1056 am edt Thu mar 30 2017
Low pressure over missouri will track toward northern ohio by
Friday. A warm front will push northeast ahead of the low with a
the cold front occluding by Friday. The low will move east of
the area by Friday night. High pressure from the upper midwest
will move overhead by Sunday.
Near term /through tonight/
Showers have blossomed since 6 am across northern ohio/nw pa as
the 850mb front lifts north. These have been accompanied by
numerous thunderstorms across the central portion of the area
this morning as the atmosphere destabilizes aloft. Showers are
expected to continue to develop across northern and eastern
areas into early afternoon before this first area of forcing
shifts north to lake erie.
Some breaks in the cloud cover are noted on visible satellite
across SW ohio where some pockets of drier air are located.
Although these breaks will try to expand northward, sufficient
low clouds should develop as the surface warm front lifts north
into the area that any breaks should be short lived. Low
pressure currently located near st. Louis with a warm front
extending eastward toward the ohio river valley at 10 am.
Surface warm front will lift north into the area after 2 pm but
will struggle to push north as we hold onto an easterly flow
near lake erie into this evening. Southerly flow with temperatures
surpassing the 60 degrees mark will likely make it as far north
as a bowling green to ashland line while points to the east
remain cooler with a southeasterly wind and tight thermal
gradient. The toledo area and portions of NW pa will not make it
out of the 40s.
Thunderstorms expected to fill in from the west late this
afternoon as a 120 knot upper level jet reaches western ohio.
The area that is forecast to reach the warm sector is included
in a slight risk for severe thunderstorms today. Surface based
instability will be the limiting factor and not expecting more
than 500 j/kg to work with. Even that will be a brief window
through roughly 10 pm when the front occludes and sweeps
eastward. Convection this evening will pose a wind/hail threat
but can not rule an isolated tornado given the strongly backed
flow with warm front stalled in the vicinity. As we lose
instability a hail threat may persist into the overnight hours
as the front moves eastward.
Original "today" discussion... Closed low tracking across the
plains is progged to slide a little south of east across
missouri before beginning to lift out toward ohio tonight. Wide
swath of warm advection and an increasing low level jet will
continue to generate warm advection showers this morning into
early afternoon. The showers will fight the dry boundary layer
but will continue to spread east and many areas will get at
least a passing shower or two. Cannot rule out a localized
rumble of thunder but would rather emphasize the thunderstorm
threat later today into tonight as the upper trough and occluded
front move in. Temperatures are tricky today with the warm
advection and clouds/showers and the warm front in the vicinity.
The models continue to advertise several rounds of convection
spinning around the low, the first which should arrive in northwest
ohio this afternoon. A little concerned for convection being
enhanced in the vicinity of the warm front which will likely remain
in northwest ohio. Favorable shear profiles will exist, little
surface CAPE but increasing CAPE aloft as well as a decent wind
field aloft. It may be difficult to establish a wind threat down to
the surface given the likely inversion but something to be watched.
The main round of convection ahead of the occluded front should
enter western ohio tonight and slide across the entire forecast
area with showers. There should be enough elevated CAPE for a
decent chance of thunderstorms although the highest threat may
remain just south of the forecast area. Areas that get several
rounds of showers/storms may end up with more than an inch of
Short term /Friday through Saturday night/
Showers and potentially a few rumbles of thunder will persist on
Friday especially across northeast ohio and northwest pennsylvania
Friday morning. The surface low and upper low will slide across the
forecast area and the lows may become more stacked allowing for a
more phased and deeper development of showers. Will have to watch
the QPF across NE oh/nw pa if the showers continue to redevelop in
the same areas.|
The system should move east Friday afternoon and evening and cooler
and more stable air will spread across the area. It will likely take
a while to shake the cloud cover on Saturday and a few showers could
linger in the snowbelt. Highs on Saturday only in the 40s except
perhaps lower 50s northwest ohio if the Sun comes out later in the
Long term /Sunday through Wednesday/
High pressure over the area Sunday will mean dry conditions and
temperatures in the lower and middle 50s. This high will begin to
slide off to the east Sunday night.
A complex upper-level and surface pattern is in store for late
Sunday night into Monday. A closed upper-level low will swing across
the tennessee valley Monday with an associated surface low
cutting from the deep south into the carolinas by Monday night.
A second, weaker upper-level trough will move eastward across
the northern great lakes region Monday. The GFS has a weak
surface low cutting northeast across the central great lakes due
to its more pronounced short-wave trough swinging through,
while the ECMWF keeps the surface low well north into canada
with near zonal flow across much of the great lakes.
With these significant differences between the models, what this
means exactly for our area is still uncertain. The southern low will
likely prevent ample deep moisture from making it this far north,
but there should be enough moisture around combined with some weak
forcing to at least get scattered showers across the area. The long
range global models differ in the exact tracks of these features,
with the ECMWF generally being the farthest north and the GFS being
the farthest south. Even with the GFS so far south, cutting off the
main moisture source, it still brings significant moisture into the
area Monday with widespread rain. It seems unlikely for this to
happen with such a strong low across the deep south, so have trended
more toward the emcwf - what else is new? For now have chance pops
everywhere until we get a better handle on how these features will
A ridge will build in behind the trough(s) Tuesday into Tuesday
night, bringing an end to the rain chances through at least
Wednesday morning. Another low will approach from the west Wednesday
evening into Wednesday night. This will bring widespread
precipitation to the area as a cold front moves through sometime
Wednesday night or Thursday. The exact timing is still uncertain,
but if the front holds off until Thursday, there will be a better
chance of seeing some thunderstorms.
Aviation /12z Thursday through Monday/
Scattered showers will continue this morning, mainly near the
lakeshore, with a few storms out near ktol and kfdy through
about 14-15z. MVFR conditions likely in the heavier rain. Aside
from some spotty drizzle or showers near the lakeshore late
this morning into this afternoon, most areas will stay dry with
vfr conditions until late this afternoon. Storms will move into
western ohio after 21z or so and make their way eastward.
MVFR/ifr conditions possible with these storms. Should arrive at
kcle/kcak after 23z - 00z. Additional showers and storms will
affect all terminals overnight with ifr/lifr conditions as fog
develops and ceilings lower.
Outlook... Non-vfr continuing into Friday. Non-vfr possible
Sunday night into Monday.
A small craft advisory continues for the western 2 lake nearshore
zones through 5 pm today as easterly winds should allow for waves to
reach 4 to 6 feet, highest during the late morning and early
afternoon hours. For the rest of the marine nearshore, winds should
be just offshore, which will prevent waves from reaching 4 feet.
Otherwise, winds are expected to be fairly light through the rest of
the forecast period.
