Marine Weather and Tides
10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome.
10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name.

A large area of high pressure centered over the canadian prairies
will gradually build to the east across the great lakes region
through Wednesday. This will supply our region with a prolonged
period of fair dry weather with a slow warming trend throughout the
Near term through Tuesday
The upper level pattern over north america features a deep low over
eastern canada with accompanying troughing and a cold NW flow
throughout much of the northeast us, while upstream ridging is found
from old mexico north across the plains, rockies, and well north
into the northwest territories. Further off the pacific coast, a
cutoff low can be found wandering off the ore coast.
The cold and dry airmass overhead with upstream ridging will ensure
clear skies through Tuesday, with cooler than normal temperatures.
At and near the surface, high pressure should MAX out overhead
tonight while the cold airmass slowly moves east. There may a few
cumulus clouds inland on Tuesday, but overall it should be another
sunny or mostly sunny day.
Short term Tuesday night through Thursday night
Little in the way of sensible weather is expected Tuesday night
through Wednesday night as an expansive area of high pressure
remains the dominant weather feature. This will maintain a period of
fair weather. Clear skies and light winds will lead to ideal
radiational cooling conditions Tuesday night with low temperatures
falling into the teens and lower 20s. The center of the high will
slowly drift off to the east Wednesday allowing a southerly return
flow to ramp up. This will allow for a warming trend with
temperatures recovering into the mid 40s to mid 50s on Wednesday,
with milder lows in the lower to mid 30s Wednesday night.
Weak height falls over the area late Thursday Thursday night will
ease a weakening front into the area. Moisture returning ahead of
the front will allow for a band of rain showers to pass across the
area with the front. Activity expected to be relatively light in
nature. Temperatures ahead of the boundary expected to remain on the
mild side Thursday with highs some 10-15 degrees above normal in the
mid 50s to lower 60s.
Long term Friday through Monday
The bigger picture features a broadening trough center roughly over
the hudson bay and extending south across canada on Friday. A
weakening cold front will settle just south of the eastern great
lake, with zonal flow becoming established across the region. A few
showers will linger into very early Friday morning, mainly south of
the buffalo metro area (western southern tier). The weakening cold
frontal boundary will then stall just south of our region across
oh pa. Latest 12z 25 runs of the gfs ECMWF then quickly return this
feature as fast as it left Friday afternoon. Again, it will turn wet
with chances for showers blossoming late in the day. All aided by a
strengthening LLJ (40-50 knots)and isentropic lift as the warm front
arrives Friday evening into Friday night. Otherwise, in between the
shower activity a good portion of the day Friday will be largely
dry. Highs will only be a few degrees cooler as the airmass behind
the front isn't all that cold, upper 40s east of lake ontario and
low 50s elsewhere.
Friday night and Saturday, the warm front slowly lifts north of
western ny becoming oriented SW to NE just to the west of lake erie
and ontario. Meanwhile, a strong shortwave and surface reflection
will pull out of the colorado rockies and towards the lower lakes
overnight. With that said, another shortwave dropping down the
backside of the broader trough will begin to phase with the low
pulling out of colorado. Although, there still remains a bit of
uncertainty regarding timing track at this point which is highly
dependent on the exact positioning of the stalled warm front. If the
warm front does indeed sets up just to our west and across the black
river basin there is an increased risk of flooding east of lake
ontario. All driven by the warm temperatures, expected rainfall, and
snow melt. Have mentioned this in the hwo for the black river and
its tributaries from Friday through Sunday time frame.
Saturday night, low pressure lifts northeast of the lower great
lakes sending its trailing cold front into the region. Look for
widespread rain to transitions over to snow showers fairly rapidly
behind the cold front. There will also be the potential for some
accumulating snows, especially east of lake ontario as temperatures
fall off rapidly (h850 dropping to -10c to -12c) by Sunday morning.
Some additional snow showers will continue to be possible Sunday
with the core of the coldest air aloft moving though the region and
lingering synoptic moisture.
Sunday night, high pressure over the midwest builds east and into
the region with dry and cool conditions Monday. Look for highs to be
slightly below normal in the upper 30s to lower 40s.
Aviation 22z Monday through Saturday
Surface high pressure with mainly clear skies will remain across
the region through Tuesday. WidespreadVFR conditions during the
entire TAF period.
Tuesday through Thursday...VFR.
Thursday night... MVFR with showers possible.
Friday... MainlyVFR, with a few showers.
Saturday... MVFR with showers possible.
Northerly flow will allow portions of the south shore of lake
ontario to experience a short period of small craft advisory
conditions overnight. Otherwise, a large area of high pressure
centered over the upper mississippi valley will gradually build
across the lower great lakes through Wednesday. This will encourage
generally light winds and negligible waves through the period.

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.
