Synopsis
Weak disturbances in the upper flow will bring a chance of
thunderstorms to northern ohio today. A cold front will bring
more organized showers and thunderstorms on Tuesday, then drier
and cooler air moves in for the rest of the week.

Near term until 6 pm this evening
Latest runs of the models continue to suggest that vort maxs in
the zonal h5 flow will act as the catalyst for convection
across NRN in oh this afternoon. Tweaked the onset of the timing
by an hour here or there, but still left the best pop chances
across west central ohio with lesser chances as you head south.

Cloud develop today could hinder the eclipse viewing, but right
now don't expect a thick overcast deck.

Adjusted the temperatures down a degree or two due to the
eclipse and adjusted the hourly temperature trace.

Short term 6 pm this evening through 6 pm Tuesday
This evening, convection or decaying showers from the afternoon
will start to come to an end as daytime heating is lost. Tonight
a potent upper level system over the hudson bay will begin to
wrap up into an upper level low and head south. Mid and upper
level flow will quickly start to amplify as the newly formed low
pushes southeast.

Ahead of the main upper level system a wedge of PV will swing
east helping to get showers and thunderstorms going Tuesday
afternoon. Sfc to 6 km bulk shear values at this time are around
40 kts (slightly higher on the NAM and slightly lower on the
gfs). Ml CAPE values on the GFS are only around 700 j kg while
the NAM has values approaching 2000 j kg. Looking more in depth
at forecast soundings reveals why. The GFS clearly shows a
cirrus shield inhibiting the area from fully destabilizing. Also
at this time the cold front has yet to enter our cwa. Therefore
convection will be dependent on destabilization as surface
convergence from the front will come later. Not surprisingly spc
has therefore kept the area in a slight risk given supportive
bulk shear vectors and questionable instability. The primary
threat still looks to be damaging winds (possibly some type of
broken line forming).

Long term Tuesday night through Sunday
Showers and thunderstorms will linger into Tuesday evening,
especially across southeast portions of our forecast area. However,
as the cold front pushes off to our southeast and drier air begins
to filter in behind the front, expect pcpn to taper off from the
northwest as we head into Tuesday night.

Surface high pressure will build down across the great lakes through
the rest of the week. This will lead to mainly dry and cooler
conditions. However, some mid and upper level short wave energy
dropping down across the great lakes on Thursday could lead to a few
showers, especially across northeast portions of our area.

Temperatures through the end of the week will be several degrees
below normal with highs in the 70s and overnight lows in the 50s. We
will start to get into some return flow through the weekend, leading
to a slight warmup by the end of the long term period.

Aviation 15z Monday through Friday
Convection has fallen apart as it has moved into the area this
morning with only some lingering low CIGS at kluk. This
afternoon high res models then indicate showers and
thunderstorms possibly forming across our northwestern zones
along the nose of a weak llj. The rap, hrrr, WRF dart, and nmm
show convection in some form or fashion while the nssl WRF and
nam 3 km are dry. For now have just added a vcsh for kday due to
uncertainty in formation.

Tuesday morning into afternoon more showers and thunderstorms
will be possible ahead of an approaching cold front.

Outlook... Thunderstorms are likely Tuesday into Tuesday
evening.

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.
