AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
755 PM EDT Tue Jun 18 2019
.SYNOPSIS...
A stalled frontal boundary draped across Ohio and Indiana will
continue to produce more showers and thunderstorms into this
evening. Some of the storms could produce heavy rain and the
flooding threat will continue. Activity will be on the decrease
tonight before strengthening low pressure approaches the area
late Wednesday and Thursday, bringing more showers and thunderstorms
to the area. After a break on Friday, more active weather is
expected over the weekend.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
Scattered showers and isolated thunderstorms will gradually
dissipate through the evening. With the ground already
saturated, any locally heavier rain that may still occur this
evening could cause flood issues.
Expect the clouds will decrease as well, at least temporarily.
But it appears that a lower deck will develop late tonight. Lows
will drop into the mid 60s area wide.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
We should continue to see a relative lull in convective coverage
Wednesday morning -- of course given the high vulnerability any
heavier shower could cause renewed high water issues.
A noticeable increase in convection is then expected starting
Wednesday afternoon as an upper trough approaches from the
west. Environment will be the same characterized by high
moisture and some instability. Low level jet will allow promote
more shear, particularly during the evening and overnight hours.
So, expect high PoPs to continue into the night.
Potential hazards will include both flash flooding and severe weather.
Given collaboration with neighboring offices, a continuation of
the the flash flood risk prompts an extension of the Flash Flood
Watch. For severe, the primary risk appears to be damaging wind
gusts, particularly later Wednesday and into the night given
better shear and potential for organized convection.
&&
.LONG TERM /THURSDAY THROUGH TUESDAY/...
An unsettled weather pattern will be present through most of the
long term time frame. Thunderstorms are in the forecast every day
except for during the day on Friday. With the repeated rounds of
showers and thunderstorms, there will be the potential for
additional flooding concerns. Will continue to highlight this
threat in the HWO.
There will be the potential for severe weather at the start of the
long term on Thursday and then again over the weekend as well. Will
continue to highlight the severe threat on Thursday in the HWO. Will
hold off on the weekend systems until there is more confidence in
the location of the severe weather potential.
High temperatures will increase from Thursday until Sunday and then
be just slightly cooler on Monday.
&&
.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
There is a low chance of remaining convection affecting the
terminals in the first few hours of the period. Otherwise it
will be VFR to start. Most indications are that an IFR deck will
develop after 08z with some lower visibilities possible as well.
At this point only have moderate confidence in this occurrence.
clouds will lift to MVFR during the morning and eventually
become VFR by 18Z. There may be some additional convection in
the latter part of the period, but chance of affecting any
particular terminal seemed low enough that far out in time to
not include any mention in the TAFs at this point.
OUTLOOK...Thunderstorms will be possible through Thursday, and
again Friday night through Sunday.
