Discussion

Arctic air plunged into the Mid-Atlantic region late yesterday and temperatures today will be confined to well below normal levels for this time of year. After noticeable modification in temperatures on Wednesday, another Arctic cold front will arrive late Wednesday night/early Thursday and it is likely to be accompanied by some snow shower activity. Brutal cold Arctic air will follow that system for Thursday night and Friday along with bone-chilling winds.

Looking ahead, after a milder day on Saturday, signs point to another possible snow and/or rain event in the DC metro region in the Sunday/Monday time frame of next week. Elsewhere, yesterday's storm produced the 5th largest snowfall ever in Chicago, the 3rd largest in Detroit, and let's just say Boston is off the charts. Another foot of snow in the Boston area on Monday pushed some accumulation totals to nearly 50 inches in less than a week (throw in a Super Bowl championship and it makes for an interesting week).
