DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0223 PM CDT SAT SEP 13 2025
VALID 151200Z - 161200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
ORGANIZED SEVERE THUNDERSTORM POTENTIAL APPEARS GENERALLY LOW ON
MONDAY.
..SYNOPSIS AND DISCUSSION
THE SEVERE THREAT WILL REMAIN LOW ON MONDAY ACROSS THE CONUS. A PAIR
OF WEAKENING UPPER LOWS WILL SHIFT NORTHWARD ACROSS THE NORTHERN
ROCKIES INTO CANADA WITH WESTERLY FLOW ACROSS THE PLAINS AND A
BUILDING HIGH ACROSS THE EASTERN US. A WEAK SURFACE LOW SHOULD
DEVELOP NORTHWARD FROM ND INTO MANITOBA BY MONDAY EVENING, WITH A
WEAK FRONT EXTENDING SOUTHWARD FROM THIS LOW ACROSS PARTS OF THE
NORTHERN/CENTRAL PLAINS. WHILE WIDELY SCATTERED THUNDERSTORM
DEVELOPMENT IS EXPECTED ACROSS THE CENTRAL/NORTHERN PLAINS ACROSS A
MODERATELY UNSTABLE WARM SECTOR, SHEAR WILL BE DISPLACED TO THE
NORTH WITH THE UPPER-LEVEL FLOW WHICH SHOULD LIMIT ANY ORGANIZED
SEVERE THREAT.
ELSEWHERE, A FEW THUNDERSTORMS ARE ALSO EXPECTED TO DEVELOP ACROSS
THE SOUTHERN HIGH PLAINS NEAR THE SURFACE TROUGH. FORCING AND SHEAR
FOR ORGANIZATION WILL ALSO BE NEGLIGIBLE IN THIS REGION. WIDESPREAD
THUNDERSTORMS ARE ALSO EXPECTED NEAR THE UPPER-LOWS ACROSS THE
NORTHERN ROCKIES. WEAKER INSTABILITY AND WEAK SHEAR IN THIS REGION
WILL KEEP SEVERE POTENTIAL LOW.
