Low pressure passes well to our south and out to sea early Monday. High pressure takes over by Tuesday and settles in for Wednesday and Thursday as well. An ocean storm may impact the area Friday.
I know the calendar says March but Mother Nature could care less. Although this latest storm system was essentially a miss to our south we are not going to avoid the continued cold temperatures all this week as temperatures run 15 to at times near 20 degrees below normal through Wednesday. For that matter we can expect near record cold readings tonight.
As the storm pulls away skies partially clear today as another chunk of very cold arctic air settles in overhead. Tuesday starts bitterly cold with afternoon highs 15 degrees or more below normal despite a fair amount of sunshine.
An upper level disturbance keeps a lot of clouds around Tuesday night through Wednesday night with just a chance of an isolated flurry or snow shower as the arctic air remains entrenched throughout the region.
By Friday the coastal storm moves off the US Southeast coast and tracks northeastward. How close it comes and how much it strengthens is still very much in question. Temperatures will moderate by late week, although remaining below normal, easing some of the discomfort from what seems to be a never ending cold snap this winter.
One last note. Meteorological winter is the three month period from December 1st through February 28th. These are the three coldest months of the year as agreed upon by weather experts. Here in Boston temperatures through this period were the coldest since 2002-2003, averaging 29.9 degrees. It was the 9th snowiest with 56.4 inches of measured snowfall at Logan Airport in east Boston. Temperatures averaged below normal each of the three months with the coldest month being February with a -2.7 average below normal. Snowfall was 23.6 inches above average for this period. So, to say it was a cold and snowy winter period is an understatement and one we knew anyway. With the long range outlook through mid March it seems that Old Man Winter is not done with us just yet.
