NWS STORM PREDICTION CENTER NORMAN OK
0518 PM CDT SAT JUL 19 2025
AREAS AFFECTED...PARTS OF EASTERN NEBRASKA INTO FAR WESTERN IOWA
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 192218Z - 200015Z
PROBABILITY OF WATCH ISSUANCE...40 PERCENT
SUMMARY...SHOULD STORMS DEVELOP, LARGE HAIL AND SEVERE WINDS WOULD
BE POSSIBLE. CONVECTIVE TRENDS WILL CONTINUE TO BE MONITORED, BUT A
WATCH IS NOT ANTICIPATED IN THE SHORT TERM.
DISCUSSION...STORMS THAT DEVELOPED AND SHOWED BRIEF INTENSITY IN
NORTHEAST NEBRASKA HAVE SINCE WEAKENED. ADDITIONAL CUMULUS
DEVELOPMENT HAS BEEN NOTED ALONG ANOTHER SURFACE BOUNDARY IN
EAST-CENTRAL NEBRASKA. WHILE STRONG HEATING AND A VERY MOIST AIRMASS
HAS ALLOWED MLCAPE TO RISE ABOVE 3000 J/KG, FORCING FOR ASCENT
REMAINS NEBULOUS. WITH THE WEAK FORCING AND ANVIL CIRRUS FROM A
CLUSTER OF SUPERCELLS IN WEST-CENTRAL NEBRASKA MOVING IN, WHETHER
ADDITIONAL STORMS CAN INITIATE THIS AFTERNOON IS NOT CLEAR. STRONG
EFFECTIVE SHEAR AND THE LARGE BUOYANCY WOULD SUPPORT AT LEAST BRIEF
STORM ORGANIZATION AND POTENTIAL FOR LARGE HAIL AND SEVERE WIND
GUSTS. WATCH ISSUANCE IN THE SHORT TERM IS NOT CERTAIN, BUT
CONVECTIVE TRENDS WILL CONTINUE TO BE MONITORED.
