Significant Weather Weekly Outlook Updated
Very warm and humid conditions are expected Thursday and Friday across southern New England but not to the extreme extent as last week. High temperatures in most areas will likely be in the mid 80s to lower 90s with dewpoints in the upper 60s and lower 70s. This will result in elevated heat indices in the mid to upper 90s, but probably not reaching heat advisory criteria.
A weak upper-level pulse of energy may trigger a few thunderstorms Thursday afternoon and evening. Although any thunderstorms may contain dangerous lightning and heavy downpours, the risk for damaging winds or hail (i.e., severe weather) looks to be low.
An approaching cold front will likely trigger scattered showers and thunderstorms in the warm, humid, and unstable air mass across southern New England Friday afternoon and evening. Any thunderstorms will contain dangerous lightning and likely heavy downpours. The risk of severe weather appears to be relatively small, although cannot totally rule out an isolated thunderstorm or two with damaging wind gusts. The air mass is relatively unstable with moderate wind shear, but mid-level lapse rates look to be fairly modest. There looks to be greater and deeper instability over the mid-Atlantic region. Nevertheless, an old weatherperson adage is to never rule out the possibility of a strong thunderstorm when a cold front moves through an unstable air mass.
The weekend looks to feature a lot of sunshine, high temperatures in the upper 70s to mid 80s, and low humidity. Conditions look favorable for any summertime outdoor activities for this weekend.
