Forecast: Cloudy with temps in the mid 50s, scattered showers
ANCHORAGE, Alaska (KTUU) - Anchorage will be cloudy on Wednesday with light winds and a high of 56 degrees. Winds will blow from out of the southeast at 20-35 mph along Turnagain Arm as well as in higher elevations.
Again, Anchorage could see a pass bye or a scattered shower or two very similar to Tuesday. Wednesday night drops down to 46 degrees with light winds. Winds will blow from out of the east at 20-35 mph along Turnagain Arm as well as in higher elevations. It will be cloudy on Thursday with a high of 55 degrees and 10 mph winds. Rain chances will be in the 60 percent range. Thursday night drops down to 44 degrees with 10 mph winds while under cloudy and potentially rainy skies.
Looking ahead, it will be cloudy as weather warms up to 56 degrees for a high on Friday while rain chances still loom at around 70%.
Airflow out of the south should keep Southcentral looking up at overcast skies through Friday with little fluctuations in our morning, noon and nighttime temperatures. This flow will keep light rain going on Wednesday over the Chugach and Talkeetna Mountains before more storms move closer on Thursday. More persistent rain is expected over the Prince William Sound region
A low-pressure storm is moving out of the north Pacific and is expected to move over the Alaska Peninsula Wednesday night. The storm should be centered over southwest Alaska by Thursday. As these storms move into the mountains, clashing with low and high pressure in the northeast Gulf, strong winds will move through the major mountain passes.
Winds will strengthen on Thursday afternoon as the storm moves closer and over the upper Anchorage Hillside, Turnagain Arm and the Copper River Valley. The other weather impact from these storms will be widespread rain showers. Moisture stemming from the tropics will help push the storms north and up Cook Inlet, bringing persistent rain to the western Kenai Peninsula and Prince William Sound region. Up to 4 inches of rain may fall near Seward by Friday morning, with places like Whittier and Valdez receiving between 2.5 and 3 inches. The Anchorage bowl and Matanuska-Susitna valley are expected to stay dry at times while sitting behind mountain protection, but more than likely will see sporadic light rain showers through Friday with totals measuring near or less than 0.25 inches of rainfall by Friday morning.
For the extended forecast, Friday through Tuesday has cooler air stretched across western Alaska from the Arctic Coast southward to the Alaska Peninsula. A low-pressure storm tracking and moving north into the southern Gulf of Alaska will keep a cloudy, cooler and showery weather pattern over southern mainland Alaska for most of the weekend. On Saturday night, a large storm system will move into the western Bering Sea and to the south of The Alaska Peninsula by Tuesday. For the first half of next week, the strongest winds and heaviest rains from these storms will remain over coastal areas in the Bering Sea and the Gulf of Alaska.
