US Hazards

Severe Thunderstorms with a Significant Risk for Tornadoes for Portions of AL, GA, and TN
A potent spring-time low-pressure center will interact with a favorable environment to produce a significant round of severe thunderstorm activity from central Tennessee southeastward across much of Alabama and Georgia today. The peak of the severe weather threat is likely to occur from 3 PM to 9 PM eastern time. The highest threat for tornadoes and large hail is focused across south-central Tennessee and the northern half of Alabama. Environmental conditions do appear to support the possibility for at least one or two intense/long-track tornadoes in this area.

Region 1

Increasing Nor'easter Threat from the Mid-Atlantic into New England for Mid-week
The low pressure center bringing severe weather to the Tennessee Valley and Deep South today will continue it's eastward journey through midweek, likely developing into a nor'easter by Wednesday. This will result in a variety of winter weather threats from the Mid-Atlantic northeastward into southern New England. There remains uncertainty regarding just how widespread the heavy snowfall will be but interests from the upper Ohio Valley and Mid-Atlantic states northeastward to coastal Maine should continue to closely monitor weather forecasts this week.
