The temperature last night dipped below freezing just long enough to give us an inch and a half of wet snow. Sadly this snow is going to melt(again) with another storm system bringing warm air into the region early next week. A strong low and associated occluded front in the western Bering Sea is slowly weakening and drifting east. A triple-point low formed south of the Aleutians east of the parent low last night, and will rotate northwest over the next couple days, bringing light rain to the Pribilof Islands and SW mainland.
A new low is forming on the cold front south of the triple-point system. This new low is positioned under a very strong jet, and will strengthen rapidly as it moves northeast today and tomorrow. By Monday the GFS has it east of Kodiak with a pressure in the 960s. This low has another load of tropical air with it, and precipitation will be all rain along the coast under 5000 feet. More wind is likely with this system, but nowhere near as bad as the last storm.
We shall see what happens!
A triangle of lows approaches Alaska. The southernmost low on the map is the new one forming on the cold front. The one directly north of that is the triple-point low, and the low west of that is the parent low that started the whole thing. The Alaska mainland is in the top right corner.
