Greensboro, NC -- A cold front will sweep through the Triad Monday evening and usher in the leading edge of the coldest blast of air the contiguous United States has seen this winter.
This cold front will not bring much more than a few clouds as it moves through, but once it moves to the east the winds will increase and the temperatures will steadily plummet.
Temperatures Monday night will bottom out in the middle 20s, but a westerly wind around 15 mph will make it feel more like the middle teens.
The entering Arctic air will be incredibly dry which will allow for ample sunshine Tuesday, but it won't be enough to overcome the advancing chill. Temperatures Tuesday afternoon will struggle to climb above freezing with wind chills only rising into the low 20s. Winds through the day on Tuesday will be out of the northwest around 15 mph with gusts near 20 mph.
The coldest of the Arctic air won't arrive until Tuesday night when low temperatures will drop into the mid-upper teens with even colder temperatures possible in rural areas. While the winds will begin to relax somewhat Tuesday night, even a 5-10 mph wind will make temperatures feel like they are in the single digits.
The last time the Triad experienced low temperatures in the teens was on February 13, 2012 when the low temperature was 19 degrees. So far this winter the coldest temperature recorded at the Piedmont Triad International Airport was 21 degrees which was on November 25th.
There will be slightly warmer temperatures through the second half of the week, but highs will remain 5-10 degrees below normal until next week. The normal high temperature for this time of the year is 48 degrees and the normal low temperature is 30 degrees.
