area forecast discussion
national weather service cleveland oh
321 pm edt Tue oct 17 2017

Synopsis
Expansive area of high pressure will remain over the ohio valley
through Friday before shifting to the new england coast. An upper
level ridge strengthens aloft Thursday into Friday bringing
another stretch of warm and dry conditions to end the week.

Near term through Wednesday night
Quiet weather pattern continues through Wednesday night as high
pressure remains over the region. Only change of significance to
the forecast regards high temperatures on Wednesday. Bumped up
highs a few degrees from previous forecast, and a bit warmer
than a consensus blend of raw guidance. Highs today have
overachieved guidances by a degree or two, and expect the trend
to continue tomorrow, especially with continued waa, full sun
expected and 850mb-925mb temps a few degrees warmer than today.

Expect many areas to at least touch 70 degrees tomorrow. Kept
frost out of the forecast tonight, with outlying areas from
marion to mt. Vernon to wooster possibly dipping into the upper
30s again tonight. However, winds should be up enough to
preclude any widespread frost formation.

Short term Thursday through Saturday
High pressure will be located over the southern appalachians on
Thursday as a weak cold front approaches lake erie from the
north. It appears the front will stall north of the lake. High
pressure then moves back into the area at the surface and aloft
by Friday and persists into Saturday.

Above normal temperatures will continue through the short term
period with highs into the 70s. The warmest day of the short term
will be Saturday with highs at many locations touching the middle
70's.

Long term Saturday night through Tuesday
The long term will bring changes to the area, ending the stretch of
fair weather with a sweeping cold front early next week. Strong jet
energy off of the pacific northwest will translate across the
country and dig a trough across the great lakes and northeast into
mid week. The current cold front timing takes it across the local
area on Monday. Have increased precip chances above blended guidance
with a good tap of gulf moisture, but timing may still be an issue.

Will likely see fluctuation in timing as there is some indication of
a split flow possibility. For temperatures took a blend of guidance
which takes us from lower 70s Sunday down to upper 50s around 60 for
Tuesday. With the trough, cooler air, and flow off of the lake, have
precip chances continuing into Tuesday.

Aviation 18z Tuesday through Sunday
Vfr conditions will continue through the TAF cycle with high
pressure over the ohio valley. Gusty southwest winds this
afternoon to 20 knots will subside a bit overnight, with winds
in the 5-10 knot range.

Outlook... Non-vfr in morning fog for inland locations possible
early Friday morning.

Marine
Southwesterly winds will remain in the 15 to 25 knot range into the
night with waves greater then 4 feet for the eastern half of the
lake. Water levels across the western basin continue to drop and are
very close to reaching levels that are low enough to impact
shipping. Will watch this very closely and issue a low water
statement if needed. Winds will decrease this evening into the
overnight so the water levels should rise shortly. Another weakening
cold front will sag toward the lake from central ontario on Thursday
with the pressure gradient tightening. This will once again increase
the southwesterly winds with a small craft advisory possible for the
east half of the lake. High pressure increases its influence on
Friday with light winds expected.

Cle watches warnings advisories
Oh... None.

Pa... None.

Marine... Small craft advisory until 4 am edt Wednesday for lez145>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.
