models very similar through 60 hours. Very cold upper level trough
over central portion of the state will move eastward as it is
shoved by the high amplitude building ridge moving in from the
Upper low near east of Kodiak will move to about Juneau by late
Sun night while a resistant upper low continues to hold near
Denali park. An upper high will develop over northwestern Alaska
and continue to build through Tuesday.
Overrunning snowfall over eastern and central interior for today
is likely about over. A few areas of light snow showers will
continue to fall through tonight but not amount to much at all.
As a deep surface low in the Bering Sea weakens rapidly and moves
eastward, the occluded front will stretch out but and the gradient
will increase substantially over Saint Lawrence Island and the
Bering Strait by late tonight and early Sunday. The gradient will
spill northward to around Point Hope.
The precipitation shield will make it to Saint Lawrence Island but
not really further east than that. Significantly warmer air will
fill in behind the front.
Arctic coast will likely see clouds on the increase but the
stratus and fog not as likely. The remainder of the week should be
mostly preciptiation free and limited clouds.
Coastal hazard potential days 3 and 4...none.
