Not only are we looking at a significant rain event, but also may a possible winter weather event this coming weekend. As usual, the forecast could change concerning winter weather but confidence is very high for a significant amount of rain.
First a 7-day projection on rainfall. Note the location of the 6.6" x on the map.
This is an excellent time to review Flood Safety and please make a plan if you live or work in an area which is prone to possible flooding.
In summary, expect a major weather event with rain starting on Thursday including possible thunderstorms. The rain will continue into Thursday night, Friday, and Friday night with a possible changeover to all winter precipitation on Friday night. A cold rain is possible on Saturday.
