AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
244 AM EDT Sat Jun 1 2024

.SYNOPSIS...
High pressure of Canadian origin will bring dry and cool conditions
through this evening. An unsettled pattern is expected from late
Saturday through early next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
High pressure still remains in control tonight, but will
continue to trek eastward. Cirrus clouds spill in from the west
overnight ahead of the next system. While overnight lows will be
relatively cool once again, temperatures won`t drop quite as
much tonight. Temperatures will be mostly diurnal, but a late
increase in southeasterly winds may cause temperatures to
warm up a few degrees before daybreak on Saturday. Still, lows
will dip into the upper 40s to middle 50s across the CWA.

&&

.SHORT TERM /SUNDAY/...
Dry conditions are still expected to stick around Saturday morning
ahead of an approaching upper level vorticity max and weak surface
disturbance. Mostly dry conditions may actually end up persisting
across the area until afternoon when rain finally starts to move in
from the west associated with the aforementioned system. A severe
threat is not at all expected since instability is minimal and shear
is well below severe thresholds. Dew points and cloud cover increase
through the day on weak southerly flow. Forecast highs are near 80.

The chance for rain persists Saturday night with the upper level
trough axis pivoting through. Forecast QPF is less than and inch
with means there is little flood concern. Forecast lows drop into
the middle to lower 60s. Surface flow will be southerly to start the
night before shifting to the west later on the western side of the
trough axis.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Showers will still be ongoing at the start of the period as
weakening short wave continues east. But precipitation will
diminish as the day progresses. Any remaining surface boundary
will wash out and weak high pressure will build in resulting a
dry period from Sunday night through much of Monday night.

Mid level pattern will then evolve into a negatively tilted
omega block through the rest of the week. The region will be on
the troughing end of the block. This will bring chances of
showers and thunderstorms starting Tuesday. That will continue
into Thursday when the mid level trough becomes deep enough to
force a front through the region. Drier conditions are forecast
for Friday as high pressure builds in to the southwest.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
VFR conditions will continue tonight and thru the day light
hours Saturday as high pressure continues to slide off to the
east. High level clouds move across the region this morning,
with mid level clouds building in Saturday afternoon.

As a mid level shortwave and low pressure approach the area
the lower levels will saturate, with showers spreading across
the area late in the day into this evening. MVFR CIGs to develop
in rain showers with IFR conditions toward sunrise Sunday.

Surface winds around 5 kts will remain out of the southeast
overnight. Winds increase to around 10 kts on Saturday and will
shift toward the south.

OUTLOOK...Thunderstorms will be possible late Saturday through
Sunday, and again on Tuesday through Wednesday.
