A minor to moderate heatwave is affecting parts of the U.S. today through the weekend, driven by a subtropical ridge of high pressure that is raising temperatures 5 to 10 degrees above normal. The weekend weather is expected to be dry and bright with a mix of sun and clouds, and temperatures will climb slightly. Inland areas will experience the warmest conditions. However, a wind advisory has been issued for Cape Cod and the Islands, where breezy conditions will persist. Earlier in the day, showers over southeastern Massachusetts and Cape Cod diminished, leading to a dry and windy afternoon with some sun breaks expected across interior Massachusetts, Connecticut, and Rhode Island. Next week may bring a shift in weather patterns, including a prolonged period of inland monsoon thunderstorms and the possibility of much-needed rainfall in some locations.
