Synopsis
A couple of upper level disturbances will keep off and on shower
activity through Friday. High pressure will allow for dry
conditions most of Saturday and Sunday. Another system will
bring a return of precipitation to the area Sunday night into
Monday.

Near term until 6 am Friday morning
A PV anomaly will be working through the region this afternoon
allowing for scattered shower activity. There is some limited
instability and cannot rule out isolated thunder. The small hail
potential will continue until the early evening hours due to
very low freezing levels. A few wind gusts will be possible,
however winds in the low levels are pretty weak and therefore
expect this activity to be isolated.

Precipitation activity will decrease in activity during the
overnight hours, however some rain and snow showers will be
possible. The greatest chance will be across central ohio.

Went close to the blend for temperatures during the overnight
hours with lows in the 30s.

Short term 6 am Friday morning through Friday night
As another disturbance works through on Friday expect some rain
and snow showers to continue, gradually transitioning to rain
showers. This activity will come to an end Friday evening.

Low level flow increases on Friday with gusty winds expected.

Some wind gusts of 30 to 40 mph will be possible, with the
highest wind gusts expected across central ohio.

Went close to the blend for temperatures again Friday and Friday
night with highs on Friday in the 40s and lows Friday night in
the 20s.

High pressure will begin to work into the region Friday night
and winds will begin to decrease.

Long term Saturday through Thursday
Surface high pressure will be in place across the region on
Saturday, providing for dry conditions and slightly below normal
temperatures. Highs on Saturday will range from the mid 40s in the
north to around 50 across the south. The high will shift off to the
east Saturday night into Sunday with some return flow developing on
the backside of the high. This will lead to an increase in clouds
through the day on Sunday along with warming temperatures with highs
ranging from the mid 50s north to around 60 degrees in the south.

The 12z models have come into better agreement with the surface
low wave that will move across the ohio and tennessee valleys Sunday
night through Monday. This will lead to an increasing chance of
showers from the west Sunday evening and will allow for likely pops
later Sunday night and into early Monday. Colder air will filter
down across the area on the backside of the low later Monday into
Monday night. The models are in decent agreement drying things out
though before any of the pcpn should change over to snow. Will
therefore just allow for a decreasing chance of rain showers from
the northwest Monday afternoon into early Monday evening. Highs on
Monday will range from the lower 40s in the north to the lower 50s
across the south.

Surface high pressure and dry conditions will build back down into
the region Tuesday into Wednesday. Highs on Tuesday will be in the
40s, warming to highs in the upper 40s to mid 50s for Wednesday.

Aviation 20z Thursday through Tuesday
Scattered shower activity will continue through the afternoon
before decreasing this evening. Cannot rule out isolated
thunder, however due to the isolated nature decided to leave out
of the tafs at this time. Vsbys may be reduced briefly with the
shower activity. Although a brief wind gust is possible, due to
the weak low level flow left out of the tafs for this afternoon.

Some lighter more isolated shower activity will work into the
area late tonight and into the morning on Friday. Handled this
with a vcsh at some of the TAF sites. Winds will pick up on
Friday with wind gusts around 25 to 30 knots possible.

Although CIGS will beVFR at times and potentially ifr at times,
expect predominately MVFR CIGS for the TAF period.

Outlook... Gusty northwest winds 25 to 30 knots possible on
Friday afternoon. MVFR CIGS are possible Sunday night and
Monday.

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.
