Two waves of storms on Sunday bring heavy rainfall, gusty winds, and a threat of severe weather. The first wave comes in the form of scattered thunderstorms: a few of those may produce hail or strong winds through early evening. A second wave forms along a strong cold front this evening and moves out of North Alabama by midnight.
Specific timing and location on the most severe storms comes on a storm-by-storm basis; in other words, be alert and listening for warnings so you can take appropriate measures to protect yourself if one of the storms approaches you. Most of us just get rain and some wind; a few could experience wind greater than 60 MPH, hail, or a tornado. While we do not expect a historic ‘outbreak’ of tornadoes, we do expect rotating storms capable of producing tornadoes. Be on guard through the evening.
Expectations through midnight:
- Worst-case scenario: severe storms that produce a few tornadoes and wind gusts over 60 miles per hour knocking down trees and disrupting electricity.
- What most of us will see: a lot of rain (up to 1.5″) and occasional wind gusts over 25 miles per hour.
- When does it end? Storms will be gone by midnight (from North Alabama and Southern Middle Tennessee).
