AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
240 PM MDT MON JUL 31 2006

.SYNOPSIS...AN UPPER TROUGH ALONG THE WEST COAST WILL KEEP A
MOIST SOUTHWEST FLOW OVER THE AREA INTO TUESDAY. THE TROUGH
WILL CROSS THE AREA TUESDAY AFTERNOON WITH A DRIER WESTERLY FLOW
SPREADING IN BEHIND IT FOR WEDNESDAY.

&&

.DISCUSSION...ILL DEFINED SHORT WAVES EJECTING OUT OF THE WEST COAST
TROF...A MOIST AIRMASS AND WEAK JET SUPPORT ARE COMBINING TO PRODUCE
SCATTERED THUNDERSTORMS THIS AFTERNOON. MODELS INDICATE THE FAR
SOUTHWEST CORNER WILL REMAIN QUIET AND SO FAR THAT IS HOLDING TRUE
BUT THE REST OF THE AREA WILL HAVE A THREAT OF STORMS WELL INTO THE
NIGHT. THE AIRMASS IS STILL MOIST ENOUGH FOR HEAVY RAIN WITH THE
STRONGER CELLS AND HAVE INCLUDED THIS IN THE FORECAST FOR TONIGHT.

AS THE WEST COAST TROF FILLS AND LIFTS INLAND LATER TONIGHT AND
TUE...THE SOUTHWEST FLOW OVER UTAH WILL DRY THE AREA OUT FROM THE
SOUTHWEST. IT SHOULD STILL BE FAIRLY ACTIVE OVER THE NORTH TOMORROW
WITH SUFFICIENT SHEAR AND DYNAMIC SUPPORT TO BRING A THREAT OF
STRONG STORMS WHILE ONLY ISOLATED CELLS ARE EXPECTED OVER THE
SOUTH...MAINLY THE MTNS AND ERN VALLEYS.

A WEAK SHORT WAVE RIDGE MOVES IN ON WED AND THIS...COMBINED WITH A
DRIER AIRMASS SHOULD SUPPRESS MOST CONVECTION.

THE EJECTING UPPER TROF LEAVES A WEAKNESS BACK ALONG THE
COAST. WEAK UPSTREAM FEATURES ARE FORECAST TO DROP INTO THIS TROF
POSITION AND REDEVELOP THE TROF ALONG THE COAST BY THE LATTER PART
OF THE WEEK. THIS BACKS THE FLOW OVER UT TO MORE SOUTHERLY AND
BRINGS MOISTURE BACK UP INTO MAINLY THE EAST BY NEXT WEEKEND.

TEMPS HAVE BEEN COOL TODAY OVER THE NORTH DUE TO THE MORNING CLOUD
COVER BUT ARE WARMING UP NOW THAT CLOUDS HAVE THINNED. A COOLER
AIRMASS DOES SPREAD INTO THE STATE TOMORROW WITH THE EJECTING TROF
AND WILL KEEP TEMPS DOWN BELOW NORMAL AGAIN TOMORROW...BRINGING A
NICE BREAK FROM THE HEAT OF THE LAST FEW WEEKS. TEMPS WILL RETURN TO
NEAR OR ABOVE NORMAL AFTER MID WEEK.

&&

.AVIATION...PLENTY OF MOISTURE AND INSTABILITY SHOULD ALLOW
THUNDERSTORMS TO DEVELOP OVER NORTHERN UTAH TODAY...ESPECIALLY AS
THE THICKER CLOUDS CLEAR OUT. THE KSLC TERMINAL WILL SEE A 30
PERCENT CHANCE OF THUNDERSTORMS TODAY...WITH THE BEST CHANCE OF
OCCURRENCE DURING THE 2200-0300Z TIMEFRAME. BRIEF HIGH-END MVFR
VISIBILITIES AND CIGS BETWEEN 6000-8000 FT ARE POSSIBLE WITH THE
STRONGER STORMS. OCCASIONAL RAIN SHOWERS WITH EMBEDDED THUNDERSTORMS
COULD CONTINUE THROUGH THE OVERNIGHT HOURS. WINDS AT KSLC ARE
EXPECTED TO MAINTAIN A NORTHWESTERLY DIRECTION THROUGH 0300-0400Z
THIS EVENING...ALTHOUGH SHOWERS AND THUNDERSTORMS WILL PRODUCE GUSTY
AND ERRATIC WINDS.

&&

.FIRE WEATHER...A MOIST AND UNSTABLE AIRMASS WILL BE OVER THE AREA
THROUGH TUESDAY. A DRIER WESTERLY FLOW DEVELOPS FOR WEDNESDAY AND
THURSDAY. A PLUME OF MOISTURE IS THEN EXPECTED TO BE OVER THE FOUR
CORNERS REGION THROUGH THE WEEKEND...LEADING TO WET THUNDERSTORMS
OVER THE MOUNTAINS AND EAST.

&&

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