Key Messages
- A moisture surge will support bouts of elevated rain and thunder chances for the remainder of the Labor Day holiday weekend.
- The primary threat for any stronger thunderstorms will be dangerous lightning strikes. When thunder roars, go indoors. If on a boat, stay low, or go below.
- Heat indices will approach the mid 100s daily, with little relief in the muggy conditions overnight. Know the signs of heat stress, take frequent breaks, and stay hydrated.
