.DISCUSSION...
ANALYSIS - A WEAK UPPER LOW IS OVER THE CENTRAL GULF THIS MORNING
OVER A 1003 MB SURFACE LOW BOTH OF WHICH ARE FILLING. AN UPPER TROUGH
EXTENDS SOUTHWEST TO ANOTHER LOW AROUND 45N 170W WITH A SURFACE LOW
COMPLEX THERE AROUND 1008 MB. A STRONG UPPER RIDGE IS ALONG 180 AND
IS DEFINITELY PROGRESSIVE.  A WEAK WARMFRONT IS MOVING ACROSS THE
CENTRAL BERING SEA THIS MORNING WITH A HIGH CENTER OF 1018 MB OVER
THE CENTRAL ALEUTIANS. THERE IS NOT MUCH OF A JET THIS MORNING WITH
ONLY AROUND 95 KT ALONG 50N SOUTH OF THE AKPENN. RADAR AND SATELLITE
PIX SHOWS LOTS OF MOISTURE OVER THE NORTH GULF ASSOCIATED WITH THE
LOW. THE 12Z KING SALMON RAOB IS UNSTABLE AND SOUTHWEST AK IS THE
TARGET FOR CONVECTION THIS AFTERNOON AND EVENING.

AER FORECASTS - BIG PATTERN CHANGE TAKING PLACE. DUE TO PROGRESSION
THE UPPER RIDGE WILL BUILD EASTWARD WITH THE AXIS AROUND 165W BY 18Z
FRI AS PER ALL THE MODELS. THIS KICKS OUT THE UPPER LOW CENTER TO THE
EASTERN GULF FOR DOWNWARD VERTICAL MOTION. THE RIDGE WILL END UP OVER
SOUTHCENTRAL BY 12Z SAT WITH VERY HIGH HEIGHTS OVER THE REGION BY SUN
EVENING. LOOK FOR DRYING...MUCH WARMER TEMPS...AND PEOPLE IN
ANCHORAGE WILL FINALLY GET TO CUT THEIR LAWNS.

ALU FORECASTS - IT LOOKS LIKELY THAT SOME MOISTURE WILL MAKE IN INTO
THE SW COAST BUT NOT BEFORE THE K-VALLEY AND NORTHERN 161 GET SOME
THUNDERSTORMS THIS AFTERNOON AND EVENING. AS THE UPPER RIDGE BUILDS
EASTWARD THE GFS DEVELOPS A 990 MB LOW NW OF SHEMYA BY 06Z FRI HENCE
THE GALES AND THE WIND ADVISORIES IN THE BERING. A FRONT DEVELOPS
WITH THIS SYSTEM BUT AS THE RIDGE BECOMES A BLOCK THE FRONT WILL
BEGINNING TO DISSIPATE IN THE CENTRAL BERING SEA SAT. LOOK FOR SOME
WEAK WAVES ON THE FRONT TO THE SOUTH ON SUN AS THE SYSTEM BECOME
COMPLETELY BLOCKED.
