AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
940 AM MDT SAT JUL 26 2008

.SYNOPSIS...HIGH PRESSURE WILL REMAIN ACROSS THE REGION THROUGH
THE WEEKEND. A WEAK DISTURBANCE WILL MOVE ACROSS UTAH THIS MORNING
INTO THIS AFTERNOON. DRIER AIR WILL MOVE INTO NORTHERN UTAH SUNDAY
INTO MONDAY.

&&

.DISCUSSION...UPPER LEVEL HIGH PRESSURE REMAINS ACROSS THE REGION
THIS MORNING. A WEAK DISTURBANCE IS CURRENTLY MOVING THROUGH
PORTIONS OF SOUTHERN UTAH. THIS DISTURBANCE HAS HELPED TO DEVELOP
AN AREA OF SHOWERS AND ASSOCIATED CLOUD COVER ACROSS SOUTHERN UTAH
AND NORTHERN ARIZONA. UPDATED THE ZFP THIS MORNING TO ADJUST POPS
UPWARD THIS MORNING ACROSS SOUTHWEST AND SOUTH CENTRAL UTAH AND TO
INCREASE CLOUD COVER OVER MUCH OF SOUTHERN UTAH. EXPECT CLOUD
COVER TO THIN OUT LATER THIS MORNING INTO THIS AFTERNOON.

THE WEAK DISTURBANCE OVER SOUTHWEST UTAH WILL SLOWLY MOVE TO THE
NORTHEAST THROUGHOUT THE DAY. BY THE TIME OF MAXIMUM HEATING OF
THE DAY...THIS DISTURBANCE WILL LIKELY BE NEARING THE UINTA BASIN.
GIVEN THIS TRACK...AM A BIT CONCERNED CONVECTION WILL BE
SUPPRESSED DUE TO SUBSIDENCE BEHIND THE DISTURBANCE...ESPECIALLY
ACROSS PORTIONS OF NORTHERN AND CENTRAL UTAH. WILL MONITOR TRENDS
AND ADJUST THE FORECAST AS NECESSARY.

THE 12Z SLC SOUNDING INDICATED A PRECIPITABLE WATER VALUE OF 0.77
INCHES. WITH TEMPERATURES NEARING 100F ACROSS THE VALLEY LOCATIONS
OF NORTHERN UTAH...THERE MAY BE ENOUGH INSTABILITY TO ALLOW FOR
ISOLATED THUNDERSTORMS IF THEY ARE ABLE TO COUNTERACT THE
SUBSIDENCE BEHIND THE DISTURBANCE. ANY THUNDERSTORMS THAT FORM WILL BE
CAPABLE OF PRODUCING STRONG GUSTY WINDS THIS AFTERNOON AND EVENING
ACROSS NORTHERN AND PARTS OF CENTRAL UTAH. IN ADDITION...WITH DEEP
MOISTURE ACROSS SOUTHERN UTAH...EXPECT SOME LOCATIONS WILL RECEIVE
HEAVY RAINFALL IN THUNDERSTORMS. WHILE A FLASH FLOOD WATCH HAS NOT
BEEN ISSUED...ISOLATED FLASH FLOODING IS POSSIBLE ESPECIALLY IN
SLOT CANYONS AND NORMALLY DRY WASHES ACROSS SOUTHERN UTAH.

&&

.AVIATION...SOUTHERLY WINDS ARE EXPECTED TO BECOME GUSTY THIS
MORNING AT THE SLC TERMINAL. WINDS ARE FORECAST TO SHIFT TO THE
NORTHWEST BETWEEN 19-21Z THIS AFTERNOON...WITH A 10 PERCENT CHANCE
THE SHIFT WILL BE AS LATE AS 22Z.

ISOLATED THUNDERSTORMS ARE POSSIBLE ACROSS THE WASATCH FRONT THIS
AFTERNOON. ANY THUNDERSTORMS THAT IMPACT THE TERMINAL WILL LIKELY
HAVE GUSTY AND ERRATIC WINDS.

&&

.FIRE WEATHER...MOISTURE WILL REMAIN IN PLACE ACROSS THE SOUTHERN
AND EASTERN PORTIONS OF THE FIRE DISTRICT TODAY WHILE DRIER AIR WILL
REMAIN OVER THE FAR NORTHWEST. ANY STORMS OVER THE SOUTHEAST TODAY
WILL LIKELY PRODUCE WETTING RAINS BUT THE NORTH LACKS THE DEEP
MOISTURE TO PRODUCE MUCH WETTING RAIN ALTHOUGH ENOUGH HAS SPREAD UP
TO SET OFF ISOLATED AFTERNOON THUNDERSTORMS. ISOLATED DRY LIGHTNING
COULD BE A CONCERN ALONG WITH MICROBURST WINDS OVER THE WEST DESERTS
AND ALONG THE WASATCH FRONT. THIS GENERAL PATTERN WILL PERSIST
SUNDAY AND POSSIBLY MONDAY. THE AIRMASS WILL THEN DRY FROM THE
NORTHWEST ACROSS THE DISTRICT INTO THE MIDDLE OF NEXT WEEK.

&&

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

&&

PUBLIC/AVIATION...KRUSE
FIRE WEATHER...WILENSKY
