AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
100 PM AST SUN FEB 18 2007
.DISCUSSION...
A 986 MB LOW SOUTH OF THE AKPENN IS HAVING LITTLE IMPACT...STRONG
WINDS ARE ALL TO THE SOUTH OF THE LOW...AND JUST SHOWERS ALONG THE
PACIFIC COAST. THE UPPER JET WILL DRIVE THIS LOW EASTWARD TONIGHT
ACROSS THE SOUTHERN GULF AND TO SOUTHEAST ALASKA BY TOMORROW.
MEANWHILE THE LOW OVER THE CENTRAL BERING CONTINUES TO SLOWLY WEAKEN.
THE REMAINS OF THE FRONT ARE LYING OVER SOUTHWEST ALASKA WITH
AREAS OF LOW CLOUDS...SNOW...AND FOG. ONSHORE FLOW OVERNIGHT WILL
MAINTAIN THESE CLOUDY AND FOGGY CONDITIONS WITH A FEW SNOW SHOWERS.
FLOW WILL THEN SHIFT TO THE NORTH MONDAY AND PRODUCE GRADUAL CLEARING
ACROSS SOUTHWEST ALASKA. A SHORT-WAVE ROTATING AROUND THE SOUTH SIDE
OF THE BERING SEA LOW IS GENERATING A CONCENTRATED AREA OF SNOW.
WINDS ARE INCREASING BEHIND THIS SHORT-WAVE OVER THE WESTERN TO
CENTRAL ALEUTIANS (TO AROUND 45 KTS) AS ANOTHER ROUND OF COLD
ADVECTION BEGINS. THESE STRONGER WINDS WILL SPREAD EASTWARD TONIGHT
AND MONDAY AND THEN PUSH SOUTHWARD INTO THE PACIFIC AS A RIDGE BUILDS
OVER THE WESTERN BERING SEA. THE NEXT WEST PACIFIC LOW WILL HELP
AMPLIFY THIS RIDGE MONDAY AND TUESDAY WHICH IN TURN WILL ALLOW A HIGH
AMPLITUDE TROUGH TO TAKE SHAPE FROM THE BEAUFORT SEA SOUTHWARD ACROSS
ALASKA AND THE GULF INTO THE EAST PACIFIC. A STORM FORCE FRONT WILL
AFFECT THE FAR WESTERN ALEUTIANS BEGINNING MONDAY NIGHT AND THEN
FALL APART AS IT TRIES TO PUSH EASTWARD INTO THE RIDGE.
THE LARGEST IMPACT OF THIS PATTERN CHANGE WILL BE ON MAINLAND ALASKA
WHICH WILL FALL BACK INTO A PERIOD OF HARSH WINTER CONDITIONS.
MULTIPLE SHORT-WAVES WILL DROP SOUTHWARD ACROSS THE STATE BEGINNING
MONDAY BRINGING DEEP ARCTIC AIR WITH THEM. MODELS HAVE BEEN
CONSISTENT IN INDICATING A 20 DEGREE DROP IN 850 TEMPS ACROSS
SOUTHCENTRAL ALASKA FROM THIS AFTERNOON THROUGH THE END OF THE WEEK
(DOWN TO AROUND -30 DEGREES CELSIUS). COLDER AIR WILL BEGIN TO FILTER
INTO THE REGION TONIGHT AND MONDAY. HOWEVER...BEGINNING MONDAY NIGHT
AND CONTINUING THROUGH TUESDAY STRONG COLD ADVECTION WILL OCCUR
ACROSS THE REGION. THE SURFACE PRESSURE GRADIENT WILL ALSO TIGHTEN
UP SIGNIFICANTLY AS THE LOW SOUTH OF THE AKPENN DEEPENS OVER THE GULF
TONIGHT AND MONDAY. COMBINATION OF COLD ADVECTION AND UPPER
SHORT-WAVES WILL LIKELY AID IN GENERATION OF ANOTHER LOW OVER THE
GULF BY TUESDAY...ALL MODELS INDICATE A WEAK LOW FORMING...BUT WOULD
NOT BE SURPRISED TO SEE THIS LOW DEEPEN BEYOND WHAT THE MODELS ARE
INDICATING. INITIALLY WINDS ALOFT ARE FAIRLY WEAK. THIS WILL CHANGE
TUESDAY NIGHT INTO WEDNESDAY AS THE BERING RIDGE SHIFTS A BIT
EASTWARD AND A JET FORMS ALONG WESTERN ALASKA AND SOUTHEASTWARD
ACROSS WESTERN PORTIONS OF SOUTHCENTRAL ALASKA...WHICH WILL HELP
PROLONG THE COLD AND WIND INTO NEXT WEEKEND.
IN DECIDING WHETHER TO ISSUE ANY WIND WATCHES/WARNIGNS/ADVISORIES WE
NEED TO BALANCE THE STRENGTH OF THE COLD ADVECTION AND THE SURFACE
PRESSURE GRADIENT WITH THE LACK OF UPPER SUPPORT. BECAUSE THE AIR IS
SO COLD AND THE ADVECTION IS SIGNIFICANT WILL GO AHEAD AND ISSUE HIGH
WIND WATCHES FOR VALDEZ TO THOMPSON PASS AND THE COPPER RIVER DELTA.
WITH COLD DENSE AIR PLUMMETING OFF THE MOUNTAINS AND BEING CHANNELED
THROUGH THE GAPS ITS RELATIVELY EASY TO REACH WARNING CRITERIA IN
THESE LOCATIONS. FOR OTHER AREAS SUCH AS BROAD PASS...THE MAT
VALLEY...AND SEWARD AND WHITTIER...WITHOUT UPPER SUPPORT THINK
STRONG WIND HEADLINE SHOULD SUFFICE WITH FORECAST WINDS AROUND
60 MPH. BECAUSE THE AIR IS SO COLD WILL ALSO ISSUE WIND CHILL
ADVISORIES FOR ZONE 131...141...AND 145...LOCATIONS THAT WILL SEE
A COMBINATION OF STRONG WINDS AND COLD TEMPS.
