AREA FORECAST DISCUSSION...UPDATED AVIATION SECTION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
1230 PM MDT THU JUN 8 2006

.SYNOPSIS...A MOIST SOUTHERLY FLOW WILL BE OVER THE AREA THROUGH
FRIDAY. A WEAKENING COLD FRONT WILL APPROACH THE AREA FROM THE
NORTHWEST THIS AFTERNOON AND THEN SWEEP THROUGH FRIDAY NIGHT.

&&

.DISCUSSION...LEADING EDGE OF THE PACIFIC TROUGH IS PUSHING INTO
CENTRAL NEVADA. THIS IS THE BEGINNING OF SIGNIFICANT DRYING ALOFT
FROM THE WEST. NOCTURNAL ELEVATED CONVECTION WAS ACTIVE OVERNIGHT IN
SOUTHWEST UTAH WHERE 2 WELL DEFINED VORT MAXES LIFTING UP FROM THE
SOUTH. SOME ACTIVITY CONTINUES AND IS MOVING OVER THE WESTERN
DESERTS AND SOUTHWEST UTAH THOUGH CIRCULATIONS ARE BEING SHEARED
APART AND WEAKENING WITH A SPEED MAX ALOFT MOVING THROUGH UTAH THIS
MORNING. HOWEVER WATER VAPOR LOOPS SUPPORT THIS CONVECTION
CONTINUING THIS MORING AS IT LIFTS NORTH. MEAN FLOW ALOFT IS VEERING
FROM THE SOUTH AND WILL CONTINUE TO TURN SOUTHWEST TODAY. WITH
MOISTURE AND INSTABILITY IN PLACE DESPITE SIGNIFICANT LOW LEVEL
COOLING OVERNIGHT (10C DOWN FROM 17C AT 700MB)...THERE SHOULD BE
ACTIVE AREAS OF THUNDERSTORMS TODAY IN THE SOUTH WHERE DISTURBANCES
WILL AID THE TERRAIN DESTABILIZATION AND IN THE NORTHWEST REGION
WITH THE APPROACHING SHORT WAVE TROUGH AND WEAK SHALLOW LOW LEVEL
BOUNDARY THIS AFTERNOON.

DRY MICROBURSTS THREAT REMAINS TODAY. BEST DEEP SHEAR OCCURS THIS
MORNING WITH THE 200MB JET SHIFTING EAST. BEST 850 TO 500 MB SHEAR
WILL BE IN THE NORTHWEST PART OF THE STATE THIS AFTERNOON AHEAD OF
THE SHORT WAVE TROUGH THAT PUSHES THE WEAK LOW LEVEL FRONT OR
OUTFLOW BOUNDARY INTO THE NORTHWEST PART OF UTAH. THIS COINCIDES
WITH THE LARGEST SURFACE BASED OR MEAN LAYER CAPE VALUES IN
NORTHWEST UTAH...THUS CONVECTION SHOULD BE ORGANIZED WITH TIME.
ISOLATED STRONG CELLS ALSO POSSIBLE IN PARTS OF SOUTHERN AND EASTERN
UTAH TODAY AS THEY GET SUPPORT FROM THE UPPER TROUGH APPROACHING.

MAIN PACIFIC TROUGH IS SPINNING OVER THE PACIFIC NORTHWEST AND
MOVING SLOWLY EAST. THIS WILL EJECT ANOTHER WAVE ACROSS NORTHERN
NEVADA AND INTO NORTHWEST UTAH LATE NIGHT. THUS EXPECT SIGNIFICANT
NOCTURNAL THUNDERSTORMS CONTINUE OVERNIGHT AND INTO FRIDAY MORNING
OVER THE NORTHWEST...AND AFFECTING THE WASATCH FRONT. SOME DRYING
WORKS INTO SOUTHERN UTAH ON FRIDAY BUT NOT ENOUGH TO END WIDELY
SCATTERED THUNDERSTORMS. WARMING IS FORECAST OVER UTAH ON FRIDAY AS
WELL AS THE MAIN PACIFIC TROUGH BOOSTS 700 MB TEMPS BACK TO 12-14C
OVER THE REGION. ORGANIZED CONVECTION WILL AGAIN MOVE ACROSS
NORTHERN AREAS FRIDAY AFTERNOON AND FRIDAY EVENING ASSOCIATED WITH
THE UPPER TROUGH AND LOW LEVEL BOUNDARY INTERACTING WITH THE
MOISTURE AND INSTABILITY IN PLACE. LOCALLY HEAVY RAIN AND STRONG
CELLS WITH THIS COMPLEX.

SIGNIFICANT DRYING OCCURS ON SATURDAY WITH THE TROUGH SHIFTING TO
THE NORTHEAST. LOW TO MID LEVEL BOUNDARY GETS LEFT OVER CENTRAL UTAH
WHICH MAY ALLOW ISOLATED CONVECTION TO REDEVELOP IN THE AFTERNOON
OTHERWISE A DRY DAY WITH NEAR 8C 700 MB TEMPS IN THE NORTH TO 14C IN
THE SOUTH. UPPER RIDGE BUILDS BACK OVER UTAH ON SUNDAY WITH
SOUTHERLY FLOW AND WARMING.

&&

.AVIATION...REMAINING OUTFLOW BOUNDARY HAS MOVED OVER KSLC WITHIN
THE LAST HOUR AND HAS KICKED UP WINDS A LITTLE STRONGER THAN
PREVIOUSLY EXPECTED. WINDS WILL REMAIN 15 TO 25 MPH WITH GUSTS TO 30
TO 35 MPH THROUGH 2000Z...AND THEN ARE EXPECTED TO DECREASE AS
CLOUDINESS INCREASES. THUNDERSTORMS ARE BEGINNING TO FIRE ALONG THE
OUTFLOW BOUNDARY TO THE NORTH OF KSLC AND HAVE 10% CHANCE OF
SHIFTING WINDS TO THE NORTH THROUGH 1930Z. BEST CHANCE FOR
THUNDERSTORMS AT KSLC APPEARS TO BE BETWEEN 23Z AND 02Z LATE THIS
AFTERNOON AND EARLY THIS EVENING. IN GENERAL...OUTFLOW WINDS FROM
THUNDERSTORMS SHOULD REMAIN FROM THE SOUTHWEST.

&&

.FIRE WEATHER...RELATIVE HUMIDITY HAS INCREASED GREATLY IN THE LAST
24 HOURS. RH IN THE DESERT AREAS IF SOUTHERN UTAH IS THE HIGHEST IT
HAS BEEN IN WEEKS. WET THUNDERSTORMS WILL TRACK FROM SOUTH TO NORTH
ACROSS THE ENTIRE AREA TODAY. BREEZY AND DRIER CONDITIONS RETURN
BEGINNING FRIDAY AFTERNOON.
