AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1000 AM MDT MON AUG 14 2006

.SYNOPSIS...SOUTHWEST FLOW WILL BRING MOISTURE NORTH ACROSS UTAH
THROUGH WEDNESDAY. A PACIFIC WEATHER SYSTEM WILL MOVE EAST ACROSS
THE AREA ON TUESDAY AND WEDNESDAY.

&&

.DISCUSSION...HIGH PRESSURE RIDGE ALOFT REMAINS CENTERED IN
NORTHWEST NEW MEXICO NEAR THE FOUR CORNERS WITH SOUTHWEST FLOW
ACROSS UTAH TODAY. A WEAK UPPER LEVEL SHORT WAVE TROUGH IS APPARENT
IN WATER VAPOR IMAGERY NEAR LAKE TAHOE. THIS WAVE IS BEGINNING TO
EJECT NORTHEAST FROM THE MAIN WEST COAST TROUGH AND LOOKS AIMED AT
AN ELKO TO IDAHO FALLS TRAJECTORY...JUST GRAZING NORTHWEST UTAH THIS
EVENING AS IT PASSES. OUTSIDE OF THIS FEATURE VERY LITTLE FORCING
FOR ORGANIZED CONVECTION TODAY AND EXPECT THAT NEUTRALLY UNSTABLE
AIRMASS WILL PRODUCE ISOLATED TO WIDELY SCATTERED THUNDERSTORMS
ALONG LOCAL TERRAIN INDUCED CONVERGENCE ZONES. NO UPDATES NEEDED TO
CURRENT FORECAST PRODUCTS. WILL CONTINUE MONITOR THE EVOLUTION AND
TRAJECTORY OF THE EJECTING TROUGH TODAY FOR POSSIBLE INCREASE IN
THUNDERSTORM ACTIVITY THIS EVENING IN THE FAR NORTHWEST CORNER OF
UTAH.

STILL LOOKING FOR AN INCREASE IN THUNDERSTORM ACTIVITY TUESDAY AND
LINGERING INTO WEDNESDAY AS THE NEXT PACIFIC SYSTEM PUSHES INTO THE
AREA.

&&

.FIRE WEATHER...MOISTURE INCREASING FROM THE SOUTH THIS MORNING
ACROSS THE STATE...AND THIS WILL MOVE INTO NORTHERN UTAH BY THE
AFTERNOON. EXPECT WIDELY SCATTERED SHOWERS AND THUNDERSTORMS IN THE
MOUNTAINS AND ISOLATED COVERAGE ELSEWHERE...THOUGH COVERAGE COULD
INCREASE TO WIDELY SCATTERED THIS EVENING AND OVERNIGHT OVER
NORTHWEST UTAH AS AN UPPER LEVEL DISTURBANCE MOVES THROUGH. LOWER
LEVELS REMAIN DRY THERE...SO THE POSSIBILITY OF DRY LIGHTNING
EXISTS. THEREFORE...FIRE WEATHER WATCH IN EFFECT FOR THIS AFTERNOON
AND EVENING FOR ZONE 420 WILL LIKELY BE UPGRADED TO A RED FLAG
WARNING. THUNDERSTORM COVERAGE SHOULD INCREASE TOMORROW AS THE
AIRMASS BECOMES MORE UNSTABLE OVER THE AREA.

&&

.AVIATION...THERE IS A 20 PERCENT CHANCE OF THUNDERSTORMS THIS
AFTERNOON AND EVENING. THESE MAY PRODUCE ERRATIC WIND GUSTS IF THEY
PASS NEARBY. OTHERWISE EXPECT A SLIGHTLY DELAYED LAKE BREEZE TODAY
DUE TO INCREASED SOUTH FLOW ALOFT.
