Temperatures to drop overnight in Anchorage

By  | 

ANCHORAGE (KTUU) - While under mostly cloudy skies Wednesday in Anchorage we will see a high near 17 degrees.

A few light flurries Wednesday morning as our latest storm slowly moves off and dissipates. Cold Arctic air pretty soon will start moving down out of N.E. Russia to south of the Alaska Range while associated storm energy pushes eastward with this air flow and storm features Wednesday and Thursday.

As some of this storm energy moves toward us we could see some snow showers get triggered. But with the Arctic air settling southward anticipate increasing winds out of the Interior that usher in a drier air mass. Later in the forecast period a few snow showers could linger over portions of the Copper River Basin and along the coast from Prince William Sound eastward.

For the extended period, storms will persist over the Gulf of Alaska and south of the Aleutians with strong high pressure over the eastern Bering Sea while a cold air mass sits over the Alaskan Mainland. This cold air will keep temperatures around 20 degrees below average through the weekend.

This setup will favor the cold air moving down from the north and gusty mountain gap winds through coastal locations (in Southcentral) as well as precipitation mainly along the coastal regions of the Gulf. Storms that move out of the Pacific could bring Gale Force Winds (39-54 mph) to the western Aleutians at the end of the weekend.

Mostly cloudy skies in Anchorage on Wednesday with a high of 17 degrees. Mostly cloudy Wednesday evening but becoming partly cloudy as we drop down to 6 degrees.

Mostly sunny skies in Anchorage on Thursday with a high of 14 degrees. Partly cloudy skies Thursday night with a low of -4 degrees.

Looking ahead, Friday we will be under partly cloudy skies with a high of just 3 degrees but we drop down to 10 below on Friday night.
