Synopsis
Low pressure continues lifting into the canadian maritimes today
with high pressure building in for the rest of the week. The
high gives way to a cold front late this weekend into early
next week. High pressure builds back in behind the front.

Near term until 6 pm this evening
Low pressure moving into the canadian maritimes today will send
a secondary cold front through the region this morning. Winds
behind the front veer to the NW which will usher in a much
colder and drier airmass. Temperatures may only rise a few
degrees from morning lows due to cold advection taking place
through the day.

Stratocu has made eastward progress, across much of the area,
and sky grids updated accordingly. However, downslope flow
should help to erode some of the cloud cover or at least keep it
scattered as the day progresses. After this morning cloudiness,
mostly sunny conditions are likely to prevail this afternoon as
the low levels continue to dry out.

Temperatures a few degrees above normal in the upper 30s and lower
40s are forecast. High temperatures for the calendar day of january
24 occurred earlier this morning.

Short term 6 pm this evening through 6 pm Thursday
Mean upper troughing continues over the eastern states into tonight
into Thursday morning with another shortwave rounding the base of
the trough. There may be a slight increase in middle level clouds
with this shortwave, but otherwise conditions will continue dry. The
axis of the shortwave moves east of the area by Thursday afternoon
with heights beginning to rise late Thursday as upper ridge
approaches.

High pressure will continue building into the area at the surface
through Thursday. There will be enough of a pressure gradient
tonight to prevent temperatures from completely bottoming out. Lows
will range from the teens inland to the lower 20s closer to the
coast.

Seasonable high temperatures in the lower to middle 30s are likely
on Thursday. There will still be some cold advection and a pressure
gradient for NW wind gusts to around 20 mph. These should start to
subside in the late afternoon as the high begins to settle over the
area.

Long term Thursday night through Tuesday
Overall model agreement noted, with improved consensus in general
pattern when compared to previous runs.

Initially, trough passes east Thursday night into Friday, with ridge
building. Ridge axis moves to the east Saturday in this progressive
pattern, with upstream trough and associated shortwaves approaching
from the west for the remainder of the weekend.

Jet energy dives southward on the backside of the trough, with
amplification noted by early next week. There are some differences
in positioning of this trough as it amplifies across the great lakes
region northeast.

By Tuesday, the trough moves east, with ridge building quickly
behind.

At the surface, high pressure builds Thursday night and moves across
the area Friday. Return flow behind the departing high sets up
Friday night and Saturday. A cold front approaches Saturday night,
and likely passes sometime Sunday with a wave of low pressure
developing along the front. Timing and position remains uncertain,
but rain looks likely during this time frame as moisture increases,
along with lift ahead of the trough, and front.

The front tracks to the east Sunday night and Monday. With the
approach of the upper trough in combination with lingering sfc
trough, could trigger some snow showers, or rain snow showers during
the daytime. Again, timing and positional differences make this
scenario somewhat uncertain. Dry weather returns Tuesday.

A chilly night is expected Thursday night as radiational cooling
likely occurs with the diminishing winds and clear skies. Lows could
range from around 10 in the normally colder locations, to the mid
20s in nyc. Temps rebound to near normal Friday after the chilly
start to the day. Then, WAA will allow temperatures to rebound above
normal, in the 40s to near 50 Saturday.

Another mild day ahead of the front is expected Sunday, 40s and 50s.

Plain rain. Then colder air begins to move back in behind the front,
with a slow downward trend in temps expected Monday and Tuesday.

Aviation 12z Wednesday through Sunday
A cold front approaches from the northwest early this morning.

Canadian high pressure then builds in through the TAF period.

Vfr through the TAF period.

W-sw winds this morning around 10-15 kt with gusts 20-25 kt,
mainly at city terminals. Winds turn more NW after 22z with
gusts subsiding. Winds should remain left of 310 during the day,
however it is possible that they veer to 310 before turning
right of 310 after 00z.
