Wet This Morning


Rain will continue for the next few hours and will be heavy at times. Showers will become more widely scattered later this afternoon and evening. There is still a chance for isolated thunderstorms between 4 and 9 PM for the southeastern corner of the state. I will track this scenario later in the afternoon and have another update.

Thunderstorms Tomorrow?

Rain will overspread the area tonight and persist through the first half of tomorrow. Hit-and-miss showers will then linger into the afternoon and evening. During this time period one or two thunderstorms could develop in the far southeast corner of the state. The surface low will drag in some relatively humid air...dew points could reach the upper 50s near Norfolk.


The upper low will then swing by in the late afternoon and evening.


Instability will be limited, but there should be enough lift for an isolated thunderstorm near Norfolk and areas farther south.

Sunday Storm System

A low pressure system is organizing over Texas today, and will strengthen along the Gulf Coast into this weekend as it tracks eastward. This storm will turn northeast Saturday and cross through Georgia, the Carolinas, and onto Virginia by early Sunday morning, bringing rain to the region. The latest data still indicates that the precipitation mode will be rain in Central Virginia, as temperatures will remain above freezing both at the ground and in a deep enough layer above the surface. Rain is expected to overspread the Commonwealth from the Carolinas by early Sunday morning, and rain will be likely through the entire day while the low tracks through the area. Here is a snapshot of the low's expected position on Sunday morning:
