ANCHORAGE (KTUU) - Winter storm watches have been issued for the Anchorage Bowl, Matanuska Valley and Western Kenai Peninsula (excluding areas south of Anchor Point) Wednesday evening into early Thursday morning as a mixture of snow, freezing rain, and rain is expected.
On Thursday, that could turn into up to two inches of snow.
Our main focus is the low pressure system pushing north from the Gulf on Wednesday, bringing increased precipitation chances to Southcentral through Thursday.
Winds will continue out of the northeast due to the Arctic High Pressure over the Alaska Canada border as well as relatively cold surface conditions in the Anchorage Bowl, Matanuska Valley and Western Kenai Peninsula with temperatures in the upper 20s to low 30s.
Meanwhile, as the warm front pushes warmer air push towards the coast, freezing rain will be possible.
Warmer air sinking down the mountain sides could cause for warmer drier conditions thus keeping rain chances instead of snow for the Anchorage Bowl, Matanuska Valley and Western Kenai Peninsula. This will keep varying precipitation amounts.
While under mostly cloudy skies Wednesday Anchorage warms to near 35 degrees.
For the extended period, a low pressure system will be sitting over Bristol Bay and the Alaska Peninsula on Saturday with more storms tracking up into the Gulf of Alaska. This will bring rounds of high winds and heavy precipitation to coastal areas and the Gulf Coast/Kodiak Island.
Some precipitation could spread inland to Southcentral and Southwest Alaska, with rain or snow depending on location. Saturday night or Sunday and continuing into next week or longer we will see more storms move rather quickly through the Bering Sea and close to the Aleutian Island chain.
Bottom line: the extended forecast period will be characterized by an active storm pattern with widespread weather impacts likely across the entire region.
While under mostly cloudy skies in Anchorage Wednesday we warm up to 35 degrees as rain and freezing rain chances increase throughout the day. Wednesday night we drop down to 31 degrees with winds out of the northeast from 10-15 mph as storms deliver a 70 percent chance of freezing rain along with the possibility of 1" of snow after midnight.
Thursday we are looking at a 70% chance of rain and snow with snow accumulations up to 2" as temps warm up to 36 degrees while winds blow out of the northeast from 10-15 mph. Thursday night we will be mostly cloudy as we drop down to 27 degrees overnight while winds blow out of the northeast from 10-15 mph. Slight chances for snow and rain as well.
Looking ahead, Anchorage will be cloudy on Friday with a high of 32 degrees while winds blow out of the northeast from 10-15 mph.
