Here are the snow maps for this weekend's snowfall. This is a case of cold sloshing down and waves of low pressure running along the fronts. Not until we can get the PNA to go positive can we get a storm to wind up despite the negative NAO. So with the PNA not positive, we will tend to see mean trough position in the Rockies and an up-and-down temperature pattern for the eastern part of the country.
A cold and wintry weather pattern setting up prior to the Holidays.
Cold air spreads out across much of the country and leads to a battle ground of snow and ice in the East.
Lake snows will be heavy in some of the traditional NW flow locations.
Storm will bring a lot of wild weather the next 24 hours.
A storm will bring wintry weather and severe weather as well. Not the best prior to Thanksgiving.
