During the afternoon of January 3rd, a strong upper level low was moving through the central Plains and a cold front began to move into the region. Across the Lower Mississippi River Valley, peak heating and upper 60s to low 70s dewpoints contributed to decent instability in the developing warm sector in advance of the front. Strong low level wind shear and winds aloft were in place, which made a favorable environment for tornadoes. This helped to support widespread thunderstorms along with a few supercell storms.
In addition to the severe storms and tornadoes, widespread flooding occurred in southeast Mississippi where 3-5 inches of rain fell. Record amounts of moisture for the month of January were observed in the evening weather balloon sounding at the Jackson International Airport, where precipitable water value of 1.74 inches tied the record last set on January 3, 1973. This led to widespread heavy rainfall and flooding. Water coRose Hill Damage covered some roads and water was entering homes near Bay Springs, with one road washed out nearby.
