I'm sure this is somewhere within the August 2019 discussion thread but I don't feel like reading through all of the temp and dewpoint crap and about how people who live in forests try to use their weather to quantify a regime and how people on tarmacs try to quantify their weather as a regime so here it goes...
The next few days offers up several opportunities for convection and like we saw this weekend the meso-models (or CAMS) are going to have a very difficult time grasping the evolution of convection.
Today:
Moderate (to even borderline extreme) instability in place thanks to very high dewpoints, rather warm sfc temps, and modest mid-level lapse rates. Shear isn't overly strong (but a modest MLJ of 40-50 knots) punching into the region will help create bulk shear values supportive for organized convection. The verdict: Scattered severe t'storms today which will produce localized areas of wind damage. Transient supercells may also produce some large hail with low risk for a tornado up in ME.
Tuesday:
Weak shortwave approaching, high humidity, and low CIN will result in scattered t'storms developing during the afternoon with isolated svr potential
Wednesday:
Wednesday is a bit more intriguing with strong front/shortwave energy approaching, and decent wind shear/instability. Could see scattered severe weather with all severe hazards possible.
