AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
500 AM AST MON FEB 4 2008

.MODEL DISCUSSION...
MODELS IN REASONABLY GOOD AGREEMENT. ALL MODELS TOO QUICK TO DISSOLVE
SMALL LOW NEAR CAPE SUCKLING ALTHOUGH THEY DO KEEP A TROUGH OF LOW
PRESSURE ALONG THE GULF COAST. COLD OUTFLOW FROM THE INTERIOR IS
LIKELY TO HELP MAINTAIN THIS FEATURE THROUGH AT LEAST TUE MORNING.

.SURFACE FEATURES...
SMALL 1003 MB LOW NEAR CAPE SUCKLING REMAINS NEARLY STATIONARY FOR
THE TIME BEING.
A 987 MB LOW NEAR 60N 143W WILL DEEPEN TO 974 MB AS IT MOVES OVER THE
SOUTHERN SOUTHEAST PANHANDLE TUE MORNING...IT HEN WEAKENS AS ITS
MOVES INTO WESTERN CANADA TUESDAY NIGHT.
A NEARLY STATIONARY 985 MB LOW 150 NM SOUTHWEST OF SAINT GEORGE WILL
WEAKEN TO 997 MB BY MON AFTERNOON THEN DISSIPATE BY TUE MORNING.
A LARGE 962 MB LOW NEAR 41N 165E WILL BECOME A 977 MB LOW JUST SOUTH
OF THE CENTRAL ALEUTIANS NEAR 51N 171W TUE NIGHT.

.UPPER LEVELS...
UPPER LEVEL HIGH WILL REMAIN ANCHORED OVER THE CHUKOTSK PENINSULA
THROUGH AT LEAST THURSDAY.
UPPER LEVEL LONG WAVE TROUGH OVER MAINLAND ALASKA EXTENDS FROM FORT
YUKON TO ILIAMNA THIS MORNING. BY TUESDAY MORNING IT WILL HAVE
SHIFTED TO ALIGN ITSELF ALONG AN INUVIK TO YAKUTAT LINE.

.FIRST 36 HOURS...
THE PRESSURE GRADIENT ALONG THE GULF COAST WILL TIGHTEN AGAIN
TONIGHT. GOOD POTENTIAL FOR SERIOUS WIND CHILLS ACROSS MOST OF
SOUTHCENTRAL AND SOUTHWEST ALASKA TONIGHT. NORTH WINDS MAY EXCEED 75
MPH THROUGH THOMPSON PASS AND THE COPPER RIVER DELTA BEGINNING THIS
EVENING. BUT BEST POTENTIAL FOR HIGH WINDS WILL BE IMMEDIATELY
FOLLOWING THE PASSAGE OF THE UPPER LEVEL TROUGH LATE MONDAY NIGHT.
QUASI STATIONARY SYSTEM IN THE SOUTHERN BERING SEA CONTINUES TO
SPREAD BLIZ CONDS TO SAINT GEORGE AND OCCASIONALLY SAINT PAUL AS
WELL. EAST WINDS WILL WEAKEN ONLY SLIGHTLY TODAY. BUT PRECIPITATION
WILL TAPER OFF TODAY OVER THE PRIBILOFS SO VISIBILITIES SHOULD
IMPROVE AROUND MID AFTERNOON.
MAIN EFFECT OF 962 MB LOW MOVING TOWARD THE CENTRAL ALEUTIANS WILL BE
TO MAINTAIN THE EASTERLY 35 TO 50 KT FLOW ACROSS THE SOUTHERN BERING
SEA AND ALEUTIAN CHAIN THROUGH AT LEAST WEDNESDAY. BEST CHANCE OF
PRECIP WITH THIS SYSTEM WILL BE OVER THE CENTRAL AND EASTERN
ALEUTIANS AND WILL FALL ALMOST ENTIRELY AS SNOW.

.BEYOND 36 HOURS...
UPPER LEVEL STEERING FLOW VERY STABLE. PERSISTENCE WILL REIGN THROUGH
AT LEAST THE NEXT SIX DAYS.
COLD ARCTIC AIR WILL HOLD OVER MAINLAND ALASKA. THE PRESSURE GRADIENT
ALONG THE GULF COAST WILL ALTERNATELY STRENGTHEN AND WEAKEN CREATING
PERIODS OF NORTHERLY GAP WINDS.
A SERIES OF MODERATE TO STRONG STORMS WILL MOVE UP OUT OF THE NORTH
PACIFIC INTO THE BERING SEA. BUT WILL BE BLOCKED FROM ADVANCING
FURTHER BY THE UPPER LEVEL BLOCKING HIGH. WARM AIR ADVECTION
ASSOCIATED WITH THESE SYSTEMS WILL BE ONLY MINIMAL.
