SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
400 PM AKDT THU OCT 18 2012

.ANALYSIS AND UPPER LEVELS...THE UPPER LEVEL PATTERN IS BASICALLY THE
SAME TODAY AS YESTERDAY WITH LOW PRESSURE OVER THE NORTH GULF OF
ALASKA AND HIGH PRESSURE CENTERED OVER THE CENTRAL BERING SEA. THESE
FEATURES WILL BOTH MOVE EASTWARD THROUGH THE REST OF THE WEEK LEAVING
STRONG HIGH PRESSURE AND NORTHERLY FLOW OVER THE MAINLAND PART OF THE
STATE THROUGH THE WEEKEND.
THE SURFACE LOW THAT WAS IN THE NORTHERN GULF YESTERDAY MOVED
EASTWARD NEAR YAKUTAT WHILE A SECONDARY LOW DEVELOPED OVERNIGHT NEAR
MIDDLETON ISLAND. THIS IS KEEPING THE PRESSURE GRADIENT MORE RELAXED
OVER THE NORTH GULF COAST WITH A TIGHT GRADIENT TOWARD KODIAK ISLAND.
THE SURFACE HIGH IS CENTERED JUST EAST OF ADAK AND ENCOMPASSES A
LARGE PART OF THE BERING SEA. THE PRESSURE GRADIENT BETWEEN THE HIGH
AND LOW IS TIGHTEST FROM IN SOUTHWEST MAINLAND ALASKA AND ALONG THE
ALASKA PENINSULA.

.MODEL DISCUSSION...MODELS ARE STILL DOING WELL OVERALL. THEY REMAIN
VERY CONSISTENT THROUGH THE NEXT THREE DAYS FROM THE EASTERN BERING
SEA AND EASTWARD. WHERE THERE IS SOME DISAGREEMENT COMING INTO THE
PICTURE INS IN THE WESTERN TO CENTRAL BERING SEA SATURDAY AND SUNDAY.
THE GFS AND ECMWF ARE MORE CONSISTENT WITH THEIR MOVEMENT OF THE
FRONT WHILE THE NAM IS A BIT OF AN OUTLIER WITH THIS FEATURE. THIS
THEREFORE THE GFS/ECMWF IS THE PREFERRED SOLUTION IN THE BERING SEA
FOR THE WEEKEND.

.SHORT TERM FORECAST...RAIN AND SNOW SHOWERS AROUND THE LOW NEAR
MIDDLETON ISLAND WILL REMAIN MAINLY OFFSHORE OVER THE GULF OS ALASKA.
AN ISOLATED SNOW SHOWERS MAY REACH THE GULF COAST AND A WEAK SHORT
WAVE JUST NORTH OF THE ALASKA RANGE COULD BRING A SNOW SHOWER ALONG
THE RANGE IN THE FAR NORTHERN COPPER RIVER BASIN.
OTHER THAN THAT SOUTH CENTRAL ALASKA WILL BE PARTLY CLOUDY TO MOSTLY
CLEAR TONIGHT INTO THE WEEKEND AS WINDS BECOME THE MAIN WEATHER
FEATURE. NORTHERLY WINDS WILL INCREASE ALONG THE NORTH GULF COAST AND
NORTHEAST WINDS IN THE MATANUSKA VALLEY FRIDAY AS THE PRESSURE
GRADIENT TIGHTENS AND UPPER LEVEL FLOW INCREASES FROM THE NORTH.

SOUTHWEST ALASKA...NORTH TO NORTHWEST WINDS WILL PERSIST IN SOUTHWEST
MAINLAND ALASKA THROUGH THE NIGHT...THEN BEGIN TO DIMINISH FROM WEST
TO EAST AS THE RIDGE CENTER MOVES CLOSER TO THE AREA FRIDAY INTO
SATURDAY. WINDS ALONG THE ALASKA PENINSULA WILL REMAIN BRISK THROUGH
FRIDAY AND THEN DIMINISH IN THAT AREA AS WELL.

.LONG TERM FORECAST...A LARGE UPPER LEVEL BLOCKING HIGH WILL BUILD
AND AMPLIFY OVER THE BERING SEA AND MUCH OF MAINLAND ALASKA THROUGH
EARLY NEXT WEEK. THIS WILL KEEP PARTLY CLOUDY TO MOSTLY CLEAR SKIES
OVER MAINLAND ALASKA WITH NEAR NORMAL TO A LITTLE BELOW NORMAL
TEMPERATURES.

.AER/ALU...WATCH/WARNING SUMMARY
PUBLIC...NONE.
MARINE...GALE 130 176.
FIRE WEATHER...NONE.
