It's all going to combine with a low pressure system that stretches from
Baffin Island to St. James Bay. There's a significant amount of energy in the
form of cold Arctic air in that cyclone.

It's getting some, but mostly in the form of rain. They need snowpack to
provide meltoff during the summer to keep the reservoirs filled, and that is
not happening.

That high pressure ridge is not in place yet due to a low pressure trough
streching from south central Canada to Texas. The beginnings of the high
pressure ridge are presently sitting over the intermountain region. That
nor'easter will be affecting New England into Wednesday. It's still far too
early to say for certain, but there is the potential for a significant storm
over the northeast US and eastern Canada the following weekend.

Yes, and we have our own manifestations out here. I posted a hazardous
weather notice for the southwest on a hiking list this morning.
