"Depending on thermal profiles, which appear to be right on
the border line of rain vs snow/mixed precip,
the ECMWF solution
could result in another round of heavy snows across much of the
forecast area on Monday (taking its output verbatim results in 10"+
for some spots). However, it`s entirely too early to start sounding
the alarms on major winter storm #2 since the these rapidly
occluding systems have inherently low predictability. And as
yesterday showed, sometimes models can make dramatic shifts in track
and precip types with these occluding systems even 12-24 hours out.
If this storm shows the same southward trends that the last system
showed then the heaviest precip may miss most of our area to the
south. So we will remain in wait and see mode for a few more days
but the system certainly bears watching."
