significant rainfall for the latter half of the week

As of early Wednesday afternoon, Tropical Storm Debby is barely moving while situated off the South Carolina coast. Rain is continuing for coastal Georgia and South Carolina, with many locations there having already received 8-12 inches of rain.
The upper level pattern will allow Debby to resume a more northward motion by Thursday. Over the past couple days, computer models have shifted westward with its track through the Mid Atlantic heading into Friday. This would put the heaviest rain west of our area.
For this Wednesday, a frontal boundary is already in place near the area, which is helping to generate showers and thunderstorms this afternoon. Some thunderstorms may continue into the evening.
Thursday, additional showers and thunderstorms can be expected as moisture continues to stream northward. The remnant circulation of Debby will be tracking northward through Virginia on Friday. Expect a continuation of showers and thunderstorms. There may also be a threat for an isolated tornado due to the atmospheric dynamics in place from the storm’s circulation.
Saturday is now looking drier. Through Saturday morning, I am thinking Southern MD will have 1-3” of rain. Rainfall amounts may still be higher in any spots where thunderstorms may end up being more concentrated.
