AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
959 AM MDT MON JUL 16 2012

.SYNOPSIS...A DRYING TREND WILL BEGIN TODAY AND CONTINUE THROUGH
MID WEEK WITH DRIER CONDITIONS REMAINING IN PLACE INTO THURSDAY.
MOISTURE IS EXPECTED TO RETURN TO THE AREA LATE IN THE WEEK.

&&

.DISCUSSION...A FEW ISOLATED THUNDERSTORMS HAVE CONTINUE TO MOVE
ALONG THE UTAH/NEVADA BORDER THIS MORNING. THESE THUNDERSTORMS ARE
LIKELY ASSOCIATED WITH A SUBTLE SHORTWAVE FEATURING ROTATING
NORTHWARD.

CLEARING SKIES ARE PRESENT ACROSS MUCH OF THE CWA THIS MORNING.
BLENDED TPW IMAGERY INDICATES PW VALUES REMAIN BETWEEN 0.80 AND 1
INCH ACROSS THE MAJORITY OF THE CWA. WITH CLEARING SKIES ACROSS
MUCH OF THE AREA...EXPECT INSTABILITY TO INCREASE THIS MORNING
INTO EARLY THIS AFTERNOON.

SREF ENSEMBLE FORECASTS INDICATE THERE IS SUFFICIENT SHEAR ACROSS
THE AREA TO SUPPORT CONVECTION...WITH A FEW CELLS CAPABLE OF
ACHIEVING SOME ORGANIZATION. WITH SUFFICIENT MOISTURE...AT LEAST
MARGINAL INSTABILITY...AND SHEAR...EXPECT CONVECTION TO DEVELOP
LATER THIS MORNING INTO EARLY THIS AFTERNOON. ISOLATED FLASH
FLOODING REMAINS A THREAT...PARTICULARLY WITH ANY THUNDERSTORMS
THAT DEVELOP ACROSS SOUTHWESTERN UTAH. ALSO CANT RULE OUT A FEW
CELLS BEING CAPABLE OF PRODUCING SMALL HAIL.

DRIER AIR IS EXPECTED TO MOVE INTO THE AREA TONIGHT IN TUESDAY
BRINGING AN END TO THIS MONSOONAL SURGE. THE NEXT CHANCE FOR
ANOTHER MOISTURE SURGE APPEARS TO BE FRIDAY INTO SATURDAY.

&&

.AVIATION...GUSTY SOUTH WINDS CONTINUE AT THE SLC TERMINAL THIS
MORNING. EXPECT CONVECTION TO DEVELOP ACROSS NORTHERN UTAH LATER
THIS MORNING INTO EARLY THIS AFTERNOON. THERE IS A 20 PERCENT
CHANCE A THUNDERSTORM OR THE ASSOCIATED OUTFLOW WILL IMPACT THE
TERMINAL BETWEEN 21-00Z.

CANT RULE OUT A WIND SHIFT TO THE NORTHWEST BETWEEN 19-21Z THIS
AFTERNOON. WILL CONTINUE TO MONITOR TRENDS AND UPDATE THE TAF IF
NEEDED.

&&

.FIRE WEATHER...SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP
AGAIN THIS AFTERNOON. STORMS WILL INITIALLY FORM OVER THE HIGHER
TERRAIN...AND DRIFT OVER ADJACENT VALLEYS. WINDS WILL BE GUSTY AND
ERRATIC IN THE VICINITY OF ANY STORMS THAT FORM.
ADDITIONALLY...HEAVY RAIN AND LIGHTNING WILL ACCOMPANY STORMS.

SOUTHWEST FLOW ALOFT WILL CONTINUE TO INCREASE OVER THE NEXT 24
HOURS ALLOWING DRIER AIR TO NOSE IN FROM THE SOUTHWEST. THIS HAS
ALREADY BEGUN AT THE UPPER LEVELS AND WILL GRADUALLY TRANSITION
DOWN TO THE SURFACE ALLOWING LOWERING RELATIVE HUMIDITY AND
WARMER TEMPERATURES BEGINNING TUESDAY. DRY AND BREEZY CONDITIONS
CAN BE EXPECTED ACROSS THE WESTERN VALLEYS MIDWEEK. DRY AND WARM
CONDITIONS WILL CONTINUE THROUGH THE LATTER HALF OF THE WEEK WITH
ANY STORM DEVELOPMENT REMAINING ISOLATED AND PEGGED TO THE
TERRAIN ACROSS THE EASTERN HALF OF THE AREA.
