AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
401 PM MDT SAT MAR 21 2009

.SYNOPSIS...A WARM SOUTHWEST FLOW OVER THE AREA WILL GIVE WAY TO
A COLD PACIFIC STORM SYSTEM SUNDAY. A COLD NORTHWEST FLOW IN THE
WAKE OF THIS SYSTEM WILL PERSIST THROUGH MONDAY.

&&

.DISCUSSION...SOUTHWEST FLOW OVER THE FORECAST AREA CONTINUES TO
INCREASE AS A STRONG UPPER TROUGH APPROACHES THE CALIFORNIA COAST.
WIND GUSTS ARE APPROACHING ADVISORY CRITERIA OVER THE WEST DESERTS
AND THESE SHOULD ONLY STRENGTHEN THROUGH THE AFTERNOON AND
EVENING. CUMULUS CLOUDS ARE DEVELOPING OVER THE MOUNTAINS OF
NORTHERN UTAH...BUT SO FAR NO LIGHTNING STRIKES HAVE BEEN
OBSERVED. TEMPERATURES REMAIN QUITE WARM...AND MAXES ARE EXPECTED
TO RUN AROUND 15F ABOVE SEASONAL NORMALS.

THE SYSTEM IS STILL ON TRACK TO MOVE ONSHORE BEGINNING THIS
EVENING...BRINGING A COLD FRONT INTO FAR NORTHWESTERN UTAH
OVERNIGHT. WITH THE COLD AIR LAGGING BEHIND...THIS FRONT SHOULD
STALL DURING THE MORNING HOURS BEFORE IT MAKES IT THROUGH THE
WASATCH FRONT. THE UPPER LEVEL SUPPORT IS EXPECTED TO ARRIVE BY
TOMORROW AFTERNOON...PUSHING THE FRONT QUICKLY THROUGH THE STATE
BY EARLY MONDAY MORNING. THE 500 MB COLD POOL LOOKS TO STAY OVER
THE AREA THROUGH MONDAY MORNING...AND SHOWERS COULD LINGER OVER
THE MOUNTAINS THROUGH MONDAY AFTERNOON.

THE HEAVIEST PRECIP WILL BE SUNDAY AFTERNOON AND EVENING ALONG THE
FRONT...BUT WITH THE COLD AIR LAGGING BEHIND IT MAY NOT BE COLD
ENOUGH FOR SNOW IN THE VALLEYS UNTIL EARLY MONDAY MORNING.
HOWEVER...WITH TEMPERATURES AS WARM AS THEY HAVE BEEN...IT MAY BE
EVEN LONGER BEFORE THE GROUND IS COLD ENOUGH TO ALLOW VALLEY
ACCUMULATION. SOLID ADVISORY AMOUNTS SEEM TO BE A GOOD BET FOR AT
LEAST THE NORTHERN MOUNTAINS BUT AS THE SNOW IS NOT EXPECTED TO
BEGIN UNTIL THE SECOND PERIOD...WILL HOLD OFF ON ANY HEADLINES FOR
NOW.

MODELS INDICATE THAT THE PATTERN REMAINS PROGRESSIVE THROUGH THE
WEEK...WITH THE NEXT TROUGH DIVING IN TUESDAY THROUGH THURSDAY. GFS
INDICATES A MUCH STRONGER SYSTEM THAN THE EC WITH A WELL DEFINED
COLD FRONT. IN THE EC...THE SYSTEM IS WARMER AND NOT AS MOIST.
RAISED POPS SOME...BUT THERE STILL REMAINS QUITE A BIT OF
UNCERTAINTY.

&&

.AVIATION...GUSTY SOUTH WINDS ARE EXPECTED TO CONTINUE AT KSLC
THROUGH THIS AFTERNOON BEFORE GRADUALLY DECREASING THIS EVENING. A
40 PERCENT CHANCE EXISTS THAT A DRY COLD FRONT WILL PUSH THROUGH THE
TERMINAL BETWEEN 07-10Z TONIGHT...BRIEFLY SWITCHING WINDS TO THE
NORTHWEST AND LOWERING CEILINGS BELOW 7000FT AGL FOR NORTHERN
APPROACHES. IF THIS PANS OUT...CEILINGS ABOVE THE TERMINAL AND SOUTH
SHOULD REMAIN AT OR ABOVE 7000FT AGL AS THE FRONT IS EXPECTED TO
STALL OUT AND EVENTUALLY RETREAT AGAIN TO THE NORTHWEST. REGARDLESS
OF THE INITIAL FRONTAL SURGE...GUSTY SOUTH WINDS ARE EXPECTED TO
RAMP UP AGAIN AFTER 14Z SUNDAY MORNING AS THIS OCCURS. MVFR RAIN AND
POSSIBLY A RAIN SNOW MIX IS EXPECTED...BUT SHOULD HOLD OFF UNTIL THE
LATE AFTERNOON AND EVENING HOURS SUNDAY.
