- Chance for snow showers increase over the Interior Monday and Tuesday as some moisture makes it way into the Interior.
Accumulations around 1 to 3 inches possible over the E Interior.

North Slope and Brooks Range...

As well as warnings for the Nulato Hills for 6 to 12 inches of snow. Winter Weather Advisories still in effect for snow and blowing snow through tonight.

- Strong cold front will bring gales into Norton Sound and the YK Delta from the west, Sunday afternoon into Monday. While ice is in place, projected water levels of 1 to 2 feet above the normal high tideline may push pieces of sea ice onto the shore as well as push water through open leads, causing localized near shore water over ice.

Analysis and Forecast Confidence...
Strong Chinook flow continues over the Interior. Gusty south winds in the 70 to 80 mph range for Sunday. High Wind Warnings are in place for Sunday. Record high temperatures are also possible with the strong warm downsloping. Continued warm on Monday, then turning colder. Upper level flow turns more southwestly on Monday and Tuesday and the upper level low over the Seward Penn will track Northeast over the Brooks Range Tuesday and Wed. Snow could develop over the Interior as some moisture pushes across the area from the southwest. Colder air will filter back into the Interior through the week as ridging builds over the Interior.

Extended Forecast Days 4-7...
A chance for snow will occur over the SE Interior with a system moving from the Gulf into the SE Interior and E Alaska Range. Cooler temps and troughing with weak high pressure will develop later on Thursday with a chance for stormy weather to return to SW AK by Friday. Chinook flow could return to the Interior with warmer temps and windy conditions over the Alaska Range for next weekend.
