.SYNOPSIS...
A cold front will move south of the area tonight. High pressure will
east across the Great Lakes Region tonight through Tuesday before
setting up off the New England coast on Wednesday. Meanwhile an
upper level ridge will strengthen over the region through Thursday
with a weak cold front arriving on Friday.

&&

.NEAR TERM /THROUGH MONDAY NIGHT/...
A cold front bisects the area this afternoon and can be seen on
radar imagery with a broken line of showers. Thus far we have not
seen any lightning with these showers but isolated thunderstorms
remain possible as this boundary continues to settle south through
the evening. Mixed layer CAPE has been decreasing as we cloud up
with generally between 250-500 J/kg of skinny CAPE. Storms have
struggled to get very tall with warm air in the mid-levels but are
producing efficient rainfall. Otherwise the remnant of the upstream
AM MCS is mostly passing south of the area with decaying showers
reaching our southwestern counties.

Northerly flow behind the front will bring falling temperatures and
humidity overnight. High pressure will build south out of Canada
into the Upper Great Lakes then to the eastern Great Lakes through
Monday night. Highs on Monday will be in the mid 70s to near 80
degrees but more noticeable will be the dewpoints falling by 10-15
degrees into the mid and upper 50s. Skies will tend to clear
overnight and this will make for pleasant weather on Monday with
mostly sunny skies.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/...
High pressure will continue to influence the region Tuesday into
Wednesday as the center builds from the Eastern Great Lakes region
to off the New England Coast. This will maintain dry conditions but
temperatures will begin to trend back up on Wednesday as the warm
front lifts north of the region. A broad upper level ridge expands
overhead with 500mb heights of 594dm reaching near or just north of
Lake Erie. Before the ridge fully gets established we may be
watching MCS activity across the Upper Midwest or Lake Michigan
Tuesday night but it does look far enough removed from the region to
maintain a dry forecast with the warm front. Dewpoints also lag
behind the warming temperatures and will be in the 60s on Wednesday
keeping the heat index within a few degrees of the temperatures.

&&

.LONG TERM /THURSDAY THROUGH SUNDAY/...
Thursday is expected to be the hottest day of the week as both
temperatures and humidity continue to climb. Dewpoints creep up into
the low 70s across much of the area while highs are in the low 90s.
This does give some heat index values at or above 100 degrees across
Northwest Ohio and extending east along the lakeshore to Cleveland.
Will need to continue to monitor trends over the coming days but
could potentially need a Heat Advisory for a portion of the forecast
area. Was able to remove pops from Thursday with this cycle given
generally dry air overhead and a capped atmosphere. If we end up
getting a lake breeze then can`t rule out a few thunderstorms along
that boundary. However with ridge of high pressure to south and low
pressure moving into the Upper Great Lakes, this seems like a lower
chance for a lake breeze.

The upper level ridge starts to break down on Friday as a shortwave
trough crosses the Great Lakes region and a cold front starts to
sink south into the area. Continued with high pops (around 60%) for
the afternoon but will have to see if southern areas are too far
removed from the forcing to get storms. Then continued with chances
of showers and thunderstorms for Saturday and Sunday as the front
looks to stall in the vicinity with either a quasi-zonal or
northwest flow pattern setting up aloft. Temperatures will be
impacted by coverage of clouds and thunderstorms but generally look
to remain at or above normal through the extended.

&&

.AVIATION /18Z Sunday THROUGH Friday/...
Primarily VFR with pockets of MVFR ceilings scattered across
northern Ohio and Northwest Pennsylvania this afternoon.
Scattered showers with isolated thunderstorms will be possible
this afternoon and early evening. Best chance for TS will occur
across southwestern TAF sites, mainly KFDY and KMFD. Opted to
include VCTS with this forecast update with -SHRA elsewhere.
Showers may drop cigs/vis to IFR/MVFR at times through ~22Z/Sun.
High pressure builds south over the area from the Upper Midwest
by tonight allowing for cloud cover to gradually scatter out
from north to south. Can`t rule out some patchy radiation fog
overnight tonight/daybreak Monday. However, confidence in exact
timing and locations impacted remains low with this forecast
iteration.

Northwesterly to northerly winds 5-10 knots are expected
through this evening. Winds diminish to 5 knots or less
overnight tonight while turning northeasterly. Winds will
increase to 5-10 knots by late Monday morning.

Outlook...VFR expected through Wednesday outside of any
radiation fog impacts to terminals. Isolated showers and
thunderstorms with non-VFR are possible on Thursday.

&&

.MARINE...
A ridge of high pressure building south from the Upper Midwest will
push a cold front south of the lake tonight. Elevated northerly
winds 10-20 knots may briefly allow for wave heights to build to 2-3
feet, with instances of 4 footers possible, across the central
basin. Winds gradually weaken to 8-12 knots and turn northeasterly
as the aforementioned ridge builds overhead on Monday. Generally
easterly winds 5-10 knots persist through Tuesday before the ridge
exits to the east and winds turn southerly Wednesday morning.
Southerly to southwesterly winds 5-15 knots will likely continue
across Lake Erie through the end of the week.
