SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0752 PM CDT Thu Aug 08 2024
Valid 090100Z - 091200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE MID ATLANTIC...
...SUMMARY...
An isolated tornado threat will continue tonight across parts of the
Mid Atlantic. Strong thunderstorm wind gusts may affect parts of
Utah and Arizona.
...Mid Atlantic...
Tropical Depression Debby will continue to move northward across
west-central North Carolina this evening and into southern Virginia
tonight. The main rainband associated with Debby is located from
western and northern Virginia into Maryland. Corridors with more
discrete convection are located across southern Virginia and eastern
North Carolina. These three convective areas are located to the
north and east of Debby's center, where the RAP suggests that 850 mb
flow is generally in the 40 to 50 knot range. The WSR-88D VWP at
Richmond, Virginia is sampling the stronger flow, with about 50
knots at 2 km. This is contributing to 0-3 km storm-relative
helicity of 450 to 500 m2/s2, which will continue to support a
tornado threat with the discrete or semi-discrete storms that
develop within this strong low-level flow. The potential for
tornadoes could continue into the late evening or early overnight
period, as Debby moves into southern Virginia.
...Desert Southwest...
Scattered to widely scattered monsoon thunderstorms are ongoing
across much of the Desert Southwest early this evening. Surface
dewpoints across west-central Arizona and southern Utah are in the
50s and lower 60 F, which is contributing to weak instability. In
spite of this, low-level lapse rates are still steep in some areas.
This is evident on RAP forecast soundings, which maintain 0-3 km
lapse rates in the 7 to 8 C/km range across some of the region
through mid to late evening. For this reason, a few of the stronger
storms could produce marginally severe wind gusts.

URGENT - IMMEDIATE BROADCAST REQUESTED
Tornado Watch Number 615
NWS Storm Prediction Center Norman OK
635 PM EDT Thu Aug 8 2024
The NWS Storm Prediction Center has issued a
* Tornado Watch for portions of
District Of Columbia
Maryland
Eastern North Carolina
Central and eastern Virginia
The eastern West Virginia Panhandle
Coastal Waters
* Effective this Thursday night and Friday morning from 635 PM
until 700 AM EDT.
* Primary threats include...
A few tornadoes possible
SUMMARY...Convective bands with embedded supercells and the
potential for a few tornadoes will persist overnight and spread
northward from North Carolina into Virginia/Maryland with the
remnants of tropical cyclone Debby.
The tornado watch area is approximately along and 70 statute miles
east and west of a line from 30 miles east northeast of Martinsburg
WV to 35 miles east of Goldsboro NC. For a complete depiction of the
watch see the associated watch outline update (WOUS64 KWNS WOU5).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Tornado Watch means conditions are favorable for
tornadoes and 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.
&&
OTHER WATCH INFORMATION...This tornado watch replaces tornado
watch number 614. Watch number 614 will not be in effect after
635 PM EDT.
AVIATION...Tornadoes and a few severe thunderstorms with hail
surface and aloft to 0.5 inches. Extreme turbulence and surface wind
gusts to 50 knots. A few cumulonimbi with maximum tops to 500. Mean
storm motion vector 17035.

Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0424 PM CDT Thu Aug 08 2024
Valid 101200Z - 161200Z
A mid-level longwave trough is expected to amplify over the
northwestern CONUS through the period. Various shortwave troughs
around the periphery of this longwave trough may provide a focus for
fire weather concerns over the weekend through early next week.
...D3/Saturday...
A shortwave trough traversing the flow on Saturday may provide lift
for thunderstorm activity across parts of the northern Rockies with
precipitable water in the 0.5-0.75 inch range. Fuels in this region
have received relatively little rain recently, and so should be
receptive to new ignitions. Therefore, a 10% Isolated Dry Thunder
area was added here to reflect the dry lightning risk. Farther west
across portions of southern Idaho and northeastern Nevada, a 40%
Critical highlight has been maintained with low RH and a corridor of
strong surface winds.
...D4/Sunday through D6/Tuesday...
Another shortwave trough embedded in the flow may provide corridors
for strong winds in the presence of generally low RH and receptive
fuels across much of the Great Basin region Sunday through Tuesday.
The highest confidence for this is on D5/Monday, and a 40% Critical
highlight has been maintained across portions of eastern Nevada to
reflect this. Additional highlights may need to be introduced for
Sunday and/or Tuesday in subsequent outlooks if confidence in
Elevated or Critical fire conditions increases.

have received relatively little rain recently, and so should be
receptive to new ignitions. Therefore, a 10% Isolated Dry Thunder
area was added here to reflect the dry lightning risk. Farther west
across portions of southern Idaho and northeastern Nevada, a 40%
Critical highlight has been maintained with low RH and a corridor of
strong surface winds.
...D4/Sunday through D6/Tuesday...
Another shortwave trough embedded in the flow may provide corridors
for strong winds in the presence of generally low RH and receptive
fuels across much of the Great Basin region Sunday through Tuesday.
The highest confidence for this is on D5/Monday, and a 40% Critical
highlight has been maintained across portions of eastern Nevada to
reflect this. Additional highlights may need to be introduced for
Sunday and/or Tuesday in subsequent outlooks if confidence in
Elevated or Critical fire conditions increases.

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0424 PM CDT Thu Aug 08 2024
Valid 101200Z - 161200Z
A mid-level longwave trough is expected to amplify over the
northwestern CONUS through the period. Various shortwave troughs
around the periphery of this longwave trough may provide a focus for
fire weather concerns over the weekend through early next week.
...D3/Saturday...
A shortwave trough traversing the flow on Saturday may provide lift
for thunderstorm activity across parts of the northern Rockies with
precipitable water in the 0.5-0.75 inch range. Fuels in this region
have received relatively little rain recently, and so should be
receptive to new ignitions. Therefore, a 10% Isolated Dry Thunder
area was added here to reflect the dry lightning risk. Farther west
across portions of southern Idaho and northeastern Nevada, a 40%
Critical highlight has been maintained with low RH and a corridor of
strong surface winds.
...D4/Sunday through D6/Tuesday...
Another shortwave trough embedded in the flow may provide corridors
for strong winds in the presence of generally low RH and receptive
fuels across much of the Great Basin region Sunday through Tuesday.
The highest confidence for this is on D5/Monday, and a 40% Critical
highlight has been maintained across portions of eastern Nevada to
reflect this. Additional highlights may need to be introduced for
Sunday and/or Tuesday in subsequent outlooks if confidence in
Elevated or Critical fire conditions increases.
