EVENT SUMMARY:

 

On January 22nd, an unusually strong weather system was making its way towards the Midsouth. A low pressure system developed over the southern plains and moved to the northeast. The strong low pressure system had moved to the Kansas and Missouri border by the time the event started. A very strong low-level jet, along with a very strong jet stream, moved across the Midsouth during the evening hours. An upper level short wave moved across Arkansas during the early evening hours. This short wave was the focus of thunderstorm development. The storms initially began as supercells, producing numerous large hail and tornadoes across the portions of Arkansas served by WFO Little Rock. A couple of those tornadoes were strong. By the time the storms started crossing into the WFO Memphis area, the storms had begun congealing into a squall line. A few supercells did develop ahead of the squall line, but thankfully no tornadoes were spawned by these storms. The potential for strong tornadoes was high across the Midsouth; however, there was not enough instability to keep the updrafts sustained and the storms more discrete. Cloud cover through the peak heating time (mid to late afternoon) prevented higher temperatures across the region; thus, reducing the amount of surface based CAPE (Convective Available Potential Energy). Also, the storms moved through during the nighttime hours, which likely added to the reduced CAPE values. As a result, only 3 weak tornadoes occurred in the WFO Memphis area of responsibility.  These tornadoes formed in small scale areas of rotation embedded in the squall line. However, there were plenty of wind damage reports due to the squall line. The squall line was able to produce very strong winds in the bowing segments because the thunderstorms were able to force the strong low level jet down to the ground. Additional storms developed later that night ahead of the squall line across WFO Birmingham's area that produced some strong tornadoes.
