More rounds of showers and storms will continue tonight and some heat will be here by the weekend.

Tonight: Storms Ending, Mild

Lows: 60s | Wind: Light

Thursday: Partly Cloudy, Warm & Muggy, PM Storms

Highs: Low 80s | Precipitation: 40%

Friday: Partly Cloudy, Isolated Storms

Highs: Mid 80s | Precipitation: 20%

We have another 24 hours or so to deal with an area of low pressure that has been controlling our weather conditions for the past few days. This system, fueled by periods of sunshine that rapidly warm the low levels of the atmosphere, are generating numerous pop-up showers and thunderstorms. This pattern will repeat tomorrow but perhaps to a lesser extent. By Friday, as the system exits the mid-Atlantic, the chance of pop up thunderstorms will drop to only 20 percent. As this is happening, daytime high temperatures will slowly climb into the 80s.

By Saturday, a large area of high pressure will start building into our area. The result will be a preview of summer weather for the holiday weekend. We are forecasting partly cloudy skies with highs around 90 degrees on Saturday. On Sunday and Monday, high temperatures could reach the lower 90s and there will be a 30% chance of isolated afternoon thunderstorms. The chance of storms will increase on Tuesday as the next frontal zone approaches.
