Mesoscale Precipitation Discussion 0226
NWS Weather Prediction Center College Park MD
424 PM EDT Sun May 24 2026

Areas affected...Southern Georgia

Concerning...Heavy rainfall...Flash flooding possible

Valid 242024Z - 250130Z

SUMMARY...Repeating thunderstorms bring isolated flash flood
threat to southern/central Georgia into the evening. Rainfall
rates of 2-3 inch/hr will continue with localized maximum totals
of 3-5 inches for this area which is not flood prone.

DISCUSSION...Regional radar and satellite imagery depict an
east-west oriented line of scattered heavy thunderstorms
developing on low level convergence over southern Georgia with
further upstream development in far north Florida. Instability is
robust with SBCAPE of 3000 J/kg and moisture is extreme with 2.2
inch PW (2.5 sigma above normal) supporting highly efficient
convection with high rainfall rates of up to 3 inches/hr.

Recent hRRR and RRFS runs are on the lighter side for rainfall
compared to radar estimates. Fair rates of northward movement will
continue with SSWly deep layer mean flow generally around 20kt.
However, the additional upstream development and cell interactions
make a concern for localized maxima of a quick 3-5 inches of
rainfall in the coming few hours which would exceed the general
flash flood guidance near 3 inch/hr. This activity will continue
moving north and could bring concerns this evening to more
sensitive areas such as Atlanta and areas of northeast GA into SC
which have seen more rain in recent days due to the persistent
cool air damming.
