For the 21/06Z TAF period, VFR conditions prevail this period as
cloud cover is limited only to some thin cirrus streaking across 
the region overnight and expect for mostly SKC conditions through
the remainder of the period. NW winds decoupled with speeds less 
than 5 kts to near calm at a few sites. Light and variable winds 
will prevail at most sites on Wednesday as surface high pressure 
dominates, then going near calm after 22/00Z with some high clouds
moving in from the west.

Historical Weather And Climate Facts For Today

A tornado swarm occurred in the Deep South. Between late afternoon and
early the next morning severe thunderstorms spawned 31 tornadoes in
Alabama, Mississippi, Georgia and Tennessee. The tornadoes killed 334
persons and injured 1784 others. Northern Alabama was hardest hit.
Tornadoes in Alabama killed 286 persons and caused five million dollars
damage. (David Ludlum)
Severe thunderstorms spawned thirty-one tornadoes across Arkansas,
Tennessee, Missouri, Mississippi, Alabama and Kentucky. The tornadoes
killed 343 persons and caused 15 million dollars damage. Arkansas and
Tennessee each reported thirteen tornadoes. The towns of Judsonia AR and
Henderson TN were nearly wiped off the map in what proved to be the worst
tornado outbreak of record for Arkansas. A tornado, one and a half miles
wide at times, left a church the only undamaged building at Judsonia.
