Special Weather Statement, NWS Cleveland, OH

Area Forecast Discussion
National Weather Service Cleveland OH
1058 PM EDT FRI JUL 8 2016

.SYNOPSIS...
Low pressure over the northern Great Lakes will continue east
tonight. A cold front trailing the low will move across the local
area tonight. A secondary cold front will follow on Saturday. High
pressure will build southeast out of Canada on Sunday and move
east of the area by Tuesday.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
The air mass is stabilizing except over Lake Erie and with limited
low level convergence do not expect the activity to get bigger
except perhaps along the east lakeshore and a few other rogue
storms. Some of the storms will persist on their own momentum and
outflow boundaries but they should slowly dissipate during the
early morning hours as the front weakens. Made minor adjustments
to the hourly temperatures and dew points to account for areas
where it has rained. No other significant changes for the
overnight forecast.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH MONDAY NIGHT/...
A secondary cold front will drop south across the area on
Saturday. There will finally be an airmass change behind this
feature with dewpoints eventually dropping back into the 50s.
There will be a good 4 to 5 degrees of cold air advection at 850
mb behind this front so think guidance highs tomorrow may be a
little high. Expect some instability showers for a few hours
during the middle part of the day. Best chances will again be east
of CLE. After that high pressure will dominate through the end of
the period. Do not expect any warming till at least Monday while
the surface ridge finally moves off to the east. Have trended
toward the cool side of guidance for temps.

&&

.LONG TERM /TUESDAY THROUGH FRIDAY/...
The models continue to differ some on tue on whether moisture can
return to the area quick enough for possible convection to develop.
Will keep pops to slight chc or less. A daily threat for convection
seems reasonable wed thru fri as a moist and humid airmass should be
present while a weak cold front tries to push across the area by fri.

Temps will run above normal tue thru thu but fri is more
questionable doe to the uncertainty of the progress of the weak cold
front.

&&

.AVIATION /00Z Saturday THROUGH Wednesday/...
A broken line of showers and thunderstorms precede a cold front
across southeast lower MI and northwest OH. Southern extent of the
line is struggling. The better dynamics are located the further
north you go. Potential still there that a storm gust could reach
50s knots. Will amend if confidence increases for any specific
terminal. Current cumulus field not looking like it will produce
any shra/ts so we will have to wait for that line to our west.
Therefore removed the earlier mention of TS and narrowed the
timing. For those areas where the confidence is
higher...TOL/CLE/ERI have put in TEMPOs. Temporary IFR in the
heaviest downpours. Looking for thunderstorm impact to be around
2Z to 3Z for CLE and 3Z to 5Z for ERI.

Still agree with the previous forecast of areas of mvfr fog
developing late tonight and transitioning to mvfr cigs for a good
part of sat morning into early afternoon. Additional sct shra and
a few possible tsra are likely to develop over ne oh and nw pa
with daytime heating on sat.

Winds will turn to the northwest with the passage of the front and
have minor gusts to 20 knots for Saturday.

Outlook...Areas of non-VFR possible late Saturday afternoon and
evening with sct shra/tsra in NE Ohio/NW PA. Areas of non vfr
possible again by wed.

&&

.MARINE...
Low pressure moving east of the lakes tonight will pull a cold front
across lake erie. SW winds will veer to the west then nw while winds
increase to 15 to 20 knots by daybreak. Marginal sca waves may
develop for the east half of the lake for sat. Winds will gradually
diminish sat night thru sun as high pressure moves over the lake.

Light winds will turn out of the south mon thru wed and increase to
about 10 to 15 knots as the highs shift off to the se and a weak
cold front starts to approach from the nw by late wed.

OH...None.
PA...None.
MARINE...None.
