Ha, Like they read my mind.....
A major pattern shift commences thereafter with building heights and
a warm trend, especially aloft, heading into the weekend. A northern
stream clipper crosses Quebec early in the weekend which
provides another chance at light rain or snow and a reinforcing
shot of cold advection. This could set the stage for a complex
mixed precipitation event as warm frontal/overrunning
precipitation renews along the stalled front by the middle and
end of the weekend in response to approaching southern stream
shortwave trough moving SW to NE. This of course is highly
dependent on the position of the stalled front and thus the
southern extent of a cold low-level airmass; at this time there
is model agreement that strong high pressure over ON/QC will
provide cold flow from the north enough to push and keep this
boundary south over southern New England Saturday night.
We still have broadly diverging solutions to contend with at
this stage regarding impacts with some solutions suggesting
cool temps through the column yielding a rain/snow mix, but
others place warm temperatures aloft over cool surface
temperatures which would result widespread ice or sleet Saturday
night into Sunday. Anomalously high heights allow a juicy
airmass to develop with PWAT presently progged to exceed 1.0" by
early Sunday, 3-4 standard deviations above normal. Total QPF
could thus be on the order of 2-3" where the boundary sets up
with models for now placing the axis of rain from northern New
York state extending eastward into central and northern New
England.
