Through Monday morning
Rain will develop from a stalling front this evening, then continue through Sunday morning. Then, a strong low pressure system will move through the region Sunday afternoon through Monday morning, with additional rainfall, which will be heavy at times. Widespread rainfall totals of 2 to 4 inches are expected, but locally higher amounts are possible. There remains some uncertainty for where the heaviest amounts will occur.
Though rain will begin tonight to early Sunday, the primary period of concern will be Sunday afternoon through Sunday night, as additional heavy rainfall occurs on top of soils that will be very wet from the earlier rains. Flash flooding will be possible, where the heaviest rain bands occur. Also, as area rivers respond to the widespread rain, some river flooding could occur into Monday.
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.
You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
