Temps stay below average for a couple of days

ANCHORAGE (KTUU) - Anchorage will warm up to 63 degrees on Friday with mostly cloudy skies.

The combination of the warm air mass over Interior Alaska and the high pressure over the Gulf of Alaska is producing the flow out of the south up Cook Inlet. This flow from the ocean out of the south is expected to persist the next several days. This will result in a significant cooling trend across the Southcentral region along with much higher minimum relative humidity.

The influx of cool, moist air into the Copper River Basin Thursday night and Friday morning will result in high temperatures decreasing by around 10 to 20 degrees Thursday through Friday compared to the last week.

Mostly cloudy in Anchorage on Friday with some areas of smoke, and early possible drizzle while we warm up to 63 degrees. Friday night we drop down to 56 degrees while under mostly cloudy skies with areas of smoke.

Mostly cloudy on Saturday with some areas of smoke while we see a high of 66 degrees. Friday night we drop down to 55 degrees while under mostly cloudy skies with some areas of smoke.

Looking ahead, Anchorage will be partly sunny early on Sunday with a high of 66 degrees with some areas of smoke.

Fire Weather for Southcentral: Instability remains high across the Copper River Basin Friday as well as along the Talkeetna and Chugach Mountains. Weak waves of storm energy will continue to track from the Northwest to the Southeast, north of the Old Denali Highway and will help to kick off more evening showers sparked by daytime heating from the sun with heightened lightning activity.

Saturday, thunderstorm activity will decrease as the warm air mass lifts to the north and weak high pressure ridging moves overhead.

Swan Lake Fire: Isolated thunderstorms over the Kenai Mountains can't be ruled out later this evening and overnight. Air steering flow that remained weak will begin to increase out of the southwest today. Any storms that form are expected to remain over the mountains.
