Periodic rain likely through Thursday, flood risk low

RICHMOND, Va. (WWBT) - Keep your rain gear handy the next several days, because periods of rain are likely through Thursday across Central Virginia.

A slow moving area of low pressure will be located just to the south of Virginia and will barely move this week. This slow moving low pressure is called a “cut-off low” because it is cut-off from the jet stream that steers our storms. Without the jet stream to steer the low pressure out of the area, it just sits and spins delivering repeated chances for rain along with cooler than average temperatures.

A slow moving area of low pressure will drift near Virginia for the next few days, locking in clouds and rain showers through Thursday.

The NBC12 First Alert Weather team will closely watch the potential for a couple of strong to severe thunderstorms on Wednesday, especially south of Petersburg. The Storm Prediction Center has highlighted a low, marginal risk (1 out of 5) for severe weather on Wednesday. We cannot rule out a brief spin up tornado and gusty winds with any thunderstorms that develop on Wednesday from the midday into the afternoon (roughly 11 a.m. to 6 p.m.).

There is a low end threat for a couple of strong to severe storms on Wednesday, mainly south of Petersburg.

Despite the prolonged period of rain chances, our flood risk is expected to remain low. The ground has been relatively dry lately, and some areas of Central Virginia do need the rain to help out gardens, lawns, and farms. The on and off nature of this upcoming rainfall will also allow time for the rain to runoff without causing much flooding.

There could be an additional 2 to 3 inches of rain across much of Central Virginia between now and Thursday night.

1 to 3 inches of rain is likely between now and Thursday night across Central and Southern Virginia.

Abundant clouds and showers will keep temperatures stuck in the 70s through at least Wednesday. Once the area of low pressure moves out and sun returns, it heats up big time for the upcoming weekend. High temperatures likely reach the 90s on Saturday and Sunday.

Dew points will also climb with increasing humidity late this week into the weekend.

Humidity will climb the next few days and it will be muggy in Virginia from Thursday into Friday.
