NWS STORM PREDICTION CENTER NORMAN OK
1256 AM CDT TUE AUG 18 2026
VALID 181200Z - 191200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE CENTRAL PLAINS AND LOWER MISSOURI VALLEY...
...SUMMARY...
THUNDERSTORMS WITH SEVERE WIND GUSTS AND ISOLATED LARGE HAIL WILL BE
POSSIBLE THIS AFTERNOON AND EVENING FROM THE CENTRAL PLAINS INTO THE
LOWER MISSOURI VALLEY. ISOLATED SEVERE GUSTS AND HAIL WILL ALSO BE
POSSIBLE FROM THE NORTHERN HIGH PLAINS EASTWARD INTO THE MIDWEST AND
SOUTHERN GREAT LAKES.
...CENTRAL AND NORTHERN PLAINS...
AT MID-LEVELS, A BROAD CYCLONIC FLOW PATTERN WILL BE IN PLACE OVER
THE NORTHERN U.S. A SHORTWAVE TROUGH WILL MOVE ACROSS THE CENTRAL
AND NORTHERN PLAINS. AT THE SURFACE, A COLD FRONT WILL ADVANCE
SOUTHWARD INTO NEBRASKA BY AFTERNOON. TO THE SOUTH OF THE FRONT, AN
OUTFLOW BOUNDARY FROM MORNING CONVECTION WILL MOVE SOUTHWARD INTO
NORTHERN KANSAS. A MOIST AIRMASS WILL EXIST BETWEEN THE TWO
BOUNDARIES WITH SURFACE DEWPOINTS IN THE UPPER 60S TO LOWER 70S F.
WITHIN THE MOIST AIR, MODERATE TO STRONG INSTABILITY WILL DEVELOP BY
AFTERNOON. THE OUTFLOW BOUNDARY WILL BE A FOCUS FOR CONVECTIVE
INITIATION DURING THE DAY, WHILE ADDITIONAL STORMS ARE EXPECTED TO
DEVELOP FURTHER WEST ACROSS THE CENTRAL HIGH PLAINS IN THE LATE
AFTERNOON. INCREASING CONVECTIVE COVERAGE DURING THE EARLY EVENING
SHOULD RESULT IN THE DEVELOPMENT OF A LINE SEGMENT.
RAP FORECAST SOUNDINGS AT 00Z FROM SALINA TO KANSAS CITY HAVE MLCAPE
IN THE 1500 TO 2500 J/KG RANGE WITH 0-6 KM SHEAR AROUND 40 KNOTS.
700-500 MB LAPSE RATES ARE FORECAST TO BE IN THE 7 TO 8 C/KM RANGE.
THIS ENVIRONMENT WILL SUPPORT SUPERCELLS WITH ISOLATED LARGE HAIL.
THE LARGE HAIL THREAT WILL EXTEND WEST-NORTHWESTWARD INTO SOUTHWEST
NEBRASKA DURING THE LATE AFTERNOON WHERE MID-LEVEL LAPSE RATES WILL
BE STEEPER AND CELLS WILL LIKELY REMAIN DISCRETE. THE GREATEST
WIND-DAMAGE POTENTIAL IS FORECAST FROM NORTHERN AND EASTERN KANSAS
INTO FAR WESTERN MISSOURI, WHERE THE DEVELOPMENT OF AN ORGANIZED
BOWING LINE SEGMENT WILL BE POSSIBLE IN THE EARLY EVENING. WIND
GUSTS ABOVE 75 MPH WILL BE POSSIBLE ALONG THE PATH OF ANY INTENSE
LINE SEGMENT. THE SEVERE THREAT MAY IMPACT PARTS OF LOWER MISSOURI
VALLEY AND OZARKS BY MID TO LATE EVENING.
...MIDWEST/GREAT LAKES...
A MID-LEVEL SHORTWAVE TROUGH WILL MOVE ACROSS THE NORTH-CENTRAL U.S.
TODAY, AS A COLD FRONT ADVANCES SOUTHEASTWARD ACROSS THE MIDWEST AND
GREAT LAKES. TO THE SOUTH OF THE FRONT, SURFACE DEWPOINTS IN THE 60S
F WILL CONTRIBUTE TO MODERATE INSTABILITY ALONG AN
WEST-NORTHWEST-TO-EAST-NORTHEAST AXIS FROM THE MID MISSISSIPPI
VALLEY INTO THE SOUTHERN GREAT LAKES. ISOLATED TO SCATTERED
THUNDERSTORMS APPEAR LIKELY TO FORM ALONG AND SOUTH OF THE FRONT IN
THE LATE AFTERNOON AND EARLY EVENING. MLCAPE IN THE 1000 TO 2000
J/KG RANGE, 0-6 KM SHEAR AROUND 40 KNOTS AND PRECIPITABLE WATER IN
THE 1.7 TO 1.9 INCH RANGE WILL BE FAVORABLE FOR ISOLATED SEVERE
STORMS CAPABLE OF SEVERE WET DOWNBURSTS.
...NORTHERN HIGH PLAINS...
NORTHWESTERLY MID-LEVEL FLOW WILL BE IN PLACE TODAY FROM THE
NORTHERN ROCKIES INTO THE NORTHERN HIGH PLAINS. AT THE SURFACE,
DEWPOINTS ALONG THE MOIST AXIS FROM NORTHEASTERN WYOMING INTO
CENTRAL MONTANA WILL BE AROUND 50 F. AS SURFACE TEMPERATURES WARM
DURING THE DAY, MLCAPE IS EXPECTED TO INCREASE TO AROUND 1000 J/KG
IN PARTS OF THE NORTHERN HIGH PLAINS. THUNDERSTORMS ARE EXPECTED TO
FORM IN THE HIGHER TERRAIN IN THE AFTERNOON, MOVING
EAST-SOUTHEASTWARD INTO THE LOWER ELEVATIONS. DUE TO THE INSTABILITY
AND STEEP LOW TO MID-LEVEL LAPSE RATES, ISOLATED SEVERE WIND GUSTS
WILL BE POSSIBLE WITH THE STRONGER CELLS.

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1246 AM CDT TUE AUG 18 2026
VALID 191200Z - 201200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM SOUTHERN
MISSOURI INTO NORTHERN ARKANSAS...AND INTO SOUTHERN ILLINOIS AND FAR
WESTERN KENTUCKY AND TENNESSEE...
...SUMMARY...
ISOLATED STRONG TO SEVERE THUNDERSTORMS MAY PRODUCE HAIL AND STRONG
TO SEVERE WIND GUSTS FROM THE CENTRAL PLAINS TO THE MID-MISSISSIPPI
VALLEY AND OZARKS. THE GREATEST RISK AREA IS FROM THE OZARKS INTO
THE LOWER OHIO VALLEY WEDNESDAY AFTERNOON AND EVENING.
...SOUTHERN MO...NORTHERN AR...WESTERN KY/TN...SOUTHERN IL...
GRADUAL HEIGHT FALLS WILL OCCUR THROUGHOUT THE PERIOD AS A
LOW-AMPLITUDE SHORTWAVE TROUGH MOVES OUT OF THE PLAINS AND TOWARD
MID MS/OH VALLEYS. EARLY DAY THUNDERSTORMS MAY BE ONGOING FROM MO
INTO THE LOWER OH VALLEY, BUT PERHAPS NOT PARTICULARLY STRONG.
BEHIND THIS INITIAL ACTIVITY, STRONG INSTABILITY WILL REDEVELOP FROM
MO INTO NORTHERN AR, AND WESTERN KY/TN WITH SOUTHWEST LOW-LEVEL
WINDS AND 70S F DEWPOINTS NEAR A SOUTHWARD MOVING FRONT OVER
SOUTHERN MO. PREDICTABILITY IS A BIT LOW FOR THE BOUNDARY POSITION,
BUT STORMS MAY FORM ANYWHERE FROM I-70 SOUTHWARD INTO NORTHERN AR
DURING THE LATE AFTERNOON, MOVING EAST/SOUTHEAST DURING THE EVENING.
CORRIDORS OF DAMAGING WIND AND HAIL WILL BE POSSIBLE, WITH ANY BRIEF
TORNADO CHANCES DEPENDING ON EARLIER OUTFLOWS WHICH MAY ENHANCE
LOW-LEVEL SHEAR.
...CENTRAL AND NORTHERN PLAINS...
A SHORTWAVE TROUGH WILL MOVE FROM THE NORTHERN PLAINS INTO THE MID
MS VALLEY ON WEDNESDAY, WITH 40 KT NORTHWEST FLOW AT 500 MB ACROSS
MUCH OF THE CENTRAL PLAINS. ALTHOUGH A FRONT WILL PUSH SOUTH ACROSS
OK AND THE TX PANHANDLE, LOW-LEVEL MOISTURE WITH 50S TO 60S F
DEWPOINTS WILL REMAIN BENEATH THIS UPPER TROUGH, AND STRONG HEATING
WILL LEAD TO CLUSTERS OF STORMS WITHIN A WEAK SURFACE TROUGH/WIND
SHIFT BY LATE AFTERNOON. FAVORED AREAS WILL BE FROM SD INTO NE WHERE
TEMPERATURES ALOFT WILL BE COLD AND COUNTERACT THE LACK OF LOW-LEVEL
MOISTURE, AND FROM THE FRONT RANGE SOUTHWARD INTO NORTHEAST NM.
SCATTERED HAIL OVER 1.00" OR LOCALLY SEVERE GUSTS WILL BE POSSIBLE
THROUGH EARLY EVENING AS STORMS TRAVEL SOUTHEASTWARD OUT OF THE HIGH
PLAINS AND ACROSS SD, NE AND KS.

NWS STORM PREDICTION CENTER NORMAN OK
0227 AM CDT TUE AUG 18 2026
VALID 201200Z - 211200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
THE NORTHERN PLAINS...AND OVER EASTERN VIRGINIA AND NORTH
CAROLINA...
...SUMMARY...
SCATTERED STRONG TO SEVERE STORMS MAY OCCUR ON THURSDAY FROM
MINNESOTA INTO NEBRASKA AND NORTHERN KANSAS, PRODUCING LARGE HAIL
AND LOCALIZED WIND DAMAGE. SCATTERED STORMS MAY ALSO PRODUCE LOCALLY
SEVERE GUSTS FROM EASTERN VIRGINIA INTO NORTH CAROLINAS.
...NORTHERN PLAINS...
AN UPPER RIDGE WILL BUILD OVER THE WEST ON THURSDAY, WITH TIGHTENING
MIDLEVEL HEIGHT GRADIENT OVER THE NORTHERN PLAINS. THIS WILL RESULT
IN INCREASING WINDS OUT OF THE NORTHWEST, WITH OVER 40 KT AT 500 MB.
AT THE SURFACE, A TROUGH/WIND SHIFT IS FORECAST TO EXTEND ROUGHLY
FROM MN INTO NE, WITH STEEP LAPSE RATES DEVELOPING. STORMS WILL
LIKELY FORM ALONG THIS BOUNDARY DURING THE AFTERNOON, WITH SCATTERED
CELLS PRODUCING LARGE HAIL. SOME PREDICTABILITY ISSUES EXIST AMONGST
MODELS, AND THEREFORE WILL DEFER A CATEGORICAL UPGRADE TO LATER
UPDATES. THE COMBINATION OF 40+ KT OF DEEP LAYER SHEAR, STEEP LAPSE
RATES AND 60S F DEWPOINTS MAY SUPPORT HAIL AT OR ABOVE 2.00"
DIAMETER.
...EASTERN VA AND NC...
A MID/UPPER WAVE WILL CROSS THE APPALACHIANS AS A SURFACE TROUGH
DEVELOPS DURING THE AFTERNOON. THIS WILL BRING MIDLEVEL WINDS OF
30-40 KT ACROSS MD/VA AND INTO NORTHERN NC, AIDING DEEP-LAYER SHEAR
AS WELL AS OVERALL MEAN WIND SPEEDS. AT LEAST ISOLATED SEVERE STORMS
APPEAR POSSIBLE FROM EASTERN VA INTO NC WHERE 70S F DEWPOINTS WILL
SUPPORT MODERATE INSTABILITY, WITH FAVORABLE AFTERNOON TIMING
SUPPORTING LOCALIZED WIND DAMAGE.

NWS STORM PREDICTION CENTER NORMAN OK
0324 AM CDT TUE AUG 18 2026
VALID 211200Z - 261200Z
...DISCUSSION...
FOR THE FRI/D4 TO TUE/D8 PERIOD, AN UPPER RIDGE IS FORECAST TO
EXPAND FROM THE FOUR CORNERS STATES INTO THE SOUTHERN PLAINS, WITH
NORTHWEST FLOW ALOFT OVER THE NORTHERN PLAINS SHIFTING EAST ACROSS
MIDWEST AND INTO THE NORTHEAST.
ON FRI/D4, SCATTERED STORMS MAY OCCUR ACROSS THE CENTRAL PLAINS AND
CORNBELT, WITH AREAS OF MOISTURE AND INSTABILITY BENEATH THE 30-40
KT NORTHWEST FLOW REGIME FAVOR SCATTERED HAIL OR STRONG WIND GUSTS.
PREDICTABILITY IS LOW DUE TO THE LIKELIHOOD OF ONGOING STORMS OR
CONVECTIVE SYSTEMS EARLY IN THE DAY, WHICH MAY AFFECT AIR MASS
QUALITY AND EFFECTIVE BOUNDARY POSITIONING. HOWEVER, THE NE/KS/IA/MO
REGION APPEARS TO BE THE MOST LIKELY AREA FOR AN EVENTUAL RISK AREA.
ALSO ON FRI/D4, STORMS ARE AGAIN EXPECTED OVER PARTS OF THE MID
ATLANTIC TO CAROLINAS, WHERE 25 KT SOUTHWEST FLOW IN THE MIDLEVELS
AND A SURFACE TROUGH WILL SUPPORT SCATTERED STORM CLUSTERS PRODUCING
LOCALLY DAMAGING GUSTS. AREAS OF ONGOING STORMS OR OUTFLOWS FROM THE
PREVIOUS DAY'S CONVECTION MAY HAVE AN IMPACT HERE AS WELL AS FAR AS
THE MOST FAVORABLE ZONES FOR ADDITIONAL SEVERE STORMS.
THERE MAY ALSO BE SOME POTENTIAL ON SAT/D5 TO SUN/D6 OVER PARTS OF
THE MID ATLANTIC AS COOLING ALOFT WITH AN UPPER TROUGH MOVES ACROSS
THE AREA. TIMING OF THIS TROUGH WILL BE CRITICAL, AS WILL THE
MOVEMENT OF THE ASSOCIATED COLD FRONT.

DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1227 AM CDT TUE AUG 18 2026
VALID 181200Z - 191200Z
...SYNOPSIS...
HEIGHTS WITH THE WESTERN RIDGE WILL RISE AGAIN TODAY, WITH WARMING
TEMPERATURES AND DRY CONDITIONS ACROSS MUCH OF THE PACIFIC
NORTHWEST. ALONG THE NORTHERN PERIPHERY OF THE RIDGE, A SHORTWAVE
PASSAGE WILL BRING BREEZY CONDITIONS TO AREAS EAST OF THE CASCADES.
DRY AND BREEZY CONDITIONS WILL ALSO BE POSSIBLE SOUTH OF A FRONTAL
BOUNDARY ACROSS WESTERN OKLAHOMA INTO THE TEXAS PANHANDLE.
...PORTIONS OF THE COLUMBIA BASIN...
A SPLIT FLOW REGIME ALOFT WILL INDUCE WEST-NORTHWESTERLY FLOW OVER
WASHINGTON, AND SOUTHWEST-WESTERLY FLOW OVER OREGON. COMBINED WITH
LEE SURFACE TROUGHING, WIND SPEEDS WILL INCREASE ACROSS THE CASCADE
GAPS. WEST-NORTHWESTERLY SURFACE WINDS OF AROUND 10-15 MPH WILL
ENCOMPASS A BROAD AREA OF THE COLUMBIA BASIN, WITH STRONGER WINDS OF
20-30 MPH WITHIN THE GAPS. AT PEAK HEATING, RELATIVE HUMIDITY VALUES
WILL DECLINE TO AROUND 15-20 PERCENT. BROADLY ELEVATED FIRE WEATHER
CONDITIONS ARE EXPECTED IN THE LEE OF THE CASCADES, WITH LOCALLY
CRITICAL CONDITIONS POSSIBLE.
...SOUTHERN PLAINS...
DROUGHT CONDITIONS ARE PROMINENT ACROSS MUCH OF THE REGION,
EXPANDING FROM THE TEXAS PANHANDLE INTO WESTERN/CENTRAL OKLAHOMA TO
PRODUCE A STRESSED FUEL ENVIRONMENT. BREEZY AND DRY CONDITIONS ARE
EXPECTED NEAR THE SURFACE TROUGH ACROSS THE TEXAS PANHANDLE INTO
WESTERN OKLAHOMA. PROFILES WILL BE DEEPLY MIXED, WITH TEMPERATURES
APPROACHING THE 100S F AGAIN THIS AFTERNOON. THIS WILL SUPPORT
AFTERNOON RELATIVE HUMIDITY VALUES OF 10-15% AMID SOUTHWEST WINDS OF
15-20 MPH, MAINTAINING AN ELEVATED RISK AREA.

1228 AM CDT TUE AUG 18 2026
VALID 191200Z - 201200Z
...NO CRITICAL AREAS...
...SYNOPSIS...
UPPER RIDGING WILL EXPAND FARTHER INTO THE INTERMOUNTAIN WEST ON DAY
2/WEDNESDAY, SUPPORTING HOT AND DRY CONDITIONS AMID GENERALLY
LIGHTER WINDS. DEEPER MONSOONAL MOISTURE WILL REMAIN EMBEDDED WITHIN
THE DESERT SOUTHWEST, BUT RESIDUAL MID-LEVEL MOISTURE IN THE GREAT
BASIN COULD SUPPORT A FEW ISOLATED SHOWERS IN THE HIGHER TERRAIN. IN
THE SOUTHERN PLAINS, A WEAK FRONTAL BOUNDARY WILL SAG INTO THE TEXAS
PANHANDLE AND OKLAHOMA THROUGHOUT THE DAY. MODELS VARY ON THE TIMING
OF THE FRONT, AND PROGRESSION WILL LARGELY DEPEND UPON THUNDERSTORM
OUTFLOW ACROSS SOUTHWESTERN KANSAS ON DAY 1/TUESDAY
EVENING/OVERNIGHT. NEVERTHELESS, A DEEPLY MIXED PROFILE WILL LEAD TO
ANOTHER DAY OF HIGH TEMPERATURES IN THE 100S F AND RH VALUES OF
15-20% AHEAD OF THE FRONT, PROMOTING LOCALLY ELEVATED FIRE WEATHER
CONCERNS AMID A DROUGHT STRESSED FUELSCAPE.
