May 29: Bonnie Weakens. Wet Memorial Day
Bonnie reached tropical storm criteria yesterday but has since weakened into a tropical depression. It will stall in the coastal South Carolina area for a few days before eventually being lifted out to the NE early next weekend by a frontal boundary passage. Our more-immediate concern is an area of precipitation that will break off of the weakening storm and slide up a frontal boundary passage tonight through early Tuesday morning.
This makes Monday a rainy day with anything from .75 to 1.75 inches of rainfall possible. This rainfall might have a drenching tropical feel to it so it could be heavy at times. With that said, flash flooding is also possible. Another thing to consider is any thunderstorm activity that forms along the frontal boundary itself. Such activity would likely be embedded within the widespread rainfall and we’ll have to pay attention to any winds that get kicked up.
In English: Memorial Day Weekend had a good run with a few summery days leading up to and through today. Tomorrow however will not be a good outdoor day as moderate-to-heavy rainfall and possibly embedded thunderstorms are possible. The good news is that pleasant weather is expected this week once everything clears by early Tuesday morning. I’ll post a Tuesday-Friday outlook tomorrow evening. Have a great rest of your Memorial Day Weekend and please be safe! JC
