Every forecast across The Delta,
highway-clear.

Every Tennessee region shares one system — the same maps, the same live radar, the same climate record. Memphis stands on the Chickasaw Bluffs at the top of the Delta, the only high ground the lower Mississippi offers for a hundred miles — which is why the city is there and why the flat country around it floods. It is the warmest corner of Tennessee and the one with the least terrain to slow a squall line down, and the 1811–12 New Madrid quakes that made Reelfoot Lake happened just upriver.
