Synopsis
Low pressure will move northeast across the western basin of
lake erie this afternoon. A warm front will lift north across
the eastern half of ohio and northwest pennsylvania today. A
strong cold front associated with the low pressure system is
expected to move from west to east across the local area late
this afternoon into this evening. A ridge of high pressure will
build slowly east across the area following the cold front
tonight through Sunday night. High pressure will then build into
the tennessee valley Monday and off the virginia coast Tuesday.

Near term through Sunday
A lot going on in the next 36 hours with strong deepening low
pressure expected to move northeast toward the western basin of
lake erie today. This storm system is expected to force a warm
front northeast into the eastern portions of the forecast area.

A secondary surge of warm air will arrive late this afternoon
and will push temperatures into the lower 60s from cleveland to
mansfield east. Dewpoint temperatures will also climb into the
50s as well across the same area. Areas further west will be
closer to the low and will struggle to get out of the 50s today.

There will be a few rounds of precipitation today. The first
round is currently moving east across the area at this time. The
second round is already beginning to develop along the warm
front across central indiana to central ohio. This area of
showers and possibly a few thunderstorms will move north toward
the forecast area during the early daylight hours today and lift
northeast with the front. The warm front appears it will stall
along the lake shore as the low moves northeast forcing another
line of showers and thunderstorms across the area with the cold
front.

As of right now, with potential break in the precipitation this
afternoon in the eastern half of the area, some breaks in the
overcast could occur helping somewhat to boost temperatures in
the east. Most unstable CAPE values approaching 1000 in the east
and 850 mb winds reaching 60 knots in the nose of the low level
jet. SPC has a marginal risk for severe thunderstorms nosing
into the forecast area but I think this evening the area will
need to be extended northeast up toward erie, pa. So, main
threat will be from damaging winds in any thunderstorms that tap
into the winds aloft. Quite a bit of shear is noted up near the
warm front so will have to closely monitor any storms that
develop this afternoon and evening.

As cold front pushes east, colder air will follow but models are
slowing the forward progress of the cold air and will likely
hold off until Sunday afternoon. So, will cut back on colder
temperatures tonight and Sunday and then begin to drop
temperatures off in the afternoon when the colder air finally
arrives. Snow totals will be reduced as well and most likely any
accumulations will be confined to higher elevations in the east
tonight.

Due to the gusty wind in the mid levels mixing down to the
surface behind the cold front, expect the potential for gusty
winds at the surface and will continue the wind advisory across
the area.

Short term Sunday night through Tuesday night
The best chance for lake effect snow seems to be Sunday night into
Monday morning as the next short wave drops across the eastern great
lakes and the core of the coldest air slides by. The northwest flow
will back to westerly and eventually southwesterly on Monday so the
focus of the lake effect will shift from inland locations to include
the lakeshore by Monday morning. Several inches is certainly
possible especially in the hills in erie county pa and if a
persistent band of snow were to develop then somebody could have a
decent shot of snow before the snow weakens and shifts toward
buffalo by Monday afternoon. Warm advection increases on Monday and
outside of extreme NE oh and NW pa, there will likely be just some
patchy mid and high clouds and it should begin to warm up with highs
in the 40s.

There are still some timing issue with the next front on Tuesday.

The GFS remains somewhat faster than the other models and the
forecast will stay a few hours slower than the gfs. Will keep
Tuesday dry with high temperatures up to around 50 in many areas.

Will mention a chance of rain snow showers Tuesday night, mainly
across NE oh and NW pa.

Long term Wednesday through Friday
Just cold enough for some lake effect rain snow showers flurries on
Wednesday with highs in the 30s. The lake effect could linger into
Thursday but a zonal flow aloft late in the week will take the
surface high off the mid atlantic coast and winds will back to the
southwest on Friday. The next front will likely sag south across the
great lakes sometime early next weekend.

Temperatures will remain below normal Wednesday and Thursday, then
recover toward normal by Friday.

Aviation 06z Saturday through Wednesday
Big changes on the way over the next 24 hours. Low pressure is
progged to move northeast across the southeast lower michigan
and western lake erie. This storm system will force a warm front
to lift northeast across the area today. A secondary surge of
warm air will lift northeast later this afternoon across areas
southeast of cleveland and east of mansfield. The warm surge may
even lift northeast into erie this evening. In the mean time,
expecting line of showers and embedded thunderstorms to move
east across the area this morning. There will be a short break
in the activity before another surge develops around 12z in the
morning and pushes northeast along the developing warm front.

As cold front pushes east into the area, strong wind gusts are
possible in the most intense showers and thunderstorms and could
bring wind gusts to 45 knots or possibly higher to the surface
after 20z across the area until about 02z this evening. Ifr with
brief lifr possible with the cold front as well.

Outlook... Non-vfr continues through Sunday and into Monday
across northeast ohio and northwest pennsylvania.

Marine
Low pressure will track across the western basin of lake erie today.

There is some question as to whether the low will track into ontario
or perhaps track northeast along the spine of lake erie. In any
case, a south to southwest flow will continue today ahead of the
low. The air mass is rather stable and the marine layer will likely
prevent efficient mixing until the low and associated cold front
sweeps across the lake from west to east this afternoon and evening.

Will have to watch water levels in the western basin but there are
currently equipment outages so we have limited information. Masters
may want to call the coast guard for water level information before
navigating the western basin to and early tonight.

The west to northwest gales behind the system will persist into
Sunday morning on the western basin and Sunday afternoon on the
eastern basin. Small craft advisories will be posted as the gale
warnings come down.

Winds will gradually back to southwest on Monday ahead of the next
cold front and a brisk southwest flow will continue until the
frontal passage late in the day Tuesday. Small craft advisories may
need to continue with the brisk southwest flow and will certainly be
needed again after the next cold front.

High pressure will build in from the west on Wednesday and winds
should begin to calm down on the lake.
