AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
915 AM MDT SAT JUN 19 2010

.SYNOPSIS...A MILD AND DRY WEST SOUTHWESTERLY FLOW WILL REMAIN IN
PLACE INTO EARLY NEXT WEEK.

&&

.DISCUSSION...TODAY LOOKS TO BE ANOTHER CLEAR...SUNNY DAY ACROSS
THE CWA AS DRY SOUTHWESTERLY FLOW CONTINUES ACROSS THE AREA.
UPDATED THE FORECAST THIS MORNING TO DECREASE CLOUD COVER ACROSS
THE NORTHWEST CORNER OF THE CWA AS THE SHORTWAVE THAT CLIPPED THE
NORTHERN PART OF THE CWA HAS MOVED OFF TO THE NORTHEAST.

MODELS SHOW MODEST CAPE AND LIFTED INDEX VALUES BETWEEN -2 AND -3
ACROSS THE NORTHERN PART OF THE CWA THIS AFTERNOON. HOWEVER...WITH
SUCH LIMITED MOISTURE AVAILABLE...DOUBT THAT LITTLE WILL COME OF
THE INSTABILITY OTHER THAN SOME ISOLATED BUILDUPS ACROSS THE
HIGHER TERRAIN THIS AFTERNOON.

SOUTHWESTERLY FLOW WILL CONTINUE TO INCREASE ACROSS THE CWA AHEAD
OF A SYSTEM MOVING INTO THE PACIFIC NORTHWEST. THIS
DRY...SOUTHWESTERLY FLOW COMBINED WITH LOW HUMIDITY WILL RESULT IN
ANOTHER DAY OF SEVER FIRE WEATHER CONDITIONS WHERE FUELS ARE
CRITICAL IN SOUTHERN UTAH. SEE THE FIRE WEATHER SECTION FOR MORE DETAILS.

THE APPROACHING SYSTEM WILL BRUSH BY TO THE NORTH OF THE CWA EARLY
MONDAY. THIS WILL SEND A COLD FRONT ACROSS THE CWA MONDAY...BUT
WITH THE BULK OF THE MOISTURE WELL TO THE NORTH OF THE
CWA...LITTLE TO NO PRECIP IS EXPECTED WITH THIS FRONT.

BOTH THE GFS AND THE EC SHOW CALM...BENIGN WEATHER THROUGH THE END
OF NEXT WEEK...WITH HIGH PRESSURE BUILDING INTO THE AREA TUESDAY.
THE TWO MODELS DO HAVE SOME DISAGREEMENT NEAR THE END OF NEXT WEEK
AS TO HOW LONG THE RIDGE REMAINS IN PLACE OVER THE CWA.

&&

.AVIATION...GUSTY SOUTHERLY WINDS HAVE ALREADY DEVELOPED AT THE KSLC
TERMINAL AT MID-MORNING. A 70 PERCENT CHANCE EXISTS OF WINDS
REACHING AIRPORT WEATHER WARNING CRITERIA OF GUSTS GREATER THAN 30
MPH IN THE 17Z-22Z TIMEFRAME. CURRENT TAF DOES NOT HAVE A TYPICAL
DIURNAL WIND SWITCH TO NORTHWEST WINDS THIS AFTERNOON...BUT A 30
PERCENT CHANCE EXISTS THAT A SHALLOW NORTHWESTERLY LAKE BREEZE WILL
UNDERCUT THE GUSTY SOUTHERLIES IN THE 22Z-01Z TIMEFRAME. THE
SOUTHEAST DRAINAGE WINDS THAT DEVELOP THIS EVENING LOOK TO BE
ENHANCED...WITH SPEEDS RUNNING CLOSE TO 10-12 KTS TONIGHT. SKIES
WILL REMAIN CLEAR THROUGH THIS EVENING.

&&

.FIRE WEATHER...THE SURFACE TROUGH ACROSS ERN NV ALONG WITH
INCREASING SW FLOW ALOFT WILL RESULT IN BREEZY SOUTHERLY WINDS
ACROSS MOST SRN/WRN FIRE DISTRICTS TODAY. THE COMBINATION OF WIND
AND VERY LOW RH VALUES ACROSS THE SOUTH WILL RESULT IN HAZARDOUS
FIRE WEATHER CONDITIONS THIS AFTERNOON...AND LIKELY AGAIN SUNDAY.
A WEAK WEATHER DISTURBANCE MOVING EAST ACROSS NRN UTAH MONDAY WILL
SHAVE A FEW DEGREES OFF THE MAX TEMPS...WITH LITTLE AFFECT OF RH
VALUES. WINDS WILL SHIFT A BIT MORE TO THE WEST...THOUGH REMAIN
BREEZY ACROSS AT LEAST THE SRN HALF OF UTAH.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...RED FLAG WARNING UNTIL 9 PM MDT THIS EVENING BELOW 6500 FEET FOR
     UTAH FIRE WEATHER ZONES 439-440.
