Just when you thought it was safe to put your parka in the closet, it returns: THE POLAR VORTEX.

Yes, as the Capital Weather Gangs reports, things are going to get pretty cold starting next Tuesday through the end of the month. Here’s the forecast from the National Weather Service:

MONDAY NIGHT…MOSTLY CLOUDY. LOWS IN THE UPPER 20S.

TUESDAY…PARTLY SUNNY. HIGHS IN THE LOWER 30S.

TUESDAY NIGHT…MOSTLY CLOUDY. LOWS IN THE LOWER 20S.

WEDNESDAY…MOSTLY SUNNY. HIGHS IN THE UPPER 20S.

WEDNESDAY NIGHT…PARTLY CLOUDY. LOWS AROUND 20.

THURSDAY…PARTLY SUNNY. HIGHS IN THE UPPER 20S.

And it may be even colder than predicted. (Maybe even 20 to 30 degrees below average in much of the U.S.) But hey we could get snow! From CWG:

Systems will be diving southward from Canada which will probably offer us clipper type lows making any storms more likely to produce light to moderate snowfall than heavy. Could we get more than 4 inches from a storm? Yes, but like always, any such storm is a long shot.

Prepare.
