Severe Weather on February 5, 2008 (Pg1) |
 |
| |
| A
Tragic Event/A Record Event |
| |
| Tornadoes claimed the lives of at least 13 Arkansans on
the 5th. Two parent storms spawned two tornadoes in a
nine county area in northern and central sections of the state. The tornadoes
caused extensive damage. This was the deadliest severe weather event in the
state since March 1, 1997 when 25 people were killed. It was also an
historic event. One of the tornadoes tracked 123 miles, which is the
longest track on record in Arkansas since 1950. |

that entered from or exited into neighboring states. |
| There were eight additional tornadoes counted elsewhere in
the state (a total of ten tornadoes). These tornadoes were generally
weak. |

| What
Happened |
| |
| Early on the 5th, a strong storm system approached from the Plains. Ahead of the system, breezy southerly winds
provided well above normal temperatures (record high readings in some areas) and abundant moisture from the
Gulf of Mexico. Warmth and moisture destabilized the atmosphere and fueled developing thunderstorms. |
 |
Storms began popping up from northeast Oklahoma into
southwest Missouri and extreme northwest Arkansas during the morning of the 5th. Winds aloft
picked up markedly...which created a lot of lift. Unstable air was drawn
quickly upward...leading to the precipitation. |
| In the picture:
The pattern at 6 am CST on 02/05/2008...with an interaction between the
Polar and Subtropical Jets (wind speeds are in knots) creating a lot of
lift in northern and western Arkansas. Thunderstorms become likely, with areas
of heavy rain. |
| By afternoon, the system in the Plains dragged a cold
front into the state. Thunderstorms became more numerous, with severe
weather likely (especially between 2 pm and 10 pm CST). Winds turned with height, and caused some storms to
rotate. Two killer tornadoes were spawned, with one of them on
the ground for 123 miles! |
|
| In the picture:
Helicity (representing the potential for rotating winds) was high
(over 200 m2/s2) and CAPE (Convective Available Potential Energy...or a
measure of instability) was ample enough (over 1000 J/kg) for severe
weather during the afternoon and evening of 02/05/2008. |

This long track tornado caused extensive damage
from Atkins (Pope County) to Clinton (Van Buren County),
Mountain View (Stone County) and Highland (Sharp County). |
| In the picture:
WSR-88D (Doppler Weather Radar) Storm Relative Velocity Map (SRM) images indicated strong rotation from east
of Russellville (Pope County), or around Atkins (Pope County), to Clinton (Van Buren County) between 502
pm and 536 pm CST on 02/05/2008. |
| At least four people were killed near Atkins (Pope County), and there were
three deaths in Van Buren County. |
|
| In the picture:
Two deadly tornadic supercells (storms with rotating updrafts) moved
across northern Arkansas on 02/05/2008. Storm #1 produced one long track
tornado (123 miles). There was one tornado with Storm #2 as well. At least 13
people were killed (4 deaths in Pope County, 3 deaths in Van Buren
County, 2 deaths in Conway and Izard Counties and 1 death in Baxter and
Stone Counties). |
| The other tornado was spawned farther north from near Rea Valley
(Marion County) to Gassville (Baxter County). One death was reported in
the Gassvile (Baxter County) area. In all, at least 13 fatalities
have been reported. |
