.SYNOPSIS...
Mostly dry and cool conditions remain in place through the weekend.
More widespread rain chances return on Tuesday while below average
temperatures persist into next week.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
Band of clouds persists across the southern part of the forecast
area. These will decrease more through the night but probably not
completely dissipate. Forecast temperatures look reasonable.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...
High pressure continues to build in from the northwest Saturday
through Saturday night. Northwesterly/northerly flow keeps cool, dry
air over the Ohio Valley and temperatures remain below seasonal
averages for late May. Forecast highs on Saturday are in the 60s for
most locations under fair weather cumulus. Temperatures drop into
the 40s on Saturday night despite some lingering cloud cover
possibly remaining. A few locations east of Columbus have a chance
of dropping into the 30s if skies clear.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
The long term period will be characterized by below normal temps and
periodic chances for showers early to middle of next week, with the
overall potential for hazardous weather looking quite low during
this stretch.

For Sunday through early next week, the large-scale negative height
anomalies in the NE CONUS will stretch back to the W through the
Great Lakes as quasi-zonal flow becomes established from the mid MS
Rvr Vly through the srn OH Vly. Dry air will remain entrenched
across the local area through Sunday within continued NE LL flow,
even as a weak embedded system tracks through the srn OH Vly,
providing some increased cloud cover locally. As S/W energy pivots
to the SE from the upper Midwest into the south-central plains by
Monday, a weak sfc low should develop in response before slowly
migrating to the NE into the nrn TN Vly by Monday night. The
latitudinal placement of this low track will ultimately dictate
which areas remain dry and which ones will be susceptible to
episodic pcpn chances Monday night through Tuesday, with the latest
trends suggesting a slightly more well-defined system, which would
bring higher coverage of SHRA into parts of the ILN FA by Tuesday.

The subtle shift to a more well-defined system emerging into the OH
Vly for Tuesday of next week should effectively shunt the dry air
entrenched over the region this weekend off to the NE, allowing for
a return of rain chances late Monday through Tuesday, potentially
lingering in at least some fashion into midweek. The likely track of
the sfc low looks to be such that severe weather is not a big
concern locally at this juncture given the lack of instby and
disconnection from the richer LL moisture, but another bout of rain
should become increasingly likely by Tuesday as this slow-moving
system crawls NE through the region.

The overall large-scale pattern for midweek and beyond will likely
evolve into one or more closed/cutoff lows somewhere across the
upper Midwest into the Great Lakes, with negative height anomalies
favored to persist, as a whole, in the region through the entirety
of the long term period. This setup would most certainly keep the
below normal temps going through all of next workweek, and may even
keep periodic rain chances in the fcst into (and beyond) midweek
given the pattern. However, the details of this still remain
uncertain at these time ranges, but confidence is high in the
continued absence of above normal temps through the long term period.

&&

.AVIATION /02Z SATURDAY THROUGH WEDNESDAY/...
VFR will prevail through the period. High based cumulus will decrease
early in the period. Scattered cumulus will redevelop on Saturday.
Northwest to north winds will continue at 10 kt or less.

OUTLOOK...MVFR to IFR ceilings and visibilities are likely Tuesday
into Wednesday.

&&

.ILN WATCHES/WARNINGS/ADVISORIES...
OH...None.
KY...None.
IN...None.
