MD 1803 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR NORTHERN MINNESOTA INTO EASTERN NORTH DAKOTA AND FAR NORTHEAST SOUTH DAKOTA
Mesoscale Discussion 1803
NWS Storm Prediction Center Norman OK
0109 PM CDT Sat Aug 03 2024
Areas affected...northern Minnesota into eastern North Dakota and
far northeast South Dakota
Concerning...Severe potential...Watch possible
Valid 031809Z - 032045Z
Probability of Watch Issuance...40 percent
SUMMARY...Isolated cells may produce hail at times over parts of
northern Minnesota over the next couple hours. A greater risk of
severe hail and wind will then materialize later this afternoon
farther west with watch probability increasing.
DISCUSSION...Scattered cells persist north of a quasi-stationary
front across northern MN, as cooling aloft gradually sinks south.
Most storms this morning have been short-lived but a longer-lived
storms has developed with large hail reported. Given gradual warming
south of this boundary and southwest winds just off the surface,
these cells (though isolated) may persist as deep-layer shear is
favorable, with hail potential.
A greater risk of severe storms will likely develop by 21Z or so,
farther west along the cold front and where instability will become
stronger and surface based. Both large hail and damaging winds are
expected to develop from far southeast ND and northeast SD into
west-central MN, and a watch will likely be issued for that regime.

MD 1804 CONCERNING SEVERE THUNDERSTORM WATCH 591... FOR PORTIONS OF EASTERN PENNSYLVANIA...THE DELMARVA AND INTO WESTERN NEW JERSEY/SOUTHERN NEW YORK.
Mesoscale Discussion 1804
NWS Storm Prediction Center Norman OK
0153 PM CDT Sat Aug 03 2024
Areas affected...portions of eastern Pennsylvania...the DelMarVA and
into western New Jersey/southern New York.
Concerning...Severe Thunderstorm Watch 591...
Valid 031853Z - 032000Z
The severe weather threat for Severe Thunderstorm Watch 591
continues.
SUMMARY...Gradual upscale growth into bands and clusters is
possible through this evening. Damaging gusts are likely across
WW591.
DISCUSSION...The severe risk continues with scattered storms ongoing
across WW591 as of mid afternoon. Remaining inhibition has largely
been negated and additional storm development/intensification should
continue across much of the mid Atlantic. A few stronger cells have
emerged over eastern PA and northern MD/VA over the last couple of
hours. Early indications are that these storms may gradually evolve
into more organized clusters or linear segments with time owing to
the modest mid-level shear. Recent HRRR guidance also suggests
continued intensification is possible this afternoon. Damaging gusts
(some to as much as 60-70 mph) are possible with the strongest
storms should they begin to consolidate. Additional storms may also
develop through the day with at least an isolated severe risk
possible with any longer-lived clusters.

Valid 032000Z - 041200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE CAROLINAS
INTO THE MID-ATLANTIC AND PARTS OF SOUTHERN NEW ENGLAND...
...SUMMARY...
Severe thunderstorms are possible today over parts of Minnesota and
South Dakota, and from the Carolinas to southeast New York. Other
strong to severe storms may affect the Texas Panhandle, southwest
Florida, and central/northern Utah.
...20Z Update...
...Utah...
Strong heating and monsoonal moisture will promote scattered to
potentially numerous thunderstorms this afternoon, initially within
the higher terrain. A very weak MCV was evident in visible satellite
in south-central Utah which also may aid in storm development.
Overall buoyancy will be weak, but enough storm coverage and
subsequent cold pool development may promote organized outflow to
push into the Utah/Salt Lake Valley and surrounding areas by early
evening. A few strong to severe wind gusts will be possible.
Elsewhere, the previous forecast reasoning remains valid with only
minor changes based on observational trends and recent guidance.
..Wendt.. 08/03/2024
.PREV DISCUSSION... /ISSUED 1121 AM CDT Sat Aug 03 2024/
...Eastern States...
A large upper trough remains in place over the eastern states today,
with a broad/deep zone of seasonably strong southwesterly flow from
GA/Carolinas into New England. Visible satellite imagery shows
mostly clear skies in this corridor, where temperatures will climb
into the 90s and dewpoints will be near 70F. This will yield a
region of steep low-level lapse rates and ample CAPE for afternoon
thunderstorm development. Winds aloft will be stronger than
yesterday, and the proximity to the upper trough axis suggests
greater coverage of storms. This should result in a more active
convective day with several clusters of storms capable of damaging
wind gusts through the afternoon and early evening.
...MN/SD...
Fast northwest flow aloft across the northern Plains will maintain
steep mid-level lapse rates and occasional minor perturbations in
the flow through the forecast period across the Dakotas/MN. One
such feature has helped to initiate scattered thunderstorms over
northern MN this morning. This activity will likely increase in
coverage by mid afternoon and build southwestward into the very
moist/unstable air mass over central MN. Supercells capable of very
large hail and eventually damaging winds will be the main threat,
with eventual merger of outflows leading to bowing structures. It
is unclear how far westward the more active thunderstorm area will
extend, but have maintained the SLGT risk for eastern SD at this
time.
...TX Panhandle...
Satellite imagery shows a weak shortwave trough and embedded remnant
MCV over western KS. This feature will drift southward this
afternoon, aiding in the development of scattered thunderstorms over
southwest KS/southeast CO. Storms will spread southward into the
evening across the OK/TX Panhandles. 12z CAM solutions are a bit
more bullish on congealing outflows later today and the potential
for strong/damaging wind gusts across this region.
...FL...
Tropical Depression Four is slowly organizing over western Cuba. As
this system tracks northward to the west of the FL Peninsula,
low-level wind fields will slowly intensify through the night. This
would suggest the potential for a brief tornado or two with
convection in the outer bands of the system.

wind gusts through the afternoon and early evening.
...MN/SD...
Fast northwest flow aloft across the northern Plains will maintain
steep mid-level lapse rates and occasional minor perturbations in
the flow through the forecast period across the Dakotas/MN. One
such feature has helped to initiate scattered thunderstorms over
northern MN this morning. This activity will likely increase in
coverage by mid afternoon and build southwestward into the very
moist/unstable air mass over central MN. Supercells capable of very
large hail and eventually damaging winds will be the main threat,
with eventual merger of outflows leading to bowing structures. It
is unclear how far westward the more active thunderstorm area will
extend, but have maintained the SLGT risk for eastern SD at this
time.
...TX Panhandle...
Satellite imagery shows a weak shortwave trough and embedded remnant
MCV over western KS. This feature will drift southward this
afternoon, aiding in the development of scattered thunderstorms over
southwest KS/southeast CO. Storms will spread southward into the
evening across the OK/TX Panhandles. 12z CAM solutions are a bit
more bullish on congealing outflows later today and the potential
for strong/damaging wind gusts across this region.
...FL...
Tropical Depression Four is slowly organizing over western Cuba. As
this system tracks northward to the west of the FL Peninsula,
low-level wind fields will slowly intensify through the night. This
would suggest the potential for a brief tornado or two with
convection in the outer bands of the system.

Valid 032000Z - 041200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM THE CAROLINAS
INTO THE MID-ATLANTIC AND PARTS OF SOUTHERN NEW ENGLAND...
...SUMMARY...
Severe thunderstorms are possible today over parts of Minnesota and
South Dakota, and from the Carolinas to southeast New York. Other
strong to severe storms may affect the Texas Panhandle, southwest
Florida, and central/northern Utah.
...20Z Update...
...Utah...
Strong heating and monsoonal moisture will promote scattered to
potentially numerous thunderstorms this afternoon, initially within
the higher terrain. A very weak MCV was evident in visible satellite
in south-central Utah which also may aid in storm development.
Overall buoyancy will be weak, but enough storm coverage and
subsequent cold pool development may promote organized outflow to
push into the Utah/Salt Lake Valley and surrounding areas by early
evening. A few strong to severe wind gusts will be possible.
Elsewhere, the previous forecast reasoning remains valid with only
minor changes based on observational trends and recent guidance.

...Eastern States...
A large upper trough remains in place over the eastern states today,
with a broad/deep zone of seasonably strong southwesterly flow from
GA/Carolinas into New England. Visible satellite imagery shows
mostly clear skies in this corridor, where temperatures will climb
into the 90s and dewpoints will be near 70F. This will yield a
region of steep low-level lapse rates and ample CAPE for afternoon
thunderstorm development. Winds aloft will be stronger than
yesterday, and the proximity to the upper trough axis suggests
greater coverage of storms. This should result in a more active
convective day with several clusters of storms capable of damaging
wind gusts through the afternoon and early evening.
