Well advertised pattern change still forecast to occur midweek
Thursday, November 28, 2013
Some very light snow is a possibility during the day Sunday, but amounts will be minimal.
Attention turns to the pattern change around midweek that was forecast as early as a week ago. A storm currently moving across Alaska will rapidly intensify in the Gulf of Alaska the weekend. Some energy splits from this storm by Wednesday and drags cold air across the northern third of the west. The rest of the storm drops south along the west coast and turns the flow over our area to the southwest. Good snow by Tuesday night or Wednesday morning should occur along the frontal boundary in our proximity.
Snow should be relatively steady until intensifying later in the work week as a cold wave from the polar regions kicks the storm over California to the west and over our area. I would expect significant accumulations from Wednesday through Friday before very cold and dryer mid-winter like air will moves over our area by Friday and especially Saturday.
Strong inversion are likely to develop and persist, keepiing mountain valleys in the deep freeze even as the upper elevations begin to moderate by the end of the weekend.
