The overall pattern first appears to be mild for much of the nation during the latter part of the month, unless the polar vortex comes into play.

"There are some indications that the polar vortex may weaken enough to allow a southward discharge of arctic air prior to the end of the month," according to AccuWeather Lead Long-Range Meteorologist Paul Pastelok.

"Even in cases when there is certainty about the weakening of the polar vortex, you never know for sure where the discharge of cold air will be directed, such as western versus eastern U.S.," Pastelok said.

If the polar vortex remains strong, then it will keep the arctic air locked up in the Arctic and more places in the lower 48 states may trend warmer rather than colder late in the month.

"We believe the eastern part of the U.S. will trend colder and stormier again toward the end of the month, but the question is how much," Pastelok said.
