Mesoscale Discussion 1507

1207 PM CDT Sun Jun 29 2025

Areas affected...southern Appalachians into the Mid-Atlantic Region

Concerning...Severe potential...Watch unlikely=20

Valid 291707Z - 291930Z

Probability of Watch Issuance...5 percent

SUMMARY...A threat for sporadic tree damage due to thunderstorm
downbursts will increase this afternoon as thunderstorms develop. A
watch is not anticipated.

DISCUSSION...Thunderstorms are developing this afternoon within a
continued warm, moist, and uncapped airmass. Deep-layer shear and
tropospheric flow will remain rather anemic leading to slow moving thunderstorms whose motion will be driven primarily by cold-pool
interactions and terrain features. Precipitable water values across
the area range from about 1.5 inches in the higher elevations of the Appalachians to about 2 inches in the Chesapeake Bay area. The
combination of slow storm motions and high-precipitable water may
yield isolated, water-loaded downbursts capable of producing
sporadic tree damage. Given the isolated nature of the threat, a
watch is not anticipated.
