.DISCUSSION...Northwest flow will be in place across the region
behind a departing trough today. The flow will flatten some on
Monday and Tuesday as a strong low develops over the Gulf of
Alaska. This will open the door for periodic, light Snow Showers
on Monday. A strong disturbance will blast through the region on
Wednesday, bringing a round of Snow and Wind. Arctic air will
filter in behind the system, bringing the coldest air so far this
season to the region to close out the week.
