/ISSUED 904 PM CST THU FEB 11 2016/
REGIONAL RADAR THIS EVENING HAS SOME VERY LIGHT RETURNS STREAMING IN
FROM THE NORTHWEST OUT OF WESTERN TN. 03Z SURFACE OBS INDICATE THAT
THE CLOUD BASES ASSOCIATED WITH THESE RETURNS ARE AROUND 10KFT AND
WITH A CONSIDERABLE DRY LAYER BENEATH THESE CLOUDS MOST OF THE
RETURNS ARE ASSOCIATED WITH VIRGA. SATELLITE IMAGERY DOES HAVE A
FAIRLY WIDE SWATH OF HIGH LEVEL CLOUDS STREAMING IN FROM THE NORTHERN
PLAINS AND WENT AHEAD AND ADJUSTED SKY GRIDS TO ACCOUNT FOR THE
INCOMING CLOUDS.

A SLIGHT INCREASE IN WINDS THE LAST HOUR OR TWO HAS HELPED TO KEEP
THINGS MIXED AND HAS SLOWED THE DIURNAL TREND. THIS IS MOST LIKELY
RELATED TO AN INVERTED TROUGH THAT IS EVIDENT IN THE LATEST HOURLY
RAP SURFACE ANALYSIS OVER WESTERN TN. THIS MAY KEEPS TEMPS AT THE
CURRENT VALUES FOR ANOTHER HOUR OR TWO BUT BELIEVE THAT WINDS WILL
TAPER OFF AFTER MIDNIGHT THAT THE CLOUD COVER WON`T HAVE MUCH OF AN
INFLUENCE ON TEMPS TONIGHT. EXPECT TEMPS TO BOTTOM OUT IN THE MID TO
UPPER 20S FOR THE NORTHERN HALF AND AROUND THE FREEZING MARK FOR THE
SOUTHERN HALF OF THE AREA. THE REST OF THE FORECAST IS IN GOOD SHAPE.

.AVIATION...
FOR 06Z TAFS...
A QUICK MOVING UPPER LEVEL SYSTEM WILL DROP SOUTHEAST OUT OF THE
NORTHERN PLAINS STATES AND INTO THE MIDSOUTH TONIGHT. MID AND HIGH
LEVEL CLOUDS OUT AHEAD OF THIS FEATURE HAVE MOVED INTO THE AREA BUT
NOT EXPECTING CIGS TO LOWER MUCH BELOW THE 10KFT LEVEL. WINDS WILL
FAVOR A E/NE DIRECTION AHEAD OF THE WAVE THEN SWITCH TO NW AS THE
SYSTEM MOVES THROUGH. VFR CONDITIONS ARE EXPECTED THROUGH THE ENTIRE
TAF PERIOD.
