Mesoscale Precipitation Discussion 0523

655 PM EDT Thu Jun 26 2025



Areas affected...Southern & Central WV...Southwest VA



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



Valid 262255Z - 270300Z



SUMMARY...As rounds of slow moving strong thunderstorms continue

to flare up this afternoon, additional areas of flash flooding are

possible. Areas along steep terrain are most at-risk, as well as

in low-lying valleys.



DISCUSSION...Thunderstorms flaring up across southwest VA and

southern WV have had a history of producing Excessive Rainfall

rates with some elevated streamflow magnitudes evident in and

around the Radford, VA area. The environment remains favorable for

at least several more hours with mesoanalysis showing MLCAPE

values between 1,000-2,000 J/kg and PWs of 1.7-1.9" for much of

the highlighted area. These storms are also feeling the effects of

a rather strong ESErly 200mb jet located over the Carolinas. These

winds are unusual in terms of both strength its direction (ESE)

which may be allowing for enhanced upper-level divergence over the

region. Additional thunderstorm development will be largely due to

outflow boundaries and congealing cold pools. The lack of

sufficient vertical wind shear should keep these storms relatively

short-lived (1-2 hours generally), but given the environmental

parameters and some synoptic-scale support aloft, as much as 2-4"

worth of rainfall could occur within the next few hours within the

more intense storms. With that said, additional flash flooding is

possible for the remainder of the afternoon and into this evening.

Areas most at-risk are within low-lying valleys or along steep

terrain.
