Winter '11 / '12 - Meteorological Winter - Month Three

CAR alone enjoyed a 'normal' snowfall this winter.  No other station came even close to normal.

March is the last month for the 'season-total' snowfall forecast contest.  Latest round of long range progs hold little hope for a late rally.



Climo columns are the summed monthly totals for DEC...JAN...and FEB.

Winter '11 / '12 - Snow Storm #2 - Call for Forecasts - Take Two

26-FEB-1969
Boston
Appears to be a sloppy Miller 'B' storm poised to rake much of New England come Wednesday followed by the remnants of the parent LOW on Thursday.  Moderate strength HIGH to the north expected to keep columns cold enough to support a contest-worthy storm.

Might as well fuggetabout the classic nor'easter this season.

The contest may be canceled prior to the deadline if NWP indicates a fizzling event.

Winter '11 / '12 - Meteorological Winter - Month Two

NWS finally got around to issuing their month-end climo bulletins for NEWxSFC forecast stations.

Here's the state of this sad...sad winter.
Northern New England stations barely holding their own.  Most in the top third are half to just under two-thirds their climo total for December and Janaury.

Short of Superstorm '93 seqel...all of the middle Atlantic is down for the count.
Normal season-totals aren't very high to begin with...so all it would take is one good...slow moving coastal to make up current deficits.


Climo columns are the summed monthly totals for DEC and JAN.


Favorite teleconnections finally heading in the right direction over the last 10 days of the month.
