Synopsis
High pressure overhead today will shift east for Sunday. Low
pressure from the central plains will track east to the ohio
valley by Monday morning while a cold front sinks south across
the area. A more expansive area of high pressure will settle
south across the great lakes and the upper ohio valley for later
Monday through Wednesday.

Near term through Sunday night
Very dry atmosphere out there today and not a cloud in the sky.

Skies will remain clear for the first part of night. Should
have a good radiational cooling night for the sheltered
locations, especially east. High clouds will begin to overspread
from the west during the second half of the night. Will go with
20s for lows for most.

Sunday we will be on the backside of the high with light south
flow and just some slight warm advection. Temperatures will
reach about where they should be for this time of year. Bigger
question will be when will the rain arrive. General trough
across the great lakes will push across the eastern lakes and
bring a cold front south across the lake Sunday evening. Low
pressure from the central plains with an opening wave will track
easterly across the lower ohio valley. Rain will focus primarily
south of us 30, but additional rain expected with the northern
front sinking southward. Will start to bring in the rain chances
late in the afternoon. Eventually the column moistens and
moisture will focus along the warm front. Colder air will be
pushed in with the sinking cold front. Will have the majority of
the precip type as rain, but as it ends may have a mix with a
few wet flakes. Some drizzle is also possible with the shallow
moist layer that remains toward Monday morning.

Short term Monday through Tuesday night
Improving conditions are expected during the day Monday as the
cold front drops farther south away from the region. There could
be a lingering chance of light snow or rain Monday morning
mainly south of us route 30 before drier air fully moves south
into the region. Temperatures will start in the 30s and drop
some during the morning before recovering a few degrees around
noon.

Cool high pressure will build over the region Monday night and
Tuesday and shift east Tuesday evening. The high pressure area
will move off the new england coast on Wednesday. Fair skies can
be expected across the region during this period with a gradual
warming trend. 850 mb temperatures will bottom out from -7 to
-10c Monday night and warm to +2 to 0c on Wednesday. Surface
temperatures will respond especially with plenty of sunshine.

High temperatures on Wednesday will reach the lower 50s.

Long term Wednesday through Saturday
A generally mild period is expected but forecast uncertainty
increases during this period as the GFS and ECMWF diverge with
the approach of a short wave from the west. The GFS is faster
and more progressive while the euro is slower and develops a
surface low on the approaching cold front. Either way mild
springlike conditions will prevail ahead of the front and the
chance of showers will increase. The more recent run of the euro
shows a less intense low pressure center passing by to the
north and west of the region.

Aviation 18z Saturday through Thursday
High pressure and very dry air across the terminals for today
and therefore no cloud cover to speak of. That high shifts east
Sunday and mid high clouds approach from low pressure to our
west across missouri after 18z. Light northwest winds this
afternoon will back to the southwest for tonight and Sunday.

Outlook... Non-vfr possible in light rain Sunday night into
midday Monday.

Marine
Rather tranquil conditions are expected over lake erie
overnight as high pressure near the lake gradually shifts
southeast to off the virginia coast by Sunday morning. Northwest
winds 5 to 15 knots will shift to the southwest after midnight.

Southwest winds will continue into the early evening ahead of a
cold front that will be dropping south across the lake before
midnight. High pressure will build eastward north of the area.

The pressure gradient will tighten by morning and generate north
to northeast winds around 20 knots which will persist Monday
morning and gradually diminish in the afternoon. A small craft
advisory will likely be needed late Sunday night.

High pressure will build eastward over the eastern lakes
Tuesday and early Wednesday and winds will be light. South to
southwesterly winds will increase Wednesday night and Thursday
as the high pressure area moves off the new england coast.

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.
