Areas affected...portions of NH and western ME

Concerning...Tornado Watch 520...

Valid 110129Z - 110300Z

The severe weather threat for Tornado Watch 520 continues.

SUMMARY...A severe storm or two remains possible in the short term,
but overall risk is expected to wane over the next 1-2 hours.

DISCUSSION...Instability has decreased over the past hour as the
boundary-layer begins to cool post-sunset and low-level inhibition
increases. While low-level shear may still support weak rotation in
the vicinity of the warm front, meager 0-3 km MLCAPE should limit
tornado potential as the boundary layer continues to stabilize this
evening. While a brief spin-up or strong gust is possible in the
short term, overall severe potential is expected to decrease with
time over the next 1-2 hours. As such, Tornado Watch 520 may be
allowed to expire at or before 04z.
