLET BETWEEN ABOUT
ZION AND BRYCE CANYON NATIONAL PARKS AT 21Z.  SHEAR HAS DROPPED OFF
A LITTLE BY THEN BUT IS STILL FAIRLY STRONG.  BIGGER QUESTION IS HOW
FAR NORTH THERE WILL BE ACTIVITY.  NORTHERN UT IS UNDER A
DEFORMATION ZONE AND THERE COULD BE SCATTERED ACTIVITY DEVELOP
THERE.  THIS LOOKS MORE LIKELY FROM ABOUT SLC SOUTHWARD AND WILL DO
A QUICK UPDATE TO LOWER THE CHANCE SLIGHTLY FOR THE NORTHERN WASATCH
AND WILL ALSO BEEF UP THE WINDS SLIGHTLY FOR THIS AFTERNOON IN MOST
OF THE WESTERN VALLEYS.  THE ETA ALSO SUGGESTS RAPID DRYING FROM THE
WEST STARTING BY LATE AFTERNOON AND SUSPECT THAT ANY ACTIVTY IN THE
NORTH WILL BE CONFINED TO THE AFTERNOON SO WILL DROP THE MENTIONS
FOR THIS EVENING IN THE UPDATE. h

SLC 31-  CDC 731  SANDERS

.SLC...NONE.
