High pressure will dominate the Northeast region Sunday and allow for beautiful weather to close out the weekend. Humidity will remain low and high temperatures Sunday will be very similar to Saturday. As high pressure sinks southward into the mid-Atlantic Monday, southwest winds will usher in higher humidity. A strong ridge of high pressure aloft will be anchored over the central part of the country through the middle of this week.
Disturbances will ride over the top of this ridge across Ontario and Quebec provinces and into the Northeast, providing the focus for showers and thunderstorms to move across the area on occasion Monday through Wednesday. Clouds will gradually increase on Monday. Showers and thunderstorms will likely hold off until Monday evening at the earliest, and may not get into the area until Monday night. The threat for showers and thunderstorms will continue into the day on Tuesday and it will be warm and humid with dewpoints in the upper 60s. A cold front will approach Wednesday and bring the threat for more showers and thunderstorms.
