Key Messages
- A prolonged period of wet weather will be seen through late week in the form of three rounds of heavy rain. In between each round, spotty showers and potentially drizzle will be seen.
- Given the long duration of the rain, rises on area rivers will occur. The probability of a flood watch being needed at some point over the next 72 hours is around 30 percent.
- A drier and cooler weather pattern will set up this weekend and into early next week.
