FORECAST ANALYSIS AND DISCUSSION
AN AMPLIFIED PATTERN PERSISTS WITH A STRONG, ANOMALOUS 586
DECAMETER RIDGE OFF THE WEST COAST OF THE LOWER 48. THIS RIDGE IS
PROVIDING SOUTHERLY FLOW OVER MAINLAND ALASKA AND ALLOWING A
SERIES OF LOWS AND SHORTWAVES TO MOVE FROM THE PACIFIC TO NORTHERN
ALASKA. THE MOST ROBUST OF THESE IS A PHASED 500 DECAMETER LOW
OVER THE SOUTHERN ALEUTIANS WITH AN ATMOSPHERIC RIVER ORIGINATING
IN HAWAII. THIS LOW ROTATES A FRONT INTO SW ALASKA TONIGHT
BRINGING HEAVY SNOW, WARM TEMPERATURE AND GUSTY WINDS. AS THE
FRONT PROGRESSES NORTHWARD, WE ARE EXPECTING VERY STRONG WINDS TO
PERSIST IN THE ALASKA RANGE PASSES, AND INCREASING WINDS OVER MOST
OF THE INTERIOR AND COAST THROUGH FRIDAY. THE STRONGEST WINDS
WILL LIKELY BE IN THE NORTHERN AK RANGE PASSES WITH GUSTS TO 80
MPH LIKELY ON FRIDAY. IN THE INTERIOR, MOST SPOTS WILL SEE NOTABLE
WIND GUSTS (20 TO 40 MPH) BUT IN THE TERRAIN ABOVE 1000FT, THERE
CAN BE GUSTS AS HIGH AS 60 MPH. SPECIFICALLY IN ALONG THE STEESE
AND DALTON HIGHWAY SUMMITS. FALLING SNOW ACCOMPANIED WITH THESE
WINDS LIKELY RESULT IN BLIZZARD CONDITIONS AT TIMES.
IN AND AROUND FAIRBANKS, THE WIND WILL BE LIGHTER OVERALL (20 TO
40 MPH) BUT THERE IS STILL A CHANCE FOR BLOWING AND DRIFTING SNOW.
THERE IS CURRENTLY AN IMMENSE AMOUNT OF SNOW ON MOST OF THE TREES
AND ANY WIND GUST OVER 25 MPH WILL LIKELY BLOW A LOT OF THIS SNOW
AROUND. AS THE WIND ARRIVES, TEMPERATURES WILL SIGNIFICANTLY
INCREASE (UPPER 20S TO LOW 40S AROUND THE INTERIOR) AS THERE WILL
BE A TREMENDOUS AMOUNT OF DOWNSLOPE FLOW FROM FRIDAY MORNING INTO
THE AFTERNOON. THIS IS THE TIMEFRAME WHEN FREEZING DRIZZLE OR
LIGHT FREEZING RAIN IS POSSIBLE. IN FNSB, MOST OF THE ICE CHANCES
WILL BE LIGHT (TRACE TO 0.03") BUT THAT IS STILL SIGNIFICANT AND
CAN RESULT IN TRECHEROUS DRIVING/TRAVEL CONDITIONS. HIGHER
AMOUNTS UP TO 0.10" ARE POSSIBLE IN THE ALASKA RANGE PASSES,
MOSTLY NORTH OF DENALI NAT'L PARK AND TRIMS CAMP. OUT WEST AND
ESPECIALLY SOUTHWEST, UP TO 0.10" OF ICE IS EXPECTED FROM GALENA
SOUTHWARD. FROM GALENA TO THE WHITE MOUNTAINS NORTHWARD, ALL OF
THE PRECIPIATION WILL BE SNOW, HEAVY AT TIMES ON FRIDAY.
THE WEATHER LOOKS TO QUIET DOWN GRADUALLY ON SATURDAY AND SUNDAY
WITH ONLY LIGHT PERIODS OF SNOW OR FREEZING DRIZZLE, ESPECIALLY IN
WESTERN ALASKA. THIS IS BEING FORCED BY A SHORTWAVE TROUGH RIDING
UP AND OVER THE RIDGE. THE MODELS MAY BE UNDERDOING THE AMOUNT OF
PRECIPITATION WITH IT, BUT IT CURRENTLY DOESN'T LOOK TOO IMPACTFUL
SINCE IT IS A MUCH WEAKER FRONT. THIS WILL BE MONITORED FOR MINOR
IMPACTS IN WESTERN ALASKA THOUGH.
EXTENDED FORECAST DAYS 4-7
DURING THE BEGINNING OF THE EXTENDED (MONDAY), A RIDGE OF HIGH
PRESSURE MOVES FROM THE ALASKA PANHANDLE TOWARDS MAINLAND ALASKA,
LIKELY BRINGING WARMER AIR AND DRIER CONDITIONS INTO NORTHERN
ALASKA. AS THE RIDGE CONTINUES TO MOVE WESTWARD, THE CENTER MAY
SET UP OVER THE WEST COAST BY WEDNESDAY, KEEPING THE AREA DRY, BUT
POTENTIALLY BRINGING COLDER AIR TO THE EASTERN NORTH SLOPE AND
INTERIOR TOWARDS THE END OF THE WEEK.
COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
