Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
Low pressure over far northwest ohio will continue to slowly
push eastward today. This low will move north of lake erie
tonight and reach the new england states by Sunday. A surface
trough will move across the area behind the low on Sunday. High
pressure will build southeast across the great lakes behind this
trough and settle over the region for Monday and Tuesday.

Near term through Sunday
Low pressure continues to creep slowly through the midwest and
is now over far northwestern ohio with a warm extending to the
east, now north of lake erie. Scattered residual showers and
isolated thunderstorms remain this morning across portions of
the forecast area but once this round of convection moves north
of the area, there will be a good period with minimal convection
this morning. As the low continues closer to the area and
daytime heating this afternoon, generally expect for convection
to fire back up with scattered showers and thunderstorms across
the area. Not expecting today to be a washout by any means but
just like Friday, everyone will see rain at some point and
several spots will get a couple rumbles of thunder. While there
isn't too much to key onto for today's convection, several of
the hi-res, near term guidance suggests an enhanced area of
convergence over NE ohio and NW pa, particularly as the low move
north of the area this afternoon. Therefore, have the highest
pops and QPF for this area.

With the loss of daytime heating and the forcing of the low,
convection should significantly diminish at sunset with some
residual showers lingering about NE ohio and NW pa. The next
round of rain will come on Sunday with a surface trough moving
across the area. This trough isn't all that strong so not sure
how robust convection will get going on Sunday... Thinking that
the best chances are east at this point, closer to the departing
low. Temperatures will be a bit cooler than normal as there is
plenty of rain and cloud cover to keep temperatures down.

Short term Sunday night through Tuesday night
Model differences continue in the short term period. The gfs
appears to be suffering from convective feedback so confidence is
pretty low today. A few showers are possible downwind of lake erie
on Sunday evening but those should be gone by early Monday. Monday
and Monday night will be quiet as high pressure passes to the north
resulting in dry easterly flow. Temperatures will average a little
below normal on Monday. Model differences really start to show up
on Tuesday. The GFS pushes showers and thunderstorms into the area
late Monday night as low pressure moves over the western lakes
forcing a warm front into the area. Just got a look at the new ecmwf
and it remains much slower with the main features and precip. Will
keep Tuesday morning dry and bring chances to the west third of the
area by 00z wed. Better chances for thunderstorms exist Tuesday
night. Temperatures Tuesday will get back a little above normal.

Long term Wednesday through Friday
It's going to get warm and humid by the end of the period. A weak
cold front will settle over the region on Wednesday. Scattered
showers and storms are likely as the front moves through. There will
not be a true airmass change behind the front and by early Thursday
the flow will be back to the SW and the warm up will begin.

Temperatures will push into the upper 80s some areas Thursday with
dew points around 70 degrees. Add a couple degrees to that for
Friday and expect some areas to add to their tally of 90 degree
days. Will keep both Thursday and Friday dry for now but certainly
cannot rule out a few pop up storms... Especially Friday.

Aviation 06z Saturday through Wednesday
Low pressure over indiana has extended a warm front north of
lake erie, allowing for the area to be in the warm sector. Some
scattered showers and isolated thunderstorms linger in the area
with one cluster in the region near ktol and kfdy and another
cluster in the vicinity of kcak. Have timed in precipitation to
ktol, kfdy, kcak, and kyng based on current radar trend.

Generally, the mixed bag ofVFR to ifr will lower across the
area to MVFR at the lakeshore areas with the downslope SE flow
at kcle and keri, but the remaining terminals will likely see
ifr at some point before dawn.

As for redevelopment of convection later today, the low is
slowly moving northeast and will be the primary forcing for
redevelopment. However, with the area in the warm sector could
see showers and thunderstorms develop pretty much anywhere. With
nothing to key on for precise timing but believe that all
terminals will see rain and non-vfr conditions at some point,
have a broad vicinity mention with prob30s for the best
thunderstorm chances. Winds will generally be light and
southerly for the first half of the TAF period ahead of the low
and as the low moves northeast of the area, winds will shift
around to the west. Keri will have some stronger
southerly southeasterly winds to start with gusts to 25 knots
possible over the next couple hours. Winds will relax at keri as
the flow shifts around to the southwest and then the west.

Outlook... Non-vfr conditions possible on Sunday in any showers
and thunderstorms.

Marine
East to southeast flow continues on the lake early this morning.

That should change this morning as low pressure along the in oh
border moves northeast to near detroit. A warm front from the low
will lift north of the lake by 18z with S to SW expected. Speeds
will generally be in the 10 to 15 knot range so will not need any
headlines. The low will linger over or just north of the lake
tonight into Sunday morning before finally moving off to the east
later in the day. A cold front trailing the low will push south by
late in the day causing the flow to become NW to n. Speeds again
should remain under 15 knots. By daybreak Monday the flow will be
ne as high pressure builds in from the north. The high will move
off to the east Monday night causing the flow to take on a southerly
component. Lot's of uncertainty exists in the models after that but
it appears another warm front will lift north across the lake late
Tuesday or Tuesday night with resulting southerly flow. This will
be followed by a weak cold front on Wednesday.
