.SYNOPSIS...
High pressure will predominate into the middle of the week.
Temperatures will be on a warming trend. The chance of showers and
thunderstorms will return late in the week as a cold front slowly
approaches the area.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Surface high will continue to build southeast into the area through
the day. There may be enough low level moisture to allow just a few
cumulus to develop in the Tri-State. Otherwise, skies may be a little
milky as smoke aloft passes over the region. Highs will be in the
upper 60s to mid 70s.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/...
Surface high over the area tonight will slowly move southeast on
Monday. Meanwhile, mid level heights will rise as ridging works its
way westward. The atmosphere will be quite dry throughout the column.
Could still be dealing with some obscurations aloft from smoke. Good
radiational cooling conditions tonight will result in temperatures in
the mid 40s to lower 50s, but there will be a substantial rebound
with highs getting into the upper 70s to around 80.

&&

.LONG TERM /MONDAY NIGHT THROUGH SATURDAY/...
Expansive H5 ridge across a large portion of the central CONUS will
be the primary weather driver for the start of the work week. Ridge
axis will begin to align itself across the Midwest region by
Tuesday. The higher H5 heights will promote seasonably warm
temperatures across the Ohio Valley, with highs climbing into the
middle 80s. Broad area of surface high pressure will keep conditions
dry, but return flow will also be enhanced. This will lead to a
response in surface dewpoints on Tuesday as they begin to increase
to the middle 50s to near 60, making the air feel a little more
humid.

Wednesday is expected to be the warmest day of the week as highs
reach the middle 80s and perhaps a few locations hitting the 90
degree mark. More locations could reach 90 degrees if conditions
remain dry during the day. The ridge axis will begin to slide
eastward, with an elongated boundary stretching from the Great Lakes
down into the Ark-La-Tex region. This slow moving boundary will
eventually be responsible for an increase in shower and thunderstorm
activity late Wednesday, persisting into Thursday and Friday.
However, pcpn will likely be more focused along/NW of I-71 to start,
but as the boundary gradually pushes eastward, shower/storm chances
will migrate with it. Still uncertain on severe chances this far
out, and global models don`t paint a large QPF footprint in our CWA
with this particular system (especially near and south of the OH
River). This slow moving cold front may stall out just south of the
Ohio River on Friday, which could lead to continued chances for
scattered pcpn, especially in our southern counties. Daytime high
temps will return to near normal heading into the start of the
weekend.

&&

.AVIATION /08Z SUNDAY THROUGH THURSDAY/...
VFR will prevail through the period. A few cumulus could develop in
the Cincinnati area this afternoon. Otherwise just a bit of cirrus as
well as smoke aloft obscuring the sky, which is being reported in a
number of observations at a similar level as cirrus. Northwest winds
will increase to around 10 kt today and then become light and
variable tonight.

OUTLOOK...Thunderstorms are possible on Thursday.
