.SHORT TERM(Today thru Fri Night)...

Will continue with Winter Wx Advisory thru 21/15Z(10 AM CDT) per
supporting sfc obs, especially showing light snowfall continuing
across the Cumberland Plateau Region, along with regional radar
mosiac imagery. As a result, will also continue with Special Wx 
Statement thru 21/12Z(7 AM CDT), but may update it an extend it to
15Z(10 AM CDT) dependent on current sfc obs and regional 
satellite imagery/radar mosiacs as 7 AM CDT approaches.
Will be continuing the freeze warning for entire mid state thru 
21/15Z(10 AM CDT). With pronounced clring tonight, light winds, 
and Canadian based sfc high pressure influences becoming more 
established across region, issued another freeze warning for 
entire midstate from 22/06Z (1 AM CDT Thu) to 22/14Z (9 AM CDT 
Thu). Also mentioned widespread frost across the mid state region 
during this time period too. Will break out an early this morning 
grouping in the zone forecast product to properly highlight wx 
conditions thru 12Z(7 AM CDT). Will then update shortly after to 
mesh with current obs conditions and the latest in consensus short
term model reasoning.

Otherwise, expect exclusively light snowfall production to end 
after 10 AM CDT, except for highest elevations of Upper 
Cumberland Region approaching the KY border. As upper level system
slowly turns eastward, a change over to a light rain/snow mix 
across locations just west of and across the remainder of the 
Cumberland Plateau Region is expected as the morning hrs progress.
A wintry mix will even persist into the afternoon hrs for the 
higher eastern elevations of the Upper Cumberland Region. With 
above mentioned Canadian based sfc high pressure influences 
becoming more entrenched across the mid state region as the day 
progresses, afternoon high temps for today will in some locations
be around 15 degrees below seasonal normal values. Afternoon 
highs today will be generally in the 45 to 50 degrees, upper 30s 
to lower 40s for locations just west of and across the Cumberland 
Plateau Region. Look for any pcpn chances to end by the start of 
this evening, with overnight lows generally in the lower 30s for 
locations west of and around I-65, with lows 25 to 30 degrees for 
locations east of I-65, with clring skies and light winds

A warm up will commence on Thu and into Fri across the mid state
region. Afternoon high temps by Fri will at least be in range of
seasonal normal values for locations west of I-24 where warm air
advection will become most pronounced. Northwesterly upper level
flow will by Thu afternoon usher in some additional cloudiness to
the mid state region. Possible weak upper level disturbances in 
nwly flow aloft across the mid state region will be possible Thu
night into Fri night as upper level ridging influences begin to 
build across the mid state region as an upper level trough begins
to develop across cntrl and srn portions of the MS River Valley
Region. A sfc frontal system will move out of the lee of the
Rockies into the mid MS River Valley also by sunrise on Sat
morning. Do not have a lot of confidence in model solutions at
this point when it comes to depicting areal coverage of any short
wave induced rainfall across the mid state region Thu night
into Fri night. Maybe some isolated light shwrs across western 
portions of the mid state region Thu night into Fri, with a more 
pronounced chance across the entire mid state Fri night as swly 
sfc flow becomes more established ushering in a more unstable air 
mass to our region. This warm air advection scenario and increased
cloud coverage on Fri night will keep overnight lows Fri night 
spanning from the lower 40s Cumberland Plateau Region to upper 40s
TN River Valley Region.


.LONG TERM(Sat thru Tue)...

The extended period will be unsettled, with several systems bringing 
chances for showers. The first will bring a good chance for 
showers Saturday, tapering off Saturday night. In Mid TN. this 
system is expected to produce from one quarter inch of rain 
southwest to as much as 1 inch northeast. Temps on Saturday will be 
mild with highs in the 60s. Lows will drop to the 40s. Sunday 
will bring the lowest rain chance in the extended period with 
the area in between rain-producing systems. Highs will be mainly 
in the lower 60s. 

Chances for showers return by Sunday night, and will continue on and 
off through midweek as southwest flow aloft brings moisture 
and several disturbances across the region. Highs will be mainly in 
the 60s with low mainly upper 40s to lower 50s. A few thunderstorms 
will be possible next week, but we do not expect severe wx.

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.
