Area Forecast Discussion
National Weather Service Wilmington OH
1055 AM EDT Fri Jun 22 2018
.SYNOPSIS...
Showers and thunderstorms will continue to develop today through
Saturday as low pressure moves slowly from Illinois across Indiana
to Northern Ohio. Showers and thunderstorms will be possible
again on Sunday when a disturbance is forecast to cross
Kentucky. High pressure centered over New England will provide
dry weather Monday and Tuesday.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Low pressure was located near the IL/IN border late this
morning, with several areas of showers rotating around the low.
KILN WSR-88D already indicates a few showers across the
northern portion of the CWA at 14Z (lifting northward), and a
band of showers/thunderstorms not too far from the Tri-State
across southern IN/central KY (moving northeast).
Guidance is in good agreement with the big picture, where the
coverage of showers and thunderstorms increases through the
midday and afternoon hours east of the low. Multiple
bands/rounds of showers and thunderstorms are expected to rotate
to the northeast/north through CWA through the evening hours.
Thus have PoPs ramping up to likely across the CWA by afternoon.
12Z/22 Jun KILN RAOB shows the precipitable water value has
actually decreased a little since yesterday. Still, other
sources indicate there's plenty of moisture in the atmosphere
and convection will be capable of producing heavy rainfall in a
short period of time. The most vulnerable area, which has
received some heavy rainfall in recent days, appears to be from
east-central Ohio including Hocking County west-northwestward
through central Ohio and the northern Miami Valley. Therefore,
will issue a Flash Flood Watch through this evening for these
areas. Further south, vulnerable areas are more localized and
thus will not extend the Watch further south, but certainly even
in the non-Watch area localized flash flooding is possible in
any heavy rainfall that occurs in a short period of time.
Considering the severe threat, there will be some instability,
most likely highest CAPE residing across the southern portion of
the CWA. Wind shear is not particularly strong, which may hinder
severe potential. But considering the high moisture/sufficient
instability environment, a few storms may have the potential to
produce strong to locally damaging wind gusts.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
Low pressure will be lifting from Indiana tonight to Northern
Ohio on Saturday. With the ILN area in the zone of favorable
lift and moisture advection ahead of the low, showers and
thunderstorms will continue to be likely tonight. Precipitation
should exhibit a diminishing trend from south to north on
Saturday when the low is forecast to be near Lake Erie. Lows in
the mid 60s will be followed by highs in the upper 70s on
Saturday.
&&
.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Low pressure tracking slowly through the Great Lakes will keep a
chance of showers/thunderstorms in the forecast Saturday night. This
chance will linger into Sunday mid level s/w drops through the Great
LAkes and an associated sfc front drops south into the TN VLY. The
best chance will occur across ILN/s southern counties. Sundays
temperatures look to be close to normal with high generally in the
lower 80s.
Mid level ridging and surface high pressure to build across the area
early next week offering dry weather. Expect highs Monday to range
from 80 north to 85 south with readings a few degrees warmer
Tuesday.
Mid level s/w to track through the Great Lakes at mid week with
associated warm front providing a good chance for showers and
thunderstorms Wednesday. Warm temperatures forecast for Wednesday
with highs in the mid and upper 80s.
Mid level ridge to build to our west with the numerical models
pointing toward the potential for ridge riding storms in the
northwest flow around the periphery of this ridge next Thursday.
Very warm temperatures for the end of next week with highs Thursday
in the upper 80s to around 90.
&&
.AVIATION /14Z FRIDAY THROUGH TUESDAY/...
Aviation will continue to be affected by a slow moving low
pressure system. Ceilings as low as LIFR have developed in the
nearly saturated circulation around the low. Conditions will be
improving to MVFR and VFR through mid morning under modest
mixing.
Thunderstorms will be developing by this afternoon in the
unstable airmass, with ample forcing provided by the well
stacked low pressure system. Kept afternoon conditions VFR for
now, with later forecasts pinpointing lower ceilings and
visibilities closer to occurrence. MVFR ceilings are forecast
to redevelop near the end of the forecast. Winds out of the
south will stay around 10 knots or less, shifting to southwest
at CVG near the end of their 30 hour TAF.
OUTLOOK...Showers and thunderstorms possible at times through Sunday.
