NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
105 PM AKDT SAT AUG 4 2012

.DISCUSSION...
NEW MODEL RUNS FOR BOTH THE ECMWF AND THE GFS ARE MUCH MORE IN
LINE WITH EACH OTHER. BOTH MODELS KEEP DEVELOP A SURFACE LOW IN
THE THERMAL TROUGH OVER NORTHERN RUSSIA AND THEN MOVE IT EASTWARD
WHILE DEEPENING IT VERY SUBSTANTIALLY. THE LOW THEN BRINGS IN A
LARGE AMOUNT OF COLD AIR BEHIND IT AS THE LOW MOVES NORTHEAST.

EXTREME WARM ADVECTION OVER THE NORTHWEST ARCTIC COAST WILL BEGIN
TONIGHT AND CONTINUE THROUGH SUN BEFORE VERY STRONG COLD ADVECTION
POURS IN FROM THE NORTHWEST SUN NIGHT. AS THE COLD FRONT MOVES IN
ACROSS THE NORTHWEST ARCTIC COAST...IT WILL PUSH PRECIPITATION
ACROSS THE ARCTIC COAST THROUGH MON.

THE UPPER LEVEL RIDGE THAT IS PUSHING IN FROM FAR EASTERN RUSSIA
WILL GET SQUASHED OUT BY MON AFTERNOON ACROSS THE CENTRAL PORTION
OF THE STATE. AS THE COLD FRONT PUSHES ACROSS THE WESTERN INTERIOR
ON MON AND TUE...IT SLOWS DOWN BUT CONTINUE TO MOVE TO ABOUT THE
MIDDLE TANANA VALLEY BY WED.

THE WEST COAST WILL BE FAIRLY DRY FOR MUCH OF NEXT WEEK UNTIL THU
OR SO DUE TO THE UPPER LEVEL RIDGE EXTENDING OVER THE AREA. THE
NEXT UPPER LEVEL LONG WAVE TROUGH WILL MOVING IN ON THU WHICH WILL
RESUPPLY MOISTURE AGAIN TOT HE WEST COAST ZONES.

STRONG SOUTHWEST WINDS OVER PORTIONS OF THE NORTHWEST ARCTIC COAST
WILL DEVELOP THIS EVENING AND CONTINUE THROUGH SUN BEFORE TURNING
WESTERLY AND THEN SLIGHTLY NORTHWESTERLY THROUGH TUE. THIS WILL
HAVE THE POTENTIAL OF BRINGING IN ICE TO THE SHORE AROUND BARROW
DURING THIS TIME.
