He's here! As I previously mentioned, the remnants of Isaac are effecting us this weekend. I know it is a holiday weekend, but even tropical systems want to travel on the holiday. The current satellite imagery shows that the cloud cover over us today are the outflow from what was Isaac. Isaac's influence will increase through Monday. Another "complication" is a cold front dropping down from PA which will later stall in central VA. The stalled front will cause unsettled weather and a flow from the east. So, the easterly flow draws moisture from the Atlantic into the area, coupled with the moisture from Isaac moving in from the west. Yup, that equates to a good amount of moisture. We could see upwards of 2+ inches of rain by Monday evening.
TIMING: It is not easy to nail down the timing as the moisture is already here and continues to build. Rain will form as the moisture builds and saturates the atmosphere (column of air). But, we could see more prolonged rain Sunday afternoon and again Monday afternoon. Scattered rain is possible all other times.
THREATS: Heavy rainfall and local flooding is possible. Gusting winds are also possible.
TROPICS: No threats to MD on the horizon.
