Area forecast discussion, Jan 28, 3:10 PM AKST, 12 hours 18 minutes before

NORTHERN ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FAIRBANKS AK
310 PM AKST SAT JAN 28 2012

.DISCUSSION...
MODELS IN DECENT AGREEMENT THROUGH AT LEAST 48 HOURS WITH JUST THE
UPPER LEVEL LOW POSITION DIFFERING BY LATE MON NIGHT. THE UKMET IS
VERY FAR OFF IN TERMS OF 500H LEVEL WHERE THE NAM...ECMWF AND GFS
ARE IN DECENT AGREEMENT.

BY THE FIRST PART OF NEXT WEEK...AROUND 00Z WED IS WHEN THE MODELS
ARE STARTING TO DIVERGE GREATLY. THE ECMWF DECIDES TO PUSH THE
UPPER LEVEL LOW BACK SOUTHEASTWARD TOWARD MAINLAND ALASKA AND
DRIVE A TROUGH DEEP INTO THE GULF OF ALASKA. HOWEVER THE NEW GFS
18Z RUN DOES COME BACK MORE IN LINE WITH THAT OF THE ECMWF. A
BRIEF WARM-UP IN THE BEGINNING OF THE WEEK BEFORE BUT IT APPEARS
NOW THAT THE DEEP UPPER LEVEL TROUGH OVER NORTHWEST ALASKA WILL
BE ABLE TO CHOKE BACK THE BUILDING RIDGE FROM THE SOUTHEAST.

A SERIES OF LOW PRESSURE SYSTEMS WILL ENTER THE GULF OF ALASKA AND
PROVIDE RETURN FLOW OVER THE EASTERN PORTION OF THE STATE WHICH
WOULD BE A GOOD SET UP FOR OVERRUNNING PRECIPITATION TOWARDS THE
END OF THE WEEK.

CURRENTLY...MID RANGE MODELS DO NOT INDICATE ANY LONG TERM
MODERATION IN TEMPERATURES OVER NORTHERN ALASKA THROUGH THE NEXT
180 HOURS.

WINDS ALONG THE WESTERN ARCTIC COAST WILL CONTINUE TO PRODUCE LOW
WIND CHILLS THROUGH SUNDAY.
