Ending The Cold Snap

Today likely marks the last day we'll be below average in temperatures for a couple of days. November's chilly start has been fueled by the cold trough that established itself in the wake of Sandy, having been reinforced by a disturbance that crossed late last week.

Temperatures have been below average for eleven straight days through yesterday.  For those keeping track at home, that's the longest stretch of consistent, persistent below average temperatures (not including days that were average) since March 23-April 3, 2011.  Yeah, it's been a while.

In fact, November 2012 is 7.5 degrees below average over the first nine days of the month.  Sunday through Tuesday will shave off a chunk of this cold anomaly, and the relatively benign week of weather that's to come after Tuesday's front should ease the negative departures further.  We won't be above average in a matter of days but the weather pattern will be much closer to average -- highs in the 50's, lows around 40.  Maybe a nudge or two below average but nothing like the last week plus.  In essence, a return to normalcy in our weather and for those who are still without power, a much-needed break in active weather and a lengthy stretch of "typical" November weather.  Not really shorts weather but benign weather...we'll take what we can get.

Prior to the March/April 2011 cool snap, the prior lengthy cold snap was February 6-18, 2010.  During that timeframe the region picked up 38.7 inches of snow after being popped by two major snowstorms (the bulk of the February 5/6 snowstorm and the second storm just four days later).  Such lengthy cool snaps have been relatively few in number the last couple of years.
