405 PM MDT SAT JUN 11 2005

.SYNOPSIS...UPPER LEVEL TROUGH WILL MOVE EAST ACROSS UTAH TONIGHT...
FOLLOWED BY A SECOND SYSTEM ACROSS NORTHERN UTAH SUNDAY. A RIDGE OF
HIGH PRESSURE TO OUR WEST WILL LEAD TO A WARM AND GENERALLY DRY
SOUTHWEST FLOW ALOFT THROUGH MUCH OF NEXT WEEK.

&&

.DISCUSSION...ACTIVE CONVECTION OVER MOST SECTIONS OF THE STATE THIS
AFTERNOON ASSOCIATED WITH THE UPPER TROUGH CURRENTLY OVER EXTREME WRN
UTAH. STRONG CONVECTION LATE THIS AFTERNOON...PRIMARILY WITH LOCALLY
HEAVY RAIN...EXISTS OVER SW THROUGH S/CNTRL UT. MOVEMENT OF THE
INDIVIDUAL CELLS HAS PICKED UP THE LAST HOUR OR SO...THUS THE
THREAT OF LOCALLY HEAVY RAIN AND MINOR FLOODING HAS DIMINISHED
SOMEWHAT.  KEEPING AN EYE ON THE LINE OF STORMS MOVING THROUGH WRN
MILLARD THROUGH EXTREME NW WASHINGTON COUNTY.  STRONG WINDS A GOOD
BET WITH THIS LINE...WITH THE THREAT OF LARGE HAIL FROM THE SRN END
OF THE LINE FOR WRN IRON/WASHINGTON COUNTIES.

UP NORTH THE VORTICITY MAX SOMEWHAT LOST UNDER THE CIRRUS SHIELD
OVER EXTREME NE NV WILL DRIFT EAST ACROSS NRN UT WITH THE TROUGH
OVERNIGHT.  MOISTURE FEEDING NORTH FROM THE CONVECTION OVER
SW/CNTRL UT WILL PRIME THE AIRMASS...AND LEAD TO DECENT...BUT NOT
EXCESS RAINFALL TONIGHT.  THE SECONDARY SHORTWAVE THAT WILL FOLLOW
OUT OF THE NW SUNDAY WILL FIND PLENTY OF MOIST AND UNSTABLE OVER NRN
UT.  DYNAMIC AND JET SUPPORT WILL REMAIN THE BEST OVER OUR FAR NRN
ZONES...WITH DIFFERENTIAL HEATING GENERATING SOME CONVECTION OVER
THE CNTRL MOUNTAINS SUNDAY AFTERNOON.

BUILDING HEIGHTS MONDAY WILL SIGNAL THE BEGINS OF WHAT COULD BE
A RETURN TO SEASONAL TEMPS NEXT WEEK.  THE RIDGE AXIS WILL SETTLE
TO THE EAST OF UTAH...LEAVING THE STATE IN A WARM AND GENERALLY DRY
SW FLOW FOR SEVERAL DAYS.  SUBTROPICAL DISTURBANCES CAUGHT UP IN
THE FLOW MAY GENERATE SOME CONVECTION...ESPECIALLY AS THE WEEK
PROGRESSES.

THE RATHER DEEP TROUGH THAT SITS OVER THE ERN PACIFIC MUCH OF THE
WEEK IS PROGGED TO MAKE A MOVE TO THE COAST BY THE END OF THE
WEEK. LOWERING HEIGHTS WITH THE APPROACHING TROUGH SIGNALS AN
INCREASED THREAT OF CONVECTION AND COOLER TEMPS HEADING INTO NEXT
WEEKEND.

&&

.AVIATION...GENERAL SOUTHERLY WINDS EXPECTED THIS EVENING...THOUGH
CONVECTION WILL CREATE ERRATIC AND GUSTY WINDS FROM NEARBY
CONVECTION. CEILINGS COULD DROP INTO THE MVFR RANGE IN HEAVIER
SHOWERS/STORMS THROUGH THIS EVENING.

RAIN AREAS ARE HANDLING THE RUNOFF...THOUGH MINOR SMALL STREAM AND
STREET FLOODING HAS BEEN REPORTED.  A SECONDARY...AND WELL
ORGANIZED CONVECTIVE BAND WILL MOVE ACROSS SW UT LATE THIS AFTERNOON
THROUGH EARLY EVENING.  THIS BAND PRODUCING STRONG CONVECTION...AND
IS MOVING SLOW ENOUGH THAT IT COULD PRODUCE MINOR FLASH FLOODING
