Area Forecast Discussion
National Weather Service Cleveland OH
620 AM EDT Sat Jun 24 2017

.SYNOPSIS...
A trough of low pressure will remain across the Great Lakes
today and tonight. Sunday a cold front will swing east across
the region. Another cold front will move through on Monday
keeping temperatures below normal into mid week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Update...Will remove any mention of morning precip from the
east. Otherwise no significant changes.

Original...Radar shows showers in the east about to move out of
the area in the wake of a cold front now to our east. For today
models show a weak surface ridge building in from the central
plains while a second cold front/trough lingers east/west across
the central lakes. An upper low will be dropping southeast
across MN/WI. Increasing moisture is shown extending into nwrn
PA from the northwest during the afternoon and the HRRR shows
convection developing across the thumb of MI toward the area.
Will have partly cloudy skies for the day but will include a
slight chance pop for afternoon extreme north/northeast. Highs
in the upper 70s.

&&

.SHORT TERM /SUNDAY THROUGH TUESDAY NIGHT/...
The upper low moving through MN and WI today will move across
the central lakes on Sunday. A cold front associated with a
developing surface low in the same location will move across
the area during the day. The upper low will move east only to be
replaced by another dropping through the mean upper trough
which will persist across the area. This second upper low will
move through the area late Monday and Tuesday. Wednesday surface
high pressure from the plains will build across the Ohio Valley
as an upper ridge moves through. Will need low chance pops north
central/northeast on Sunday when the front moves through and
where moisture is best. Monday into early Tuesday the second
upper trough moves through with ample moisture for showers. Will
have high chance to likely pops in place. Wednesday should be a
dry day with building high pressure. Temps well below normal
Sunday through Tuesday.

&&

.LONG TERM /WEDNESDAY THROUGH FRIDAY/...
A ridge of high pressure over the area Wednesday into Wednesday
night will bring dry and seasonable conditions throughout the CWA.

By early Thursday morning a low will be moving eastward across the
far northern Great Lakes into Canada. This will bring a cold front
south across the area Thursday afternoon. This will mean a chance
for showers and thunderstorms. The front will stall somewhere in the
vicinity Friday, which will mean a continued chance for showers and
storms.

Warmer temperatures are in store for the middle and latter part of
next week with highs generally in the lower 80s.

&&

.AVIATION /06Z Saturday THROUGH Wednesday/...
Mostly clear skies are prevailing behind the cold front. A few
showers will continue to affect KYNG and KERI over the next two
hours or so before all precipitation chances come to an end.
Look for MVFR conditions in the rain, otherwise, expect VFR
conditions.

Cumulus will develop on Saturday with continuing VFR conditions.
Westerly winds will become a little gusty during the afternoon
hours.

OUTLOOK...Chance of brief MVFR in showers Sunday into Monday
with a cold front and trough aloft.

&&

.MARINE...
A westerly flow will continue across the lake through the weekend
and into early next week. Winds will increase a bit this afternoon,
but no Small Craft Advisory conditions are forecast. A cold front
will cross the lake Tuesday with a return to northwest flow. A ridge
will follow Tuesday night with the flow finally returning to a
southerly direction for Wednesday.

&&
