Wind Chill Advisory 6, NWS Caribou, ME

Area Forecast Discussion
National Weather Service Caribou ME
1208 AM EST Fri Mar 10 2017

.SYNOPSIS...
Weak high pressure will build over the area overnight. A small
low will track off the Mid-Atlantic coast Friday morning and
pass south of the Gulf of Maine Friday afternoon. High pressure
building in from western Canada will push bitter cold Arctic air
across the region on Saturday.

&&

.NEAR TERM /THROUGH TODAY/...
12am Update...
Forecast in good shape and no changes needed. Snow showers and
squalls are finally dying off and should be gone within the next
hour or two.

Previous Discussion...
Winds will diminish later tonight w/snow squalls ending. On
Friday, our focus will be on a small low tracking off the Mid-
Atlantic coast and sliding south of the region. Latest guidance
shows an inverted trough extending northwest from this low which
may bring some light snow, or perhaps a localized Norlun event
to southwestern Maine on Friday. The low should slide far enough
to the south keep it's precipitation offshore and mainly south
of our region. However, there is a chance it could brush the
Downeast coast with some light snow so have included a small
chance for snow over southern Downeast areas on Friday. Northern
areas will be partly sunny and cold.

.SHORT TERM /TONIGHT THROUGH SUNDAY/...
Arctic air wl be bleeding into CWA Fri ngt as strong H5 closed low
takes up residence along the St. Lawrence. Nrly flow wl continue to

the coast Fri night thru early Sat mrng. Hv adjusted pops up
slightly to accnt for the potential along the Hancock coast and
possibly as far north as BGR.

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
Hi pres builds in at the start of the long term with minimal wx
expected early in the week. All med range guidance is now
indicating nor'easter for the middle part of the week, tho they
differ on timing. By 00z Wed, EC/GFS and CMC indicate coastal
low wl be sitting off the coast of Cape Cod. Model projections
indicate rapid cyclogenesis in the Gulf of Maine Tue night with
possibly significant accumulations of snow once again. Depending
on how strong sfc high ends up being wl determine how far north
the hvy snow gets. For now hv gone abv Superblend with likely
pops acrs most of the area Tue night and Wed with the exception
of the far northwest zones.
