AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
138 AM EDT Thu May 30 2024

.SYNOPSIS...
Upper level disturbances will keep a chance of showers through this
evening. High pressure will bring dry and cool conditions Thursday
through Friday. An unsettled pattern is expected from late Saturday
through early next week.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
Isolated showers continue into the early overnight hours on the
backside of an exiting low pressure system. Thunder potential
will be much more limited now after sunset, but cannot be
completely ruled out.

Shower coverage will continue to wane overnight, with little to
no coverage expected after midnight. Models show mid level
clouds dissolving overnight. Combined with the light surface
winds, this could result in patchy overland fog, with better fog
potential along river valleys.

Lows will be seasonably cool tonight, dipping into the 40s for
most.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM FRIDAY/...
High pressure from Canada builds southward through the Great Lakes
and Ohio Valley Thursday and Thursday night. High pressure should
provide a decent deal of sunshine on Thursday, but the air mass is
cool and below normal temperatures from the upper 60s to lower 70s
are expected. At night, decent radiational cooling with clear skies
and light winds will support lows in the mid to upper 40s.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
A series of disturbances and fronts will keep unsettled weather over
ILN through most of the period.

Departing high pressure should keep the weather dry Friday night.
Moisture returning behind the high ahead of a short wave will bring
the threat for showers and thunderstorms on Saturday and Sunday.
There may be a brief dry interlude early Monday before the next
short wave and a boundary arrive from the west with more
thunderstorm chances for Monday afternoon through Tuesday. A more
potent short wave and front colliding with an unstable airmass could
bring additional thunderstorms on Wednesday.

After a cool start Friday night with lows in the low 50s,
temperatures are forecast to be near normal through Tuesday with
highs in the upper 70s to low 80s, and lows in the low and mid 60s.
Warm advection may boost readings above normal to the mid and upper
80s on Wednesday.

&&

.AVIATION /06Z THURSDAY THROUGH MONDAY/...
Long wave mid level trof over the Eastern CONUS. Embedded
shortwave shifting south and east of the area. A few lingering
showers will continue to diminish as they track southeast for
the next couple of hours before dissipating. Due to isold
coverage and decreasing coverage have only have a VCSH mention
in the TAFs.

Mid level cloud deck will gradually erode tonight. This will lead
to river valley fog, which will impact KLUK. Also, expect MVFR
to IFR vsby restrictions at KILN. Vsby reductions will quickly
improve shortly after sunrise with VFR conditions thru the
remainder of the forecast. Some few to scattered cu development
will be possible this afternoon.

Winds remain below 10 kts through the period, shifting from the
NW to NNE this morning.

OUTLOOK...Thunderstorms will be possible late Saturday through
Monday.
