608 PM EDT TUE MAY 24 2016
High pressure over the region will continue to support fair
weather over the region through Wednesday. Warm moist air will
stream into the area for the later half of the work week. This
will produce some scattered showers and thunderstorms. Temperatures
will be above normal in the 80s.
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
High pressure will keep subsidence over the region tonight which
will support mostly clear skies and light winds. With the highest
dew points only in the lower 50s...low temperatures should drop well
down into the 50s for most of the cwa.
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH FRIDAY NIGHT/...
The airmass will see an slight increase in moisture which by early
afternoon could support some isolated showers and thunderstorms.
Looking at some cloud coverage by the afternoon which will hold
Temperatures in the lower 80s in most areas. The southwest breeze
will not be strong enough to suppress the lake breeze so look for
an afternoon cool down in the northeast lakeshore corridor.
Looking at an increase rain chances Wednesday night as a warm
front lifts into the area. The dynamics are weak and the
instability is modest, so could see more of scattered showers and
isolated thunder. For Thursday we are looking at the best dynamics
and instability for thunderstorms as an upper wave approaches.
Temperatures will remain above average through the period with
highs in the 80s.
.LONG TERM /SATURDAY THROUGH TUESDAY/...
A warm and humid airmass will get established over the area during
the period. Temps both Saturday and Sunday will climb well into the
80s. Unfortunately will need to continue with precip chances the
entire weekend. The models begin in decent agreement showing an
upper ridge across the Ohio Valley and Eastern Great Lakes. At the
surface...high pressure will be centered off the East Coast while
low pressure will be centered in the Plains. This ridge will slide
off to the east on Sunday and that is when the best chances for rain
will be. Monday will a little cooler and less humid so rain chances
will be more limited. Similar weather is expected for Tuesday.
.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
Mainly clear skies will continue through tonight with high and
mid level clouds moving in tomorrow morning in advance of the next
system. mainly sw flow expected during the period with light winds
tonight. given the pressure gradient the lake breeze may not make
it to KCLE today. Will however take the flow to wnw in a couple of
hours for a few hours.
Outlook...Short stretches of Non-VFR conditions possible in
showers and thunderstorms Wednesday night through Saturday as
well as early morning haze/fog/mist late in the week.
A light gradient will persist across the lake through the period
resulting in light winds and small waves. The best chance for
thunderstorms comes Wednesday night and Thursday as a weak back door
cold front drops onto the lake from the northeast while a
disturbance aloft moves through the region. Thunderstorm chances
will increase again over the weekend as a warm and humid airmass
settles over the region. Expect onshore flow to develop in the
nearshore waters each afternoon.
