Sunny & Seasonal for the Last Day of 2012! But Arctic Cold for the Start of 2013!
Real Feel Temperatures Only in the Teens Wedneday and Thursday!!
We've got some dry and seasonably cold weather this morning... and a whole lot less wind,
because the low pressure system responsible for Saturday's snow continues to drift out into the
North Atlantic... A weak ridge of high pressure will temporarily be in control of the weather pattern,
although the satellite imagery early today is showing areas of low clouds in eastern Pennsylvania
and across parts of upstate New York... Because there won't be very much wind today, it'll be
difficult for any sufficient mixing to occur, and for clouds to get 'stirred out' of those places that
will be overcast at daybreak... But, there will be a few glimpses of sun for a while today, especially
along the immediate coastline -- and that sun will tend to fade behind increasing clouds from
midday on... Most temperatures will be in the upper 30s this afternoon, but it won't "feel as harsh"
as it did yesterday, because of the lack of strong wind gusts...
Tonight, for New Year's Eve festivities, we'll be watching for some spotty, light precipitation across
the Northeast and in the mid Atlantic states... Some slightly warmer air moving in aloft on a
southwesterly wind could bring with it a few flurries late tonight, and there may even be a steadier
snow shower in a few areas (especially in those places that are located away from the coast, and
north/west of I-95)...
Tomorrow, the leading edge of some colder air may bring with it a few flurries and sprinkles...
Southwest winds should keep the temperature from falling below the freezing mark tonight, and
that will provide the mercury with a sort of 'springboard' for tomorrow -- with many places winding
up in either the upper 30s or the lower 40s in the afternoon... But, after that, there will be partial
clearing and some noticeably colder air should be arriving on New Year's Night... Expect
temperatures to plunge into the 20s (even the teens in the typically colder spots) late Tuesday
night, and then Wednesday and Thursday will be dry, but cold... Many temperatures during
midweek will be in the low or mid 30s, even despite some sunshine... The core of the coldest air in
eastern North America, or the "polar vortex" appears as if it will be across Quebec and in northern
New England... Therefore, we don't think that the coastal cities will experience a "brutal" cold
snap, but this should still provide us with the season's coldest air thus far... And, while we're not
anticipating any major storms / precipitation events this week, the initial push of arctic air during
the Wednesday/Thursday time frame will be followed by a reinforcing shot of cold air on Friday...
There'll be a 'clipper-type' disturbance located in the Great Lakes Thursday, which will probably be
dragging a cold front across the Northeast and mid Atlantic states on Thursday night... And, that
will probably make Friday the coldest day of the upcoming week -- even if temperatures are just
two or three degrees lower than Wednesday or Thursday... Have a good day!!!
