A Seasonal Start to 2013, Then it Gets REALLY Cold!
The Arctic Assault Arrives Tonight and Lasts the Next Three Days!
Good Morning and Happy New Year!
We have a quiet start to new year. There will be a few sprinkles and flurries around, but all-in-all it
will be fairly quiet with a little hit-or-miss activity around the region. The set up is a storm to the
south will spread some light moisture northward that will be captured in the mid-level jet, then on
top of that getting drawn in from the arctic boundary will further add to some lift over the area.
Again, not much to work with so we shouldn't play up precipitation very much today.
Tonight we get into drier air with some subsidence from the confluent flow and resultant high
pressure. So skies will clear and temperatures will drop.
Tomorrow will be a colder day, but still fairly nice with plenty of sunshine as high pressure
maintains its presence. Thursday will be quiet still with sunshine to start, then some more
afternoon clouds starting to fill in during the afternoon. These clouds will be moving in ahead of a
storm system diving southward out of Canada. Actually the feature is a combination of two shortwave
troughs combining over southern Ontario then moving through New England. The first of
these pieces is moving eastward from southern Alberta this morning and the second piece is
diving southward out of the NW Territories. As this system moves through New England there will
be a few snow showers well to our north, but just a few clouds around here.
Previous runs of this system had the front pushing southward and causing a cold shot for Friday.
Now it looks like another SW trough will hold the front up to the north keeping us in the "milder"
air. So we'll be making a bump up to Friday's temps and without a need for recovery from arctic air
on Saturday we'll be taking those temps up as well with a milder start Friday night/Saturday
Another system will move into the area on Sunday with more clouds, but both the GFS and EURO
are lacking moisture, so there may be a flurry, but it will as likely be dry. At the very least we will
increase the clouds, but leave it dry.
Have a Great Day and Happy New Year!
