Synopsis
High pressure will slowly move east across the area and be over
eastern new york and pennsylvania by Monday morning. Low
pressure will remain nearly stationary over the tennessee valley
region Monday and Tuesday and then move east to the carolina
coast by Tuesday night. A trough will extend north from the low
into the local area Tuesday and Tuesday night.

Near term through Sunday
Some indications of an upper level rex block develops over the
western united states and the whole package moves ever so slowly
east over the next few days. This overall pattern will keep a
strong surface high pressure present over the forecast area and
it eventually moves slowly east to eastern new york and
pennsylvania by Monday morning. The surface high will dominate
the local area through this forecast period.

The only issue of concern is a fairly large swath of middle and
high level moisture streaming east during the day today. Most of
the cirrus appears to be thin and should allow ample sunshine
across much of the area. The exception will be the southwestern
portions of the area where the cloud deck will be thicker and
even some mid level clouds will persist. We go back to mostly
clear skies tonight into Sunday.

Temperatures will be under the influence of north to northeast
flow today; albeit light. This will keep temperatures in the
middle to upper 50s across the area. Exception today will be the
lake shore where highs stay in the middle to upper 40s today.

Tonight we will see radiational cooling in the clearing skies
and winds diminishing to light calm across the area. However,
expecting lows to fall into the lower 30s in the northeast and
middle 30s elsewhere. A similar temperature profile will occur
Sunday with the persistent northeast flow off the lake. Lake
shore area will struggle to get out of the lower 40s while the
inland portions of the area will be in the upper 50s to around
60 degrees for a high.

Short term Sunday night through Tuesday night
Surface high pressure will be located east of the area by Sunday
night with a light easterly wind providing some mixing to keep
temperatures higher than the previous few nights. Raised mins a
degree or two into the upper 30s to lower 40s. Monday is expected to
be the warmest day of the week as winds shift around to the
southeast and limit the lake influence. Mostly sunny skies expected
into the afternoon before cirrus starts to thicken. Temperatures at
925 warm to 13-14c and expecting all areas to be in the 60s.

Moisture will begin to increase across the area from Monday night
into Tuesday as an upper level low drifts northeast from the
tennessee valley into the ohio valley. Will introduce a low chance
pop as early late Monday night into the southern counties, expanding
northward on Tuesday. Better chances of rain will be in eastern
areas Tuesday night as moisture continues to be pulled north ahead
of the upper low and interacts with a trough passing to the
north.

Long term Wednesday through Friday
Chances of rain linger in the east on Wednesday morning then
decrease through the afternoon as the upper level low opens and
shifts east of the area. Will trend temperatures downward a few
degrees on Wednesday as northerly flow develops off the lake.

By the end of the week, models all indicating a series of upper
level waves moving southeast out of canada will work to carve out
another trough across the eastern united states. Timing these
individual features is still up in the air but it looks like some
colder air may arrive again by Friday or Saturday.

Aviation 06z Saturday through Wednesday
High pressure will dominate the local area through the next 36
hours and bring fair weather to the region. Latest satellite
imagery shows some high clouds and even some mid level clouds
streaming east toward the area. Models indicate this high and
mid level moisture will gradually work its way east across the
area later this afternoon into the evening and then move out of
the area. Other than that, winds will be light and variable
through the forecast period.

Outlook... Non-vfr possible Tuesday into Wednesday.

Marine
A generally good stretch of marine conditions expected through
Thursday, although water temperatures remain quite cool near 40
degrees. A large area of high pressure over the great lakes region
will build to the new england coast through Monday. Light winds
today will become easterly at 10-15 knots on Sunday, allowing waves
to build to 2-3 feet in the nearshore waters on the west end of the
lake. Easterly flow continues through Tuesday before finally backing
to northeast as low pressure moves up the east coast on Wednesday.

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.
