Synopsis
High pressure builds in the west through tonight, then remains
over the region into Monday. A coastal low will likely affect
the region the middle of next week.

Near term until 6 pm this evening
Forecast does remain on track, with winds slowly diminishing.

Only minor updates to temperatures and dew points this
afternoon.

Closed upper low and associated coastal low lift north through
the canadian maritimes today, with trough axis moving through by
early afternoon.

Cyclonic flow remains with a gusty NW flow. Despite deep
mixing, 850 hpa temps of around -5 c will keep temps 7-10
degrees below seasonal normals.

Short term 6 pm this evening through 6 pm Saturday
Deep closed low continues to lift north along the eastern
canadian seaboard, with mean troughing continuing over the NE us
in its wake. At the surface, high pressure builds into the
region from the west. Although a weak backside shortwave will
have a surface trough moving through the region in the
afternoon.

Clear and chilly conditions tonight, with areas of frost across
outlying areas where temps radiatively cool to the upper 20s to
lower 30s. Elsewhere lows generally in the mid 30s.

Continued W NW flow on Saturday, but weaker than today. A
gradual moderation in airmass and deep mixing should allow temps
to rise into the mid to upper 50s. Mostly sunny skies expected,
with just few-sct afternoon CU with shortwave trough passage.

Long term Saturday night through Thursday
The northern branch of the upper level jet will be near to just
south of the region late this weekend and then will be moving
north of the region for Monday. The southern branch of the upper
level jet getting enhanced by an upper level trough near the
gulf early next week will be approaching the region towards
midweek along with the upper level trough. The southern branch
shows some phasing northeast of the region going into next
Thursday with the rest of the southern branch staying south and
west of the region.

At the surface, a large area of high pressure and its
subsidence will keep minimal clouds late this weekend. The high
will move offshore late Monday through Tuesday. During this
timeframe, the airmass will moderate as winds will be lighter
due to a weak pressure gradient.

Towards the middle of next week, particularly starting Tuesday
night is when rain chances return to the forecast. This will be
as a low pressure system approaches from the southeast coast.

The low center itself, appearing in the models as a triple
point, moves across late Wednesday or Wednesday night. Then this
low will move north to northeast of the region Thursday. Its
magnitude remains rather weak so not much of an increase in
pressure gradient is expected. Winds will not increase that much
as a result.

One feature to note though will be the significant precipitable
water. There is some model indication that this parameter will
reach 1 to 1.25 inch Wednesday. This happens to be when most
model precipitation is forecast as well, coinciding with the
most vertical lift. There is a chance there could be some heavy
rain at times as the precipitable water value will be
approaching or even exceeding the 90th percentile for that time
of year according to okx precipitable water sounding
climatology.

The rain will be likely Wednesday into Wednesday evening, with
chances of rain remaining into Thursday as well with the upper
level trough to the west of the region.

Aviation 18z Friday through Wednesday
A weak trough of low pressure crosses the area this afternoon.

High pressure then builds in from the west into Saturday
morning.

Vfr through the TAF period.

Wind gusts around 25 kts are expected through the afternoon.

Winds will then abate this evening, with speeds decreasing to
around 10kt. City and coastal terminals will lose their gusts
after 0z, with inland terminals a few hours sooner. Winds will
range around 10 kts late Saturday morning and afternoon. Wind
direction will start off NW on Saturday, before becoming more
westerly towards the early afternoon for the city terminals.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
