AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
1033 PM EDT Mon Jun 17 2019

.SYNOPSIS...
An oscillating frontal boundary in the region will provide daily
chances for showers and thunderstorms through Thursday
afternoon with a brief dry period possible Thursday night into
Friday. Additional rounds of showers and storms are possible
this weekend, with seasonable temperatures and very humid
conditions persisting through the foreseeable future.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
This evening's MCS will move east of the forecast area by
midnight. Then expect a lull in activity, but it appears that 
another impulse will lift northeast into the area before 
daybreak bringing a return of showers and some storms. Very 
minor adjustments to temperatures based on latest trends.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
Region remains in the same moist unstable airmass on Tuesday.
Convection will redevelop as heating of the day takes place.
Best coverage is expected southeast of I-71 as the front shifts
south with time. Highs on Tuesday will be in the upper 70s.

Convection will be gradually shunted eastward Tuesday night as
a weak high pressure system pushes slightly drier air into the
region.

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
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.  Although widespread severe weather is not 
expected, there will be the potential for at least isolated damaging 
winds with the thunderstorm chances.

High temperatures will in the 70s and 80s through the long term. Low 
temperatures most nights will generally be in the 60s.

&&

.AVIATION /03Z TUESDAY THROUGH SATURDAY/...
MVFR to IFR ceilings will develop overnight. Additional showers
will also lift northeast across the region late tonight into 
Tuesday morning. Ceilings will slowly lift with conditions 
returning to VFR before the end of the period. There is the 
potential for more storms Tuesday afternoon, but there is too 
much uncertainty to include in the TAFs this far out in time. 

OUTLOOK...Thunderstorms will be possible through Thursday.
