I'm not sure if you guys noticed, but there has been a constant shower just north of the mouth of the Potomac river in St. Mary's County for hours and hours. If you start a radar loop from yesterday morning, there's a shower that just kept refiring for hours and hours. It died out last night but briefly refired this morning. I don't know how to pull radar loops from a previous day, but I just noticed that the area just keeps getting inundated with stationary rain showers.
That has got to be tied to geography right?
