    A First Alert continues from our weather team Tuesday due to locally heavy downpours that will slow some during the evening commute and may cause localized flooding, especially in urban centers and poor drainage spots.

    Although damaging storms aren’t likely, it’s not impossible for Central and Southern New England to see an isolated gust of strong wind from one of the stronger downpours or thunderstorms. Overnight, the rain will gradually consolidate to Cape Cod and far Southeast New England, where rain will continue until early Wednesday morning.

    A cool and drying north-northeast wind takes hold Wednesday, delivering increasing sunshine with the most stubborn clouds over Cape Cod in the morning and high temperatures not surpassing the 70s, north-to-south.

    Thursday through Saturday will all feature a slow-moving disturbance to our west, raising the possibility for afternoon or early evening pop-up showers or thunder, but the highest chance will be found in Western New England.

    By Sunday, the chance of thunder grows regionwide, though an enjoyable day is still expected for most. High temperatures will gradually be rising through the period into the 80s by Sunday and likely to stay in the 80s with a return to our familiar summer pattern for all of next week in our exclusive First Alert 10-Day Forecast.
