SPOT FORECAST FOR CHOSEN FROZEN (SCHOOL GROUP WINTER CAMP)...NATIONAL PARK SERVICE
NATIONAL WEATHER SERVICE ANCHORAGE AK
426 AM AKDT MON MAR 23 2026
FORECAST IS BASED ON FORECAST START TIME OF 0900 AKDT ON MARCH 23.
DISCUSSION
THE FORECAST AREA WILL BE BETWEEN HIGH PRESSURE AND AN ARCTIC
AIRMASS OVER THE YUKON TERRITORY AND LOW PRESSURE IN THE GULF OF
ALASKA. THIS WILL CREATE WINDS THROUGH THE GAPS AND PASSES OF THE
NABESNA MOUNTAINS AND THE WRANGLES, FUNNELING FROM EAST TO WEST.
WHILE WINDS WILL BE FAIRLY CALM TODAY, A SERIES OF UPPER LEVEL
DISTURBANCES FROM THE YUKON TERRITORY WILL MOVE THROUGH BRINGING
COLDER AIR AND GUSTIER WINDS. THIS PATTERN WILL PERSIST THROUGH AT
LEAST MID-WEEK.
A NOTE ON THIS FORECAST: THERE ARE NO WEATHER OBSERVATIONS IN
THIS AREA THAT WE HAVE ACCESS TO, SO LOCAL KNOWLEDGE ON WIND
PATTERNS MAY BE HELPFUL AS OUR OBSERVATIONAL NETWORK IN THIS AREA
IS SPARSE. THIS FORECAST REPRESENTS OUR BEST ESTIMATES FOR
TEMPERATURES AND WINDS. HIGHER OR LOWER WIND SPEEDS WILL GREATLY
IMPACT HOW COLD WIND CHILLS GET THROUGH THIS AREA. IF THE
CAMPGROUND IS IN A SHELTERED AREA FROM THE ALASKA RANGE NORTHEAST
WINDS, THEN WIND CHILLS WILL BE CLOSER TO THE FORECASTED AMBIENT
TEMPERATURES.
