Synopsis
High pressure will build in from the west over the lower great
lakes by Wednesday. The high will move northeast to maine by
Thursday. Low pressure will move northeast to the ohio valley by
Thursday and then shift to the east coast by Thursday night.

High pressure will build up the appalachian mountains Saturday
with a cold front moving east across the local area Saturday
night.

Near term through Wednesday
Update... Will continue trend of decreasing snow showers off
lake erie across northwest pa although did lower pops to
likely chance from categorical. Minor sky cover adjustments as
well but no big changes for overnight update.

Original... Satellite imagery and regional radars shows lake
enhanced and lake effect clouds and scattered snow showers this
afternoon. 850mb temps advecting in over the region are -10c to
-12c. These colder temperatures aloft are causing about 50 to
100 j kg of MUCAPE and instability. Using area twdrs and mosaic
imagery shows bands of light snow developing over the lake this
afternoon and impacting the primary snowbelt region east of the
cleveland area. We followed the guidance from the hrrr and
namnest closely with several bands expected to develop and
impact far northeastern ohio into northwestern pennsylvania. At
this time, we will mention the possibility of 1 to 2 inches
across NE ohio and 2 to 4 inches with isolated higher amounts
across crawford and erie counties in pennsylvania. At this time,
we will not issue an advisory for the primary snowbelt areas.

But if more snow is anticipated this evening, a quick headline
may need to be issued.

Lake effect cloud cover will hold on for downwind of the lake
this evening and overnight with so eroding of the clouds during
the day on Wednesday. Coldest temperatures will be closer to
western and central ohio tonight with readings down to near 20
degrees. Tomorrows highs will be mostly depending on the amount
of sunshine but mid 30s are expected across much of the area.

All lake effect snow showers will be done and fair skies late on
Wednesday.

Short term Wednesday night through Friday night
Little change in the short term forecast. Coastal low will
develop and track up the east coast Thursday, lifting a trough
across the forecast area. Nice WAA pattern setting up. Expect
some light snow to develop from the south in the morning,
gradually changing to rain over entire area by late afternoon.

Potential for a brief period of sleet or freezing rain as precip
transition with overrunning. Bulk of the precip will have
exited the area by daybreak Friday as low tracks into new
england. Potential for some lake effect snow showers in the snow
belt on Friday.

Long term Saturday through Tuesday
Below normal conditions continue through the long term
forecast. Models continue to differ on the timing of the next
cold front. The ECMWF moves the weak front through on Saturday
while the GFS holds off until late Saturday night into Sunday.

With so much doubt in the timing will continue with low chance
pops Saturday into Sunday.

Aviation 00z Wednesday through Sunday
Expect slowly improving conditions through the night and into
Wednesday as high pressure and drier air move in from the west.

Will need to hang onto snow showers keri for a few more hours
but do not expect visibility restrictions. Otherwise there
biggest threat for patchy MVFR CIGS at kmfd, kyng and kcak
mainly through the evening. Otherwise expectVFR.

Outlook... Non-vfr possible Thursday night and Friday.

Marine
Updated... Winds a bit higher on the west end than earlier
anticipated so issued a small craft advisory. Winds will be
coming down through the early overnight period so will end at
4am.

Original... Small craft advisory will continue into tomorrow
with NW flow of 15 to 25 knots. Winds diminish from the west
tomorrow as the low tracks across quebec, and high pressure
builds over the lower lakes. Winds shift to the S to SE tomorrow
night as the high moves east of the lake. Another coastal low
develops and deepens to 29.40 inches off the mid atlantic coast
by Friday morning, with a trough across the lower lakes. A small
craft advisory will be needed.

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.
