National Weather Service talks clouds and cold snaps
Fairbanks has yet to see negative 40. The forecast earlier this week looked like it might get that cold but that has since changed.
"We are getting clouds that are streaming up from the Gulf of Alaska, so we are actually getting cloud cover that is keeping us warm," said Ed Plumb, the Warning Coordination Meteorologist with the National Weather Service.
Plumb said that there is a large cold air mass over Alaska and just west of Fairbanks there are temperatures of 40 and 50 below zero. The clouds that are bringing flurries in Fairbanks act as a blanket preventing heat from radiating into the atmosphere, Plumb said.
Looking forward, Plumb said the clouds will be moving east towards the Yukon Territory and Friday night could see temperatures of 40 below or colder. However, he said that another weather system will be moving in bringing snow and warmer temperatures on Saturday.
