Special Weather Statement, NWS Cleveland, OH

Area Forecast Discussion
National Weather Service Cleveland OH
946 AM EST Thu Jan 12 2017

.SYNOPSIS...
A slow moving cold front over the area will push off to the
southeast into tonight. High pressure over minnesota will move east
over the area friday, weaken some saturday then rebuild over lake
erie sunday before moving off to the northeast monday. A series of
lows will come out of texas monday through wednesday and move
northeast into the area along a slow moving cold front.

&&

.NEAR TERM /THROUGH TONIGHT/...
Already getting reports of flooding and more heavy rain is on the
way as the wave over Indiana will move through this afternoon. It
looks like locations along the U.S. 30 corridor will get a break
from the rain for a short period which will help. Have added
thunder to the forecast for the southern end of the area as there
is good shear and record high moisture values for this time of
year. Have adjusted temps to account for current readings and
added some fog to areas north of the front.

Previous...As the wave along the cold front moves ne of leri it
should provide the kick to keep the front moving se to be near the
oh river by 00z this evening. The overrunning rain behind the
front should shift into just the se by the end of the day. The
airmass is unstable enough for some thunder to occur but not any
severe wx.

The bigger issue is possible flooding from added rain today and
melting snow and ground that may still be partially frozen in some
spots. Will continue with the flood watch that goes thru this
evening for roughly the east half of the cwa. Including the current
rainfall since midnight, all but the nw should see two-thirds to an
inch and a quarter of rainfall thru this afternoon.

&&

.SHORT TERM /FRIDAY THROUGH SUNDAY NIGHT/...
As high pressure builds toward the area from the nw, the remaining
good moisture should get pushed se of the cwa by midnight, so the
precip should be done by then. Colder air gradually pushes se across
the cwa tonight with lows expected to be into the low to mid 20s by
daybreak fri.

The high pushing east across the lake should keep conditions dry
with seasonal temps fri. As the high shifts off to the ne fri night,
moisture will quickly spread ne back across the area with possible
light wintry precip developing in the south by the end of fri night
but a little more likely on sat. However...there are still model
differences for sat on how far north this precip will push.

The wave responsible to the possible precip on sat will move east
thru VA by midday sun while high pressure over the upper midwest
builds into lake erie. This should push the moisture and precip
threat se of the cwa for sun then things are expected to start to
change again by late sun night.

The first in a series of lows should come out of TX and move nne
toward lmic by late mon night. The mid and upper flow from the sw
will rapidly push overrunning moisture ne into the cwa sun night.
Aloft it currently looks to be too warm for snow by the end of sun
night for much of the cwa so this could be a situation for fzra to
occur as ground temps may not rise enough to get above freezing
before the precip arrives.

&&

.LONG TERM /MONDAY THROUGH WEDNESDAY/...
The long term begins on Monday with models showing an upper low over
KS and a short wave ridge just to our west. At the surface a warm
front will extend east from low pressure in KS into the lower Ohio
Valley. The airmass across the region will be fairly moist and both
the GFS and ECMWF show low/mid level flow into the area out of the
GLFMX. The surface low will move northeast across the Great Lakes
Tuesday into Canada on Wednesday dragging a cold front through the
area late Tuesday and Wednesday. Ahead of the cold front the pattern
is very wet so will have high chance and likely pops starting Monday
night and continuing through Wednesday night. Precip type will be
rain with the exception of early monday morning where we could get a
r/s/zr mix...and late wednesday night when a r/s mix is possible.
Temps above normal.

&&

.AVIATION /12Z Thursday THROUGH Monday/...
Cold front working its way east/southeast across the area
extending now from near a CYXU-KTDZ-KTYQ line. Line of showers
with possibly a little embedded thunder was ahead of the front and
covered most southern and eastern counties. Currently expecting
the front and associated precip to slow to a crawl this morning as
a wave of low pressure rides northeast along the front. This
afternoon the front will move southeast of the area as the wave
move northeast. For this morning am expecting IFR fog across sern
lwr MI to drop into the northwest. Also expecting IFR along the
central lakeshore and into KCLE. Elsewhere conditions will remain
mainly MVFR into the morning hours but will likely drop to IFR and
lower cigs drop into the area post front. Expecting IFR lifting to
MVFR overnight most places.

OUTLOOK...Non-VFR possible Thursday night through Friday and again
Saturday through Saturday night.

&&

.MARINE...
Will allow the small craft on the western basin to end at 4pm as
planned. Could be close right at 4am but winds will be dropping
quickly as the cold front moves in from the northwest. Will continue
the rest of the small craft headline as is through 10am. The cold
front will drop southeast of the lake this afternoon.  High pressure
will build in across the central lakes on Friday keeping the primary
flow out of the northwest. Winds will be light but turn northeast to
east friday night as the high passes to our north. Flow will remain
light Saturday through Monday.

... Dense fog has formed near the lake erie shoreline...

Dense fog has moved inland from Lake Erie this morning mainly
along the I-90 corridor of Northeast Ohio and Northwest Pennsylvania.
The fog is reducing visibilities in some areas to less than a
quarter mile.

The fog will likely remain for a few hours through late morning.
Conditions are expected to improve this afternoon as an approaching
cold front moves toward the region.

Motorists in the region should use caution as visibilities may
rapidly drop to near zero.
