413 pm edt Wed mar 29 2017
High pressure will shift to new england on Thursday. Low pressure
will approach from the southern plains on Thursday and drift east
across lake erie on Friday. This system will move off the east coast
Saturday with high pressure expanding across the local area for the
Near term /until 6 am Thursday morning/
High pressure located north of the area will shift to new england
overnight. Upper level ridge will build overhead with mid level
moisture streaming around the ridge. Expect to see the thicker cloud
cover across the western great lakes expand overhead and lower after
midnight. Did raise mins a few degrees for tonight as daytime highs
have already surpassed expected highs by a few degrees. Lows will
range from the lower 30s in NW pa to near 40 in the southwestern
counties. Although we could start to see some echos showing up in
the west late tonight, will keep the forecast dry through 6 am given
the lingering dry air in the low levels.
Short term /6 am Thursday morning through Saturday night/
Deep upper level trough over the plains will lift into the mid-
mississippi valley on Thursday then across central ohio on Friday. At
the surface, a warm front will lift north into the area on Thursday
with the typical delays expected near lake erie. Kept
temperatures in the 40s at toledo with the front not lifting
north of the lake until Friday. Moisture advection will ramp up
across the area on Thursday and expect a leading band of showers
to lift northeast across the area from mid-morning through late
afternoon. Better chances of rain and increasing chances of
thunderstorms will arrive from the west late in the day with the
approach of a 500mb jet streak. Widespread rain with scattered
thunderstorms expected Thursday night but will have to monitor
to see what role robust convection plays that will develop upstream
across the mississippi and tennessee valley.
Surface low will move into northwest ohio on Friday morning.
Some breaks will start to develop in the showers as drier air
gets wrapped into the system. Diurnally enhanced showers will
likely fill back in during the afternoon. As the low pulls away
to the east, northerly flow will pull the cold front south
behind it with cooler air returning Friday night and Saturday.
Qpf on Thursday and Friday is expected to range from three
quarters of an inch to an inch and a quarter unless moisture
transport gets disrupted by the upstream convection. The
moisture depth becomes shallow by Saturday morning with clouds
scattering out from the north as high pressure builds in.
Long term /Sunday through Wednesday/
Overall upper level pattern still progressive with time. Models
suggest periods of ridging with troughiness moving east across the
lower 48. However, deep trough digging into the pacific northwest
will cause amplification of the ridge in the eastern united states
by mid week.
The forecast area will see transitioning periods of waves of low
pressure alternated with areas of high pressure. So, the current
pattern continues through the early and middle part of next week.
This pattern will still keep the polar jet stream well north of the
area keeping the arctic cold air out of the forecast area for the
time being. Some hints indicate a brief shot of cold air by the end
of the week.
Surface high pressure will exit to the east on Sunday allowing a
southern stream low pressure system to move northeast toward the
area. This system will initially have limited moisture associated
with it but will eventually tap into some gulf moisture by Monday
night and force it north into the area. The low will track east
into the carolinas by Tuesday allowing high pressure to build in
from the north. The high will push east to the mid atlantic coast as
yet another storm system with limited moisture begins to approach
from the west on Wednesday.
Aviation /18z Wednesday through Monday/
One fair weather day giving way to another round of inclement
weather over the next 24 hours. High pressure over the local
area will move east and allow low pressure to move into the
region. Expecting lowering ceilings and visibilities along with
some rain shower activity to move into the area west to east.
Best chance for weather will be in the west during the late
morning tomorrow. Lower chances will be in the east. Ceilings
will drop to ifr/MVFR west by morning. Otherwise, expecting
mostlyVFR over the east through this TAF period.
Outlook... Non-vfr continuing into Friday. Non-vfr possible
Sunday night into Monday.
Winds on the lake will be increasing from the east northeast and it
appears waves will be high enough for the western basin to support
small craft advisory criteria. So, will hoist a small advisory for
the western 2 lake nearshore zones from 2 am tonight through 5 pm on
Thursday. For the rest of the marine nearshore, winds should be
just offshore to prevent waves from reaching 4 feet. So, will not
issue an advisory for this area. Otherwise, winds are expected to
be fairly light through the rest of the forecast period except
Monday. Winds will increase out of the east-northeast Monday and
will likely need another small craft advisory then. &&
Marine... Small craft advisory from 2 am to 5 pm edt Thursday for lez142-

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
