Sure is. It seems to me like anytime you start getting numbers out quickly after a tornado strike, there are usually more to come.
Looks like a significant hit from a long track tornado. What was the final tally on mileage for that one?

West County Mall in western St. Louis took some damage due to possible tornado.

This may be what FoxNews.com is reporting...or unfortunately it may be numbers that aren't yet added to the tally. 
"In Choctaw County in central Mississippi, WTVA News reported at least seven people died after a severe storm ripped through the French Camp area. The sheriff's office would only confirm there were multiple fatalities and injuries, along with widespread damage."

I'd say it is unlikely it was a single tornado, but you never know.

AREAS AFFECTED...SERN MS/SRN AL/FL PANHANDLE
CONCERNING...TORNADO WATCH 95...
VALID 250019Z - 250115Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 95 CONTINUES.
A NEW TORNADO WATCH MAY BE NEEDED ACROSS SRN AL AND THE FL PANHANDLE
THIS EVENING.
RECENT SURFACE ANALYSES SHOWED A DRY LINE/WIND SHIFT PROGRESSING EWD
THROUGH WRN TN...NERN TO SOUTH CENTRAL MS AND SOUTH CENTRAL LA.
AT 2345Z...REGIONAL RADARS SHOWED NEW TSTM DEVELOPMENT ALONG THE DRY
LINE IN FAR NWRN AL...AND EAST CENTRAL TO SRN MS. THESE NEWLY
FORMED STORMS ARE DEVELOPING WITHIN A MODERATELY UNSTABLE
ENVIRONMENT AND THE ENTRANCE REGION OF THE UPPER JET ACROSS THE TN
VALLEY. MEANWHILE...WATER VAPOR IMAGERY INDICATED AN UPSTREAM SPEED
MAX/IMPULSE CURRENTLY TRACKING EWD ACROSS E TX. LOW LEVEL WINDS PER
LOWER MS VALLEY VWP DATA ARE BACKING...LIKELY IN RESPONSE TO THE
APPROACH OF THE E TX IMPULSE AND SUBSEQUENTLY INCREASING LOW LEVEL
CONVERGENCE ACROSS ERN-SRN MS WHERE THE NEW STORMS HAVE DEVELOPED.
EFFECTIVE SRH 300-600 M2/S2 AND 0-1 KM SHEAR 30-40 KT REMAIN
SUPPORTIVE OF ROTATING UPDRAFTS AND TORNADO THREAT. STEEP LAPSE
RATES/MIDLEVEL COOLING SPREADING EWD ATOP THE EXISTING RICH LOW
LEVEL MOISTURE WILL ALLOW FOR DESTABILIZATION FROM W-E THIS EVENING
WITH MODERATE INSTABILITY EXPECTED INTO SRN AL/WRN FL PANHANDLE.
THIS MIDLEVEL COOLING WAS EVIDENT IN THE COMPARISON OF THE 18Z TO
00Z JAN SOUNDINGS. 00Z TLH SOUNDING INDICATED THE BOUNDARY LAYER
HAS DEEPENED SOME...WHILE COOLING IN THE 850-700 MB LAYER HAS
REDUCED SBCINH SUFFICIENTLY TO SUPPORT SURFACE BASED STORMS.
ALTHOUGH FAR SRN AL AND THE FL PANHANDLE WILL BE GENERALLY GLANCED
BY MIDLEVEL COOLING AND ASCENT...THE DEGREE OF INSTABILITY AND SHEAR
VALUES SUGGESTS THE SEVERE WEATHER THREAT MAY NOT DIMINISH THIS
