Excessive Rainfall Risk Outline for Friday through Sunday
Severe Thunderstorms Expected from the Arklatex Region to the Tennessee Valley on Saturday
Strong to severe thunderstorms are expected to develop on Saturday. Instability and wind shear will increase throughout the day resulting in the intensification of ongoing thunderstorms and further development along the cold front. Hail, damaging winds, and tornadoes will all be potential hazards with these storms. A few strong tornadoes cannot be ruled out with the highest tornado threat across Arkansas and western Tennessee.

SPC Convective Outlook for Saturday
A Look Ahead
An area of low pressure will track from the Central Plains toward the Northeast on Wednesday. This system’s associated warm front will lift northward into the Mid Atlantic and its associated cold front will track across the Mississippi River Valley by Thursday. To the south of this warm front, and east of the cold front, multiple rounds of rain and thunderstorm activity are anticipated. At this time, model guidance suggests widespread rainfall amounts of 1-3 inches with locally higher amounts in excess of 4 inches will be possible across portions of the Tennessee River Valley and the Southeast on Wednesday and Thursday. This will allow the flooding and flash flooding threat to continue.
