jgf Posted January 23, 2017 Share Posted January 23, 2017 So, when NWS says A strong southern branch upper low over the Tennessee Valley this morning will send a deepening surface low off the Mid Atlantic coast this afternoon. does "southern branch" just refer to the geographic location? as far as i know there is no officially designated "southern branch" of the NWS... it's in today's AFD from Upton NY, discussing the big storm expected later today Link to comment Share on other sites More sharing options...
