SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
100 PM AKDT MON APR 18 2011

.MODEL DISCUSSION...MODELS IN GOOD AGREEMENT ON PRIMARY WEATHER
FEATURES. HIGH PRESSURE FROM THE NORTHERN BERING ACROSS TO THE
SOUTHEASTERN GULF WITH A LOW SOUTH OF THE EASTERN ALEUTIANS AND
ANOTHER LOW IN THE CANADIAN ARCTIC.  THIS PATTERN PERSISTS THROUGH
MOST OF THE WEEK WITH A SECOND LOW NORTH PACIFIC LOW MOVING SOUTH OF
THE EASTERN ALEUTIANS WED AFTERNOON.  MODELS ALSO HINTING AT THE
DEVELOPMENT OF A WEAK AREA OF LOWER PRESSURE OVER THE TALKEETNA MTNS
WED IN RESPONSE TO A UPPER LEVEL TROUGH MOVING SOUTH FROM THE ARCTIC
COAST.

.ANALYSIS AND UPPER LEVELS...ONLY ACTIVE STORM IS IN THE CENTRAL AND
EASTERN ALEUTIANS WITH FRONT MOVING OVER SOUTHERN AK PEN THIS
AFTERNOON. HIGH PRESSURE OVER THE GULF AND NORTHERN BERING WILL KEEP
THIS SYSTEM CONFINED TO THE ALEUTIANS.

.SHORT TERM FORECAST...GENERALLY CLEAR OVER MOST LAND ZONES THROUGH
WED. CLOUD COVER WITH SOME SHOWERS POSSIBLE WED AFTERNOON NORTH OF
60N IN RESPONSE TO AFOREMENTIONED AREA OF LOWER PRESSURE THAT
DEVELOPS OVER SOUTHCENTRAL.SOME LOCAL AREAS OF COASTAL FOG IN THE
WEST.
BERING REGION...CONTINUED CLOUDY WITH RAIN AND SHOWERS OVER MOST OF
ALEUTIANS AND SOUTHERN THIRD OF AK PEN. ALTHOUGH SOUTHEAST WIND
SPEEDS DIMINISHING THIS EVENING IN THE EASTERN AL AND SOUTHERN AK
PEN...THEY WILL PERSIST BEFORE INCREASING A SECOND TIME WED EVENING.

.LONG TERM FORECAST...MODELS INDICATING THAT SECOND NORTH PACIFIC
SYSTEM SOUTH OF EASTERN ALEUTIANS MID WEEK WILL PRODUCE A FRONT THAT
MOVES INTO THE WESTERN GULF ON FRI. ALTHOUGH THERE IS CONSIDERABLE
UNCERTAINTY THERE IS POTENTIAL FOR CLOUD COVERAGE FOR MUCH OF
SOUTHCENTRAL AND BRISTOL BAY BY FRI MORNING WITH RAIN ALONG THE COAST
AS A RESULT OF MOIST SOUTHERLY FLOW.
