NWS STORM PREDICTION CENTER NORMAN OK
1112 AM CDT WED SEP 16 2026
VALID 161630Z - 171200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
NORTHERN UTAH...AND PARTS OF OHIO AND VICINITY....
..SUMMARY
ISOLATED STRONG TO SEVERE THUNDERSTORMS APPEAR POSSIBLE TODAY ACROSS
PARTS OF THE MIDWEST/OHIO VALLEY AND UTAH/FAR NORTHWEST COLORADO.
..OH AND VICINITY
MORNING VISIBLE SATELLITE IMAGERY SHOWS BROKEN CLOUD COVER ACROSS
MUCH OF OH, WHICH WILL ALLOW POCKETS OF HEATING/DESTABILIZATION AND
LEAD TO MODERATE CAPE VALUES BY MID-AFTERNOON. WIDELY SCATTERED
THUNDERSTORM DEVELOPMENT IS EXPECTED, IN A REGIME OF RELATIVELY WEAK
WESTERLY FLOW ALOFT AND POOR LAPSE RATES. PWAT VALUES APPROACHING 2
INCHES AND RATHER STEEP LOW-LEVEL LAPSE RATES COULD RESULT IN
PRECIP-LOADED DOWNDRAFTS CAPABLE OF STRONG OR OCCASIONALLY DAMAGING
WINDS.
..UT
MOISTURE HAS INCREASED ACROSS UT OVER THE PAST 24 HOURS, WITH
DEWPOINTS NOW IN THE LOW-MID 50S AND PWAT VALUES OVER 1 INCH. THIS
ALONG WITH AMPLE HEATING WILL LEAD TO SCATTERED AFTERNOON
THUNDERSTORMS. A BAND OF 35-45 KNOT SOUTHWESTERLY MID-LEVEL WINDS
ACROSS THIS AREA WILL PROVIDE SUFFICIENT DEEP-LAYER SHEAR FOR A FEW
ROTATING STORMS CAPABLE OF HAIL AND GUSTY WINDS.
