North Slope Blizzard

Here is the 10am AST Wednesday Northern Alaska Weather Depiction chart from the Alaska Aviation Weather Unit. Note the 30 to 40 knot sustained winds on the North Slope from Prudhoe Bay westward . Unusually for the North Slope, there is a lot of new snow falling in the strong warm advection over the top of the ridge, though the 40-1 raito snow used at Barrow at 18z is unrealistic.
