Synopsis
High pressure centered along the atlantic coast will keep dry
weather over the ohio valley today and Sunday. A cold front and
wave of low pressure will bring showers on Monday. Showers will
linger on Tuesday when an upper trough is forecast to move in
from the northwest.

Near term until 6 pm this evening
High pressure centered over the appalachians this morning will
shift slowly east through this afternoon. This will allow for a
continuation of some mid and high level clouds to push overhead
through the day today, leading to partly cloudy conditions. In
light southerly flow on the backside of the high, expect highs
today in the mid to upper 70s.

Short term 6 pm this evening through 6 pm Sunday
High pressure will continue to progress northeast to the
canadian maritimes on Sunday. No precip is expected again,
though clouds will increase as moisture transport grows ahead
of a cold front and upper trough. Even with diminished
insolation, continued warm advection will allow highs in the
mid and upper 70s.

Long term Sunday night through Friday
Weather pattern change to take place with mid level ridge shifting
east and long wave trof settling across the northern tier of state
and into the great lakes early next week.

Model solutions continue to trend toward a slower onset of
precipitation. Therefore, have held off pcpn until late Sunday
night with the approach of surface cold front.

Model solutions continue to differ on timing of long wave trof and
therefore the track of southern cutoff mid level low. These
differences will affect the amount of QPF and placement of heavier
rain axis.

Will ramp pops up to likely early Monday afternoon and categorical
during the late afternoon into Monday night as surface wave develops
along the surface front. Expect cooler temperatures Monday with
highs in the upper 60s west to lower 70s east .

Rain event of 1 to 2 inches will be possible early next week but due
to the uncertainty of the interaction with the cutoff low,
confidence in placement of the heavier rain axis is low. Have a
mention of moderate rain Monday afternoon into Monday night.

Long wave mid upr level trof to settle into the great lakes ohio
valley at mid week. Model solutions have trended deeper with this
feature. This will keep a chance of a shower in the forecast with
the highest pops north Tuesday. Highs Tuesday are expected to be a
little below normal, and generally between 55 and 60.

A secondary S W trof to drop down into the mean trof position
keeping the threat of showers in the fcst Wednesday. Wednesday looks
to be the coldest day of the week with highs in the lower 50s, which
is 10 to 15 degrees below normal. Depending on cloud cover, frost
will be possible Wednesday night with lows in the mid upr 30s.

After a cold start, temperatures will moderate some on Thursday with
highs in the upper 50s to near 60.

Flow backs with next front approaching the area late in the week
into next weekend. Latest ECMWF solution is more amplified and
therefore slower than progressive gfs. Due to low confidence have
limited pops to low chance Friday afternoon west and then across the
area Saturday. Temperatures will continue to moderate with highs
Friday of 60 to 65. Clouds and pcpn will hold temperatures down
Saturday with highs of 55 to 60.

Aviation 14z Saturday through Wednesday
Look forVFR to continue except at luk where fg br is reducing
visibility early this morning and again early Sunday. Will
continue to monitor other TAF sites for possible br formation.

Otherwise expect cirrus and altocumulus to overspread all sites
under surface high pressure well ahead of a deepening upper
trough. Winds from the south will increase close to 10 knots
this afternoon. Cvg will see similar conditions after 12z
Sunday, with precip probably holding off until Sunday night.

Outlook... MVFR ceilings and visibilities possible Sunday night
through 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.
