00z aviation forecast and mid evening update...

Synopsis
A cold front positioned from southwest ontario canada and
across northwest ohio will slowly sink further into northern
oh northwest pa tonight. Low pressure across the lower
mississippi river valley will slowly move northeast reaching the
ohio valley by Saturday night. This low will then continue east
to off the mid-atlantic coast by Sunday night. A cold front
will then move across the great lakes region on Sunday night
into Monday. High pressure will build across the area for the
middle of next week.

Near term through Saturday night
There were no changes made to the on going forecast. Just
adjusted some cloud cover and hourly temperature trends.

Previous discussion...

little change for the forecast for the near term. Still just
fine tuning the northern extent of the steadier rain shield.

Temperatures overachieved today and reached into the lower and
mid 50s with a bit of added Sun that stuck around longer.

Expect fair conditions to continue through the evening and
really do not have anything more than a slight chance well
south of us 30 for much of the night. The low makes its closest
approach to the ohio valley Saturday evening and at that point
bringing the precip chances to its furthest north position.

Expect lows in the mid upper 30s both night. As far as highs go
Saturday, guidance is hinting at another day of locations
hitting 50, but took a slightly conservative route with the
northeast flow expected across the area.

Short term Sunday through Monday night
Low pressure will be passing to the south of the region on
Sunday with rain chances slowly ending from west to east through
the evening. The region should be between storm systems Sunday
night with quiet weather. The next trough axis to cross the
central great lakes looks to be by midday on Monday with some
lake effect rain to snow possible into Monday night. Some light
accumulations may occur Monday night across NE ohio into NW pa.

Highs Sunday should be in Thu 40s but will drop to near 30 by Monday
morning. Highs Monday will be cooler with highs in the middle
30s.

Long term Tuesday through Friday
High pressure will take control of the region on Tuesday with
dry conditions. The high will shift off the middle atlantic
coast Tuesday night but the region should remain dry into at
least Wednesday night as the next storm system moves into the
upper great lakes. Timing between the models is uncertain on how
soon the rain will start on Thursday into Friday so have only
gone with chance pop's.

Cool on Tuesday with highs mostly in the 30s. Warmer Wednesday
into Thursday with highs into the 40s on Thursday. If the upper
trough passes by Friday it will be cooler with highs dipping
back into the 30s.

Aviation 18z Friday through Wednesday
The aviation forecast is a little challenging with guidance
showing some significant drop in ceilings and visibilities later
tonight into early Saturday morning. We will not go as low as
guidance with this update but we will trend downward the ceiling
heights and some visibilities drops.

Most areas are seeingVFR as of early evening but we do expect
all areas to see MVFR later tonight and some places dropping to
below 1k feet especially for tol, fdy, mfd, and cle. Some
guidance even shows lifr but will not go that low yet. The other
taf sites will likely see ceilings between 1500 to 3000 feet.

MVFR visibilities will hold on tight for much of the day on
Saturday with some drops in visibilities by afternoon with light
rain and mist moving in. Winds will becoming more northeasterly
this evening and overnight between 5 and 10 knots. Some gusts
up to 20 knots will be possible by late Saturday morning through
the afternoon.

Outlook... Periods of non-vfr CIGS vsbys expected through the
weekend with rain. Non-vfr possible across far northeast
oh northwest pa Monday into Tuesday.

Marine
Low pressure will gradually shift northward to the ohio river
valley on Saturday. As it does winds will shift to the northeast
overnight increasing through Saturday morning. Winds should
increase enough to by mid morning on Saturday to build waves to
3 to 5 feet across much of the nearshore waters. Winds will
remain high enough to keep this height of waves going into
Sunday morning. There will then be a lull between storm systems
Sunday night. However by early Monday morning southwest winds
will be on the increase. A trough will pass by Monday afternoon
and continue into Monday night with northwest winds increasing
in its wake. So another small craft advisory may be needed.

Cle watches warnings advisories
Oh... None.

Pa... None.

Marine... Small craft advisory from 10 am Saturday to 9 am est Sunday
for lez142>149.

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.
