AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
935 PM MDT THU JUL 9 2009

.SYNOPSIS...HIGH PRESSURE WILL CONTINUE BUILD EAST OF THE AREA
THROUGH THE WEEKEND...ALLOWING MOISTURE TO INCREASE ACROSS UTAH FROM
THE SOUTH. AN UPPER LEVEL DISTURBANCE WILL GRAZE THE NORTHERN
SECTIONS OF THE FORECAST AREA ON MONDAY.

&&

.DISCUSSION...A DRY SOUTHWEST FLOW WILL REMAIN OVER THE REGION
THROUGH TONIGHT...RESULTING IN MOSTLY CLEAR SKIES ACROSS THE CWA.
A STRONG MOISTURE GRADIENT EXISTS TO THE SOUTHEAST...AND AS THE FLOW
BACKS TO SOUTHERLY ACROSS ARIZONA TOMORROW...EXPECT THE MOISTURE TO
PUSH INTO SOUTHERN UTAH. HOWEVER...BUFR SOUNDINGS ARE NOT
PARTICULARLY UNSTABLE...SO SLIGHT CHANCE MENTION OF THUNDERSTORMS IN
CURRENT FORECAST SEEMS FINE. HOWEVER...ANY THUNDERSTORMS TOMORROW
COULD PRODUCE GUSTY WINDS AND LITTLE RAINFALL.

MOISTURE WILL CONTINUE TO SPREAD ACROSS THE AREA SATURDAY AND LINGER
INTO SUNDAY. THIS WILL BRING INCREASED COVERAGE OF THUNDERSTORMS TO
THE AREA. IN ADDITION...A WEAK SHORTWAVE DISTURBANCE IS PROGGED TO
CROSS THE AREA ON SATURDAY...PROVIDING SOME ADDITIONAL LIFT FOR
THUNDERSTORM DEVELOPMENT. ON SUNDAY...A JET STREAK WILL MOVE ACROSS
NORTHWEST UTAH AND COULD BRING BETTER ORGANIZATION TO ANY
THUNDERSTORMS THAT DEVELOP ACROSS THE NORTH.

THE UPPER LOW CURRENTLY OVER THE PACIFIC NORTHWEST WILL THEN EJECT
INLAND AND BRUSH NORTHERN UTAH ON MONDAY...PUSHING A COLD FRONT INTO
THE AREA. THIS WILL ALSO SPREAD DRIER AIR IN FROM THE WEST. A RIDGE
WILL THEN BUILD OVER THE AREA FOR THE MIDDLE PART OF NEXT
WEEK...RETURNING HOT AND DRY CONDITIONS TO THE AREA.

WILL UPDATE TO REDUCE CLOUD COVER IN A FEW ZONES FOR TONIGHT.

&&

.AVIATION...NORTHERLY WINDS WILL CONTINUE AT THE SLC TERMINAL
THROUGH ABOUT 05Z TONIGHT AT WHICH TIME A TRANSITION TO SOUTHEAST IS
EXPECTED. SOUTH WINDS ARE EXPECTED THROUGH FRIDAY AFTERNOON WITH
ONLY A 20 PERCENT CHANCE OF SWITCHING TO NORTHWEST AFTER 21Z FRIDAY.

&&

.FIRE WEATHER...BREEZY SOUTHWEST WINDS ARE DECREASING THIS EVENING
AND HAVE MOSTLY FALLEN BELOW CRITICAL LEVELS...SO WILL ALLOW THE RED
FLAG WARNING TO EXPIRE. THE FLOW BECOMES A BIT MORE SOUTHERLY FRIDAY
AND MOISTURE WILL START TO INCREASE ACROSS THE REGION. THIS WILL
BRING A THREAT OF MAINLY HIGH BASED THUNDERSTORMS TO SOUTHERN UTAH
FRIDAY. THESE WILL SPREAD NORTHWARD SATURDAY WHILE STORMS OVER THE
SOUTH BECOME SOMEWHAT WETTER. THE THREAT OF SHOWERS AND
THUNDERSTORMS CONTINUES INTO SUNDAY THEN SLOW DRYING IS FORECAST FOR
NEXT WEEK. HUMIDITIES WILL REMAIN LOW FRIDAY THEN RISE THROUGH THE
WEEKEND.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
