Synopsis
The recent stretch of unseasonably chilly air will continue in
the region through thanksgiving day, with mainly dry conditions
expected through the end of the workweek. Slightly warmer
temperatures are anticipated this weekend, with rain likely
Friday night into early Saturday. Another system may begin to
impact the region towards the end of the upcoming weekend with
additional chances for precipitation.

Near term through tonight
An upper level disturbance rounding the base of deep broader-
scale troughing centered across the eastern third or so of the
country will provide a chance for a few flurries or perhaps even
brief periods of light snow through about mid-morning before
the best forcing lift exits to the east for the afternoon hours.

This being said, cannot completely rule out a few sprinkles
during the afternoon owing to steepening low level lapse rates
within a fairly moist bl. Dry conditions will return area-wide
toward nightfall, especially with surface ridging beginning to
nudge eastward into the western tennessee valley.

Amidst northwest surface flow and expansive cloud cover,
temperatures will once again top out well below seasonal norms,
with highs ranging from the mid 30s in the north to the upper
30s near and south of the ohio river.

Although daytime temperatures will remain relatively chilly by
autumn standards, do not expect temps to fall to much overnight
tonight as surface flow becomes more southwesterly ahead of the
weak front that will make its progression through the iln fa
during the day on Wednesday. With the pressure gradient staying
up a bit and lingering cloud cover, lows will bottom out only in
the mid to upper 20s by sunrise Wednesday.

Short term Wednesday
A weak front will make a quiet and rather unremarkable
progression through the iln fa during the day on Wednesday as
upper troughing digs into the northeast u.S. Midweek and beyond.

With continued and perhaps reinforced northwest flow aloft
locally, the recent stretch of unseasonably chilly days will
continue for Wednesday, especially considering that expansive
cloud cover will be sagging south from the great lakes into the
ohio valley during the day. This should keep temperatures in the
30s across central ohio to lower to possibly mid 40s further
south west in the tri-state area.

Long term Wednesday night through Monday
Mid and upper level ridging will shift east across the ohio valley
Thursday into Friday, providing for dry conditions. Highs on
thanksgiving day will range from the mid 30s in the north to the
lower 40s across the south. As the high shifts east of the area, we
will get into some WAA through the day on Friday with highs ranging
from the mid 40s north to the lower 50s in the south.

A progressive mid level short wave will move quickly east across the
region on Saturday. This will bring an increasing chance of rain
Friday night and continuing into the day on Saturday. Pcpn should
then taper off Saturday night with high pressure briefly building
into the area for Sunday. Highs both Saturday and Sunday will be in
the upper 40s to lower 50s. A stronger upper level trough low will
approach from the west Sunday night into Monday, leading to a chance
of rain showers to start the work week. Highs on Monday will be in
the low to mid 40s.

Aviation 12z Tuesday through Saturday
Banded very light snow flurry activity will be east of the
terminals by the start of the valid TAF period, with just a few
lingering flurries and or sprinkles possible throughout the
first part of the afternoon before the best lift forcing pulls
east of the local area.

Although some sites have actually goneVFR within the past
several hours, expect that MVFR ifr CIGS will filter back in
quickly this morning from the west. However, CIGS will begin to
lift improve by the afternoon, especially for western sites
where cloud cover will actually erode on the western periphery
late this afternoon into the evening period as the flow begins
to back a bit. A gradual trend to MVFR CIGS will be followed
several hours later by a scattering out of the clouds --
especially for western sites of kcvg, kluk, kday, and kiln.

There remains some model discrepancy in just how much low level
moisture will persist beneath the inversion for late this
evening into the overnight period for eastern sites of kcmh and
klck, although do think that these sites may not scatter out
quite as much before the arrival of more cloud cover from the
north toward 12z Wednesday.

Northwesterly winds of around 10-12kts this morning will go more
westerly and subside somewhat this afternoon as the pressure
gradient relaxes. Winds will go more southwesterly this evening
into the overnight period ahead of a weak front which will
progress through the area during the day on Wednesday. In the
prefrontal environment, winds will pick up past 06z and could
gust to 15-18kts or so for northern sites of kcmh, klck, and
kday by daybreak Wednesday.

Mid high level clouds will be on the increase from the north
late tonight, although most sites (except for kcmh and klck)
are expected to beVFR from 00z through the end of the period.

Outlook... MVFR ceilings possible Wednesday into Wednesday
night. MVFR ceilings and visibility possible Friday night into
Saturday.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
