The main forecast challenge for the extended period is Fri into Fri
night as digging northern stream shortwave moving into the Gt Lakes
tries to capture a coastal low moving off the mid Atlc coast. Still
a lot of spread in potential storm track and intensity but consensus
of the ensemble suite is the storm remaining far enough offshore for
just a glancing blow. However, it`s still day 4 and there are some
members with a more significant impact. It will depend on the
amplitude of this northern stream shortwave and if it can back the
flow enough for a low track closer to SNE. At the very least, a
period of light snow is anticipated, with greater probs near the
coast, but can`t rule out a more significant impact.
