Area Forecast Discussion...CORRECTED
National Weather Service Cleveland OH
211 PM EDT Thu May 7 2020

.SYNOPSIS...
A ridge of high pressure over the local area will continue to
move east as a fast moving low pressure system moves southeast
across the lower Great Lakes region today. The low pressure
system will move northeast to Maine forcing a cold front south
across the area this afternoon and evening. Low pressure will
move northeast through the middle Mississippi Valley region late
tonight and force a warm front north to southern Ohio where it
will become nearly stationary by Friday morning. The low will
move east through the Ohio Valley Friday night followed by a
ridge of high pressure that will build east into the area over
the weekend. The ridge will force some unseasonably cold air
into the area for the weekend.

&&

.NEAR TERM /THROUGH FRIDAY/...
With this midday update lowered precipitation chances across
our east isolating them to northwest PA. Atmosphere is quite
dry. Temperatures are warming nicely and winds are gusting
around 35 MPH. Previous discussion follows.

A few cirrus continue to stream into the area but more
pronounced clouds upstream over the northern lakes will move
into our area today with a cold front. Showers will be scattered
over the eastern portions of the forecast area this afternoon
and satellite and radar both indicate this trend should continue.

Broad upper level troughiness will persist across the entire
eastern United States through the weekend. Some weak upper level
ridging will move southeast across the region today but then
flatten as it rounds the base of the mean trough this morning. A
small potent perturbation will move east across the central
Great Lakes causing a weak fast moving surface low to race
across the lower Great Lakes region and then to Maine by
tonight. This feature will force a cold front south across the
area later this afternoon and evening. Some limited moisture
associated with the cold front will move into the local area
with the front and result in a few scattered showers mainly
across the eastern portions of the forecast area this afternoon.
Another surface low pressure is expected to move northeast out
of the Middle Mississippi Valley region and across the Ohio
Valley by Friday. This system will tap into some copious
moisture from the Gulf of Mexico. As the warm front lifts north
across southern Ohio, it will become nearly stationary resulting
in a potential for some isentropic lifting ahead of the low.
Best axis of QPF is expected across the southern tier counties
of the local forecast area with lesser amounts near the
lakeshore. As the low pulls out to the northeast, the
precipitation will move east with it Friday afternoon.

Temperatures will recover slightly into the middle 50s east
around 60 central and middle 60s in the west today as the ridge
of high pressure affects the local area. Cooler temperatures in
the east will result from the close proximity to the low
pressure system and passage of the cold front this afternoon.
Lows tonight look like they will be similar to this morning with
lower 30s in the east to middle and upper 30s elsewhere.
However, clouds will be spreading in from the west overnight and
this should prevent the development of frost. Exception may be
inland northwest Pennsylvania counties where lows could drop
into the lower 30s. Friday will struggle to get out of the 40s
once again due to the cold air advection and expected rainfall
and cloud cover.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
The short term begins Friday night with low pressure near Baltimore/
Philadelphia area with northerly flow across Lake Erie and into the
area behind the low. Temps at 850mb over the lake range from -7C on
the GFS to -10C on the NAM. By 12Z Saturday both models show a
highly anomalous -11 to -12C over the lake.  The forecast sounding
on BUFKIT shows the extreme instability develops over the lake with
around 800 J/KG of lake induced CAPE and an EL around 14kft.
Moisture isn't optimal the first half of the night but after
midnight that changes. Expecting rain/snow to be ongoing at the
beginning of the period with precip changing to all snow through the
evening and continuing overnight.  Winds do back through the night
which may keep things from getting too organized. Expect precip to
continue off the lake Saturday with snow changing back to rain
through the late morning and afternoon as temps slowly rise.
Saturday night 850mb temps rise to -3 to -4c allowing lake effect
precip to diminish. Sunday models bring a system east across the
area and will have high chance to likely pops for rain. Highs 40s
and lower 50s.

&&

.LONG TERM /MONDAY THROUGH WEDNESDAY/...
Monday we could see a few showers, mainly rain, east half as wrap
around moisture exits east. Monday night through wednesday look dry.
Highs Tuesday in the 50s.  Highs Wednesday upper 50s to near 60.

&&

.AVIATION /18Z Thursday THROUGH Tuesday/...
Low pressure will move across the southern Great Lakes this
afternoon and evening, allowing for some lower VFR ceilings
along with a chance of showers in Northwest Pennsylvania late
this afternoon and early this evening. West to Northwest winds
of 15 to 20 knots with gusts of 30 to 40 knots will persist
through this afternoon, but will diminish this evening and will
predominantly be out of the northeast on Friday. More rain will
move into central Ohio Friday morning as low pressure moves into
the Ohio Valley and MVFR and IFR ceilings are possible within
showers in southern areas on Friday morning and afternoon. The
rain will exit to the east by Friday evening.

Outlook...Non-VFR possible at times through Saturday, then
again Sunday and Monday.

&&

.MARINE...
Extended the Small Craft Advisory up along the lakeshore towards
Ashtabula. Whitecaps are evident in webcam imagery northeast
along the lakeshore with west winds 20 to 25 knots, gusting up
near 35 knots in some spots.

A cold front will cross Lake Erie this afternoon turning southwest
winds more wnw at 10 to 15 knots. The pressure gradient will
increase tonight into Friday as low pressure moves through the lower
Ohio Valley.  Expect northerly flow to increase Friday afternoon and
evening to 15 to 20 knots and continue from the northwest around 20
knots overnight and through saturday before backing to west and
diminishing slowly Saturday night.  Winds will increase to around 15
knots from the northwest again Monday as low pressure passes to our
east and a large area of high pressure moves in from the west. No
headlines at this time however expect a small craft advisory will be
needed for Friday night through Saturday night east of the islands.
