Synopsis
Building high pressure and a continued feed of warm and humid air
on southerly flow will be the rule of the weather through
Saturday. A surface boundary will slowly cross from the
southern great lakes at daybreak Sunday to south of the ohio
river by daybreak Monday, providing a focus for the next round
of showers and thunderstorms in the region.

Near term until 6 am Friday morning
Southerly winds 5-10 mph will keep temperatures from falling
past the mid 70s tonight, setting the stage for a hot one on
Friday.

Cloud cover over eastern half of the CWA will dissipate quickly
this evening in favor of generally clear skies overnight.

The wind and warmer air will limit any morning fog to the cooler
river valleys where winds have a better chance to decouple and
temperatures will meet dewpoints in the lower 70s.

Short term 6 am Friday morning through Friday night
Continued excessive heat warning through the short term time
period. Ridge will build more into place for Friday and
therefore expect less in the way of thunderstorm activity and
cloud cover. In general expect mainly just some CU with an
isolated thunderstorm possible across central ohio during the
afternoon. With more sunshine expect temperatures to climb into
the low to middle 90s areawide. Dewpoints will be in the middle
70s. This will allow dangerous heat index values between 105 to
110 across many locations.

There will be very little relief from the heat Friday night as
lows will only drop into the middle to upper 70s. Dry conditions
are expected through the overnight hours Friday night.

Long term Saturday through Thursday
Upper ridge will remain over the region on Saturday, keeping the hot
and humid airmass locked in. High temperatures once again will be in
the mid 90s and dewpoints in the mid 70s, producing heat indices 105-
110. Excessive heat warning is already out covering this. Tossed out
the GFS qpf Saturday and leaned towards the dry ecmwf.

The h5 ridge begins to break down Sunday as a backdoor cold front
drops into the region. Scattered thunderstorms are forecast with the
advancing front. The heat and humidity will begin to lower on Sunday
as the pcpn and clouds will keep highs in the upper 80s to lower
90s. Heat indices will be 100-105 so will add it to the hwo.

The front will be exiting the region Monday morning, but lingering
lift across the region could produce some scattered convection.

Highs on Monday will be down into the mid 80s.

By Tuesday, high pressure centered over the great plains will be
bringing less humid air into the region. Highs will be in the lower
80s. High pressure will continue to sink into the region Wednesday
into Thursday, keeping the more comfortable airmass situated over
the region.

Aviation 00z Friday through Tuesday
South winds will persist overnight in the 5-10kt range, highest
in the west. Cloud cover from iln eastward will dissipate
relatively quickly this evening as the warm advection through
the atmosphere cuts into them from the southwest.

Fair wx CU is expected tomorrow but a continued feed of warm air
will generally keep them scattered in nature. A few models are
pointing at a threat of a shower in central ohio that has a
potential to affect cmh lck TAF sites tomorrow afternoon. This
is a low probability <20% and will be driven by daytime heating.

Outlook... Thunderstorms possible Sunday.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
