.SYNOPSIS...
Low pressure will slowly move east across the area tonight
through Friday. High pressure will build in from the west for
the weekend.

&&

.NEAR TERM /THROUGH THURSDAY NIGHT/...
High pressure will drift east of the area this evening, allowing
low pressure to meander east across the region during the near
term period. The low will lift a warm front this evening and
isentropic ascent will allow PoPs to increase towards 00Z/8 PM
this evening. With that being said, the lower levels are quite
dry as of 3 PM EDT with dew point depressions as high as 20 to
25 degrees and RH values of 30 to 40 percent in most spots.
Precip will slowly spread east through tonight and reach eastern
zones by late tonight or early Friday morning. Precipitation
may struggle to reach the surface at the start, but there`s
still some potential for evaporational cooling as the lower
levels begin to moisten. A brief period of rain/snow remains in
the realm of possibility east of I-71, but the better chance of
snow or a rain/snow mix lies east of the I-71 corridor and
especially across NW PA and far NE OH where nighttime temps
won`t be battling against the April sun angle. If snow does
occur, worst case scenario may be a light dusting on
grassy/elevated surface outside of NE OH/NW PA with perhaps a
few tenths of an inch of snow possible in the higher terrain of
the primary snowbelt. Not anticipating travel impacts since
surface temps will bottom out at near or perhaps a degree or two
below freezing in inland NW PA. Any snow will transition to rain
by 12Z/8 AM Thursday.

The more stratiform rain will exit to the east by early to mid
afternoon, however scattered wraparound light showers/mist and
possibly patchy fog will continue through the remainder of the
near term period as the low inches east across the CWA.

Tonight`s lows will be in the 30s and expect max temps in the
mid to upper 30s to lower 40s on Thursday. Thursday night`s lows
will drop into the mid to upper 30s.

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
An elongated upper level trough will extend from the Great Lakes
Region to the Gulf Coast on Friday. While the base of the trough
curls northeast through the Carolinas with low pressure tracking up
the East Coast, another piece of upper level energy will reside over
the eastern Great Lakes. Moisture is forecast to wrap around the
back side of the northern upper level low on Friday along with upper
level cold pool temperatures of -25C at 500mb. Add in the slow
moving cold front in the low levels that gradually sweeps east on
Friday and scattered light showers look reasonable. Coverage is
expected to be limited so capped pops at 30-40 percent for now with
some differences in the models about where the better upper level
moisture and support will be located. Temperatures will be cool on
Friday with continued northerly flow off Lake Erie and 850mb
temperatures of 0 to -4C.

The upper level trough axis makes slow eastward progress through the
day on Saturday. Meanwhile most models show high pressure gradually
building in from the west. The GFS is the exception which holds onto
a stronger surface low near Delaware while the other models move off
the East Coast. Will hold onto a low pop in the northeast on
Saturday but in general expect most of the area to see dry
conditions on Saturday. Temperatures will remain cool in the upper
40s to lower 50s in the far west. With skies clearing out and high
pressure overhead, temperatures will drop into the lower 30s again
on Saturday night.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
The long term starts off with dry conditions on Sunday and continues
through much of the day on Monday with ridging overhead. A warming
trend is expected with highs on Monday back into the upper 60s to
near 70 degrees. Models have come into much better agreement on the
12Z model suite with the next trough moving across the northern
states to the Great Lakes Region by Monday night. Low pressure is
forecast to be near Lake Superior on Monday with a cold front
sweeping east across the area late Monday. With this we did hold
onto low chance pops Monday afternoon into Monday night. The window
for moisture advection is short and may be a limiting factor for
precipitation but will be monitoring the evolution of this system
over the coming days. Can not rule out a chance of thunderstorms
with the front on Monday but for now instability is limited. Another
push of cold air arrives behind the front for the mid-week period
with temperatures likely below normal for Wednesday.

&&

.AVIATION /18Z Wednesday THROUGH Monday/...
Low pressure will meander into the region during the TAF period.
Rain will move east into the area between 21Z and 00Z before
slowly spreading east through mid to late morning Thursday. A
rain/snow mix is possible for a period from KCLE to KMFD east
later tonight, but expect any snow to transition to rain as
temps rise after 12Z Thursday. Stratiform precip should taper
off from the west Thursday morning, but wraparound showers will
stick around through the remainder of the TAF period.

As far as cigs/vsbys go, conditions will deteriorate to MVFR
within the first couple of hours of precip onset with IFR and
possibly LIFR developing a couple of hours later. Even after the
stratiform rain moves out, IFR will likely persist in lower
ceilings and mist/fog/lingering showers through 18Z Thursday.

South/southwest winds 10 knots or less will shift to the
southeast tonight and increase to 5 to 10 knots by early
Thursday morning. Wind direction will become more variable as
the low moves into the area in the last couple hours of the TAF
period.

Outlook...Non-VFR expected with rain through Thursday, then
lingering low level clouds into Friday.

&&

.MARINE...
Southeasterly winds of 10-20 knots will develop tonight as low
pressure moves into western Ohio. Winds back to more easterly
through the day and then eventually to the north as the surface low
tracks to eastern Lake Erie by Thursday night. The northerly winds
and tightening pressure gradient behind the surface low will result
in building waves for a window of time Thursday night and a somewhat
Small Craft Advisory may be needed for a portion of Central Lake
Erie. Northerly winds around 15 knots will continue Friday and
Friday night as a trough lingers across the eastern Great Lakes.
Another low pressure system is forecast to track up the east side of
the Appalachians on during this time frame. If it is stronger or
takes a more westerly track then it could enhance northerly winds on
Lake Erie with prolonged Small Craft conditions.

High pressure builds overhead late Saturday through Sunday. Low
pressure will move through the Upper Great Lakes on Monday, pulling
a cold front east across the lake Monday night. Westerly winds will
increase behind the front on Monday night.
