AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
500 AM AST FRI JAN 13 2006

.DISCUSSION...
AUGUSTINE VOLCANO IS ERUPTING THIS MORNING. NOT A WHOLE LOT OF
INFORMATION AVAILABLE AT THIS TIME...PLEASE SEE APPLICABLE
STATEMENTS...INCLUDING NPWAER AND MWSAFC.

A TYPICAL WINTER WEATHER PATTERN OVER ALASKA TODAY. DEEP LOW OVER THE
WESTERN ALEUTIANS BRINGING STORM AND GALE FORCE WINDS TO MOST OF THE
BERING SEA AND ALEUTIAN CHAIN. A SHORT WAVE RIDGE OVER THE PANHANDLE
SEPARATES THAT LOW FROM A WEAK LOW IN THE NORTHERN GULF. DECENTLY
COLD TEMPERATURES OVER THE MAINLAND UNDER A WEAK UPPER LEVEL LOW
UNDER FAIRLY CLEAR SKIES.

CONDITIONS WILL REMAIN FAIRLY DRY AND COLD OVER THE MAINLAND INTO
NEXT WEEK AS THE JET STREAM REMAINS WELL SOUTH OF THE AREA. IN FACT
THE STORM TRACK IS EXPECTED TO REMAIN NEAR 50 NORTH LATITUDE FOR THE
NEXT WEEK OR SO. THIS WILL HAVE STORMS CHUGGING ALONG AND BRINING
HIGH WINDS TO THE ALEUTIANS. THIS WILL ALSO KEEP PRECIPITATION WELL
TO THE SOUTH OF THE ALASKA MAINLAND FOR THE MOST PART...WITH ONLY
OCCASIONAL SHOTS OF MOISTURE AS THE STORMS PASS BY. HOWEVER...WITH
THE LOW OVER THE STATE AND WEAK CYCLONIC FLOW...SOME SNOW IS
POSSIBLE...AS WAS THE CASE IN MCGRATH YESTERDAY.
