Damaging Wind in Utah, August 10, 2004

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1030 AM MDT TUE AUG 10 2004

.SYNOPSIS...HIGH PRESSURE AND DRY CONDITIONS WILL REMAIN OVER THE
GREAT BASIN THROUGH MUCH OF THE WEEK.  MOISTURE IS EXPECTED TO
INCREASE FROM THE SOUTHWEST ON FRIDAY AND LAST THROUGH THE WEEKEND.

&&

.DISCUSSION...WEAK INSTABILITY OVER CENTRAL AND EASTERN UTAH WAS
ENOUGH TO PRODUCE A BAND OF CLOUDS OVER CENTRAL UTAH AND POP A
LIGHTNING STRIKE NEAR DELTA LATE THIS MORNING. THIS BAND WILL SLOWLY
MOVE EASTWARD...BUT A WEAK SHORTWAVE TROUGH OVER CENTRAL NV THIS
MORNING WILL THEN PUSH INTO THE AREA THIS AFTERNOON. WOULD EXPECT
THAT THERE WILL BE ENOUGH INSTABILITY ASSOCIATED WITH THESE TWO
SYSTEMS TO CONTINUE TO PRODUCE ISOLATED THUNDERSTORMS THROUGH THE
AFTERNOON AND EVENING...ESPECIALLY CONSIDERING THERE ARE PATCHES OF
TWO-THIRDS TO THREE-QUARTER INCH PW OVER THE AREA. SINCE THIS IS NOT
A WHOLE LOT OF MOISTURE TO WORK WITH...THE MAJORITY OF THUNDERSTORMS
ARE EXPECTED TO ONLY PRODUCE A FEW SPRINKLES AT MOST...BUT THERE
WILL BE GUSTY WINDS. MOST OF THE CONVECTIVE ACTIVITY WILL BE
CONFINED TO THE CENTRAL AND THE SOUTHEASTERN PART OF THE CWA. THE
AIRMASS SHOULD STABILIZE THIS EVENING AND CONVECTION SHOULD TAPER
OFF FROM THE WEST. HAVE UPDATED FORECASTS TO INCLUDE THE CHANCE OF
THUNDERSTORMS FOR TODAY AND TONIGHT.

STILL LOOKING AT A MAINLY DRY AND STABLE AIRMASS NEXT FEW DAYS AS
RIDGE AXIS REMAINS TO THE WEST AND NORTHWEST FLOW PREVAILS OVER THE
AREA. MOISTURE STARTS CREEPING BACK INTO THE AREA FROM THE SOUTHWEST
ON THURSDAY AS THE RIDGE MIGRATES EASTWARD A BIT AND THE FLOW STARTS
BACKING...AIDED BY A SHORTWAVE TROUGH MOVING ONTO THE WEST COAST.
THE GFS IS CURRENTLY GOING FOR A FAIRLY ACTIVE DAY ON SATURDAY WITH
THE INCREASED MOISTURE AND A SHORTWAVE TROUGH IMPACTING THE AREA.
