Areas affected...northeastern New York into Vermont

Concerning...Severe potential...Watch unlikely 

Valid 121545Z - 121815Z

Probability of Watch Issuance...20 percent

SUMMARY...Isolated strong to severe storms cannot be ruled out this
afternoon from northeastern New York into Vermont. A brief/weak
tornado or locally strong gusts will be possible.

DISCUSSION...Visible satellite shows areas of clearing, which is
allowing for relatively warm conditions to develop. Surface
temperatures are already in the upper 60s F, which is warmer than
several models indicate. This has led to the development of several
hundred J/kg SBCAPE.

Area VWPs show 0-1 SRH over 200 m2/s2, which is quite supportive of
rotation within storms. This, along with a relatively high RH
boundary layer, and lift ahead of the front/surface trough, suggest
an uptick in at least low-topped thunderstorm coverage may occur.
Whether individual cells form, or north-south line segments, storms
may acquire sufficient low-level rotation for a brief tornado risk,
within a small zone where heating is most prominent.
