Interesting pressure change today at end of rain shield (Atlanta area)

Pressure dropped 3 MB in 7 minutes… then went back up shortly thereafter. No frontal passage or wind shift… just end back edge of a large rain shield. Nearby NWS station (MGE) caught the same as the tempest. Nice job.

Also… tempest rain came up with 1.68" while COCORAHS gauge had 1.71"… Excellent job Tempest.

BTW here is MGE station pressure graph.
