AREA FORECAST DISCUSSION
National Weather Service Wilmington OH
650 AM EDT Tue Jun 25 2019

.SYNOPSIS...
High pressure will build into the area from the south. This will
result in a gradually warmer and more humid air mass as the week
progresses. A weak front will drop into the Great Lakes on 
Wednesday which could bring some scattered storms to parts of
the region.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Quiescent day across the region as high pressure builds in. Some
diurnal cumulus may develop, but there should be a good deal of
sun. Highs will reach the lower 80s area wide.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM WEDNESDAY/...
High pressure centered over the Tennessee Valley will extend
into the area through the period. This will lead to warmer and
more humid conditions by Wednesday. Convergence on a weak
westerly low level jet could develop a few showers across far
northern counties late tonight into Wednesday morning. Then a 
short wave will pass across the Great Lakes with an east-west 
front remaining north of the forecast area. The forcing may be 
enough in combination with diurnal heating to result in 
scattered storms in the afternoon, mainly in northern counties.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
A summertime pattern will be in place for the long term period with 
high temperatures in the upper 80s to around 90 Thursday through 
Saturday.  A few, primarily afternoon, thunderstorms will be 
possible during this time.  The best chance for the generally 
isolated thunderstorm activity will be across northern portions of 
the region.

On Sunday a frontal boundary will work down into the region allowing 
for slightly cooler conditions in the middle 80s and additional 
thunderstorm chances.  Monday will see continued high temperatures 
in the 80s with isolated diurnally driven thunderstorms.

&&

.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
VFR conditions are expected through the period. Few to 
scattered cumulus will develop with heating during the day and 
then dissipate towards 00Z. Some additional cumulus along with a
mid deck may push into the region late in the period. Winds 
will be southwesterly and increase to around 10 kt during the 
day. Winds will decrease and back to the south after 00Z. 

OUTLOOK...No significant weather is expected.
