Areas affected...Pee Dee region of South Carolina into far

southern North Carolina



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



Valid 022057Z - 030057Z



SUMMARY...A localized threat of flash flooding is expected to

continue through this evening across parts of the Pee Dee region

of South Carolina and far southern North Carolina, including the

Cape Fear region. Training thunderstorms with rates up to 3"/hr

and rainfall totals up to 4" are possible, potentially leading to

instances of flash flooding.



DISCUSSION...Latest radar imagery and surface observations depict

repeating thunderstorms over eastern SC and far southern NC

associated with an area of surface convergence ahead of an

approaching cold front. This area of convergence is also being

aided by a sea breeze denoted by GOES19 visible imager over SC,

which should continue to be oriented parallel to 850mb flow over

the next few hours and add to the training thunderstorm potential.

Hourly rainfall rates have been estimated by MRMS as high 3" and

when combined with the repeating nature of cells could lead to

isolated flash flooding concerns. Even though the region is known

for its sandy soils and high FFG (1-hr FFG of 2.5-4.0"), some

localized totals of 4" could lead to isolated instances of flash

flood. This is of particular concern in low-lying or urban

locations.



PW values per SPC's mesoanalysis remain above 2" and as high at

2.4" in eastern NC, with MLCAPE values in the inflow region of

central SC greater than 2500 J/kg. This environment supports the

19z HRRR depiction of 3-hrly rainfall amounts possibly exceeding

3" and nearing local FFG.
