Severe Storms

SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0218 PM CDT Sat Mar 15 2025 Valid 171200Z - 181200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe thunderstorms are not expected on Monday. ...Discussion... A quiescent pattern for severe potential should return to the CONUS on Monday. Low-probability thunder may linger during the first couple hours of the period Monday morning across the NC Outer Banks and a sliver of southeast FL before entirely shifting off the coast. In the West, a broad upper trough will move onshore and should amplify amid multiple embedded shortwave impulses. Cool mid-level temperatures should aid in scant to meager buoyancy, with low-topped convection peaking in scattered coverage during the afternoon to early evening. Some of this activity should produce sporadic lightning, most probable in parts of the Central Valley of CA. Otherwise, thunderstorm coverage appears very isolated from the northern CA/southern OR coast into the Great Basin. ..Grams.. 03/15/2025 Read more
