SPC MD 2042MD 2042 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PORTIONS OF SOUTHERN MISSOURI INTO FAR NORTHERN ARKANSAS 
Mesoscale Discussion 2042
NWS Storm Prediction Center Norman OK
0300 PM CDT Wed Aug 19 2026
Areas affected...Portions of southern Missouri into far northern
Arkansas
Concerning...Severe potential...Watch possible
Valid 192000Z - 192200Z
Probability of Watch Issuance...60 percent
SUMMARY...The threat for damaging winds, isolated large hail, and
perhaps a tornado or two will eventually increase within parts of
the Ozarks this afternoon. Timing of storm initiation is not
certain, but a watch may eventually be needed.
DISCUSSION...As cloud cover from earlier convection has cleared,
cumulus agitation is noted in southwest Missouri along a
quasi-dryline-like feature. Temperatures to the southwest of this
boundary have risen into the low 100s F. Destabilization has
occurred to the east of the boundary as well, though some MLCIN is
still evident. 35-40 kt of effective shear across this boundary will
promote eventual supercell development. Given the majority of the
shear exists within the lower half of the troposphere, it is not
certain how long a supercell mode will be maintained. Damaging
winds, isolated large hail, and perhaps a tornado or two will be
possible. A very modest increase in low-level flow during the
evening will mean a modest increase in tornado potential should
supercell modes exist beyond 00Z. A watch is possible this
afternoon, though timing remains uncertain.

SPC MD 2043MD 2043 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR PARTS OF EAST CENTRAL AND SOUTHEASTERN ARIZONA 
Mesoscale Discussion 2043
NWS Storm Prediction Center Norman OK
0308 PM CDT Wed Aug 19 2026
Areas affected...parts of east central and southeastern Arizona
Concerning...Severe potential...Watch possible
Valid 192008Z - 192245Z
Probability of Watch Issuance...40 percent
SUMMARY...Thunderstorm activity will continue to slowly increase and
spread westward off the higher terrain through 2-4 PM MST. A severe
weather watch may be needed at some point, once storms begin to
consolidate into an evolving cluster, but this may not be until
later this evening.
DISCUSSION...Substantive destabilization is ongoing across much of
central and southern Arizona, within a seasonably moist air mass
boosted by a recent surge from the Gulf of California. Latest
objective analysis indicates that strongest potential instability
has become focused to immediate southwest and west of the higher
terrain of east central into southeastern Arizona, where inhibition
has been eroding most appreciably. As this continues over the next
few hours, a slow propagation off the higher terrain straddling the
southern Arizona/New Mexico border may commence by 21-23Z, with
strong downbursts posing increasing potential for strong to severe
surface gusts within a strongly heated and deep mixed
boundary-layer. Increasing thunderstorm development closer to the
southeastern Arizona international border may also begin to impact
the Tucson vicinity.

SPC MD 2044MD 2044 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR NORTHWEST KANSAS 
Mesoscale Discussion 2044
NWS Storm Prediction Center Norman OK
0342 PM CDT Wed Aug 19 2026
Areas affected...Northwest Kansas
Concerning...Severe potential...Watch unlikely
Valid 192042Z - 192245Z
Probability of Watch Issuance...5 percent
SUMMARY...An isolated supercell appears possible based on recent
satellite trends. Isolated large hail and severe winds are possible
should a storm develop. A watch is not likely.
DISCUSSION...An area of agitated cumulus has developed in northwest
Kansas over the last hour along a weak surface cold front. Very weak
ascent aloft from a glancing shortwave trough in the central Plains
could allow an isolated supercell to develop. Visible satellite
trends and some recent CAM guidance would suggest storm initiation
is probable, though not certain. The environment would support
isolated large hail and severe winds. Given the lack of greater
upper-level support, coverage and duration of severe intensity will
likely be limited.

SPC MD 2045MD 2045 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PORTIONS OF NORTHERN AND CENTRAL ILLINOIS...CENTRAL AND NORTHERN INDIANA...WESTERN OHIO 
Mesoscale Discussion 2045
NWS Storm Prediction Center Norman OK
0452 PM CDT Wed Aug 19 2026
Areas affected...portions of northern and central Illinois...central
and northern Indiana...western Ohio
Concerning...Severe potential...Watch unlikely
Valid 192152Z - 192315Z
Probability of Watch Issuance...20 percent
SUMMARY...Isolated severe storms may develop along a west-to-east
oriented boundary through the remainder of the afternoon.
DISCUSSION...Scattered thunderstorms have been increasing in
intensity along a diffuse west-to-east oriented boundary extending
from central and northern Illinois into western Ohio. Along this
boundary, over 1000 J/kg MLCAPE is in place, along with substantial
0-3 km CAPE (150-175 J/kg). Furthermore, an 80 kt 300 mb jet streak
is overspreading the OH Valley, contributing to 50+ kts of effective
bulk shear (mainly speed shear in the mid to upper levels per RAP
forecast soundings). Given these conditions, the current thinking is
that a few of the stronger storms along this baroclinic boundary may
become transient supercellular, capable of producing a couple
instances of severe wind/hail or even a brief tornado.

SPC Day 3-8 Fire Weather Outlook

SPC Day 3-8 Fire Weather OutlookSPC Day 3-8 Fire Weather Outlook 
Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0450 PM CDT Wed Aug 19 2026
Valid 211200Z - 271200Z
...Synopsis...
An established ridge over the Intermountain West will amplify and
the pressure gradient will continue to tighten on Day 3/Friday as a
trough approaches the west CONUS coast. A mid-level low pressure
system will near the Pacific Northwest coast on Day 3/Friday as the
upper-level jet max peaks over southern/central OR. This will
provide widespread lift to portions of the Cascade Mountains and
then much of central/eastern WA under the left exit region of the
jet streak on the evening/night of Day 3/Friday. The trough will
begin to lift northeastward as it becomes slightly negatively-tilted
going into Day 4/Saturday. High pressure remains in place over much
of the southwestern half of the CONUS with shortwave trough passages
periodically moving across the crest of the high through the
northern states. While slight differences in timing of the
aforementioned trough remain, the overall pattern evolution remains
similar amongst various ensemble forecast guidance. As we turn the
corner toward next week, the ridge broadens and builds over the
Intermountain West once again. Forecast certainty in any particular
solution decreases thereafter given greater ensemble spread.
...Pacific Northwest/Northern California/Great Basin...
The Pacific Northwest and immediately neighboring areas of northern
California and the Great Basin will remain the foci through at least
the first half of the extended forecast. Starting on Day 3/Friday
and continuing through Day 4/Saturday, expect multiple consecutive
days of gusty southwesterly winds combined with warm and dry weather
as the aforementioned large trough approaches from the west.
Increasing above-normal temperatures through Day 3/Friday will give
way to cooler conditions as the trough approaches and moves onshore
Day 4/Saturday. Given the jet aloft and surface conditions that
would support deep daytime mixing, a favorable pattern remains in
place for dry and breezy weather to overlap very dry fuels across
northeastern CA, southern OR, and northwestern NV. 40% Critical
probabilities were maintained on Day 3/Friday through Day 4/Saturday
along with a widespread 10% probability of Dry Thunderstorms over
much of the Pacific Northwest and the nearby northern Rockies.
Additionally, where winds appear strongest (sustained at 20-25 mph
from the southwest) over the tri-state CA, OR, NV area, 70% Critical
probabilities were maintained on Day 4/Saturday. While a
thunderstorm or two favoring the higher terrain of the Cascades (and
pyro-aided convection amid initially hot, dry, and windy surface
conditions) can't be ruled out on the afternoon of Day 3/Friday, the
best convective potential will occur starting around 06Z on Saturday
(Friday night) as the jet max approaches. This pattern of
aforementioned upper-level support, limited but adequate
(precipitable water values near 0.5-0.7") moisture, fast-moving
(25-35 mph) storms, and dry fuels (ERCs near the 80-95th percentile)
remains in place on Day 4/Saturday. With minimal precipitation
expected from the previous day, an area of 10% Dry Thunderstorm risk
was introduced over portions of the northern Pacific Northwest
region and the nearby far western extent of the northern Rockies
region.
...Southern Plains...
On Day 5/Sunday and Day 6/Monday, a cold front will move across the
southern Plains, increasing fire weather risk in southwesterly flow
ahead of the front as it progresses southeastward. Current ensemble
forecast guidance suggests sustained 10-20 mph south to
southwesterly winds will combine with afternoon RHs near 15-20%
across the TX/OK Panhandles and surrounding areas with critically
dry fuels.
...Northern Plains...
Evolution of the post-frontal northwesterly winds over the northern
High Plains remains a concern on Day 5/Sunday. Across much of the
central MT, sustained northwesterly winds of 10-20 mph will occur.
Some forecast guidance shows these strong and gusty winds extending
even farther across eastern MT. This area will be watched closely
with future outlook issuances.

SPC MD 2040MD 2040 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR PARTS OF EASTERN MISSISSIPPI INTO SOUTHERN ALABAMA 
Mesoscale Discussion 2040
NWS Storm Prediction Center Norman OK
0229 PM CDT Wed Aug 19 2026
Areas affected...parts of eastern Mississippi into southern Alabama
Concerning...Severe potential...Watch unlikely
Valid 191929Z - 192200Z
Probability of Watch Issuance...20 percent
SUMMARY...Increasing thunderstorm development is likely through 5-7
PM CDT, accompanied by localized damaging downbursts and at least a
bit more widespread strong, but generally sub-severe, wind gusts.
Due to the disorganized and generally localized nature of the more
intense gusts, a severe weather watch is not currently anticipated,
but trends will be monitored.
DISCUSSION...Forcing for thunderstorm development remains unclear,
but perhaps aided by weak near-surface warm advection, initiation of
widely scattered thunderstorms appears underway within a broadly
confluent low-level regime across eastern Mississippi into southern
Alabama. This is occurring in the presence of light (10 kt or less)
north-northwesterly deep-layer mean flow, but thermodynamic profiles
characterized by a strongly heated, seasonably high moisture content
boundary layer, with steep lower/mid-tropospheric lapse rates of
potential wet-bulb temperature.
Heavy precipitation loading, coupled with evaporative cooling, may
contribute to localized damaging downbursts in the initially more
widely scattered strongest storms. Gradually,
colliding/intersecting outflow may contribute to increasing
thunderstorm development with continuing potential for strong
surface gusts into early evening.
