1208 PM CDT Tue May 21 2024

Areas affected...Adirondacks into Parts of northern New England

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

Valid 211708Z - 211915Z

Probability of Watch Issuance...20 percent

SUMMARY...Damaging winds and isolated marginally severe hail may
occur this afternoon. Clustering of storms may lead to locally
greater wind damage potential. A watch is not expected.

DISCUSSION...Morning observed soundings from CAR/GYX showed
mid-level lapse rates approaching 7 C/km. With an approaching
MCV/shortwave from Great Lakes region convection last evening, some
increase in storm coverage is expected to occur this afternoon.
Effective shear will only be modest (25-30 kts), but a few more
organized storms/clusters appear possible. Damaging winds and
marginally severe hail will be the primary risks with this activity.
Should storms cluster, locally greater potential for damaging winds
would exist especially where low-level lapse rates have steepened.
