Synopsis
Multiple disturbances are expected to bring several rounds of
showers and thunderstorms to the region through the weekend and
into early Monday. High pressure and dry conditions are then
expected for Tuesday. More disturbances in northwesterly flow
aloft will cross the region later in the week.

Near term until 6 am Saturday morning
Apparent temperatures were expected to remain at or over 100 in
the southwest, which had me extend the current advisory into the
overnight hours as the eastern portion of it drops off later
today.

Upstream thunderstorm complex west of indianapolis and a shower
complex underneath the MCV northeast of indy will work into the
cwa later this afternoon into this evening. Expect convection to
be possible almost anywhere this evening but with a higher
propensity southwest of a richmond lebanon georgetown line.

Overnight should see convection from this evening waning, but
another upper level disturbance will ride southeast in the mean
flow and cross northern ohio. Storms from this will primarily
affect the i-70 corridor and northward, with isolated activity
possible elsewhere late overnight.

Confidence in the occurrence and or placement of these storm
clusters is low. Forecast will be dynamically updated as storms
fire and a better timing and areal extent of them are able to be
extrapolated in both time and space. With this being said,
forecast is probably too low on pops overnight in the northern
cwa where it was limited to chance category.

Short term 6 am Saturday morning through Saturday night
Saturday had me bring another tier of counties into the heat
advisory fold as unusually warm dewpoints solidly in the middle
70s combine with temperatures in the low 90s to push apparent
temperatures over the 100 degree mark.

Storms that are present in the morning should be focused north
of and along the i-70 corridor, but a few models are indicating
some isolated activity popping south of it just before daybreak.

The outflow boundary that lays out along the i-70 corridor later
in the day is expected to be a focus for a second round of
development, given an added boost by a continued feed of moist
and unstable air on southerly winds. Storms will fire along a
w-e oriented line and then move south in the evening.

Any storm in the next few days will have a higher potential for
damaging winds and especially very heavy rainfall. The tornado
and large hail threat appear to be negligible at this moment in
time.

Storms will weaken and diminish as they move south to the ohio
river on Saturday night. Dewpoints will remain in the middle 70s
until the airmass changes beyond the short term period.

Long term Sunday through Friday
A weak trof boundary is forecast to push through the region on
Sunday. This feature may be entering our far eastern southeast
zones by peak heating which would bring the highest pops to these
locations. All in all, just have slight chance chance of
showers storms. SPC has a slight risk for severe storms. There could
be an isolated severe during the afternoon due to diurnal heating.

For the period Sunday night into Monday night, mid level trough will
dig southeast across the great lakes eastern canada. As this occurs,
a cold front will move slowly southeast through our region. With the
lack of strong low level forcing and upper level support, the
chances for showers storms appears low and should affect our
eastern southern zones in the afternoon on Monday. Skies should
become at least partly cloudy Monday night as high pressure builds
into the region from the north with a drying and stabilizing air
mass.

High pressure should remain over the region through at least Tuesday
into Tuesday night with dry weather expected.

As the high moves east on Wednesday, return flow and increasing
moisture may lead to a small chance of showers and thunderstorms.

Models indicate that the next frontal boundary to affect our region
will be during the Thursday Friday time frame. Differences are seen
in the timing, so a broad brush forecast has been used with a chance
of showers and thunderstorms.

Temperatures will cool back down to more july normals Tuesday
through Friday.

Aviation 20z Friday through Wednesday
Vfr conditions will prevail over the CWA with the exception of
cmh lck where earlier rains and increased llvl moisture will
combine with light winds and a potentially clearing sky tonight
for fog development towards daybreak.

Models are indicating that a MCS will be passing north of the
cwa early Saturday tomorrow morning, with some showers affecting
all but cvg luk during this time. Positioning of the expected
rain and timing is in high question, and any low CIGS in central
ohio will be scoured out by storms when and if they occur.

Southwest winds will pick up tomorrow morning with gusts to 20kt
expected during the day.

Scattered convection is not out of the question for this late
afternoon and evening, but is not going to be forecast until the
potential source region becomes apparent.

Outlook... Thunderstorms will be possible at times through
Monday.
