Forecast: Next bitter cold blast could arrive by Christmas

Mike Nelson forecasts arrival around Dec. 20th

DENVER - Looking ahead to Christmas week, 7NEWS Meteorologist Mike Nelson says he expects another bitter cold blast to hit Colorado.

Nelson says he expects it to arrive in Colorado around the 20th of December and stick around for several days. It could be a new "Polar Express" just in time for the holiday!

The attached photo shows a long-range computer model for the morning of December 24th. That big H just north of Colorado is a very strong and cold high pressure system.

The surface pressure indicated in milibars is 1046 - that is a really intense high and that means very cold, dense air!  It would be the equivalent of almost 31.00" on a home barometer - that is way around the top of the pressure dial!

If this forecast verifies, we would be getting another surge of bitter cold air swinging in here late next week.  Several inches of snow would fall in Denver by the 20th or 21st, with heavy snow in the mountains as well.

Temperatures would plummet well below zero for the days leading up to Christmas, so the snow would certainly stay on the ground.  Travel before the holidays would certainly be impacted by the bitter cold and the snow.

To the east, the cold wave would plunge the central and eastern United States into more snow, freezing rain and sub-freezing temperatures - especially by Christmas Eve and Christmas Day.  Heading that direction for the holidays may well be a challenge!
