ANCHORAGE (KTUU) - While under mostly cloudy to cloudy skies Thursday Anchorage warms to near 60 degrees.
As storms move into the area a brief period of light rain is possible across the Anchorage Bowl and Mat-Su Valleys, but a quick transition to a downsloping wind as the main front advances will limit precipitation amounts in these areas. The focus then shifts to the main weather event: an approaching frontal system attached to a Bering low. Rain and strong winds out of the south will develop over Kodiak Island tonight as a strong storm energy in the upper atmosphere lifts into the western Gulf in association with the front.
The influx of tropical moisture from the remnants of Typhoon Faxai will lead to heavy rain from Kodiak to Prince William Sound as this front progresses north and east Thursday and Thursday night. In addition to the rain, strong winds will develop ahead of and along the front, with gales over the coastal waters and gusty, gap winds out of the southeast across the mainland.
The strongest winds are expected through terrain gaps of the Kenai and Chugach Mountains, as well as the Copper River Valley. Downsloping with limited precipitation along the lee (non-wind side) of the mountains is expected due to the cross-barrier flow. However, given the strong forcing with this system and copious tropical moisture, there may be enough energy to overcome the effects of downsloping at times, leading to a bit more rain along the non-wind side of the mountains than is usual with these events.
Mostly cloudy to cloudy in Anchorage Thursday with winds out of the northeast at 15 mph. We could see rain at times while winds blow from 25-40 mph from the southeast along Turnagain Arm as well as in higher elevations. Temps will fall to 55 degrees overnight with a 90 percent chance of showers while winds blow from 20-35 mph from the southeast along Turnagain Arm as well as in higher elevations.
Cloudy on Friday with a high of 60 degrees and a 50 percent chance of rain showers. While under cloudy skies Friday night we drop down to 47 degrees.
Looking ahead, Anchorage will be partly sunny on Saturday with a high of 62 degrees.
Fire Weather: The focus of fire weather will be on the strong front on Thursday. This will bring gusty winds out of the east and southeast to the interior Kenai Peninsula as well as the Copper River Basin. The Kenai Peninsula is more likely to see periods of rain while the Copper River Basin remains mostly dry.
Our winds will be out of the northeast at 15 mph in Anchorage on Thursday but out of the southeast from 25-40 mph along Turnagain Arm and in higher elevations. A windy day as storms pass through the area.
