As if it wasn’t cold enough, this low pressure area, as it moves into the open waters of the Atlantic early Wednesday morning, will induce a southward push of brutally cold temperatures into the region. The cold will be further exacerbated by increasing winds across the region beginning tonight. Wind chill temperatures will likely be well below zero.

The jet stream, or upper level wind pattern, continues to exhibit a deep trough (or dip) over the northeastern United States, while as a large ridge remains in place over the western states. Bitter cold air looks to remain locked in place over the Capital Region for the coming work week, with only slight temperature moderations through the weekend. In addition, several weak disturbances look to graze the region through the coming week, helping to keep the frigidly cold air in place.

Temperatures are forecast to average below normal, while precipitation amounts average near to slightly below normal as well.
