Meteorological Winter 2009-2010

There were a lot of close calls. There were a lot of blown forecasts. There were 3 separate northeast snowstorms/blizzards. All interior Connecticut has to show for it is a lackluster winter with below normal snowfall. Along the shoreline, however, it’s a somewhat different story with enough “glancing blows” that have delivered above normal snowfall.

Here’s how meteorological winter (December, January, and February) shaped up for Windsor Locks (BDL).

  • Temperature – 29.5º (+1.1º)
  • Snowfall – 30.5″ (-6.2″)
  • Precipitation – 12.1″ (+1.81″)
  • Heating Degree Days – 3169 (-127)

For Bridgeport (BDR)…

  • Temperature – 31.7º (-0.5º)
  • Snowfall – 38.0″ (+18.2″)
  • Precipitation – 13.3″ (+3.13″)
  • Heating Degree Days – 2981 (-13)

The one thing that has really been remarkable this winter is the major -NAO/-AO regime which has displaced the polar vortex south and resulted in an incredible amount of high latitude blocking. That has essentially driven the storm track too far south and delivered an historic winter to Philadelphia, Washington, D.C., and Baltimore.

What looks good on paper (-AO/-NAO) turned out to be a nightmare for forecasters and winter lovers that watched blizzards miss by mere miles.

A truly bizarre winter. Hello spring (and what the hell, maybe one March snowstorm).
