.SYNOPSIS...
Issued at 1247 AM EDT Wed Jul 7 2021

Chances for showers and showers and storms continue into tonight
though the chance for severe weather wanes this evening. Another
chance for showers and storms exists Thursday especially south of
US-24. Then, Friday represents a brief reprieve from the
unsettled weather before the rain chances return this weekend.

&&

.SHORT TERM...(This Evening through Thursday)
Issued at 229 PM EDT Wed Jul 7 2021

A low pressure system pushes from Illinois into Southern Michigan
this afternoon into tonight. Out in the warm sector where our area
resides, showers and storms are expected to pop up and boundaries
like outflow boundaries or convergent boundaries could serve as foci
for them. Effective shear most conducive to sustaining severe
thunderstorms appears to reside north of the Toll Road today, but 15-
25 kts of effective shear does look to reside across the area. This
combined with 1000 to 2000 J/kg MLCAPE will allow for a chance for
mainly pop-up showers and storms this afternoon. Should the area of
DCAPE between 800 and 1100 J/kg line with where thunderstorms form
that would be conducive to damaging wind gusts. Some moisture is
located in the low levels, but PWATs are around seasonably
average for this time of year. With all of this in mind, some
storms could become strong to severe where the ingredients line up
nicely, leaving damaging from wet microbursts and locally heavy
rain as the main threats, especially if training storms occur.

Weak mid level lapse rates, waning CAPE and minimal flow should
allow thunderstorms to dissipate a couple hours after sunset
tonight. The still-humid airmass will continue to keep lows in the
mid 60s to around 70 degrees, cooler near the lake.

The front continues moving into the area during the overnight hours
and effectively removes the chance for heavier showers and storms
closer to the lake for Thursday and keeps those areas cooler than
the last few days. High temps near the lake may struggle to reach 80
degrees where northwest winds bring the cooler air in. A trough
pinwheeling in behind the front will help to set off a few more
showers and storms on Thursday. The speed that the front makes it
through the area will help to determine where the storms form, but
feel south of US-24 has the greatest chance to see a thunderstorm.
1000-2000 J/kg SBCAPE resides in that area and there is some DCAPE
to work with as well. Similar moisture content resides in the
soundings to today so could see more wet microbursts forming in that
area. South of the front, expect high temperatures to be cooler than
today, but still warm reaching the low to possibly mid 80s.

&&

.LONG TERM...(Thursday Night through Wednesday)
Issued at 229 PM EDT Wed Jul 7 2021

Height rises Thursday night signal a change to drier weather for
Friday as high pressure comes in. Highs only reach the upper 70s to
around 80 degrees with the cooler air around. However, this reprieve
is brief and rain enters back into the forecast Friday night and
Saturday as a clipper-like system, accompanied by a following high
pressure system and attached to the left exit region of the upper
jet, moves in. Following this system, another system deepens over IA
and IL and tracks into south-central Canada by Monday afternoon.
Models continue to advertise only weak to modest CAPE during this
period likely limiting coverage and severity of thunderstorms.
Increased moisture flux and above normal PWATs along with times of a
moist column and large scale lift will contribute to moderate
rainfall totals. Even still, models contain lacking consistency on
the clipper storm's track and when the most rain falls across the
area, Saturday or Sunday.

After that system tracks into Canada, the front associated with that
system moves through Tuesday, though again, without instability and
a much drier atmospheric column, really only a stray shower is
possible. Will restrict PoPs on both Tues and Wed to 30 percent at
most.

&&

.AVIATION...(For the 18Z TAFS through 18Z Thursday Afternoon)
Issued at 136 PM EDT Wed Jul 7 2021

Scattered convection is developing this afternoon and will
continue into the evening as weak ascent overspreads an
increasingly moist and unstable airmass. Brief gusty winds and
IFR/MVFR restrictions will be possible with any convection. A cold
front then works through or near KSBN by later tonight with low
stratus potentially building in. Some fog may also be possible at
both sites, but FWA ceilings should stay MVFR.
