Forecast Discussion: High pressure over Maine continues to give eastern Massachusetts clear skies for this evening, and mostly sunny skies Saturday morning. However, the sunny weather we have experienced the last several days will be coming to an end. A warm front moving into Quebec, Canada will bring more humid air into the region Saturday. As we go through the holiday weekend, I would not call Saturday and Sunday a washout for the final barbecue. However, be aware that there will be isolated showers and thunderstorms possible, especially in the later half of the day. By Monday, a cold front will pass over us, giving us the best threat for precipitation. We will definitely see some showers and thunderstorms Monday night and Tuesday morning, before a high pressure ridge builds over us in the afternoon. We will see drier weather on Wednesday. From there, my overall confidence in the forecast is extremely low. There are too many factors at the moment, including the track of Tropical Storm Lee once it makes landfall. Also, we are still watching Hurricane Katia in the Atlantic. If Lee’s moisture is picked up along the front, we may see more precipitation right into Thursday.
