Showers and a few thunderstorms will be possible through
tonight as a low pressure system moves through the ohio valley.

A cold front will push east across the area on Friday with a
drier, cooler air mass moving into the region behind it. Another
low pressure system will bring additional rain chances to the
area later Saturday afternoon into Saturday night.

Near term until 6 am Friday morning
A warm front is pushing north into our area this afternoon and
currently looks to be up to about the ohio river. To the north
of this, we are continuing to see some occasional rain showers
persist across much of our northern fa.

Mid level energy moving out of the mid mississippi valley will
help a developing surface low pressure system lift northeast
across the ohio valley through tonight. This will be accompanied
by a strengthening 40 knot low level jet that will rotate up
across our area through this evening overnight. This will allow
for the shower activity to become more widespread as we head
into this evening and tonight. Some weak instabilities will
also be in place across the area into tonight so will continue
with a mention of some embedded thunderstorms, mainly into this
evening. As the low lifts northeast across the area, a trailing
cold front will push in from the northwest late tonight with
perhaps a decreasing trend in pcpn coverage across our far west

The NAM cmc and several of the 12z higher res models are
suggesting some heavier rain swaths with some localized amounts
of 2 to 3 inches possible. The GFS and the ECMWF are not as
aggressive, with the ECMWF keeping the heaviest swath to our
northwest. FFG is on the higher side with 6 hour guidance
generally in the 2 to 2.5 inch range. Considered going with a
flood watch across parts of our northwest to account for this.

However, with some uncertainty between the models in the
location of the heaviest swaths and the latest rap and hrrr
continuing to shift farther to the northwest, have opted to hold
off on a watch. That being said, think there is potential to see
a fair amount of flood advisory type issues tonight and will
continue to mention this threat in the hwo.

Short term 6 am Friday morning through Friday night
The mid upper level trough axis will shift off to the east
through the day on Friday with the surface low shifting off to
our northeast and the cold front moving east of our area. This
will lead to a decreasing trend in pcpn from west to east as we
progress through the day. As drier air moves in, we will also
see at least some partial clearing work in from the west through
the afternoon. In developing low level CAA behind the front,
winds will be on the increase and become gusty. Have trended a
little closer to the more mixy gfs, with wind gusts in the 30 to
35 mph range possible. Highs on Friday will be in the upper 50s
to lower 60s.

Mainly clear skies are expected for Friday night with lows
ranging from the upper 30s in the north to the lower 40s in the
south. It does look like the gradient will help keep the winds
up enough through the night to limit any frost development
across the north Friday night.

Long term Saturday through Thursday
An unsettled weather pattern will be in place for this weekend and
into next week with multiple systems moving through the region.

Although dry conditions will start out the day on Saturday an
approaching low pressure system will bring precipitation chances to
the region beginning during the afternoon hours on Saturday.

Precipitation will taper off Sunday morning. Instability is limited
during this time and therefore generally kept any thunder mention
out of this time period or at a minimum.

Clouds will decrease for Sunday evening into the first part of
Sunday night. There is the potential for some frost across central
ohio if winds decrease for a long enough period of time. At time
point limited frost mention to central ohio and kept it patchy.

The dry weather for Sunday night will be short lived as
precipitation chances move back into the region for Monday and
remain in place through the week. Warmer temperatures will be in
place during this time with highs generally in the 60s in 70s. A
few 80 degree temperatures will also be possible near and south of
the ohio river on Wednesday and Thursday. There is at least some
instability each day and therefore have a thunder mention in the
forecast as well.

Aviation 00z Friday through Tuesday
Flight conditions will be affected by weather associated with
low pressure moving from central indiana to northwest ohio.

Showers and thunderstorms will be accompanied by ifr
visibilities, and wind gusts as high as 35 knots this evening at
cvg and luk. Thunderstorms may decrease in strength overnight,
while showers increase in coverage, and MVFR ceilings become

As the low lifts north on Friday, winds from the northwest will
increase in speed with gusts over 30 knots.VFR should arrive
Friday afternoon as high pressure moves closer, while wind
speeds gradually subside by Friday evening.

Outlook... MVFR conditions will be possible on Saturday night
into Sunday morning.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
