A shortwave will bring a weak boundary through the region late Wednesday morning triggering some showers in the region. Low level moisture will remain relatively high throughout the day with dew points 45 to 50 and RH above 70%. Current forecast soundings indicate low CAPE (generally under 500 J/kg), however there will be a weak cap, and mid level cold air advection could assist in some thunderstorms with small hail particularly in New York state, but not ruling out convection reaching New England. Latest WRF radar simulation forecast indicate a line crossing Keene around 8pm tomorrow.
