Latest discussion from NWS Albany about mid-late week potential if anybody cares.
Wed night into THU...A full latitude positively tilted mid and
upper level trough moves into the Central Plains with a strong mid
and upper level jet along the eastern portion of the trough over the
eastern CONUS. Initially over running pcpn could break out Wed
night with snow or a mixture of pcpn types. For now, we continue
snow and rain as the main ptypes but the GEFS/ECMWF are indicating
some sleet and freezing rain may be possible. Also, some light to
moderate snow accumulations are possible. We will continue to
wait for a non cacophonous tune from the medium range
deterministic and ensemble guidance. Lows in the mid teens to
20s are likely Wed night with mainly mid 20s to mid and and
upper 30s on Thu.
Thu night through Friday...A large amount of spread continues in the
guidance here with the 12Z ECMWF indicating the mid and upper level
longwave trough becoming negatively tilted with the primary sfc wave
remaining west of the northern Appalachian Mtns, which would support
a warmer solution, while the 12Z CMC and some of the NAEFS/GEFS
are similar, the latest WPC shows support with an an occluded
front moving through. The 12Z GFS has a coastal wave moving from
the Delmarva Region to eastern Long Island Friday morning with
a decent snow event for a large portion of the area. WPC does
not favor this scenario, and based on the muddled and chaotic
medium range guidance we are not confident in the 12Z GFS
either. The 12Z GFS has a much flatter mid and upper level
trough too. Needless to say, a moderate to heavy pcpn system
with rain/snow or mixed pcpn is possible. It could also be windy
depending where the primary cyclone tracks. Temps still look to
run above early FEB climatological normals.
