12z aviation forecast update...

Synopsis
A cold front will move through the region this evening. A ridge
of high pressure will build southeast across the area Thursday
and Friday. Below average temperatures are expected for the end
of the week and weekend. Unsettled weather returns to the region
early next week.

Near term through Thursday
A MCV from an complex earlier in the night is currently moving
across our far northeastern areas this morning with scattered
showers and embedded isolated thunderstorms. This MCV will
continue to move eastward through the early morning hours. Most
of today will be fairly quiet compared to yesterday. The overall
mid level and upper level weather pattern begins to shift and
change today. An upper level trough develops over southern
ontario. This trough will support a cold front to push through
the region this evening and overnight. There will still be a
slight chance for a few scattered showers and isolated
thunderstorms this afternoon and evening but the severe weather
potential has shifted to the east coast. No strong or severe
convection is expected today across our local area.

The front will slowly move through the area late tonight.

Another wave of energy in the mid levels of the atmosphere will
ride along the front by tomorrow morning with a little better
chances for showers and isolated thunder. The front finally gets
the kick through the region on Thursday. Today will be the last
"warm" or above average temperature day for this week with highs
in the middle 80s. We will be at least 10 if not close to 15
degrees cooler on Thursday with the passage of the front and
scattered showers around.

Short term Thursday night through Saturday night
High pressure will slowly build south across the region with a cool
upper trough across the great lakes. Showers will slowly exit the
southern tier of counties Thursday night. Expecting dry conditions
beyond that, with some lake effect clouds Friday an or Saturday with
the northeast flow. Will keep precip chances under 15 percent and
have some partly cloudy skies. Definitely an airmass change. Highs
Friday and Saturday will be cooler in the low mid 70s and lows will
reach well into the 50s.

Long term Sunday through Tuesday
Models begin to diverge for the second half of the weekend and early
next week. Have blended guidance, but leaned it toward the ecmwf
which holds the weekend high pressure a bit longer and doesn't surge
moisture and precip northward with a lower mid mississippi valley
shortwave. With the uncertainty, returned to a dry forecast for
Sunday. Allow the return of moisture for Monday Tuesday along with a
gentle warming trend.

Aviation 12z Wednesday through Sunday
MainlyVFR conditions are expected through the next 24 to 30
hours with the exception for some light fog around tol through
14z possible. Some MVFR ceilings may linger for the next couple
hours through 14z or 15z for fdy, mfd, and eri... Have tempo
groups for this potential through mid morning. Cak and yng are
having some lower ceilings between 400 and 500 feet and have
carried tempo groups through 14z for these lower clouds which
will lift fairly quickly by mid morning. There could be a few
isolated storms this afternoon around the area but coverage and
potential for impacts are too low to mention in tafs at this
time. Generally winds will become westerly 5 to 8 knots today
and tonight.

Outlook... Intervals of non-vfr possible primarily with
scattered showers on Thursday.

Marine
A cold front will cross the lake tonight and slowly press south
across ohio on Thursday. High pressure across the northern great
lakes Thursday will shift to new england over the weekend. So for
lake erie, today's southwest flow will shift to the north-northeast
with the frontal passage tonight and generally remain from the
northeast through the first half of the weekend. Winds will be 15
knots or less with the exception of a period of time this
afternoon evening and again Saturday afternoon where winds will be
between 15 and 20 knots. During these periods waves will be choppy
and pushing 3 to 4 feet. Southerly flow returns for the weekend.

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.
