Mesoscale Discussion 1667

1220 PM CDT Mon Jul 14 2025

Areas affected...VT/NH and western ME into eastern NY...western
MA/CT...northeast PA...and northern NJ

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

Valid 141720Z - 141945Z

Probability of Watch Issuance...20 percent

SUMMARY...Storms capable of localized damaging winds are possible
this afternoon.

DISCUSSION...Convection is gradually deepening early this afternoon
from western VT/ME into eastern NY and northeast PA. Continued
heating of a very moist airmass will result in MLCAPE increasing
above 1500 J/kg, and storm coverage is expected to increase with
time as a midlevel shortwave trough over western PA approaches the
region. Weak midlevel lapse rates will tend to limit updraft
intensity, but modestly enhanced mid/upper-level flow and effective
shear of 25-30 kt could support occasional storm organization.
Relatively large PW (generally 1.5 - 1.8 inches) may result in
localized downbursts with any stronger cells, while a few
outflow-driven clusters could evolve with time. The strongest
cells/clusters may be capable of producing localized damaging winds
through the afternoon.
