Gradient winds will once again be brisk, but should remain just 
below advisory criteria. Will need to monitor through the morning 
for any changes here. High pressure will begin to build into the 
area late afternoon into the evening and winds will begin to relax 
quite a bit. Overnight the high will slide into western Tennessee 
and we will see almost calm winds area wide. Dewpoints will remain 
high in regards to the temperatures so a frost will be possible 
across the area. Areas across the north will drop to or just below 
freezing, so a Freeze Warning has been issued. A Frost Advisory has 
been issued for the rest of the counties, with reading of just above 
32 to 36 degrees. 


Thursday through Wednesday.

A highly amplified pattern sets up through the end of the week with 
troughing along the East Coast and Ridging sliding through the 
center CONUS. Surface high pressure will build in across the Gulf 
States Thursday and Friday leading to drier weather and mild temps 
for Central AL. Later Friday evening/night, a surface low slides 
through the Central Plains and into the Ohio River Valley, 
stretching a cold front through the MS and TN River Valleys. This 
cold front will push north to south through Central AL Saturday and 
Sunday bringing a chance for rain. Moisture return ahead of the 
front looks limited, and instability is minimal, so have taken out 
mention for thunderstorms and carried Chance PoPs in the forecast 
for the weekend.

The highly amplified pattern continues for early next week as a 
strong low upper level trough dips into the Great Basin on Monday 
while ridging builds in, once again, over the Gulf States. High 
pressure sets up around the middle of next week with the trough 
still off to the west. This could lead to isentropic lift and 
increased rain chances for the MS River Valley. This could spread 
into the TN Valley and into northern portions of Central AL by 
midweek, but confidence isn't high this far in advance, so have gone 
with 50% chance of rain for now. 

Otherwise, mild temperatures expected for the remainder of this 
week, through the weekend, and into early next week.

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.
