Well, the good news is that it will be a bit cooler today than yesterday, but there is still the chance for storms later today. The cold front remains over PA and will drop towards MD than stop. The stationary nature of the boundary is one of the factors keeping us in a stormy pattern. Until that front moves down through MD the temps will remain hot and storms possible through Saturday. Other factors influencing storm development today are the humidity, dew points, a low pressure system to our west, and the remnants of storms from OH moving this way. Most of today there will be a layer of clouds, so maybe the temps and instability will be a bit lower, but not much.
TIMING: Primarily after 3:00pm into the evening. Most of the storms should occur in the same places as yesterday, but everyone in central and southern MD have the potential for storms.
THREATS: Strong winds and flash floods. Some potential for hail, but wind and rain amount is a greater threat today.
Thus far there are no watches/warnings, although I expect at least a thunderstorm watch to be issued later. In some areas you could also have flood or flash flood products issued.
