...THE INTERIOR ALASKA COLD SPELL CONTINUES...BUT A GRADUAL END IS
IN SIGHT...

A WEATHER FRONT FROM THE PACIFIC MOVED OVER THE SOUTHEASTERN
INTERIOR ON SATURDAY MORNING...AND BY LATE AFTERNOON IT MOVED OUT
OF ALASKA AND INTO WESTERN CANADA. THE INFLUX OF CLOUDS AND SOME
WARMER AIR ALOFT BROUGHT TEMPERATURES UPWARD IN MUCH OF THE
EASTERN INTERIOR FRIDAY NIGHT AND SATURDAY.

BY SATURDAY EVENING...CLEARING SKIES AND COLDER TEMPERATURES WERE
DEVELOPING IN THE EASTERN INTERIOR...AND IT REMAINED COLD IN THE
WEST. EVENING TEMPERATURES WERE MOSTLY IN A RANGE OF 20 BELOW TO
40 BELOW...WITH SOME 50 BELOW READINGS IN THE CENTRAL INTERIOR

THE DURATION AND THE DEPTH OF THE PRESENT INTERIOR COLD SPELL HAVE
NOT BEEN GREAT COMPARED TO PAST JANUARY COLD SNAPS. USING COMMONLY
USED TEMPERATURES TO MARK THE BEGINNING OF A COLD SPELL...THIS ONE
HAS RUN FOR ABOUT 10 DAYS. RECORD BREAKING INTERIOR COLD SNAPS IN
JANUARY CAN RUN AS LONG AS 3 1/2 WEEKS AND COME WITH TEMPERATURES
COLDER THAN 40 BELOW ZERO.

ALL OF THIS WILL FADE INTO THE PAST EARLY IN THE NEXT FEW DAYS. A
STRONG NORTH PACIFIC STORM IS HEADING NORTHWARD THROUGH THE GULF
OF ALASKA...AND IS DUE TO BRING CLOUDY SKIES AND A SIGNIFICANT
RISE IN TEMPERATURES STARTING SUNDAY AFTERNOON. THIS TREND WILL
SPREAD NORTHWARD OVER THE ALASKA INTERIOR THROUGH THE REST OF THE
WEEK.

TEMPERATURES SHOULD GO ABOVE ZERO IN MUCH OF THE ALASKA RANGE ON
SUNDAY...AND THEN THE SOUTHERN INTERIOR ON MONDAY AND TUESDAY.
MUCH OF THE NORTHERN INTERIOR IS EXPECTED TO SEE TEMPERATURES
RISE ABOVE ZERO BY THE END OF THE WEEK.

SOUTHERN INTERIOR TEMPERATURES ARE NOT EXPECTED TO REACH THE TEENS
ABOVE AT MID WEEK...BUT NOT MUCH ABOVE THAT BY WEEKS END.
TEMPERATURES ARE NOT EXPECTED TO GET CLOSE TO FREEZING.

WHILE ALASKAN WINTER COLD SPELLS HAVE AN UPPER LIMIT OF
DURATION...PERIODS OF ABOVE NORMAL TEMPERATURES CAN GO LONGER.
THIS MAY WELL BE THE CASE THIS COMING WEEK AND BEYOND.
