AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1002 PM MDT SAT SEP 15 2007

.SYNOPSIS...AN UPPER LEVEL TROUGH ALONG THE NORTHERN CALIFORNIA
COAST WILL MOVE INTO NEVADA SUNDAY AND ACROSS THE REGION SUNDAY
NIGHT WITH A SECONDARY TROUGH TO MOVE THROUGH MONDAY NIGHT. A RIDGE
WILL MOVE BACK IN OVER THE AREA FOR THE END OF THE WORK WEEK.

&&

.DISCUSSION...STRONG SOUTHWEST WINDS DEVELOPED OVER THE AREA AGAIN
THIS AFTERNOON AHEAD OF A CLOSED LOW OFF THE NORTHERN CALIFORNIA
COAST. WINDS SHOULD DECREASE FOR THE OVERNIGHT HOURS...ALTHOUGH
OCCASIONAL GUSTY WINDS CAN STILL BE EXPECTED...MAINLY AT THE HIGHER
ELEVATIONS. A FEW THUNDERSTORMS DEVELOPED OVER EASTERN UTAH WHERE
PRECIPITABLE WATER VALUES OF AROUND THREE-QUARTERS OF AN INCH ARE
PRESENT...BUT MOST OF THESE STORMS HAVE MOVED EAST OF THE CWA THIS
EVENING. A STRONG MOISTURE GRADIENT IS PRESENT ACROSS WEST CENTRAL
TO NORTHEAST UTAH...WITH PRECIPITABLE WATER VALUES OVER NORTHWEST
UTAH AT LESS THAN A QUARTER OF AN INCH THIS AFTERNOON AND DEWPOINTS
DROPPING TO WELL BELOW 0F AT SEVERAL SITES ACROSS WEST CENTRAL AND
NORTHWEST UTAH.

A SHORTWAVE TROUGH EJECTS OUT OF THE CLOSED LOW TOMORROW AND PUSHES
INTO THE GREAT BASIN. MOISTURE WILL SPREAD NORTH INTO UTAH FROM
ARIZONA. HOWEVER...WITH THE FLOW BEING SOUTHWESTERLY...EXPECT
MOISTURE TO SPREAD MAINLY INTO SOUTH CENTRAL AND EASTERN UTAH...WITH
NORTHWEST UTAH REMAINING RATHER DRY. DEEP MOISTURE AND LARGE SCALE
LIFT AHEAD OF THE APPROACHING TROUGH COULD RESULT IN LOCALLY HEAVY
RAINFALL TOMORROW AFTERNOON. IN ADDITION...A STRONG JET SLIDES
ACROSS THE AREA TOMORROW. WITH GOOD SHEAR NEAR THE JET AXIS...EXPECT
SOME ORGANIZED CONVECTION TO DEVELOP TOMORROW. THE ONLY PROBLEM IS
THAT THE JET WILL BE MOSTLY OVER MOISTURE-DEFICIENT NORTHWEST AND
WEST-CENTRAL UTAH. STILL...THERE SHOULD BE SOME STRONG CELLS ALONG
THE FRINGES OF THE MOISTURE SURGE NEAR THE JET TOMORROW.

THE TROUGH SLIDES ACROSS THE AREA SUNDAY NIGHT AND THE ASSOCIATED
COLD FRONT MOVES ACROSS NORTHWEST UTAH. A SECOND SHORTWAVE TROUGH
THEN MOVES ACROSS THE AREA LATE IN THE DAY ON MONDAY AND HELPS TO
PUSH THE FRONT INTO SOUTHERN UTAH. ALTHOUGH THE AIRMASS DRIES OUT A
BIT...THESE STORMS COULD STILL PRODUCE A FEW SHOWERS FOR MONDAY.

A DRIER AIRMASS THEN SETTLES OVER THE AREA WITH MORE SEASONABLE
TEMPERATURES THROUGH LATE IN THE WEEK.

WILL UPDATE ZONES TO TWEAK WORDING FOR SKY/WINDS TONIGHT...OTHERWISE
NO SIGNIFICANT CHANGES TO CURRENT FORECAST.

&&

.FIRE WEATHER...WINDS HAVE DECREASED THIS EVENING ACROSS MOST OF THE
FIRE DISTRICT...SO RED FLAG WARNING HAS BEEN ALLOWED TO EXPIRE.
HOWEVER...HUMIDITIES REMAIN RATHER LOW ACROSS NORTHWEST AND
WEST-CENTRAL UTAH AND POOR OVERNIGHT RECOVERIES CAN BE EXPECTED.
HUMIDITIES ARE EXPECTED TO INCREASE TOMORROW...MAINLY OVER SOUTHERN
AND EASTERN UTAH WITH AN INCREASE IN SHOWER ACTIVITY. A COOLER
AIRMASS WILL THEN SETTLE OVER THE AREA THROUGH MIDWEEK...BUT
HUMIDITIES WILL ONCE AGAIN TREND DOWNWARD.

&&

.AVIATION...SOUTH WINDS WILL PREVAIL OVER THE SLC TERMINAL THROUGH
TOMORROW MORNING. WINDS WILL INCREASE AGAIN LATE TOMORROW MORNING.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...NONE.
WY...NONE.
