800 PM EDT Tue Jul 28 2026
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
North Georgia
* Effective this Tuesday night and Wednesday morning from 800 PM
until 100 AM EDT.
* Primary threats include...
Scattered damaging wind gusts to 65 mph possible
Isolated large hail events to 1 inch in diameter possible
SUMMARY...Widely scattered strong to severe thunderstorms will
likely move into north Georgia through this evening. A couple of
the stronger thunderstorms will be capable of a threat for damaging
gusts (55 to 65 mph) and perhaps isolated hail to 1 inch in
diameter.
The severe thunderstorm watch area is approximately along and 50
statute miles east and west of a line from 20 miles northeast of
Chattanooga TN to 105 miles southeast of Chattanooga TN. For a
complete depiction of the watch see the associated watch outline
update (WOUS64 KWNS WOU1).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
Persons in these areas should be on the lookout for threatening
weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.

Severe Thunderstorm Watch Number 530
NWS Storm Prediction Center Norman OK
650 PM EDT Tue Jul 28 2026
The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Far Northeast Georgia
Central and Southern North Carolina
Western into Northeast South Carolina
* Effective this Tuesday night and Wednesday morning from 650 PM
until 100 AM EDT.
* Primary threats include...
Scattered damaging wind gusts to 70 mph likely
Isolated large hail events to 1.5 inches in diameter possible
A tornado or two possible
SUMMARY...A broken cluster of severe thunderstorms will move
southeast into the Watch area this evening. A few of the stronger
thunderstorms will be supercells capable mainly of a wind damage
threat, but isolated large hail and perhaps a tornado are possible
with these storms through the early evening. As storm outflow
coalesces later this evening and this activity pushes southeast, the
severe risk will transition to primarily damaging gusts.
The severe thunderstorm watch area is approximately along and 55
statute miles either side of a line from 15 miles southwest of
Anderson SC to 20 miles southeast of Rocky Mount NC. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU0).

MD 1793 CONCERNING SEVERE THUNDERSTORM WATCH 527...530... FOR PARTS OF EASTERN NC/VA INTO THE DELMARVA REGION
Mesoscale Discussion 1793
NWS Storm Prediction Center Norman OK
0805 PM CDT Tue Jul 28 2026
Areas affected...Parts of eastern NC/VA into the Delmarva region
Concerning...Severe Thunderstorm Watch 527...530...
Valid 290105Z - 290230Z
The severe weather threat for Severe Thunderstorm Watch 527, 530
continues.
SUMMARY...A threat for damaging wind, marginally severe hail, and
possibly a tornado will continue into late evening.
DISCUSSION...Scattered strong to locally severe storms are ongoing
this evening from across parts of central/eastern NC/VA. The 00Z GSO
and MHX soundings depict a favorable environment for organized
storms, with rich boundary-layer moisture, MLCAPE in excess of 2500
J/kg, and sufficient deep-layer shear. Short-term guidance and area
VWPs depict increasing flow in the lowest 3 km, with associated
low-level theta-e advection potentially supporting an increase in
storm coverage from eastern NC into far southeast VA with time this
evening.
Occasional supercells will continue to be possible into late
evening, with an attendant threat of damaging wind, marginal hail,
and possibly a tornado. Increasing storm coverage may result in some
increase in wind-damage potential with time, with enlarging
low-level hodographs continuing to support some tornado potential,
if surface-based convection can be maintained.

...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE MID-ATLANTIC...CAROLINAS AND SOUTHERN APPALACHIANS...
...SUMMARY...
Thunderstorms capable of severe wind gusts and possibly a tornado or
two are expected this evening from parts of the Mid-Atlantic
southward into the Carolinas and far northeastern Georgia. A few
severe wind gusts may also occur early this evening in parts of the
central High Plains.
...Mid-Atlantic/Carolinas/Northeastern Georgia...
Water vapor imagery currently shows a mid-level trough extending
southward from the lower Great Lakes into the Mid-Atlantic and
Carolinas. At the surface, a 1001 mb low is located over Maryland
with a cold front extending southwestward from the near the low into
the southern Appalachians. Moist air is present ahead of the front
with surface dewpoints in the 70s F. Scattered strong to severe
storms are ongoing across this moist airmass from Delaware southward
into eastern Virginia, central North Carolina and far northeastern
Georgia.
Along this corridor, the RAP shows an axis of moderate instability,
where MLCAPE is currently estimated to be in the 1500 to 3000 J/kg
range. Along and near the instability axis, WSR-88D VWPs from
Moorehead City, North Carolina west-southwestward into far northeast
Georgia have 0-6 km shear near 30 knots and 0-3 km storm-relative
helicity around 200 m2/s2. This environment will continue to support
a potential for supercells with an isolated tornado threat. This
threat should persist for another hour or two. In addition, RAP
forecast soundings near the instability axis have precipitable water
values around 2 inches, suggesting that the more organized line
segments could produce wet downbursts capable of severe gusts.
...Central High Plains...
A mid-level ridge is currently located over the central Rockies,
according to water vapor imagery. A subtle shortwave trough appears
to be moving through the ridge across central Colorado. Ahead of
this feature, large-scale ascent is supporting a broken line of
strong to severe storms from southwest Nebraska into far eastern
Colorado. The RAP currently has an axis of strong instability
analyzed from far southern Nebraska westward into far northeast
Colorado, along which MLCAPE is estimated in the 2000 to 4000 J/kg
range. As the storms move eastward into the strong instability over
the couple of hours, isolated severe wind gusts and hail will be
possible.

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0438 PM CDT Tue Jul 28 2026
Valid 301200Z - 051200Z
...Synopsis...
Upper-level troughing is forecast to continue across portions of the
Pacific Northwest through much of the workweek, with the main
upper-level low remaining offshore. On Day 3/Thursday, a strong and
well-defined mid-level shortwave will rotate through the base of the
trough and over the region within southwest flow aloft. This feature
will promote thunderstorm chances with minimal precipitation across
the Northern Rockies amid a receptive fuelscape. Thereafter,
long-range ensemble guidance continues to suggest that the
aforementioned upper-level low will move onshore this weekend,
yielding dry and breezy conditions across the Northwest and Northern
Rockies. Early next week, model guidance begins to differ in the
progression of the overall upper pattern, with some solutions
depicting a ridge to rebuild over the western CONUS, while others
portray weak northwesterly flow across the Pacific Northwest.
Regardless, trends will continue to be monitored.
...Northwestern US...
Wet/dry thunderstorm chances return on Day 3/Thursday as a shortwave
trough impinges upon the region. Ample instability, a dry boundary
layer, and sufficient mid-level moisture support 10% dry
thunderstorm probabilities. A lingering dry boundary layer and warm
daytime temperatures are expected to increase fuel receptivity
(forecast ERCs approaching the 95th percentile), enhancing concerns
for new lightning ignitions. Gusty winds and a dry airmass return to
the Pacific Northwest this weekend as the offshore trough moves
inland, with greater potential for critical fire conditions to
materialize -- especially where strong winds/low RH overlap areas
where preceding days of thunderstorms may result in holdover
ignitions. As such, 40% Critical probabilities have been maintained
on Days 5-6/Saturday-Sunday.
...Southern High Plains...
Hot, dry, and breezy conditions are likely across portions of the
southern High Plains on Day 3/Thursday; however, fuels guidance
suggests the fuelscape remains mostly mixed, precluding the
introduction of probabilities. Nevertheless, daytime RH values of
15-20% and sustained southerly winds of 15-20 mph should promote
locally elevated fire weather concerns where pockets of dry fuels
exist.
