ANCHORAGE, Alaska (KTUU) — Arctic air moves south across much of mainland Alaska starting Sunday night. Cold temperatures return with lows between -20° to -40° in the Interior and dropping below zero in Southcentral.
Anchorage will see the change starting Monday night when lows will drop to near zero. The Matanuska-Susitna Valleys will see temperatures below zero overnight Monday. The cold won't be as dramatic as Southcentral saw in January and won't last for long. Lows will warm back up to the double digits by Friday night.
Northwest and Interior Alaska will also see the change in the weather starting Monday night. The low in Fairbanks Sunday night is expect to be near -8°. By Monday night, it will drop to near -30°. Cold temperatures are expected through most of the week in the Interior.
Heavy rain is moving into Southeast Alaska Sunday night and sticking around through Monday. Snow levels are expected to rise. As that snow melts, some rivers could rise and some ice cover may start to break. The rain won't last long, moving out of the Panhandle by Monday night, but another system following a similar path will move in on Wednesday, with models showing a third round of precipitation moving in on Friday.
