A strong low pressure system tracked from Northern Arkansas into Southern Missouri during the evening hours of February 5th, 2008. Supercells developed out ahead of the system during the late afternoon into the early evening. The storms produced tornadoes, large hail and damaging winds. As the supercells moved east during the evening, a cold front moved into West Tennessee. A squall line developed along the front and produced another round of large hail and damaging winds. The front continued to push east into the overnight hours.

A brief EF-2 tornado touchdown occurred in Spring Creek along Highway 152 about one quarter mile west of Highway 70. One home suffered total roof loss and a partial failure of the front exterior wall. Three additional homes received extensive roof damage. Large trees were snapped and uprooted. Maximum winds were estimated at 125 mph with a maximum width of 150 yards.

38 minutes of warning. NWS MEG issued a tornado warning for this county at 00:35 UTC, 38 minutes before the tornado touched down, in force until 01:15 UTC.

The county was under a tornado watch, issued at 21:14 UTC and running to 06:00 UTC.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a High Risk, with a 0.30 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 00:48 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The Memphis radar (KNQA), 117 km away, was scanning. The volume nearest the touchdown began at 01:13 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
