Saturday Storm System

Another upper-level disturbance looks like it will track through our region Saturday, developing a low-pressure system just off the coast of the Carolinas. This low will hug the coastline as it moves northeast Saturday and Sunday, and bring moisture into the area that will start out as rain on Saturday morning. As colder air is pulled into Central Virginia, rain may change over to a wet snow or wintry mix Saturday late afternoon. If this does occur, accumulation would be limited by surface temperatures remaining above freezing while the precipitation is falling. In any case, it does look like Saturday will have a cold rain in Central Virginia with temperatures remaining above freezing at the surface. Precipitation is expected to end overnight before temperatures at the surface fall below freezing Sunday morning. Any thin, wet spots on pavement, though, may freeze Sunday morning, such as on your front steps or sidewalks.

Severe Threat Expired For All Of VA


The low pressure storm system responsible for Wednesday's rainfall is rapidly exiting northward early Thursday, ending the tornado and severe weather threat in the Commonwealth. The Tornado Watch for the Middle Peninsula and the Eastern Shore is also now expired. In fact, the watches have expired throughout the Southeast U.S., except for in Central Florida. In addition, the Flood Watch in north-central Virginia has also expired.
These are the official severe weather reports from Wednesday from this storm system:

Tornado Watch Cancelled For Central VA

The Tornado Watch has been lifted for most of central Virginia. However, it still remains in effect until 4 AM for far eastern Virginia (Middle Peninsula, Eastern Shore, Norfolk area).
