Synopsis
A weak area of low pressure will move east through the ohio
valley today while high pressure remains to the north over lower
ontario. Low pressure over the central plains will then move
northeast extending a warm front over the area Saturday night
before moving over the area on Sunday. This low will depart the
area by Monday morning dragging a cold front behind it.

Near term until 6 pm this evening
Showers have moved east of the area with only a slim chance
remaining across stark county. Otherwise expect to see the cloud
cover decrease through the afternoon. The most Sun will occur
closer to the lake. Current high temperature forecast looks
reasonable so only made some minor changes to the hourly temps.

Short term 6 pm this evening through Tuesday night
The surface low over the central plains will trek northeast and
will allow for the warm front to move north allowing for the
next round of precipitation on Sunday. The timing of the warm
front and surface low have slowed a bit so precipitation will
likely not begin in the area until after daybreak on Sunday.

Taking a good look at some of the hi-res models, it seems that
the area will get two round of precipitation with the first
being another round of decaying convection this time from
Saturday's severe weather over the middle mississippi river
valley. Once the first round clears, the second round will be
with the surface low and the subsequent cold front. It there is
sufficient time for the atmosphere to recover, there is the
potential for some more robust storms, but there are still
plenty of ifs at this point in time. Temperatures for Sunday
look seasonable with convection counteracting any warm air
entering the region.

The surface low that impacts the area for Sunday will be out of
the area for Monday so a dry forecast seems reasonable at this
time for the holiday. However, this low begins to stall and
deepen over ontario and is progged to extend a wave of energy
through the area on Tuesday, giving the region another chance
for some rain. Tuesday doesn't seem like a washout at this point
but some of this rain may linger into the long term forecast
period as well. Temperatures for Monday and Tuesday also look to
be around normal in the 70s with largely neutral advection over
the area.

Long term Wednesday through Friday
The long term brings us into the first part of june. Temperatures
will still fall short of normals, but not by too much, with an
upper trough that we cannot shake across the great lakes and
northwest flow aloft across the local area. A trough moves
across the lower lakes for Wednesday with another possible
brushing far NE oh NW pa Thursday. So, low precip chances remain
for Wednesday, but the remainder of the work week appears to be
dry for now. By Friday surface high should be more centered
over the ohio valley with the low and troughiness beginning to
pull out across eastern canada.

Aviation 12z Saturday through Wednesday
Outside of where it rained overnight, conditions areVFR. MVFR
and a thin strip of ifr exists where the heaviest rain occurred.

Improvement will take place this morning as the front settles
south of the area. Most will improve toVFR by 16z-18z, but mfd
will likely be the last to improve and may take until mid
afternoon to get toVFR. Light east winds overall, but backed to
the northeast for eri cle this afternoon. Late tonight early
Sunday morning expect MVFR ceilings and possible fog to redevelop
for mfd cak yng at a minimum. Clouds may be thin in spots and
winds are expected to be light variable to calm by then allowing
for the fog and or stratus to develop. Showers and thunderstorms
enter the picture for the extended portion of the cle TAF before
18z sun.

Outlook... Some non-vfr possible across eastern oh inland NW pa
Sunday morning. Areas non-VFR conditions Sunday Sunday night
with showers thunderstorms.

Marine
While a weak low crosses central ohio today, high pressure will
reside across the lake with fair conditions after this mornings
showers pass. This will continue to be the case into Sunday morning.

On Sunday, though, low pressure will track across il in and toward
the western basin of the lake by evening. East-northeast winds will
come around to the south and then shift to the west Sunday night.

Winds are not overly strong, but do pick up Sunday night in the
wake of the cold front. The lake will remain fairly stable
limiting the winds Monday and Tuesday, but the possibility
exists for small craft advisory conditions with the west-
southwest flow across the far east end. A trough is expected to
cross the lake for Wednesday.

Cle watches warnings advisories
Oh... None.

Pa... None.

Marine... None.

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.
