AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
948 AM MDT THU AUG 4 2011

.SYNOPSIS...A DRYING TREND WILL BEGIN ACROSS THE AREA TODAY WITH
A MUCH DRIER AIRMASS SPREADING INTO THE REGION ON FRIDAY AND
LASTING INTO EARLY NEXT WEEK.

&&

.DISCUSSION...MOSTLY SUNNY SKIES HAVE DEVELOPED ACROSS THE AREA
THIS MORNING...AS THE ISOLATED SHOWERS FROM EARLIER THIS MORNING
HAVE CLEARED OUT OF THE FAR SOUTHEAST AND NORTHWEST CORNERS OF THE
CWA. DRIER AIR WILL BEGIN TO MOVE INTO THE AREA FROM THE WEST
TODAY AS A PACIFIC TROUGH SLIDES THROUGH THE GREAT BASIN TODAY AND
TONIGHT. DRYING BEGINNING THIS AFTERNOON WILL BE DRAMATIC...WITH THE
NAM FORECASTING PRECIPITABLE WATER VALUES AS LOW AS 0.25 INCHES
MOVING INTO FAR WESTERN UTAH BY 00Z FRIDAY. HOWEVER...RELATIVELY
DEEP MOISTURE WILL STILL REMAIN IN PLACE OVER THE MAJORITY OF THE
CWA THROUGH THIS AFTERNOON...WITH PW VALUES GENERALLY 0.6 TO 0.9
INCHES ACROSS THE AREA...AND EVEN HIGHER VALUES IN FAR EASTERN
UTAH. AS SUCH...ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS
ARE POSSIBLE ACROSS THE ENTIRE CWA TODAY...BUT THE FOCUS IS
EXPECTED TO REMAIN IN THE EASTERN HALF.

THE DRIER AIRMASS IS EXPECTED TO SPREAD INTO PRETTY MUCH THE
ENTIRE CWA BY 12Z FRIDAY...GREATLY RESTRICTING ANY CONVECTIVE
DEVELOPMENT FRIDAY THROUGH AT LEAST THE BEGINNING OF NEXT WEEK.
BOTH THE GFS AND ECMWF KEEP A DRY AND STABLE ZONAL FLOW OVER THE
REGION THROUGH THE NEXT WORK WEEK...WITH THE 00Z ECMWF HINTING
THAT MONSOONAL MOISTURE MAY RETURN FOR THE WEEKEND OF AUGUST 13TH.

ISSUED A SMALL UPDATE TO THE FORECAST THIS MORNING TO LOWER CLOUD
COVER AND POPS FOR THE REST OF THE MORNING. OTHERWISE...THE
FORECAST LOOKS GOOD AND NO FURTHER UPDATES ARE ANTICIPATED.

&&

.AVIATION...THE SLC TERMINAL WILL SEE VFR CONDITIONS THROUGHOUT THE
DAY. SOUTHERLY WINDS ARE EXPECTED TO PERSIST ALL DAY...BUT THERE IS
A 20 PERCENT CHANCE THAT NEARBY SHOWERS WILL RESULT IN PERIODS OF
GUSTY/AND OR ERRATIC WINDS...PRIMARILY BETWEEN 21Z AND 02Z.

&&

.FIRE WEATHER...DRIER AIR WILL BEGIN TO MAKE ITS WAY INTO WESTERN
UTAH TODAY...THOUGH DEEP MOISTURE WILL STILL REMAIN OVER THE EASTERN
HALF OF THE DISTRICT. WITH DECREASING MOISTURE...COVERAGE OF
AFTERNOON CONVECTION WILL BE A BIT LESS THAN YESTERDAY...ESPECIALLY
OVER WESTERN UTAH. STILL...SCATTERED SHOWERS AND THUNDERSTORMS ARE
EXPECTED OVER THE EASTERN HALF OF THE DISTRICT.

SOUTHWEST WINDS WILL INCREASE TODAY OVER AN APPROACHING STORM
SYSTEM. WINDS COULD BECOME GUSTY ENOUGH TODAY TO PRODUCE ISOLATED
RED FLAG CONDITIONS OVER SOUTHWEST UTAH...THOUGH FUELS ARE NOT
CRITICAL AT THIS TIME. THE STORM SYSTEM WILL GRAZE NORTHERN UTAH
TONIGHT AND TOMORROW MORNING...AND WINDS TOMORROW ARE EXPECTED TO BE
LIGHTER. SO DESPITE THE INCREASINGLY DRY AIRMASS...CRITICAL FIRE
WEATHER CONDITIONS ARE NOT ANTICIPATED FRIDAY THROUGH THE WEEKEND.

&&

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