Synopsis
Low pressure over north carolina will track northeast along the
atlantic coast today drawing a cold front east across the local
area. High pressure will build across the region tonight
and Thursday ahead of a cold front that will move east across
the region on Friday. A second cold front will quickly follow
Friday night as another low drops across the great lakes.

Near term today through Thursday
Low pressure over north carolina will track northeast to new
jersey by evening. Moisture over the region early today will get
pulled east with the low through the day as high pressure
builds in from the west. Low level moisture however will be slow
to exit. Will keep clouds in the east through the day and break
up clouds west during the afternoon. Will begin with likely to
categorical pops east and chance pops elsewhere for light rain.

For the afternoon will drop the east to a chance and remove pops
west. Overnight, both the NAM and GFS hold onto low level
moisture northeast while drying out the rest of the area. Based
on this will hold onto clouds east northeast much of the night
with clearing continuing elsewhere. For Thursday again both
models actually expand 850mb rh 80% or better across the area
although given high pressure will be over the area will side
with the optimists and go with pc.

Short term Thursday night through Sunday
A southern
stream system that largely bypasses the ohio valley Thursday
will shift across the appalachians and move to the mid- atlantic
coast Friday. That will leave high pressure weakly in place
across the local area Thursday night. A weak cold front, lacking
in moisture and much lift, will cross the area on Friday. This
may bring an isolated or scattered shower with it. It has been
consistently advertised as having limited impact. A stronger
shortwave digs into the base of the trough across the great
lakes later Friday. This has a little more potency and may bring
a shower to northern oh NW pa Friday night into Saturday
morning. Then Sunday we begin the transition to ridging aloft
with high pressure at the surface. Temperatures will be near
normal Thursday night Friday, slide back some for Saturday and
then begin to warm for Sunday. Sub- freezing lows are possible
Saturday night across northeast oh NW pa especially if we get as
much clearing as we are expecting.

Long term Sunday night through Tuesday night
Early next week is looking to be terrific. High pressure sets up
across the southeast u.S. Bermuda by Tuesday. The ridge aloft builds
into Tuesday and southerly flow will bring much warmer temperatures
to the region. Precip will stay out of the forecast.

Aviation 06z Wednesday through Sunday
Low pressure over north carolina will turn northeast and move up
the east coast today. Moisture associated with the system has
spread light rain with MVFR and ifr restrictions across the
area. Most ifr was across western oh, west of an inverted
surface trough. Am expecting the ifr to spread east late tonight
and Wednesday morning as the trough pulls east out of the area.

Expecting a mix of MVFR and ifr Wednesday morning with
conditions lifting to MVFR most places late morning into
afternoon. Expect improvement toVFR from the west mid late
afternoon.

Outlook... Non-vfr Wednesday evening into early Thursday mainly
east.

Marine
Areas of fog will remain on the lake until the cold front across
southeast mi crosses today. That cold frontal passage will shift
winds around to the north-northwest and increase them to 15 to 20
knots for a short time this afternoon evening. This will be enough
for a short small craft advisory across the central third of the
nearshore waters this evening. After this brief uptick in winds
conditions settle with high pressure shifting over the lake for
Thursday Thursday night. A weak cold front crosses the lake Friday
followed by another late Friday night early Saturday morning. This
will make for a little chop across the east half of the lake on
Saturday. High pressure builds across the ohio valley and lower
lakes for Sunday.

Cle watches warnings advisories
Oh... None.

Pa... None.

Marine... Small craft advisory from 6 pm this evening to 4 am edt
Thursday for lez146>148.

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.
