NORTH ALASKA FORECAST DISCUSSION
230 PM ADT SUN JUL 3 2005

.DISCUSSION...THE ETA AND GFS FORECASTS ARE IN PRETTY GOOD
AGREEMENT TODAY...THOUGH THE ETA DEEPENS THE TROUGH ALOFT OVER
NORTHEAST ALASKA MORE THAN THE GFS BY TUESDAY MORNING. PREVIOUS
MODEL RUNS HAVE FORECAST THIS FEATURE TOO STRONGLY ON A
CONSISTENT BASIS SO THE GFS LOOKS BETTER IN THIS REGARD. IN ANY
CASE...THE WESTERLIES OVER THE SOUTH CHUKCHI SEAS ARE PICKING
UP.

THE MESO ETA MODEL HAS A SURFACE LOW NEAR BARROW AT 10 PM ADT
TUESDAY EVENING WITH CONSIDERABLY MORE DEFINITION THAT THE
OTHER MODELS AND IT MAY WELL BE CORRECT. THE MESO ETA SURFACE
WINDS TUEDSAY EVENING ALONG THE ARCTIC COAST FROM POINT HOPE TO
WAINWRIGHT ARE SOUTHWEST 25 TO 35 KNOTS. DUE TO THE LINGERING
ICE COVER IN THE CHUKCHI AND THE FAIRLY NARROW AREA OF OPEN WATER
FROM ICY CAPE TO NORTH OF BARROW (ONLY 20 TO 60 NAUTICAL MILES
WIDE) SURF DOES NOT YET LOOK LIKE IT WILL BE A PROBLEM. BUT
THIS WILL BE AN IMPORTANT CHANGE FROM THE UNEVENTFUL WEATHER
THAT HAS PREVAILED UP THERE FOR SOME TIME.

THE UNSTABLE AIR MASS OVER THE INTERIOR WILL PROBABLY BECOME A
LITTLE COOLER AND MORE STABLE OVER THE NEXT FEW DAYS AS WESTERLY
FLOW AT THE SURFACE AND ALOFT BRING IN MARITIME AND MODIFIED
MARITIME AIR. WESTERN ALASKA REMAINS UNCHARACTERISTICALLY DRY.
FOLLOWING THIS WESTERLY STABILIZATION...THE GFS AND ECMWF MIDDLE
RANGE FORECASTS SHOW THE RIDGE ALOFT OVER WEST CANADA REBUILDING
OVER THE ALASKA MAINLAND...SUGGESTING TO NO ONES SURPRISE THAT
SUMMER AINT OVER YET.

.HYDRO...QUIET. RAINS HAVE DIMINISHED. GLACIAL MELT HAS TANANA
RIVER ROLLING ALONG PRETTY FAST...BUT WITHIN ITS BANKS.
.FIRE WEATHER...SCATTERED SHOWERS/FEW THUNDERSHOWERS...MOSTLY
WET. NO STRONG WINDS.

.AFG WATCH/WARNING/ADVISORIES...
PUBLIC...NONE.
MARINE...SMALL CRAFT AREAS 210 AND 220.
