SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
415 PM AKDT WED MAR 11 2015

.ANALYSIS AND UPPER LEVELS...
FAIR SKIES CONTINUE ACROSS THE MAINLAND AS COLD AIR SPILLS
OFFSHORE. COLD AIR OVER THE MAINLAND COMBINED WITH SUPPORTING
NORTHERLY 850 MB WINDS AND LOW PRESSURE OVER THE GULF CONTINUED
BRISK AND GUSTY GAP AND OUTFLOW WINDS ACROSS THE NORTHERN AND
WESTERN GULF. THESE OUTFLOW CONDITIONS WERE EVIDENT WITH THE
PRESENCE OF CLOUD BANDS ON VISIBLE SAT IMAGERY. OPEN/CLOSED CELL
CU AND SNOW SHOWERS WERE OBSERVED  ACROSS THE BERING SEA AS COLD
NORTHERLY WINDS STREAMED OFF THE MAINLAND/ICE PAC. A FRONTAL
TROUGH WAS APPROACHING THE WESTERN ALEUTIANS.

&&

.MODEL DISCUSSION...
SHORT TERM MODEL SOLUTIONS ARE IN GOOD AGREEMENT IN THE GULF. THE
GEM REG/NAM MODEL WIND FIELDS INITIALIZED WELL ACROSS THE WESTERN
GULF COMPARED TO OBSERVATIONS AND SAR IMAGERY. OUT WEST...MODELS
SOLUTIONS HAVE A FAIRLY SIMILAR HANDLING OF THE FRONTAL STRUCTURE
AND SURFACE LOW...SIGNIFICANT DIFFERENCES HOWEVER DO CREEP IN
AFTER FRI AFTERNOON...ESPECIALLY WITH THE HANDLING OF THE LOW
MOVING SOUTH OF THE CHAIN.

&&

.SHORT TERM FORECAST SOUTHCENTRAL ALASKA (DAYS 1 AND 2)...
THE WEATHER REGIME WILL REMAIN THE SAME WITH CLEAR AND COLD
TEMPERATURES AND SUNNY SKIES DURING THE DAY THROUGH THURSDAY.
THERE IS A NORTH PACIFIC LOW TRACKING TO THE NORTHEAST GULF OF
ALASKA BY THURSDAY MORNING JUST SOUTHEAST OF YAKUTAT. THIS
SYNOPTIC FEATURE COMBINED WITH AN UPPER LEVEL TROUGH THAT WILL BE
DROPPING DOWN FROM THE NORTH INTO THE WESTERN GULF BY THURSDAY
WILL FURTHER STRENGTHEN THE PRESSURE GRADIENTS. THEREFORE THE GAP
WINDS WILL REMAIN GUSTY FROM THE BARREN ISLANDS INTO THE PRINCE
WILLIAM SOUND HEADING INTO THE WEEKEND. THE BARREN ISLAND WILL
SEE STORM FORCE WINDS BY LATE TONIGHT THROUGH TOMORROW AS THE
UPPER LEVEL TROUGH CONTINUES TO DROP DOWN INTO THE AREA. THE
COPPER RIVER BASIN WILL SEE AN INCREASE IN CLOUDS AS THE NORTH
PACIFIC LOW TRACKS TO THE NORTHEAST GULF. THIS WILL BRING A LARGE
SWATH OF MOISTURE AND SNOWFALL TO THE SOUTHEAST COPPER RIVER
BASIN BY FRIDAY.

&&

.SHORT TERM FORECAST SOUTHWEST ALASKA (DAYS 1 AND 2)...
GENERALLY COLD AND DRY CONDITIONS WILL DOMINATE THE SOUTHWEST
MAINLAND THROUGH FRIDAY AS COLD AIR CONTINUES TO FILTER INTO THE
REGION IN NORTHERLY FLOW ON THE BACK SIDE OF THE UPPER TROUGH
CENTERED OVER THE INTERIOR. THE MAIN FORECAST CHALLENGE IN THIS
TIME PERIOD WILL BE WIND CHILLS AS WINDS BEGIN TO INCREASE WITH
THE PASSAGE OF A WEAK UPPER LEVEL DISTURBANCE. HOWEVER THIS
FEATURE WILL ALSO SPREAD MID LEVEL CLOUDS OVER THE KUSKOKWIM
VALLEY AND DELTA TONIGHT KEEPING TEMPERATURES FROM PLUMMETING
LOWER AND THUS KEEPING WIND CHILL VALUES FROM REACHING ADVISORY
CRITERIA.

&&

.SHORT TERM FORECAST BERING SEA/ALEUTIANS (DAYS 1 AND 2)...
BROAD NORTHERLY FLOW OVER THE EASTERN BERING WILL KEEP SNOW
SHOWERS FOCUSED ALONG THE NORTH SIDE OF THE ALASKA PENINSULA AND
THE EASTERN ALEUTIANS THROUGH THURSDAY NIGHT. FURTHER WEST A GALE
FORCE FRONT WILL BRING A MIX OF SNOW AND RAIN TO THE WESTERN AND
CENTRAL ALEUTIANS THROUGH FRIDAY AS IT MOVES SLOWLY EAST AND THEN
STALLS OVER THE CENTRAL BERING.

&&

.LONG TERM FORECAST (DAYS 3 THROUGH 7)...
COLD CONDITIONS WILL PERSIST INTO THE WEEKEND FOR MAINLAND ALASKA
DUE TO THE TROUGH OVER THE EASTERN PART OF THE STATE. MEANWHILE A
LOW SOUTH OF THE ALEUTIANS WILL TRACK TO THE EAST AND PUSH A FRONT
INTO THE GULF COAST LATE THIS WEEKEND. THERE ARE DIFFERENCES
BETWEEN THE MODELS ON WHEN THIS FRONT WILL MAKE IT TO THE
SOUTHCENTRAL REGION BRINGING BACK WARMER CONDITIONS. THE EC AND
GEM ARE FASTER WITH A SATURDAY NIGHT ARRIVAL WHILE THE GFS IS
SLOWER AND BRINGS IT SUNDAY AFTERNOON. CURRENTLY THERE IS HIGHER
CONFIDENCE WITH THE EC AND GEM SOLUTIONS.
