Flash Flood — Mar 15, 2025
An upper low over the Central Plains moved into the Upper Mississippi Valley during the evening hours of Friday, March 14, 2025. Increasing moisture advection ahead of an approaching cold front lifted dewpoints into the low to mid 60s. This coupled with increasing height falls and a mid-level 80 knot jet rotating around the main upper low supported severe thunderstorm development. Large looping...
Flash Flood — Mar 31, 2021
A cold front pushed into a moist and unstable airmass resulting in numerous showers and thunderstorms across West Tennesee and North Mississippi during the early morning hours of March 31st. Heavy rainfall resulted in flash flooding while a few severe storms produced damaging winds and a couple of weak tornado across Northeast Mississippi.
Flash Flood — Jun 9, 2021
An upper low continued to meander across the region on June 9, 2021. Weak upper-level disturbances rotated around the upper low and interacted with a very moist air mass across the Mid-South to produce several rounds of heavy rain across East-Central Arkansas and North Mississippi. There were several instances of flash flooding.
Flash Flood — Jan 11, 2020
A cold season quasi-linear convective system (QLCS) moved across the Mid-South during the overnight and early morning hours Saturday, January 11, 2020. Strong southerly winds drew unseasonably warm, moist air northward into the region ahead of a cold front. Early morning temperatures were in the upper 60s and lower 70s with dewpoints in the upper 60s. This aided in the development of uncapped s...
Flood — Feb 11, 2020
A stalled front across the region resulted in 4 to 6 inches of rain across parts of Northeast Mississippi over the previous couple of days. As a result, the ground was saturated and some flooding of roads occurred.
