AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
911 PM MST MON FEB 18 2013

.SYNOPSIS...A LONG DURATION STORM SYSTEM WILL AFFECT THE REGION
TUESDAY NIGHT INTO THURSDAY. A SECOND SYSTEM WILL AFFECT MAINLY
THE NORTHERN THIRD OF UTAH LATE THURSDAY NIGHT THROUGH FRIDAY...
FOLLOWED A SUBSTANTIALLY COLDER STORM SYSTEM FOR THE UPCOMING
WEEKEND.

&&

.DISCUSSION...THE UPPER LEVEL TROUGH CURRENTLY ALONG THE PACIFIC
NORTHWEST COAST IS STILL ON TRACK TO SPIN-UP INTO A CLOSED LOW
OVER THE WESTERN/SOUTHERN GREAT BASIN TUESDAY NIGHT/EARLY
WEDNESDAY. THE 00Z GFS/12Z ECMWF REMAIN REMARKABLY SIMILAR IN THE
EVOLUTION OF THIS FEATURE AND THE TRACK EAST ACROSS NORTHERN
ARIZONA THROUGH EXTREME SOUTHERN UTAH. CONFIDENCE REMAINS HIGH
THAT A WIDESPREAD PRECIP EVENT IS ON TAP FOR MIDWEEK.

THE INITIAL ROUND OF HEAVY PRECIP WILL REMAIN OVER SOUTHERN AND
CENTRAL UTAH IN CLOSE PROXIMITY TO THE STRONGEST DYNAMIC LIFT AND
COLDER AIR ALOFT. THE DEEP SURFACE TROUGH ACROSS SOUTHERN UTAH
WILL MARK THE AREA OF THE HEAVIEST PRECIP WEDNESDAY THROUGH
WEDNESDAY EVENING. PRECIP ACROSS NORTHERLY UTAH...WHILE STILL
FAIRLY WIDESPREAD...WILL LIKELY REMAIN LIGHT DUE TO WEAK DYNAMIC
AND THERMALLY SUPPORTED LIFT THROUGH WEDNESDAY AFTERNOON.

A SHORT PERIOD OF HEAVIER ORGANIZED PRECIP COULD DEVELOP ACROSS
NORTHERN AND WESTERN UTAH LATER WEDNESDAY NIGHT THROUGH THURSDAY.
A SECONDARY DISTURBANCE FILLING IN BEHIND THE NOW EXITED UPPER LOW
WILL BRING IN INCREASED DYNAMIC LIFT AND SOMEWHAT COLDER AIR
ALOFT. WEAK LOW-LEVEL COLD ADVECTION SUPPORTED BY THE MID-LEVEL
DYNAMIC AND COLD AIR SHOULD BE SUFFICIENT FOR SEVERAL HOURS OF
ACCUMULATING SNOWFALL.

A BRIEF BREAK IN SNOW THURSDAY NIGHT WILL BE FOLLOWED BY A SECOND
ROUND OF SNOW FOR THE NORTHERN ZONES BEGINNING LATE THURSDAY
NIGHT...AND POSSIBLY CONTINUING THROUGH FRIDAY NIGHT. DEEP LAYER AND
RATHER MOIST WARM ADVECTION WILL DEVELOP ACROSS THE NORTHERN THIRD
OF THE STATE THURSDAY NIGHT. FAIRLY STRONG THERMALLY DRIVEN LIFT
SHOULD GENERATE ANOTHER ROUND OF WIDESPREAD SNOW...WITH OROGRAPHIC
ENHANCEMENT COMING IS PLAY AS THE MEAN FLOW REMAINS OUT OF THE
WEST-NORTHWEST.

THE NEXT...AND LIKELY MOST POTENT SYSTEM...WILL MOVE INTO THE
GREAT BASIN THIS WEEKEND. VERY COLD AIR WILL ACCOMPANY THIS
SYSTEM...LEADING TO STRONG DEEP-LAYER COLD ADVECTION TO WORK WITH
SOLID DYNAMIC LIFT AND DEEP-LAYER OVER THE REGION. THIS STORM WILL
LIKELY BE ANOTHER WIDESPREAD EVENT...WITH THE MOUNTAINS AND
WESTERN VALLEYS TAKING THE BRUNT OF THE NEW SNOW. THE SITUATION
ALSO WOULD BE FAVORABLE FOR A RATHER LONG OROGRAPHIC SNOW EVENT
FOR THE WASATCH RANGE...POSSIBLY EXTENDING THROUGH SUNDAY.

NO UPDATES PLANNED THIS EVENING.

&&

.AVIATION...THE SLC TERMINAL WILL SEE VFR CONDITIONS THROUGH THE
EVENING. LIGHT NORTHWEST WINDS ARE EXPECTED TO SHIFT TO THE
SOUTHEAST BY 05Z.

&&
