Arctic air arrives tonight

RALEIGH, N.C. (WTVD) -- Conditions look to dry out this evening as much drier and colder air enters the region from the Ohio Valley. Low temperatures tonight will reach down into the middle 20s with partly cloudy skies. Through Thursday, temperatures will be 15-20 degrees below the historical average as Arctic air stays in place for the work week.

The next best chance of precipitation after this afternoon will be Tuesday night and Thursday evening with two separate pieces of energy passing through the Carolinas. Tuesday would most likely come in the form of snow, as Thursday would pose a risk for ice and mixed precipitation.

With the passing disturbance on Tuesday, the best dynamic support and influx of moisture is in the south and eastern portions of the viewing area. Confidence is highest in this region to see snow accumulations from 1-2 inches.

We continue to monitor the potential system bringing a chance of ice and wintery mix to the region on Thursday evening. There continues to be a model discrepancy on the extent of the mixed coverage across the Carolinas. The best chances once again look to be in the eastern parts of the viewing area where there is more available moisture later this week.

Have a good evening!
