Area forecast discussion, Apr 13, 1:45 PM AKDT, 2 hours 15 minutes before
SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
145 PM AKDT FRI APR 13 2012
.ANALYSIS AND UPPER LEVELS...
A VERY LARGE AREA OF CYCLONIC CIRCULATION TAKING SHAPE OVER THE NORTH
PACIFIC AND BERING SEA. UNDER THIS BROAD CIRCULATION ARE SEVERAL
SHORTWAVES EMBEDDED IN THE UPPER FLOW. THE JET THAT IS SUPPORTING
THIS DEVELOPMENT RESIDES WELL SOUTH OF OUR REGION ACROSS THE NORTH
PACIFIC NEAR THE 40N PARALLEL. OVER ALASKA...WEAK FLOW ALOFT IS
LEADING TO MOSTLY PLEASANT WEATHER WITH A FEW AREAS OF STRATUS AND
FOG OVER THE SOUTHWESTERN PORTION OF THE STATE.
.MODEL DISCUSSION...THE PREFERRED MODEL SOLUTION IS A BLEND OF THE
ECMWF AND THE NAM. THE GFS IS AN OUTLIER WITH RESPECT TO THE
SHORTWAVES EMBEDDED IN THE BROAD CYCLONIC CIRCULATION. THE 12Z GFS
WANTS TO RAPIDLY RESOLVE THE MULTIPLE WAVES INTO A SINGLE LOW WHILE
THE NAM AND ECMWF KEEP A MUCH MORE REALISTIC MULTI-CENTERED LOW
COMPLEX THROUGH THE WEEKEND. THIS NUDGE WILL RESULT IN SLIGHTLY
STRONGER WINDS ALONG THE ALASKA PENINSULA AND NEAR SHELIKOF STRAIT AS
ONE OF THE WAVES NEARS THE REGION LATE TONIGHT.
.SHORT TERM FORECAST...
SOUTHCENTRAL...SOME MID LEVEL INSTABILITY EVIDENT ON THE 12Z
ANCHORAGE SOUNDING RESULTED IN A FEW MORE CLOUDS THIS MORNING AND A
BIT OF VIRGA. THE ATMOSPHERE WAS QUITE DRY BELOW 5000 FEET SO NO SNOW
OR RAIN MADE IT TO THE SURFACE DESPITE THE RADAR LIGHTING UP EARLY
THIS MORNING.
THE CONVECTIVE PARAMETERS ARE STILL IMPRESSIVE...FOR THIS TIME OF
YEAR AT LEAST...SO A STRAY SHOWER IS NOT OUT OF THE QUESTION THIS
AFTERNOON. WILL LIKELY SEE MORE ACTIVITY ALONG THE MOUNTAINS OR THE
HIGHER ELEVATIONS WHERE THE MOISTURE IS A BIT MORE PLENTIFUL. THIS
ACTIVITY DIMINISHES OVER NIGHT AS HIGH PRESSURE BUILDS AHEAD OF THE
FRONTAL BOUNDARY ASSOCIATED WITH THE NORTH PACIFIC COMPLEX LOW.
UPPER LEVEL CLOUDS ARRIVE SATURDAY AFTERNOON OVER SOUTHCENTRAL WITH
RAIN AND SNOW CONFINED TO THE COASTAL AREAS THROUGH THE WEEKEND. ONLY
A SLIGHT CHANCE OF PRECIPITATION EXISTS FOR THE INTERIOR AREAS OF
SOUTHCENTRAL AS THE ENERGY REMAINS WELL SOUTH.
.SOUTHWEST...STRATUS AND FOG ACROSS SOUTHWEST ALASKA IS CURRENTLY
DISSIPATING EARLY THIS AFTERNOON LEAVING MOSTLY SUNNY SKIES AND ABOVE
AVERAGE TEMPERATURES. THE AXIS OF THE UPPER LEVEL RIDGE WILL SHIFT
SLIGHTLY INLAND OVERNIGHT. THIS WILL DISPLACE THE MOST LIKELY REGION
TO SEE FOG TOWARD THE MIDDLE AND UPPER KUSKOKWIM VALLEY. THE
APPROACHING LOW SOUTH OF THE ALASKA PENINSULA SHOULD TIGHTEN THE
GRADIENT ENOUGH OVER BRISTOL BAY TO MITIGATE THE CHANCES OF FOG
OVERNIGHT. MID AND UPPER LEVEL CLOUDS INCREASE SATURDAY MORNING
ALTHOUGH NO SIGNIFICANT PRECIPITATION IS ANTICIPATED THROUGH THE
WEEKEND.
.BERING SEA/ALEUTIANS...VERY BENIGN WEATHER OUT WEST WITH LIGHT
NORTHERLY FLOW PERSISTING. HIGH PRESSURE BUILDS OVER THE WESTERN
BERING THROUGH THE WEEKEND WITH STRATUS AND A FEW SHOWERS LINGERING
ALONG THE ALASKA PENINSULA.
THE ONE CHANGE TO THE PREVIOUS FORECAST WILL INCLUDE BUMPING UP THE
WINDS JUST SOUTH OF THE ALASKA PENINSULA TO STORM FORCE. THE MODELS
HAVE BEEN TRENDING THIS DIRECTION SEVERAL RUNS IN A ROW ADDING TO OUR
CONFIDENCE IN MINIMUM STORM FORCE WINDS ALONG THE FRONTAL BOUNDARY.
.AER/ALU...WATCH/WARNING SUMMARY
PUBLIC...NONE.
MARINE...STORM 150 155
GALE 120 130 132 138 170
FIRE WEATHER...NONE.
