This morning features sunny skies across much of southern New England. For some down in Connecticut, it is welcomed for intense clean-up following yesterdays thunderstorms.
The solar heating we get this morning combined with dew points in the low 60's and a cold pool of air aloft will help destabilize the atmosphere for this afternoon. Expect showers and thunderstorms to develop by 1pm. 0C wetbulb height is around 9600 feet this afternoon, sufficient for small hail in some thunderstorms. With PWATs around 1.3", expect heavy downpours to accompany thunderstorms. Winds throughout the column are weak (15kt and under), so storms will be slow moving (generally around 15kt), increasing the threat for flash flooding.
Thunderstorms will dissipate later tonight with the loss of diurnal heating.
