AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SALT LAKE CITY UT
325 PM MST THU FEB 17 2011

.SYNOPSIS...SOUTHERLY FLOW WILL REMAIN OVER THE AREA FOR THE NEXT
FEW DAYS. THE NEXT PACIFIC STORM SYSTEM WILL STRENGTHEN ALONG THE
CALIFORNIA COAST THE NEXT COUPLE OF DAYS...THEN EJECT EAST
NORTHEAST THROUGH THE GREAT BASIN LATE IN THE WEEKEND.

&&

.DISCUSSION...THE FORECAST AREA HAS RETURNED TO A SOUTHERLY FLOW
ALOFT IN THE WAKE OF THE COLD FRONT THAT MOVED THROUGH YESTERDAY.
THAT FRONT REMAINS STALLED OVER CENTRAL UTAH BUT HAS WEAKENED
CONSIDERABLY. LINGERING SHOWER ACTIVITY APPEARS TO BE MINIMAL...SO
HAVE GONE AHEAD AND CANCELED ANY REMAINING WINTER WEATHER
HIGHLIGHTS. ALSO LOWERED POPS SIGNIFICANTLY FOR THIS EVENING TO
ACCOUNT FOR THIS TREND.

THE TROUGH CURRENTLY OVER THE PACIFIC NORTHWEST COAST IS EXPECTED
TO DIVE SOUTH TO THE CALIFORNIA COAST TOMORROW THROUGH EARLY
SATURDAY...COMBINING WITH A SECOND WAVE MOVING ONSHORE ON
SATURDAY. MODELS CONTINUE TO AGREE THAT THIS BROAD TROUGH WILL
TRACK ACROSS NORTHERN ARIZONA/SOUTHERN UTAH SATURDAY AND
SUNDAY...BRINGING WIDESPREAD PRECIP TO MUCH OF THE STATE. LARGEST
ACCUMULATIONS SHOULD BE OVER THE SOUTH...COINCIDENT WITH THE BEST
FORCING. HOWEVER...COLD POOL INSTABILITY WILL ALLOW FOR A LOT OF
COVERAGE OF PRECIP ACROSS THE NORTH AS WELL. WITH THE GOOD
AGREEMENT AND RUN-TO-RUN CONSISTENCY...CONFIDENCE IS HIGH THAT
SOME AREAS WILL SEE SIGNIFICANT PRECIP WITH THIS SLOW MOVING
SYSTEM. HOWEVER...SOME UNCERTAINTY REMAINS WITH RESPECT TO THE
EXTENT OF THE IMPACT. THEREFORE...HAVE HELD OFF ON ISSUING A WATCH
AT THIS TIME.

MODELS BOTH SHOW BRIEF RIDGING DEVELOPING ON MONDAY BEHIND THE
TROUGH AND AN UNSETTLED PATTERN CONTINUING WELL INTO NEXT WEEK.
12Z RUNS ARE SHOWING A BIT MORE AGREEMENT THAN MODEL RUNS
YESTERDAY...AS BOTH THE EC AND GFS INDICATE A PACIFIC NORTHWEST
TROUGH DIGGING SOUTH APPROXIMATELY MIDWEEK. HOWEVER...THE EC KEEPS
THIS SYSTEM FARTHER WEST THAN THE GFS...SO THE GFS WOULD BRING
MORE SIGNIFICANT PRECIP AND COLDER TEMPERATURES THAN THE GFS
SOLUTION. BOTH DROP A SECONDARY TROUGH DOWN BEHIND THIS TROUGH FOR
FRIDAY...BRINGING ADDITIONAL PRECIP AND COLD AIR...THOUGH
TEMPERATURES IN THE EC SOLUTION ARE MUCH COLDER THAN THE GFS.

&&

.AVIATION...SOUTHERLY WINDS WILL CONTINUE THROUGH THE OVERNIGHT
HOURS AT THE SLC TERMINAL. LOW CEILINGS DID NOT MATERIALIZE THIS
AFTERNOON...AND EXPECT THAT CIGS WILL REMAIN ABOVE 7000 FEET
OVERNIGHT. HOWEVER...THERE IS STILL A 25 PERCENT CHANCE THAT CIGS
BETWEEN 6000 AND 7000 FEET WILL DEVELOP AT THE TERMINAL BEFORE 02Z.

&&
