AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
415 PM MDT SUN JUN 5 2005

.SYNOPSIS...AN UPPER LEVEL LOW PRESSURE SYSTEM WILL REMAIN OVER THE
PACIFIC NORTHWEST THROUGH TUESDAY.  THIS UPPER LOW WILL EJECT A
SERIES OF WEATHER DISTURBANCES ACROSS NORTHERN UTAH THROUGH MIDWEEK.

&&

.DISCUSSION...UPPER LOW CURRENTLY OVER THE PACIFIC NW COAST SHOULD
REMAIN IN PLACE THROUGH MONDAY....THEN EXPAND EAST INTO THE NRN
ROCKIES MONDAY NIGHT/TUESDAY.  A SERIES OF VORTICITY MAXES WILL
ROTATE THROUGH THE UPPER LOW AND ACROSS THE NRN/CNTRL ROCKIES
THROUGH MIDWEEK.

THE SURFACE TROUGH ACROSS CNTRL NV...THROUGH EXTREME NW UT...THEN
NORTH ACROSS ERN ID HAS BECOME THE FOCUS OF CONVECTION THIS
AFTERNOON.  COOLER LOW-LEVEL AIR WILL MERGE WITH THE SURFACE TROUGH
BY EARLY THIS EVENING.  THE FIRST SHORTWAVE ROTATING E-NE THROUGH
NV WILL KICK THIS NOW COLD FRONT ACR0SS NW UT TONIGHT...THEN INTO
CNTRL UT WHERE IT WILL STALL ON MONDAY AFTERNOON.  CONVECTION WILL
PROBABLY STAY CLOSE TO THE FRONT OVER NW UT WHERE THE UPPER DYNAMICS
AND JET SUPPORT ARE FAVORABLE TONIGHT.

THE FOCUS OF PRECIP MONDAY/MONDAY EVENING WILL PROBABLY STAY NORTH
OF THE STALLED SURFACE FRONT IN VICINITY OF THE NEAR 700 MB THERMAL
BOUNDARY.  SHORTWAVES RIPPLING ALONG THIS BOUNDARY COMBINED WITH
CONVERGENCE ALONG THE THERMAL BOUNDARY AND JET SUPPORT SHOULD
GENERATE FAIRLY WIDESPREAD PRECIP IN THE COOL SECTOR BEHIND THE
FRONT.

SOME QUESTION FOR TUESDAY AS TO JUST HOW FAR SOUTH PRECIP WILL
DEVELOP.  THE TRACK OF WHAT LOOKS TO BE A RATHER ENERGETIC
SHORTWAVE IS IN DISPUTE BETWEEN THE GFS AND NAM.  THE GFS TAKES THIS
FEATURE FURTHER NORTH...WHICH WOULD CONFINE PRECIP TO EXTREME NRN
UT.  THE NAM IN CONTRAST IN FURTHER SOUTH OVER CNTRL UT.  AT TIME
WOULD PREFER THE NAM SOLUTION AS THE JET SUPPORT ON THE WEST SIDE OF
THE SHORTWAVE SUPPORT EITHER EASTWARD PROPAGATION...OR EVEN SOME
DIGGING...THROUGH CNTRL NV.

HANG BACK TROUGH THURSDAY/FRIDAY SHOULD BE SUFFICIENT TO MAINTAIN A
THREAT OF SHOWERY PRECIP OVER THE MOUNTAINS AND NRN ZONES.  THE
CORE OF THE WESTERLIES BEGIN TO WORK NORTH OF UTAH FRIDAY AND
BEYOND. EMBEDDED SHORTWAVES COULD BRING LIGHT PRECIP TO THE FAR NRN
ZONES...AS WELL AS KEEP TEMPS DOWN A BIT UP NORTH.  SRN ZONES WILL
SEE A WARMING TREND DURING THE EXTENDED PERIOD.

&&

.HYDRO...HIGH FLOWS WILL CONTINUE ALONG WATERWAYS ACROSS THE STATE
UNTIL FURTHER NOTICE.  CHANCE FOR HEAVY RAINS IN THE NORTH LATE
SUNDAY NIGHT AND MONDAY...POSSIBLY EXTENDING INTO CNTRL AND NE UT
TUESDAY.

&&

.AVIATION...SURFACE COLD FRONT CURRENTLY MOVING THROUGH NEVADA IS
EXPECTED TO ARRIVE AT SLC AROUND 04Z TONIGHT.  WILL HAVE TO KEEP AN
EYE ON THE POSSIBLE FORMATION OF AN OUTFLOW DEVELOPING FROM ONGOING
CONVECTION OVER NORTHEAST NEVADA.  THIS WOULD LIKELY BRING A
WINDSHIFT INTO SLC AHEAD OF THE MAIN FRONTAL BOUNDARY...AND AS MUCH
AS A COUPLE OF HOURS AHEAD. AT THIS TIME CONVECTION DOESNT LOOK
STRONG ENOUGH TO PRODUCE A SIGNIFICANT OUTFLOW. 00Z TAF WILL REFLECT
A GRADUAL VEERING OF THE WINDS TO THE SOUTHWEST THIS EVENING...THEN
TO WEST AROUND 03Z BEFORE SHIFTING TO NORTHWEST AT 04Z.  SH AND TS
LIKELY ALONG AND JUST BEHIND THE FRONT...THEN MODELS SHOW FRONT AND
WX RETREATING TO THE NORTHWEST AND WINDS BECOMING SOUTHERLY BY
MORNING.

&&

.FIRE...SOUTHWEST FLOW COUPLED WITH A STRONG SURFACE PRESSURE
GRADIENT WILL CONTINUE TO CREATE WINDY AND DRY CONDITIONS OVER
EXTREME SOUTHWEST UTAH TONIGHT AND MONDAY. THE COMBINATION OF GUSTY
WINDS...POOR OVERNIGHT RECOVERIES FOLLOWED BY LOWER HUMIDITY ON
MONDAY AND DRY FINE FUELS BELOW 6500 FEET IN EXTREME SOUTHERN UTAH
WILL LEAD TO CONTINUED HAZARDOUS FIRE WEATHER CONDITIONS. THE RED
FLAG WARNING HAS BEEN EXTENDED THROUGH TONIGHT AND MONDAY.

&&

.SLC WATCHES/WARNINGS/ADVISORIES...
UT...FLOOD WARNING SEVIER RIVER FROM HEADWATERS TO AURORA.
  ...RED FLAG WARNING EXTREME SW UTAH FIRE WX ZONES THIS
     AFTERNOON THRU THIS EVENING.
  ...WIND ADVISORY THIS EVENING WESTERN VALLEYS AND DESERTS...
     INCLUDING SALT LAKE AND TOOELE VALLEYS.
