Synopsis
A ridge of high pressure will build east across the great lakes
through Wednesday night. A low pressure system will move east
out of missouri to lake erie by Friday and to the delaware coast
by Saturday morning. Another ridge of high pressure will build
east across the area Sunday and to the east coast by Monday.

Another area of low pressure will move east across the ohio
valley Monday night into Tuesday.

Near term /through Wednesday/
Minor adjustments to hourly temperature and sky cover trends,
otherwise no major changes to the forecast with this update.

Held on to cloud cover a little longer. Latest satellite shows
clearing line down to near kdtx. Expect the clearing trend from
north to south to be slow tonight, especially across the eastern
half of the area with low clouds lingering a bit further
upstream.

Original discussion...

low pressure continues to move east away from the area at the
surface. Rain associated with the low is also well east of the
area as well. High pressure will continue to build into the
local area tonight allowing low clouds to gradually decrease in
areal coverage. Latest satellite imagery shows some breaks in
the lower cloud deck allowing Sun to penetrate to the surface
over the lake. This is a result of drier air in the lower levels
to push south into the region. Some cold air advection will
take place causing temperatures to drop into the lower to middle
30s.

Short term /Wednesday night through Friday night/
Models are still struggling to come into agreement over the next
few days. The GFS is still the most aggressive with the moisture
and timing of the precipitation over the last several runs. The
gfs brings the precipitation well into the area during the day
Thursday while the rest of the models hold off until late
afternoon Thursday into Thursday night. Will lean in the
direction of the slower timing and areal coverage and keep at
chance of precipitation Thursday afternoon in the west and the
bulk of the precipitation later Thursday night.

Low pulls out to the east Friday and pulls the precipitation to
the east with it by Friday night.

Temperatures are expected to be on the increase through Friday
as warm air advection takes place in advance of the low pressure
system. Question is, how warm will it get in advance of the low
Friday. If dry slot wraps in like some models suggest, then
there is the possibility that I may be under cutting
temperatures for highs.

Cold air advection takes place Friday night in the wake of the
low pressure system as lows drop back into the 30s.

Long term /Saturday through Tuesday/
High pressure will build over the area behind the departing system
on Saturday. Cool northerly flow off the lake will keep temperatures
in the upper 40s and lower 50s with low clouds trying to clear out
through the day. Despite some increase in high cloud on Sunday,
better insolation should allow for a warming trend to develop.

Locations near lake erie may struggle to get out of the 40s with
continued east/northeast flow but most inland areas should push
into the mid and upper 50s.

Upper level ridge expands over the area on Sunday with another upper
level low moving out of the plains across the lower to mid
mississippi valley into Monday. Based on the current model
tracks, moisture should increase across the region on Monday
with chances of showers continuing into Tuesday. Will wait for
higher confidence in track before going with anything more than
just a chance of rain.

Aviation /18z Tuesday through Sunday/
A low cloud deck remains across the ohio valley and eastern
great lakes region beneath high pressure building southeast out
of canada. Ceilings range from ifr in most areas to MVFR at
tol/fdy early this afternoon. Drizzle is diminishing and expect
visibilities to improve at most sites. A gradual improvement to
MVFR ceilings is expected as well through 00z but uncertain
about the trends heading into tonight. Dewpoints will start to
drop off with some low level drying expected but otherwise think
several sites may drop back down to an ifr cloud deck as
inversion heights lower. Trended the forecast a little more
pessimistic overnight into tomorrow morning but should
eventually see improvement after 12z with locations starting to
scatter out across northwest ohio and near lake erie.

Outlook... Non-vfr developing again on Thursday and continuing
into Friday. Non-vfr possible through Saturday morning NE oh and
nw pa.

Marine
High pressure will expand across the eastern great lakes through
Wednesday maintaining northeast winds of 5 to 15 knots on lake
erie. Easterly winds will increase on the lake on Thursday as
the gradient tightens between high pressure over eastern canada
and low pressure approaching from the plains. Easterly winds are
expected to reach 20 to 25 knots on Thursday and a small craft
advisory will likely be needed on the western basin into
Thursday night when winds veer to the south. The low pressure
system will make slow eastward progress across northern ohio on
Friday, pulling a cold front south across the lake in its wake.

Northerly winds are not expected to be much more than 15 knots
with the front but the onshore flow will lead to choppy
conditions in the nearshore waters. High pressure will build
across the lake over the weekend.
