Synopsis
Low pressure along the ohio and indiana border will shift to the
new england coast tonight. Weak high pressure will build over
the area Friday and Friday night then shift east over the
weekend. This will allow and area of low pressure to move
northeast into the area by Sunday. This system will then linger
over the region into Tuesday.

Near term until 6 pm this evening
Energy rotating around the low should cause the widespread rain over
the east part of the CWA to spread west into early afternoon. This
east to west band should pivot to be more north to south oriented by
evening. However, the hrrr is currently off the mark so overall
confidence is lowered. Rainfall amounts today should range from a
half to two thirds of an in in the far NE to around a quarter inch
or less for the west two thirds. There shouldn't be problems
handling this amount of rainfall so the threat for any flooding
looks minimal.

Widespread cloud cover and rainfall should keep temps from rising
much with highs only in in a 62 to 68 degree range.

Short term 6 pm this evening through Sunday night
The models continue to change from run to run so confidence in
the timing and coverage of any precip during the period is low.

Unlike a couple days ago... It now looks like we may be able to
squeeze out some dry periods the next few days. Expect the
showers to end from west to east overnight as the surface low
shifts to the east coast. On Friday ridging will occur from the
south which will even end the precip threat in NW pa. Lot's of
differences after that with some of the guidance taking a
weak disturbance across the area Friday night into Saturday.

Think this may be a tad overdone and have lowered precip
chances both periods. Best chances for a few hundredths of rain
will be at the southern end of the area. Expect most locations
to be dry on Saturday. Up next will be an area of low pressure
heading out of the plains and likely affecting the area Saturday
night and Sunday. Todays model runs are much weaker with this
system. The previous forecast package already had likely or
better chances those periods and that seems reasonable for now.

Not expecting Sunday to be a complete wash out but there will
likely be a couple periods of rain. Will try to dry things out
from west to east on Sunday night.

Friday will be a tad cool but seasonable readings are expected
both Saturday and Sunday. May have to bump temps up those days
if the models continue to weaken the next system which would
allow for more dry weather and sunshine.

Long term Monday through Wednesday
For Monday, Tuesday, and Wednesday we will have yet another upper
low meandering eastward across the region, although this one appears
to stay north across the central lakes and ontario. Again the
weather will remain unsettled and still have showers mentioned.

There is reasonable agreement too on the broad upper pattern amongst
the models. Smaller features short waves a ways off from being
resolved and will along with diurnal swings modulate the better
chances for precip. There may be a few opportunities for some
thunder, but will leave out that for now with lower confidence.

Memorial day temperatures will be seasonable in the 70s, but as the
cool upper low gets nearby and a cold front crosses Monday night,
temperatures fall back to 60s for most.

Aviation 18z Thursday through Tuesday
Showers with MVFR and local ifr visibilities continue to expand
in the vicinity of the upper low and surface low which are
drifting northeast across the forecast area. Ifr ceilings
across lake erie and some sections of the counties near lake
erie will spread back across the forecast area as the surface
low moves to the east late this afternoon and evening. Winds
will primarily become west-northwest tonight into Friday.

Ceilings will improve to MVFR Friday late morning and afternoon
withVFR conditions developing front west to east Friday
afternoon.

Outlook... Areas of non-vfr likely at times over the weekend.

Marine
Pre-dawn low pressure was located across west central oh. It will
likely track close to the lake shore today. Winds will remain east-
northeast across the lake for a good part of today until the low
shifts across eastern oh. Winds will be strongest first thing this
morning and then pick up again toward Friday morning. Likely not
enough to generate small craft advisory conditions. High pressure
will be over the lake Friday bringing winds around to the south and
southeast by Saturday morning. The pattern will remain active. The
next low is expected to track across northern oh on Sunday. An
approach of a trough for Monday night will bring southwest winds
across the lake Monday.

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.
