Central Illinois
West-Central into Northern Indiana
Western and Central Lower Michigan
Far Northwest Ohio
Lake Michigan
* Effective this Thursday night and Friday morning from 805 PM
until 200 AM EDT.
* Primary threats include...
A few tornadoes and a couple intense tornadoes possible
Widespread damaging winds and isolated significant gusts to 75
mph likely
Isolated large hail events to 1.5 inches in diameter possible
SUMMARY...A mix of supercells and severe bows will move into the
Watch area this evening. A risk for a few tornadoes, including the
possibility for a strong tornado is forecast with the more intense
supercells and embedded mesovortices within the stronger bows.
Widespread damaging winds (60 to 75 mph) will likely focus with the
bowing segments as they rapidly move east-northeastward this evening
into the early overnight.
The tornado watch area is approximately along and 80 statute miles
east and west of a line from 35 miles west northwest of Saginaw MI
to 20 miles west of Terre Haute IN. For a complete depiction of the
watch see the associated watch outline update (WOUS64 KWNS WOU8).

Eastern Pennsylvania
Eastern Virginia
Coastal Waters
* Effective this Thursday night from 715 PM until Midnight EDT.
* Primary threats include...
Scattered damaging wind gusts to 65 mph possible
Isolated large hail events to 1 inch in diameter possible
SUMMARY...A squall line will continue east into the Watch area this
evening and likely reach the coast tonight. Broken bands of
thunderstorms containing stronger thunderstorm cores and small-scale
bows embedded within the larger-scale squall line will probably
focus the threat for strong to severe gusts capable of wind damage.

MD 1103 CONCERNING TORNADO WATCH 318... FOR CENTRAL INTO NORTH-CENTRAL INDIANA
Mesoscale Discussion 1103
NWS Storm Prediction Center Norman OK
0819 PM CDT Thu Jun 11 2026
Areas affected...central into north-central Indiana
Concerning...Tornado Watch 318...
Valid 120119Z - 120245Z
The severe weather threat for Tornado Watch 318 continues.
SUMMARY...A swath of 65 to 85 mph winds are expected across central
to north-central Indiana this evening.
DISCUSSION...A mature bow-echo has developed across east-central
Illinois with a strong rear-inflow jet. This bow has left a large
swath of wind damage over the past hour including a measured 68 mph
wind gust in Champaign, IL. 65 to 85 mph winds are expected to
continue across a relatively wide swath as it moves east into a very
unstable environment through the evening. Some embedded QLCS
tornadoes will also be possible, especially north of the apex of the
bow, but the strong measured wind gusts will be the primary threat.

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0800 PM CDT Thu Jun 11 2026
Valid 120100Z - 121200Z
...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE MIDWEST/GREAT LAKES...
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR PARTS OF THE
MID ATLANTIC...
...SUMMARY...
Severe thunderstorms will continue this evening across parts of the
Midwest and Great Lakes region. This includes the potential for
tornadoes (possibly strong), widespread/intense damaging winds (some
75+ mph), and isolated hail.
...Parts of the Midwest/Great Lakes...
A rather volatile environment remains in place this evening across
parts of IL/IN and southwest Lower MI, especially in the vicinity of
a modified outflow across northern IL/IN. Rich low-level moisture,
moderate to strong buoyancy, and strong low-level shear/SRH will
continue to support all severe hazards through much of the evening.
Convection has largely taken on a linear or cluster mode, with an
attendant threat of severe/damaging gusts and line-embedded
tornadoes. Any discrete cells that can be maintained within or ahead
of ongoing convection will continue to pose a conditional
strong-tornado threat, along with isolated hail potential. See MCD
1101 and MCD 1102 for more information regarding the short-term
threat in this area.
Increasing CINH and decreasing MLCAPE with eastward extent should
eventually result in a weakening trend, though an organized severe
threat may reach parts of southeast MI and western OH later tonight.
...OK/TX into MO/northern AR...
Scattered strong to locally severe storms are ongoing from parts of
western/central OK into MO, generally along or just behind a
southward moving cold front. Moderate to strong buoyancy and
deep-layer shear of around 25-35 kt near the front will continue to
support occasional storm organization and a continued threat of hail
and localized severe gusts, though convection may increasingly
become undercut by the front with time. An isolated severe threat
may eventually spread toward the Red River into western/northern AR
late tonight.
...Mid Atlantic vicinity...
Loosely organized storm clusters with a history of producing wind
damage are approaching the Mid Atlantic coast this evening. While
deep-layer shear will continue to be modest at best, a very
warm/moist boundary layer and moderate buoyancy will continue to
support potential for strong to locally severe gusts and scattered
wind damage, before convection weakens and/or moves offshore later
tonight.

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0448 PM CDT Thu Jun 11 2026
Valid 131200Z - 191200Z
...Synopsis...
Broad upper-level troughing will remain anchored over the
Manitoba/Ontario region on Day 3/Saturday as an upper-level ridge
builds over the West Coast. Early next week, a shortwave trough is
forecast to dig southward around the base of this persistent
Canadian trough, tracking across the northern Rockies around Day
4/Sunday. The upper-level ridge is expected to break down early to
mid-week as an upper-level jet max strengthens and progresses ahead
of an incoming northern Pacific trough. This secondary trough is
projected to move onshore into the Pacific Northwest by mid-to-late
next week, subsequently shifting the axis of the ridge eastward over
the Great Plains.
...Day 3/Saturday...
A narrow, amplified upper-level ridge will stretch across the
western CONUS on Day 3/Saturday, while a subtle mid-level shortwave
migrates across the Southwest. Simultaneously, a plume of mid-level
moisture advecting northward from the Baja Peninsula will promote
convective potential, primarily centered over the southern Great
Basin. Given deep, dry antecedent fuel conditions resulting from
consecutive days of hot, dry, and breezy weather, dry thunderstorms
will pose an ignition concern across northern AZ and southern UT. A
10% probability of dry thunderstorms continues for this area.
Further spatial modifications to this risk area remain likely in
upcoming outlook cycles as additional forecast guidance becomes
available.
...Day 6/Tuesday through Day 7/Wednesday...
Looking deeper into next week, the wholesale breakdown of the
western ridge is expected to escalate fire weather concerns across
the Intermountain West as the jet strengthens and gives way to
another trough later next week. But first, at least 2-3 days of well
above normal surface temperatures will occur under the established
ridge. Daily record high temperatures could be met or exceeded in
portions of the Pacific Northwest as this anomalous, but
short-lived, heat wave effectively dries dead fuels over much of the
western CONUS - significantly so over the Pacific Northwest. As the
ridge dampens and begins to slide eastward, expect winds to
strengthen amid the pre-existing very warm and dry conditions. Thus,
40% Critical probabilities have been introduced over portions of the
Great Basin and Southwest on Day 6/Tuesday and Day 7/Wednesday.
These areas will likely require expansion when the areal extent of
the strongest winds becomes more clear.
