The storm I talked about yesterday has pulled up east of Kodiak Island this morning deepening rapidly in the 970s. This low is throwing snow northward and will envelope the southern Kenai Peninsula in the next couple hours. Again cold air remains entrenched, and the warm air from the low is getting forced to move above the cold air. As the air is forced up it condenses into clouds and we get what is called overrunning snow, because the warm air overruns the cold air at the surface. A snow advisory has been issued for Kachemak Bay, specifically the Homer Bluff(my house again:). 3-8 inches expected today, but a lot depends on the track of the low, which is unusually uncertain this morning. The models are jumping all over the place with the track of this thing, and any minor change could shift the axis of heaviest snow and the snow amounts themselves dramatically. Bottom line though a lot of areas will get more Christmas snow with this system as it drifts northeast through Prince William Sound this evening. Tomorrow for Christmas Day we have an interesting setup of a trough moving through with strong cold advection from the west, which could set up some more snow for the western Kenai Peninsula. Again this is our lake-effect deal, and it can be very potent under right conditions. Merry Christmas Eve!
We shall see what happens!

INCLUDING THE CITIES OF...KENAI...SOLDOTNA...HOMER...

AROUND SELDOVIA AND ON THE HOMER BLUFF. NORTHEAST WINDS OF 15 TO
30 MPH ARE EXPECTED TO ACCOMPANY THE SNOW...POSSIBLY LEADING TO
