AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
445 AM MDT THU AUG 10 2006

.SYNOPSIS...A GENERALLY DRY SOUTHWEST FLOW WILL EXIST OVER ALL BUT
EXTREME SOUTHERN UTAH TODAY. MOISTURE TO THE SOUTH OF THE STATE
WILL WORK SLOWLY NORTH OVER UTAH AHEAD OF A PACIFIC TROUGH THIS
WEEKEND.

&&

.DISCUSSION...A GENERALLY DRY W-SW FLOW ALOFT EXISTS OVER ALL BUT
THE EXTREME SRN PORTION UTAH THIS MORNING. RESIDUAL CLOUDINESS FROM
THE EVENING CONVECTION OVER THE SW MOUNTAINS SUGGESTS SOME
INSTABILITY STILL PRESENT OVER THE AREA. SUSPECT THAT CONVECTION
WILL GET AN EARLIER START OVER THE SW MOUNTAINS THIS MORNING...THEN
SPREADING EAST ACROSS SRN UTAH THROUGH THE AREA OF BEST MOISTURE.

THE PACIFIC TROUGH ALONG 130W WILL MOVE INLAND THROUGH THE PACIFIC
NW TONIGHT. THIS TROUGH WILL GRIND ITS WAY EAST FRIDAY/SATURDAY...
WITH THE MAIN COLD AIR AND DYNAMICS REMAINING JUST TO THE NORTH OF
UTAH.  THE MOISTURE OVER AZ/SRN UT WILL GRADUALLY WORK NORTH OVER
THE NEXT COUPLE OF DAYS.  THIS MOISTURE WILL ENCOUNTER A SERIES OF
WEAK VORTICITY MAX MOVING ENE THROUGH THE BASE OF THE TROUGH ACROSS
NW UT. THESE VORTICITY MAXIMA WILL TAP A LITTLE COOLER MID-LEVEL
AIR AS THEY MOVE ACROSS THE FAR NORTH. WEAK DYNAMICS/INSTABILITY
ALONG WITH ADEQUATE MOISTURE SHOULD PRODUCE SOME CONVECTION UP
NORTH THIS WEEKEND. SRN/CNTRL UTAH WILL REMAIN SOMEWHAT ACTIVE AS
DIURNAL CONVECTION A GOOD BET EACH DAY.

A WEAK HANG BACK TROUGH ALONG THE CA COAST EARLY NEXT WEEK WILL
TURN THE FLOW ALOFT A BIT MORE SOUTHERLY. THIS IN TURN WILL ALLOW
MOISTURE TO INCREASE NORTHWARD ACROSS THE GREAT BASIN. WEAK
DISTURBANCES EJECT NNE OUT OF THE TROUGH THROUGH NV/WRN UT SHOULD
BE ABLE TO GENERATE SOME ORGANIZED CONVECTION TO GO ALONG WITH THE
USUAL DIURNAL ACTIVITY FOR THE FIRST HALF OF THE WEEK. THE THREAT
FOR CONVECTION COULD PEAK LATE WEDNESDAY/THURSDAY AS THE TROUGH
MOVES EAST THROUGH THE BASIN.

&&

.AVIATION...AS A MODERATELY STRONG SYSTEM MOVES INTO OREGON TODAY
SURFACE PRESSURES WILL FALL ACROSS SOUTHWEST IDAHO INTO NORTHWEST
UTAH. RAPID PRESSURE FALLS OVER EXTREME NORTHWEST UTAH SOMETIMES
WILL PREVENT THE LAKE BREEZE FROM SETTING IN. THERE IS A 20 PERCENT
CHANCE OF THIS HAPPENING. THE ANTICIPATED RESULT WILL A DELAYED
ONSET OF A LAKE BREEZE UNTIL ABOUT 1500 MDT.

&&

.FIRE WEATHER...A FIRE WEATHER WATCH FOR DRY LIGHTNING HAS BEEN
ISSUED FOR WEST CENTRAL UTAH FOR LATE THIS AFTERNOON AND EVENING.
THE COMBINATION OF MID LEVEL MOISTURE AND UPPER LEVEL SUPPORT TO
DESTABILIZE THE AIRMASS WILL COME TOGETHER OVER THIS PORTION OF
UTAH. MICROBURST WINDS OF UP TO 40 MPH ARE POSSIBLE. ANOTHER AREA OF
CONCERN WILL BE THE GREAT SALT LAKE DESERT LATE TODAY WHERE LOW RH
AND SOUTH WINDS NEARING CRITICAL SPEEDS COULD DEVELOP.
