AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
447 AM MDT FRI JUL 2 2010

.SYNOPSIS...WARM SOUTHWEST FLOW WILL CONTINUE ACROSS UTAH TODAY.
MOISTURE OVER EASTERN UTAH WILL LINGER INTO TONIGHT THEN SHIFT
EAST SATURDAY. A COLD FRONT WILL CROSS NORTHERN UTAH TONIGHT THEN
STALL ON SATURDAY. THE FRONT WILL CROSS THE REST OF THE AREA
SUNDAY.

&&

.DISCUSSION...THE UPPER TROF OVER THE PACNW IS BEGINNING TO SHIFT
INLAND TODAY. THIS WILL STRENGTHEN THE SOUTHWEST WINDS ALOFT
SOMEWHAT OVER THE CWA CREATING WINDY CONDITIONS ACROSS MOST OF
THE AREA AS THEY MIX DOWN. SPEEDS WILL MARGINALLY REACH ADVISORY
LEVELS IN A FEW SPOTS BUT DONT EXPECT THEM TO BE QUITE WIDESPREAD
ENOUGH FOR A WIND HIGHLIGHT.

THE MOISTURE BOUNDARY ACROSS THE CWA IS BEGINNING TO RETREAT EAST
BUT THERE SHOULD BE SUFFICIENT MOISTURE REMAINING ACROSS ERN UT
FOR ANOTHER ROUND OF CONVECTION TODAY. THE SLIGHTLY DRIER AIRMASS
AND THE INCREASED SURFACE WINDS WILL RESULT IN STRONGER WINDS FROM
STORMS TODAY AND HAVE ADDED THIS TO THE FORECAST.

WINDS AND RH ARE EXPECTED TO REACH CRITICAL LEVELS IN ALL FIRE
WEATHER ZONES WITH CRITICAL FUELS AND THE RED FLAG WARNING HAS
BEEN EXPANDED ACCORDINGLY.

THE FRONT ARRIVES IN NORTHWEST UT LATE TODAY THEN MOVES SLOWLY
SOUTH THROUGH ABOUT MIDDAY SAT WHEN IT STALLS ACROSS NORTH CENTRAL
UT. SOME MOISTURE POOLS ALONG THE FRONT FOR SOME CLOUDINESS BUT
DONT EXPECT MUCH IF ANY PRECIP. MOST OF THE REMAINING MOISTURE
GETS PUSHED OUT OF THE CWA BY THE MORE WESTERLY FLOW.

THE FRONT GETS PUSHED SOUTH AGAIN BY AN UPSTREAM SHORT WAVE TROF
THAT DROPS INTO THE GREAT BASIN SUN. THIS ALSO BRINGS SOME
INCREASE IN INSTABILITY WITH THE UPPER COOL POOL AND A SLIGHTLY
GREATER THREAT OF PRECIP...MAINLY SUN MORNING.

DRY STABLE WEST TO NORTHWEST FLOW IS EXPECTED MON WITH A LITTLE
DRY HIGH BASED CONVECTION TUE UNDER DEFORMATION. THE EC CONTINUES
TO BRING MOISTURE BACK NORTH INTO THE FORECAST AREA STARTING WED
WHILE THE GFS IS HAVING RUN TO RUN CONSISTENCY ISSUES ON THE
EVOLUTION OF THE WEAK FLOW OVER THE WESTERN US AFTER TUE. HAVE
LEANED HEAVILY TOWARDS THE EC IN THE 4-7 DAY PERIOD DUE TO BETTER
RUN TO RUN CONSISTENCY AND PAST PERFORMANCE.

&&

.AVIATION...SOUTH WINDS WILL CONTINUE AT THE SLC TERMINAL THROUGH
MID MORNING THEN BECOME STRONG AND GUSTY AFTER ABOUT 16Z. VFR
CONDITIONS WILL PREVAIL UNDER CLEAR SKIES.

&&

.FIRE WEATHER...STORM SYSTEM CURRENTLY OVER THE PACIFIC NORTHWEST
WILL MOVE INTO THE DISTRICT TONIGHT...BRINGING A COLD FRONT
THROUGH NORTHERN UTAH BY SATURDAY AND THROUGH MUCH OF THE STATE BY
SUNDAY. AHEAD OF THE SYSTEM...SOUTHWESTERLY FLOW WILL CONTINUE TO
INCREASE TODAY...RESULTING IN AREAS OF STRONG WINDS. VERY LOW
RELATIVE HUMIDITIES WILL CONTINUE OVER WESTERN UTAH AND SPREAD
INTO SOUTHERN UTAH AS THE AIRMASS CONTINUES TO DRY...RESULTING IN
SEVERE FIRE WEATHER CONDITIONS WHERE FUELS ARE CRITICALLY DRY. AS
THE FRONT MOVES THROUGH NORTHERN UTAH TONIGHT...WINDS WILL
DECREASE BEHIND IT AND TEMPERATURES WILL COOL. HOWEVER...WINDY
CONDITIONS ARE EXPECTED AHEAD OF THE FRONT ON SATURDAY OVER
SOUTHERN UTAH...AND AREAS OF CRITICAL FIRE WEATHER CONDITIONS ARE
A POSSIBILITY THERE ONCE AGAIN. AS THE FRONT MAKES ITS THROUGH THE
REST OF THE STATE BY SUNDAY...WINDS WILL CONTINUE TO
DECREASE...ENDING THE THREAT OF SEVERE FIRE WEATHER CONDITIONS.
HIGH PRESSURE IS EXPECTED TO REDEVELOP OVER THE DISTRICT FOR EARLY
NEXT WEEK.
