1059 AM CDT Mon Jun 21 2021

Areas affected...Eastern Ohio...Western Pennsylvania...southwest New
York...and portions of West Virginia

Concerning...Severe potential...Watch likely 

Valid 211559Z - 211730Z

Probability of Watch Issuance...80 percent

SUMMARY...A severe storm threat is expected to increase over the
next 1 to 2 hours. A watch is likely.

DISCUSSION...Showers have developed along the cold front in
east-central Ohio. Expect these showers to develop into
thunderstorms and strengthen as the boundary layer warms and
destabilizes ahead of this activity. Dewpoints are in the upper 60s
to low 70s across much of the Upper Ohio Valley and into the
Northeast. 12Z RAOBs show deep moisture near the surface which
suggests dewpoints likely won't decrease much, even as the boundary
layer mixing deepens. Therefore, an unstable airmass is forecast
with MLCAPE in excess of 2000 J/kg. The 1530Z VWP from KCLE observed
the vertical wind profile well which, as expected, is similar to the
PIT 12Z RAOB. Winds as high as 35 to 40 knots extend as low as 1 km
with mid-level flow around 50 knots. This shear profile will be
supportive of organized convection including supercells and bowing
line segments. In addition, the strong flow within 1km of the
surface should aid downward transport of strong winds. Therefore,
damaging winds are expected to be the primary hazard. Large hail may
also occur, especially with any supercells which may develop. In
addition, strong speed shear in the low-levels could support the
threat of a tornado or two, but veered surface flow will likely
preclude a greater tornado threat.

Valid 211300Z - 221200Z

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE UPPER
OHIO VALLEY AND MID-ATLANTIC INTO NORTHERN NEW ENGLAND...

...SUMMARY...
Isolated to scattered severe thunderstorms are expected from the
upper Ohio Valley and Mid-Atlantic into northern New England,
offering damaging gusts, sporadic severe hail, and perhaps a couple
of tornadoes.

...Synopsis...
A high-amplitude mid/upper-level pattern is in place and will
continue through the period -- featuring:
* A longwave trough from north of Hudson Bay to the northern Gulf of
Mexico,
* Ridging from northern MX northwestward to WA/ID, and
* A quasistationary to northward-drifting cyclone off the CA
coastline.

Numerous shortwave troughs and related vorticity maxima (some
convectively generated/enhanced) will pivot through the cyclonic-
flow field from the northern/central Rockies to the mid/upper
Mississippi Valley and northeastern CONUS.  The most prominent is a
perturbation now apparent in moisture-channel imagery from Hudson
Bay across northwestern ON to northern MN.  This feature will pivot
across the upper Great Lakes through this evening, before turning
northeast and weakening late tonight.

At the surface, 11Z analysis showed a strong/992-mb surface low near
PLN, with cold front southward over northeastern IN then
southwestward across southern IL, southern MO, southwestern OK, the
TX South Plains, and central NM.  As the low ejects northeastward
over western QC by 00Z, the front should reach western portions of
NY/PA/WV, southwestward to mid TN, northern MS, and central/
southwest TX.  By 12Z, the front should reach ME, NJ, the Blue Ridge
region of VA/NC, to northern AL, south-central TX, and Chihuahua.

...Northeast...
Remnants of small MCSs are noted this morning over northwestern PA
and northern NY, each trailing outflow boundaries extending over
western NY and north-central OH.  The MCV from the trailing area may
aid convective potential over western/northern NY later this
morning.

Otherwise, scattered thunderstorms are expected to develop from late
morning through early afternoon across western parts of the outlook
area, along and ahead of the surface cold front.  Initial severe
potential should arise from the Lake Erie vicinity across portions
of OH, western PA and western WV, as the boundary layer destabilizes
diabatically (and in some areas near the Great Lakes, recovers
behind morning convection).  Activity should move eastward to
northeastward through the rest of the afternoon.  Most of the
convection should evolve into broken to solid lines, though
early-stage supercells are possible given the favorable wind
profiles.  Damaging gusts (including some potentially exceeding
50-kt severe limits) will be the main concern, though isolated
severe hail may be observed in any supercells, along with a tornado
or two.  An isolated, localized threat for QLCS tornadoes also may
develop where any line of convection encounters higher SRH -- mainly
near boundaries left behind by the morning activity.

Rich moisture and weak MLCINH will support early development and
afternoon-long maintenance of convection across the outlook area.
Lower-elevation surface dew points should be commonly in the
mid/upper 60s F, with 70s east of the mountains in the lowlands of
the Potomac/Chesapeake Bay/Delaware Valley areas.  Diurnal heating
will be more sporadic/fragmented in northern parts of the outlook
area due to passing areas of cloud cover from earlier/upshear
convection.  Still, a broad prefrontal corridor of 1000-1500 J/kg
MLCAPE should develop, locally near 2000 J/kg.  Tightening height
gradients aloft -- both related to general/regional  synoptic height
falls and the upper Great Lakes shortwave trough -- will strengthen
mid/upper winds over the region.  However, the strongest flow aloft
should remain behind the front, and mid/upper winds will carry a
substantial front-parallel component.  Forecast soundings suggest
preconvective effective-shear magnitudes generally in the 35-45-kt
range over NY/PA/northeastern OH, and 25-35 kt southward from there.

...KY/TN to central/south TX...
Widely scattered to numerous thunderstorms will form on both sides
of the front today.  Locally damaging/isolated severe gusts are
possible from frontal and warm-sector convection, primarily this
afternoon into evening.  Severe concern will be widely dispersed and
primarily along/ahead of the front, though a rogue hail-producing
cell cannot be ruled out behind the front across the southern
Plains.  A general increase in diurnal heating and low/midlevel
lapse rates, but decrease in vertical shear and frontal slope, will
be noted with southwestward extent along/ahead of the front, from
the northern/central Cumberland Plateau southwestward to south TX. 
Rich low-level moisture will support MLCAPE in the 1500-2500 J/kg
range from the Mid-South northeastward, and 2000-3000 J/kg farther
southwest where midlevel lapse rates are greater in closer proximity
to the EML.  Water-loaded downdrafts and mesobeta-scale cold-pool
surges (with low predictability at this range) will pose the
greatest concern for damaging wind.

...Interior OR, extreme northern CA...
Late this afternoon into evening, isolated to widely scattered
high-based thunderstorms are expected to develop across areas near
the OR/CA line and move northward to northwestward, with the threat
for isolated severe gusts.  This potential will grow in step with
increasing low-level moisture through the afternoon, as the upper
ridge moves east of the area and strongly difluent flow sets up
northeast of the Pacific cyclone.  Moist advection should offset the
effects of antecedent vertical mixing processes more with time,
increasing PW to between 0.75 and 1 inch tonight.  Weak deep shear
will limit overall organization, but gust potential will be aided by
a deep, well-mixed subcloud layer supporting downdraft acceleration.
See the SPC day-1 fire-weather outlook for concerns regarding dry
thunderstorms over this region.

BULLETIN – EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
1133 AM EDT Sat Apr 13 2019

The National Weather Service in Greenville-Spartanburg has issued a

* Flash Flood Warning for…
Southeastern York County in Upstate South Carolina…

* Until 530 PM EDT Saturday.

* At 1127 AM EDT, Doppler radar indicated thunderstorms producing
intense rain across the warned area. One to two inches of rainfall
has already occurred from Newport and Rock Hill to Fort Mill and
the NC/SC state line and an additional one to two inches of
rainfall is imminent across the area, prompting an upgrade from
a Flood Advisory to a Flash Flood Warning as additional flooding
is expected to rapidly develop.

* The additional rainfall will likely impact several roads and
even some homes, businesses, and other structures, especially
within the Rock Hill area. If you are in a low-lying area or
near a creek or stream, please seek higher ground immediately!

* Some locations that will experience additional flooding include…
Rock Hill, Fort Mill, Tega Cay, Lesslie, Carowinds and Newport.

* Numerous small streams in the warned area are experiencing
rapid rises and flooding of adjacent areas is likely over the
next 30-90 minutes. Some streams and associated tributaries
include: Manchester Creek, Big Dutchman Creek, and Wildcat Creek.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

Excessive runoff from heavy rainfall will cause flooding in urban
areas. Storm drains, streams and other drainages will become
overwhelmed by excessive rainfall, flooding low-lying roads,
intersections, and parking lots. Underpasses are especially dangerous
because sudden flood waters can quickly surround and submerge your
vehicle. Stay alert and avoid flood-prone areas.

Numerous roads, parking lots and bridges will be threatened by heavy
rain and rapidly rising streams and creeks. Please pay close
attention to road signs indicating a flood-prone area. Obey all
barricades, even if water is not currently over the road. Barricades
are in place for your protection and indicate areas where flooding
can occur rapidly and without warning.

When it is safe to do so, please report flood waters or landslides
flowing over roads or threatening property to the National Weather
Service by calling toll free, 1, 800, 2 6 7, 8 1 0 1, by posting on
our Facebook page, or via Twitter using hashtag NWSGSP. Your message
should describe the event and the specific location where it
occurred, including roadways, nearby cross streets, stream names and
other landmarks.
