Synopsis
High pressure over the eastern great lakes today will weaken
and shift east Tuesday. This will allow low pressure to track
across the northern lakes, forcing a cold front across the area
Wednesday evening.

Near term until 6 am Tuesday morning
No change in the overnight forecast. Strong upper ridge remains
anchored over the forecast area with only weather to contend with a
cirrus shield over the area. Well above normal temps continue with
low from the upper 50s into the lower 60s.

Short term 6 am Tuesday morning through Thursday night
Change in the weather pattern is on the way. Upper level ridge
finally weakens allowing surface cold front to move into the central
great lakes by daybreak Wednesday.

For the third day in a row have removed precip from northwest ohio
for Wednesday. The models have been consistently showing the precip
threat with the front is primarily over the east end of the area.

Since our neighbors to the west and north have dry forecasts I think
it is reasonable to go dry especially given the models. Even in the
east see no need for anything more than a 20 pop given how dry the
atmosphere is. The front should be southeast of the area by 18z.

Still think the forecast guidance is too cool for highs as it will
likely be 80 by 9am like it has been the past several days. Will
continue with a high forecast similar to the previous few days. Cold
air advection will continue through the end of the short term
period. Another cold front will cross the area on Friday. Temps
will get chilly behind this front with 850 mb temps dipping to
around plus 4 by 00z Saturday. At the same time 500 mb temps will
get colder than 20 below which means the lake to 500 mb temp
difference will be about 40 degrees. So... Not only will showers be
likely downwind of the lake on Friday... A few rumbles of thunder
could also occur. Will go with 50 pops for now but suspect we will
eventually need likely or higher wording. Have trended high temps
down for Thursday and Friday and they still may be too warm.

Long term Friday through Monday
Next cold front along with a sharp shortwave will cross the local
area Friday evening, the timing of which is better aligned between
the GFS ecmwf. Have carried precip chances across north-
central north-east oh NW pa into Friday evening night. With as
sharp as the trough is lake effect looks to be confined to Friday
night. High pressure and subsidence overspreads the area effectively
on Saturday and brings breaks to the mostly cloudy skies. That high
and the ridge aloft will shift east between Sunday and Monday.

Overnight lows will be at their lowest Saturday night especially if
we clear out with light winds. Will bring a number of locations
close to 40. Saturday will be the coolest day of the long term with
slowly moderating temperatures into early next week.

Aviation 18z Monday through Saturday
Vfr conditions with only cirrus will continue remainder of
today. Lake breeze will develop along the lakeshore from cle
east this afternoon.

Outlook... Non-vfr possible in patchy morning fog Tuesday
morning. Non-VFR possible Wednesday evening Thursday in
shra tsra with a cold front Wednesday evening. This will usher
in much cooler temperatures Thursday and flow off of the lake.

Non-vfr possible Friday with secondary front.

Marine
High pressure will linger over the region for one more day before a
cold front crosses the lake on Wednesday. Winds will remain
variable at under 10 knots till the front arrives. Winds will
become northerly behind the front but it now appears we will remain
below small craft criteria. Northerly winds will continue on
Thursday and then will briefly become southwest ahead of an
approaching cold front Thursday night. Winds will become northwest
behind the front on Friday. This time winds and waves may get large
enough for small craft consideration. Numerous showers and expected
Friday into the start of the weekend with some thunder and even
spout possible given the cold airmass. Winds will take on an
easterly component on Saturday which will dry things out.

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.
