Reference recently issued Mesoscale Precipitation Discussion 0014 for short-term details on flash flood potential from far southeast Louisiana northeastward to western Georgia. Main change to the outlook is to trim on the western and northern edges of the Marginal Risk area where most of the risk of deep convection has ended for the day. Flash flood potential will continue along a linear mesoscale convective complex moving eastward across the region. Some southeastward expansion of the Marginal was made in southeastern Alabama given potential for convection to linger through the afternoon hours - although the overall risk of flash flooding should continue to become progressively more isolated with time and eastward extent. Cook ...Previous Discussion... Update: Expanded the Marginal Risk area southwest from the initial issuance based on radar and satellite trends suggesting the risk of excessive rainfall will persist beyond 12Z. Confined the expanded Marginal risk along the axis of highest dew[point ahead of a cold front moving eastward. Signals still suggest a downward trend fairly early in the day. For additional details...refer to WPC Mesoscale Precipitation Discussion 0013. Bann Previous Discussion... Heavy rainfall should be on-goingacross portions of the Southern Appalachians as the Day 1 period. Some of that rainfall will be falling on at least partially saturated ground which has the potential to produce flash flooding. The expectation is that the threat for excessive rainfall should wane by 18Z today as the area of rain moves out of the region. Bann Day 2 Valid 12Z Sun Jan 11 2026 - 12Z Mon Jan 12 2026 The probability of rainfall exceeding flash flood guidance is less than 5 percent. Pereira Day 3 Valid 12Z Mon Jan 12 2026 - 12Z Tue Jan 13 2026 The probability of rainfall exceeding flash flood guidance is less than 5 percent.
