ANCHORAGE (KTUU) - While under cloudy rainy skies Thursday Anchorage warms to near 48 degrees.
Rain and mountain snow will persist into today (Thursday) as the first low-pressure system moves onshore and a secondary area of low pressure develops and lifts northeast toward the Copper River Delta. The heaviest of the precipitation will fall over Prince William Sound, Copper River Delta, and Chugach Mountains, ahead of the center of circulation. Rain over the Copper River Basin Thursday (today) is then expected to switch over to snow Thursday night and Friday morning as the system tracks to the Alaska Peninsula and pulls colder air south. Accumulations of 2 to 5" are expected across the Copper River Basin Thursday night. There is still some uncertainty concerning how quickly the colder air arrives and just how much moisture moves over the Copper River Basin, and any change in these ingredients will impact snow totals. Therefore, this will continue to be monitored as the event draws closer.
For the Mat-Su Valleys, Anchorage Bowl, and Kenai Peninsula, the rain and higher elevation snow will taper off to scattered rain/snow showers through the day Thursday as colder and drier air arrives on the backside on the low. Although snow levels will drop late Thursday, most of the moisture will have exited the region by then. This will keep any additional snow accumulations rather light (less than an inch) and confined to the higher terrain (Turnagain Pass and the Upper Hillside or Anchorage included). Gusty winds out of the north will also develop late Thursday into Friday, especially along the coast, in the wake of the departing low.
Cloudy and rainy on Thursday with a high of 48 degrees with a 60 percent chance for rain showers. Thursday night we drop down to 37 degrees with a 60 percent chance for rain showers in the evening with the possibility of turning into the snow as temps cool overnight. Light winds becoming northwest 10-15 and gusting to 30 mph after Midnight.
Mostly cloudy skies in Anchorage Friday with winds out of the northwest at 15 mph and gusting to 30 mph. Mostly cloudy Friday night with winds out of the north at 15 mph as temperatures drop down to near 24 degrees.
Looking ahead, Anchorage will be sunny on Saturday with a high of 40 degrees.
