A boundary will remain nearly stationary to our southwest through this evening. A weak disturbance will track along the boundary later this morning. This will bring scattered to perhaps numerous showers around late morning into this afternoon. The probability for thunder is very low since the boundary will be well to the south of the event location. Primary threats through this afternoon will be locally heavy rainfall. A stronger disturbance will track along the stalled boundary tonight, bringing a better chance for showers and perhaps even a thunderstorm. The best chance for a storm will be after 8 or 9 PM. Once again the main threat for severe weather will remain south of the event location (i.e central and eastern VA). Primary threats for any heavy shower or thunderstorm activity this evening will be locally gusty winds and heavy rainfall. More showers are likely for Friday as another wave of low pressure tracks along the boundary. Friday will be unseasonably cool with temps in the upper 50s and low 60s as well. .REST OF TODAY...
