Discussion

After a temporary “warm-up” on Sunday following the weekend snowfall, more Arctic air is pouring into the Mid-Atlantic region today and the new work week will get off to a much colder start compared to the end of the weekend. Temperatures today will drop through the 20's and an increasing wind will generate much lower wind chill values. Temperatures tonight will once again flirt drop to the single digits in much of the I-95 corridor and, unfortunately, that may not be the last time this week as very cold conditions are likely again late in the week after the arrival of another Arctic blast.

Looking back to the significant weekend snowfall in the I-95 corridor, what was quite amazing is that it took place with a steady, strong southerly wind. In normal winters, this type of synoptic weather pattern would have produced little in the way of accumulating snow in the I-95 corridor; especially, in late February, but given the extreme cold heading into the weekend, even a southerly wind couldn’t stop several inches of snow accumulation in the DC-to-NYC corridor.
