From OKX AFD:
Dry this morning, then expecting showers and thunderstorms to
develop with a pre-frontal trough and an approaching cold front
as it approaches later today. CAPE and shear will result in the
organization for thunderstorms today. There is decent amount of
CAPE in hail growth region. Specifically, RAP model is
conveying 0-6km bulk shear of 25-35 kt moving into the region
this afternoon with surface CAPE of around 1500-2000 J/kg.
There is a chance some of the storms become severe. Main
threats with these thunderstorms will be gusty winds, hail,
heavy rain, and frequent lightning.
There is a moderate risk of rip current development on the
Atlantic beaches today.

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/...
Evening starts off with the cold front right about to enter the
region. Bulk shear 0-6km maximizes in 30-40 kt early this
evening will allow for thunderstorms to remain organized but
decreasing CAPE will lead to some loss of strength to the
thunderstorms. Expecting the western half of the forecast
region to be numerous to widespread with showers and
thunderstorms and by the mid evening expecting this greater
coverage of showers and thunderstorms to spread to the eastern
half of the region if not shortly before. Same threat with
thunderstorms before in the afternoon but again do expect a
little weakening with the lower amounts of CAPE for Southeast
Connecticut and Eastern Long Island where temperatures will be
lower with the greater maritime influence.
