ANCHORAGE (KTUU) - While under cloudy skies Tuesday Anchorage warms to near 37 degrees.
Winds seem to be a little bit too strong for last night's fog in Palmer to last too long into Tuesday morning. Patchy fog is also possible on the Copper River Basin. High pressure over the Yukon Territory and a front over the Gulf of Alaska will lead to potentially gusty winds out of the northeast in terrain gaps across Southcentral through Tuesday morning.
The difference in the atmospheric pressure across the area should lessen as our latest storm tracks northward, at which time rain is expected to begin along Prince William Sound and the western Kenai Peninsula. As temperatures cool overnight ahead of the front, higher elevation snow is likely north of Valdez as well as the wind facing side of the Chugach Mountains.
Precipitation will continue to move north on Wednesday. Accumulating snow is likely along portions of the Denali and Richardson Highways in the Paxson area. Anchorage and the Mat-Su are expected to remain mostly dry given the surface airflow out of the east.
For the extended period, a weakening low-pressure system in the Bering Sea will keep conditions relatively warm and unstable from the Gulf over to Southwest Alaska and across much of the southern Bering. On Friday conditions look to improve slightly as a ridge of high pressure over the Interior initiates a clearing and drying offshore flow from the north/Interior across much of the southern mainland. This is expected to be short-lived, however, especially for Southcentral, as more storms lift north into the Gulf of Alaska beginning late Friday through Monday.
There will be early patchy freezing fog in Anchorage with a 40% chance of some early flurries, light drizzle or rain while under cloudy skies as we warm up to 37 degrees on Tuesday. Winds will be out of the north at 15 mph but out of the east from 25-40 mph along Turnagain Arm as well as in higher elevations.
Tuesday night we drop down to 34 degrees while under mostly cloudy skies with winds out of the north at 15 mph but out of the east from 35-50 mph along Turnagain Arm as well as in higher elevations
Mostly cloudy Wednesday as we warm up to 42 degrees with 15 mph winds out of the north but up to 50 mph along Turnagain Arm as well as in higher elevations. Wednesday night we will be mostly cloudy as we drop down to 34 degrees with 15 mph winds out of the north but up to 45 mph along Turnagain Arm as well as in higher elevations.
Looking ahead, Anchorage will be cloudy on Thursday with a high temperature of 43 degrees as well as winds out of the east from 10-20 mph along Turnagain Arm as well as in higher elevations.
