FORECAST ANALYSIS AND DISCUSSION
A STRONG STATIONARY RIDGE ALOFT IS KEEPING THINGS HOT, DRY AND
WINDY ACROSS NORTHERN ALASKA. THERE ISN'T MUCH CHANGE TO THE
ONGOING FORECAST IN THE SHORT TERM. EXPECT ISOLATED THUNDERSTORMS
IN THE SEWARD PENINSULA AND NW ARCTIC BOROUGH THIS
AFTERNOON/EVENING. THUNDERSTORMS WILL INCREASE IN COVERAGE ON
SATURDAY, INCLUDING THE ALASKA RANGE, WESTERN INTERIOR AND WESTERN
NORTH SLOPE. ON SUNDAY, EXPECT A MORE TYPICAL SUMMER DAY WITH
THUNDERSTORMS ISOLATED ACROSS MOST OF THE TERRAIN IN THE INTERIOR
AND BROOKS RANGE. THE EXTENDED FORECAST LOOKS TO CHANGE UP QUITE A
BIT.
FIRE WEATHER
A RIDGE OF HIGH PRESSURE PERSISTS ALOFT THROUGH
SATURDAY, THEN BEGINS TO WEAKEN AND BREAK DOWN SUNDAY. RED FLAG
WARNINGS FOR HOT, DRY, AND WINDY CONDITIONS ARE IN EFFECT ACROSS A
LARGE PORTION OF THE CENTRAL AND EASTERN INTERIOR BOTH THURSDAY AND
FRIDAY. WIND CONCERNS INCREASE LATE FRIDAY EVENING AS HIGH PRESSURE
AT THE SURFACE BUILDS OVER THE YUKON TERRITORY AND A THERMAL TROUGH
SHIFTS SOUTHWEST ALONG THE NORTH SLOPES OF THE ALASKA RANGE. THIS
WILL BRING GUSTY NORTHEAST WINDS FROM THE NENANA HILLS EAST TO THE
CANADIAN BORDER. WINDS WILL PERSIST THROUGH THE NIGHT FRIDAY NIGHT
OVER RIDGETOPS WITH POOR RELATIVE HUMIDITY RECOVERY EXPECTED.
SATURDAY WILL BE THE HOTTEST DAY WITH PERSISTENT NORTHEAST WINDS,
INCLUDING THE POSSIBILITY OF NEEDING ADDITIONAL RED FLAG WARNINGS
FOR THE NORTHWEST INTERIOR. THE RIDGE BEGINS TO WEAKEN SUNDAY,
BRINGING COOLER CONDITIONS AND A SHIFT TO MOSTLY SOUTHWEST WINDS
ACROSS ALL AREAS. CONDITIONS LOOK TO BE COOLER WITH HIGHER RH AND
MORE SHOWERS AND THUNDERSTORMS MOVING INTO NEXT WEEK, THOUGH
CONSECUTIVE DAYS OF WETTING RAINS IN THE SAME SPOT ARE NOT EXPECTED.
HYDROLOGY
NO CONCERNS AT THIS TIME.
EXTENDED FORECAST DAYS 4-7
A MUCH COOLER AND WETTER PATTERN IS LOOKING LIKELY. RAIN IS ALSO
LOOKING MORE LIKELY, ESPECIALLY IN THE CENTRAL AND EASTERN
INTERIOR MONDAY THROUGH WEDNESDAY NEXT WEEK WITH ISOLATED TO
SCATTERED SHOWERS OVER THE WEST COAST AND WESTERN INTERIOR.
TEMPERATURES LOOK TO DROP INTO THE 50S AND 60S IN THE INTERIOR
WITH SOME 40S AND EVEN 30S ON THE NORTH SLOPE. THERE HAVE BEEN
SOME HINTS AT SNOW, OR MIXED RAIN AND SNOW IN THE HIGHER PEAKS OF
THE BROOKS RANGE AS WELL, THOUGH WE WILL SEE HOW IT PLAYS OUT.
COASTAL HAZARD POTENTIAL DAYS 3 AND 4...NONE
