SPC May 13, 2021 0100 UTC Day 1 Convective Outlook

SPC 0100Z Day 1 Outlook Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0735 PM CDT Wed May 12 2021 Valid 130100Z - 131200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...

SUMMARY... Severe thunderstorm threat is low the rest of tonight. ...01z Update... Weak short-wave trough is translating across the northern/central High Plains this evening. This feature appears to be partly responsible for isolated thunderstorm activity that stretches across the western Dakotas into northeast CO. However, with loss of diurnal heating lightning frequency should lessen after sunset. 

Isolated thunderstorms are also gradually decreasing/weakening across the FL Peninsula. Earlier activity has contributed to boundary-layer cooling and weaker buoyancy, along with the majority of convection now observed offshore. 00z sounding from MFL remains unstable but cooling over the next few hours will limit updraft intensity. For these reasons have lowered severe probabilities across the eastern FL Peninsula. ..Darrow.. 05/13/2021 Read more LIVE:
