AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
949 PM MDT TUE APR 15 2014

.SYNOPSIS...THE COLD FRONT OVER CENTRAL UTAH AT MID-EVENING WILL
CONTINUE SOUTH THROUGH THE STATE OVERNIGHT. A SECOND WEAK STORM
SYSTEM WILL MOVE SOUTHEAST ACROSS THE STATE WEDNESDAY. HIGH
PRESSURE WILL REBUILD FOR THE END OF THE WORK WEEK AHEAD OF THE
NEXT WEAKENING STORM SYSTEM ARRIVING FOR FRIDAY NIGHT THROUGH
SATURDAY.

.DISCUSSION...THE SHORTWAVE MOVING EAST-SOUTHEAST THROUGH THE
NORTHERN ROCKIES THIS EVENING HAS GENERATED LITTLE MORE THAN
CLOUDS AND ISOLATED VERY LIGHT SHOWERS OVER THE NORTHERN MOUNTAINS
THIS EVENING. THE ASSOCIATED SURFACE COLD FRONT...CURRENTLY OVER
CENTRAL UTAH...IS NOT EXPECTED TO GENERATE ANY ADDITIONAL PRECIP
AS THE ASSOCIATED UPPER LEVEL TROUGH MOVES EAST AWAY FROM THE
FORECAST AREA OVERNIGHT.

A WEAK SECOND SHORTWAVE WILL TRACK A BIT FURTHER SOUTH THROUGH
UTAH ON WEDNESDAY. THIS NEXT FEATURE IS NOT EXPECTED TO PRODUCE
MUCH IN THE WAY OF LIFT AS THE ASSOCIATED THERMAL ADVECTION ALOFT
AND DYNAMIC SUPPORT APPEAR WEAK AND THE AIRMASS SOMEWHAT STABLE
BEHIND TONIGHTS COLD FRONT. ADDITIONAL COOL AIR WITH THE NEXT
FEATURE SHOULD SERVE TO KEEP TEMPS RUNNING NEAR OR A LITTLE BELOW
NORMAL FOR WEDNESDAY.

BUILDING HEIGHTS ACROSS THE INTERIOR WEST LATE IN THE WEEK WILL
BRING A COUPLE OF DAYS OF DRY AND WARM CONDITIONS TO THE STATE
THURSDAY/FRIDAY. THE NEXT PACIFIC TROUGH SCHEDULED TO REACH THE
WEST COAST THURSDAY NIGHT IS SHOWN TO SPLIT HARD AS IT MOVES
INLAND IN BOTH THE GFS AND ECMWF. THE WEAKEN OF THIS FEATURE AS IT
TRACKS THROUGH THE WESTERN CONUS WILL LIKELY LEAVE UTAH ON THE
SHORT END OF ANY PRECIP HEADING INTO THE FIRST HALF OF THE
WEEKEND.
