AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
915 PM MST MON FEB 27 2006

.SYNOPSIS...A MILD AND STRONG SOUTHWEST FLOW AHEAD OF A LOW IN THE
EASTERN PACIFIC WILL REMAIN OVER UTAH THROUGH TUESDAY. THE LOW WILL
MOVE INLAND TUESDAY...WITH THE ASSOCIATED COLD FRONT MOVING INTO UTAH
TUESDAY AFTERNOON. WEAK HIGH PRESSURE WILL SETTLE OVER THE AREA
WEDNESDAY.

&&

.DISCUSSION...UPPER TROUGH SQUARELY ALONG 130W THIS EVENING STILL ON
TRACK TO REACH COAST EARLY TUESDAY...THEN WEAKEN AND LIFT NE THROUGH
THE GREAT BASIN LATE TUESDAY/TUESDAY NIGHT.

WINDS WILL BE THE MAIN ISSUE OVER THE NEXT 18-24 HOURS...ESPECIALLY
FOR THE WRN ZONES AND ACROSS THE MOUNTAINS.  INCREASING SW FLOW NEAR
700 MB AHEAD OF THE APPROACHING TROUGH COMBINED WITH A FAVORABLE
SURFACE GRADIENT WILL BRING FAIRLY STRONG SOUTH WINDS OVERNIGHT
THROUGH AT LEAST EARLY TUESDAY AFTERNOON. SOME CONCERN ABOUT STRONG
GUSTS WRN VALLEYS TONIGHT AS VIRGA OR LIGHT SHOWERS MAY DRAG THE LOW-
LEVEL JET TO THE SURFACE.  FOR NOW NOT PLANNING ON ANY WIND
HIGHLIGHTS...AND WILL LET THE FORECAST WORDING SUFFICE.

AGREE WITH THE VARIOUS MODEL SOLUTIONS THAT A NUMBER OF WEAK
SHORTWAVES WILL EJECT OUT AHEAD OF THE MAIN...BUT DECAYING TROUGH
TONIGHT THROUGH TUESDAY MORNING.  STILL APPEARS THAT THE BEST
THREAT FOR PRECIP WILL COME FROM ABOUT MIDAFTERNOON WITH THE ARRIVAL
OF THE SURFACE...THROUGH THE EVENING HOURS AS THE MID-LEVEL COLD
POOL MOVES INTO THE REGION. PRECIP SHOULD GRADUALLY DISSIPATE AFTER
MIDNIGHT AS THERMAL ADVECTION WANES AND THE REMNANT OF THE TROUGH
SLIDES OFF TO THE EAST.

THE PATTERN OVER THE ERN PACIFIC/WRN CONUS RELOADS FOR THE END OF
THE WEEK AS THE NEXT COLD TROUGH DROPS S-SE OUT OF THE GULF OF
ALASKA. SHORTWAVE RIDGE OVER THE AREA WEDNESDAY WILL BE REPLACED BY
AN INCREASINGLY STRONG SW FLOW ALOFT THURSDAY/THURSDAY NIGHT. TEMPS
SHOULD BOUNCE BACK A BIT FROM THEIR POST-FRONTAL READINGS OF
WEDNESDAY. BEST THREAT FOR THE NEXT ROUND OF PRECIP SHOULD BE FROM
FRIDAY AFTERNOON THROUGH AT LEAST SATURDAY MORNING.

NO UPDATE PLANNED FOR THE AFTERNOON PACKAGE THIS EVENING.

&&

.AVIATION...AIRMASS OVER KSLC SITE SHOULD REMAIN FAIRLY WELL MIXED
