A very cold upper level Arctic low dropping south over the
Western Interior will bring an anomalously cold airmass to the
area over the weekend. There will be clouds, periods of
precipitation and even snow above 2000 feet, but low-lying areas
that clear during the overnight and early morning hours will see
temperatures drop quickly into the low to mid 30s. West of
Fairbanks to near Tanana, frost is most likely on Saturday
morning. For Fairbanks and east to the Alcan Border, frost is
possible on Saturday morning, but more likely Monday morning. On
Sunday morning, widespread clouds should keep temperatures in the
upper 30s and 40s, but isolated areas that clear may still
develop frost. Frost is unlikely for all but the lowest lying
valleys and along rivers.
