Coastal Threats for the East and Gulf; Record Warmth for the Central U.S.

Persistent onshore flow across the Southeast and portions of the mid-Atlantic will keep the risk of rip currents through the weekend. Rainfall could be locally heavy across Florida, especially along the eastern shoreline. Meanwhile, record warmth for portions of the Plains and Midwest with elevated fire concerns.

Significant Tornado (SigTor)

A composite index that includes 0-6 km bulk wind shear, 0-1 km storm-relative helicity, surface based CAPE, surface parcel CIN, and surface parcel LCL height. Values greater than 1 are indicative of increased potential of significant tornadoes.

The contours are the Lifted Condensation Level or LCL. A lower LCL typically increases tornadic risk because it is indicative of air parcel acceleration occurring closer to the surface.
