.SYNOPSIS...
Broad area of high pressure will allow for dry conditions to continue
through mid week. A warming trend also continues until a slow moving
front approaches from the west, resulting in repeated rounds of
showers and storms through at least the end of the work week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Surface high slowly pulling east of the mid Ohio Valley, with surface
winds still light and mostly variable. As the high continues to pull
east and return flow develops, warmer daytime highs for today, even
through the upper level smokey skies.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM TUESDAY/...
Surface high pressure system will drift more towards the Atlantic
coast tonight, but still hold a strong influence across the Ohio
Valley. The new location of the surface high will result in enhanced
return flow tonight and on Tuesday, continuing the warming trend.
Overnight lows will be noticeably milder in the lower to middle 50s
-- nearly 10 degrees higher compared to the previous night.

Even with the modification in wind fields aloft, the HRRR smoke model
still suggests high concentrations of vertically integrated smoke
across our CWA on Tuesday. The difference, however, is that this
smoke is now being advected from the south (after previously
originating from Canada). This could potentially alter the
concentrations of smoke aloft and have it be more reduced than
models are suggesting. However, there will likely be some obstruction
aloft from the smoke, keeping a milky-white appearance in the sky
once again.

Daytime highs on Tuesday continue to trend warmer underneath the
amplified H5 ridge. Expect highs to breach the 80 degree mark for
the entire fa, trending more towards the middle 80s.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/...
Ridging at the surface and aloft centered along the south Atlantic
coast will continue to exert its influence across the region to
start the period. A short wave emerging out of the Ozarks will
deamplify as it rides up the back side of the mid level ridge into
the lower Great Lakes Wednesday into Wednesday night. Active
corridor of showers and thunderstorms will primarily stay west of
the area during this time frame, although could work its way into
west central Ohio.

The ridge gets suppressed later in the week as a more zonal pattern
sets up across much of the country. A cold front trailing low
pressure passing well north in Canada will end up laying out east-
west across the region. At this point, it seems most likely that
will be positioned across northern Indiana and northern Ohio. With
this boundary in the area, showers and thunderstorms will be
possible.

A robust short wave is forecast to move across the area Friday into
Friday night which will induce an area of low pressure that will
travel along the front. This will bring the greatest potential for
showers and storms. Once this passes, the front is forecast to sag
south of the area on Saturday, although it may start to return back
north on Sunday. This would bring a relatively dry period for
Saturday into Sunday morning with the possibility of precipitation
again by Sunday afternoon.

Above normal temperatures will occur, with lows being nearly 10
degrees above normal, until the low passes at the end of the week.
Temperatures will fall back over the weekend with readings closer to
normal.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
VFR prevails through the period, with the exception of KLUK which may
still have 08-12z MVFR to possibly IFR visibility restrictions with
lingering light wind in valley fog. Kept with persistence in SCT250
for high smoke. Not sold on adding HZ to TAFs with surface VSBY
restrictions over the past several days confined to MN and spotty
portions of IA, despite some forecast increase in near surface smoke
modeling from the HRRR. Will continue to monitor, but if any
restrictions do develop, would be higher level MVFR after 15z
Tuesday. Increasing SW winds also after 16z Tue.


OUTLOOK...Thunderstorms are possible on Thursday and Friday.
