Nice have the 3k Nam on board . Probably a spin or two pike region to 84
On the severe-storm potential, much of Southern New England is
highlighted in a Marginal Risk for severe. Mid-level lapse rates
look fairly weak and is a limitation. Progged CAPEs are on the order
of 1500-2500 J/kg, with bulk shear around 35-40 kt. SPC`s SREF
Craven-Brooks severe index parameter highlighting solid
probabilities for values at or over 10,000 units, which can favor
strong/severe storms. The 12z HREF continues to show some 2-5 km
Updraft Helicity swaths as well, though mainly across central and
eastern MA. Though the primary severe threat would be from strong to
locally damaging straight line winds, if a weak surface wave low can
lead to locally backed surface winds it could yield a very low-prob
tornado risk but the threat is conditioned upon that occurring. The
NAM-3 km hints at this more than other models with 0-1 km shear of
20 kt/0-1 km SRH 100-150 units in parts of the interior.
