Valid 12Z Tue Jun 18 2024 - 12Z Sat Jun 22 2024

...Overview, Guidance Evaluation, & Preferences...
Ridging aloft manages to maintain itself across interior AK as a
cold low swipes northwest AK before retrograding.  The main storm
track remains south of AK, although a cyclone nears the AK
Panhandle towards the end of next week.  The guidance showed good
agreement.  The pressures, winds, and QPF were a blend of the 12z
deterministic guidance with increasing amounts of the 00z ECMWF
and 12z NAEFS means with time.  The remainder of the grids heavily
relied upon the 19z NBM.


...Weather/Hazards Highlights...
Winds to 30 knots/35 mph at times across the Aleutians, AK
Peninsula, the North Slope, and the west coast.  Precipitation
chances/amounts are highest near topography, and should be
convective in nature.  Precipitation amounts are expected to be
modest.  High temperatures are forecast to range from the upper
30Fs in the North Slope, 40Fs in the Aleutians, the 50Fs along the
south-central AK coast, 60Fs in the AK Panhandle, and the
70Fs/near 80F at times across the interior.  Low temperatures are
expected to dip below freezing across the North Slope and the
higher terrain of south-central and southeast AK.
