DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1220 PM CDT WED APR 08 2026
VALID 091200Z - 101200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FROM NORTHEAST
KANSAS INTO SOUTHEAST NEBRASKA AND NORTHWEST MISSOURI...
..SUMMARY
AREAS OF HAIL AND STRONG WIND GUSTS ARE EXPECTED THURSDAY AFTERNOON
AND EVENING IN PARTS OF THE LOWER TO MID MISSOURI VALLEY WESTWARD
INTO KANSAS. LOCALLY VERY LARGE HAIL IS POSSIBLE.
..SYNOPSIS
AN AREA OF CYCLONIC FLOW ALOFT WILL EXIST FROM CENTRAL INTO EASTERN
CANADA, WITH VARIOUS WAVES ROTATING FROM THE NORTHERN PLAINS ACROSS
THE GREAT LAKES. THE SOUTHERN PERIPHERY OF THE STRONGER WINDS ALOFT
WILL EXTEND ACROSS MUCH OF THE NORTHERN PLAINS AND THE MIDWEST, WITH
30 KT 500 MB WINDS AS FAR SOUTH AS NORTHERN KS AND MO.
AT THE SURFACE, A WARM FRONT WILL LIFT NORTH ACROSS NORTHERN KS AND
MO DURING THE DAY, WITH 50S F DEWPOINTS SPREADING NORTH WITH GUSTY
SOUTH WINDS. AS A SHORTWAVE DISTURBANCE MOVES INTO THE NORTHERN
PLAINS LATE, A SURGE OF HIGH PRESSURE WILL PUSH THIS BOUNDARY SOUTH
AS A COLD FRONT AFTER 00Z, EXTENDING FROM SOUTHWEST KS INTO CENTRAL
MO AND IL BY 12Z FRIDAY. SCATTERED STRONG TO SEVERE STORMS WILL BE
MOST LIKELY ALONG THIS EAST-WEST FRONT, WITH MORE ISOLATED ACTIVITY
FROM WESTERN KS INTO THE TX PANHANDLE ALONG A DRYLINE.
.CENTRAL PLAINS
STORMS ARE EXPECTED TO DEVELOP RELATIVELY EARLY, PERHAPS AROUND 18Z
OVER NORTHEAST KS INTO SOUTHEAST NE AS WARM/MOISTENING AIR FROM THE
SOUTH INTERACTS WITH THE WARM FRONT. STRONG HEATING SOUTH OF THE
BOUNDARY WILL RESULT IN STEEP LOW-LEVEL LAPSE RATES, WHILE THE
INCREASING THETA-E RISES NEAR THE BOUNDARY AND BENEATH COLD MIDLEVEL
TEMPERATURES. THE COLD PROFILES ALOFT ALONG WITH 40 KT EFFECTIVE
DEEP-LAYER SHEAR WILL FAVOR HAIL PRODUCTION, WITH PERHAPS ISOLATED
VERY LARGE HAIL.
AS HEATING PEAKS DURING THE LATER AFTERNOON, ADDITIONAL CELLS ARE
EXPECTED EXTENDING SOUTHWESTWARD INTO NORTH-CENTRAL KS. THOUGH
DEWPOINTS WILL ONLY BE IN THE 50S F, SLOW-MOVING SUPERCELLS WILL BE
POSSIBLE, AGAIN WITH VERY LARGE HAIL.
WITH WEST TO NORTHWEST WINDS ALOFT, ALL THESE STORMS MAY EVENTUALLY
MERGE INTO THE EVENING, PROPAGATING SOUTHEASTWARD ACROSS MUCH OF
EASTERN KS INTO NORTHWEST MO. THE WARM BOUNDARY LAYER, COMBINED WITH
COLD DOWNDRAFT MATERIAL, WILL LIKELY SUPPORT SCATTERED DAMAGING
GUSTS.
