I received this email from FOB (Friend of the Blog) Chuck Biddinger after I commented that the rain area had split over Birmingham Friday morning:
This morning when there was a solid line in north AL, I started to post on the blog that it would break up as it got to my house in Roebuck.
I should have posted it!
Chuck
Chuck always says that it can be raining everywhere in the area, but miss his house in Roebuck.
It did appear that the Greater Birmingham Anti-Rain Force Field (GBARFF) was on full power. Look at the estimated rainfall from the BMX Doppler from Friday.

Notice the huge rain free area through much of Central Jefferson County into Shelby, southern Talladega and Coosa Counties. No rain fell in these areas.
