While there was a break from the rain with some sunshine for a good part of the afternoon, there is still the ongoing risk for more showers and a few strong-to-severe thunderstorms through mid-evening. Not all of Long Island will get storms. The best chance will be in Nassau County and western Suffolk County.

While parts of Long Island will just end up with scattered showers or a brief downpour, if a strong thunderstorm develops near you - there can be some damage. Damaging wind gusts, heavy downpours, low visibility, frequent lightning, hail and even a low risk of a tornado remain possible until the threat of storms diminishes after 8 p.m. or 9 p.m. Overnight, clouds and a few showers will be possible, but the threat for strong storms will be over for the time being by then. Thursday morning will be our next chance for heavy thunderstorms after this evening.
