Discussion

Low pressure over New England during the past couple of days has helped to pull cool air into the region from our northwest at the same time it has inundated parts of Maine with several inches of rain. The influence of this low pressure system will diminish during the next couple of days as high pressure builds in from the middle of the country. This action will help to cause an expansion of the hot bubble of air that has been confined to the Rockies and Plains into the Middle South and into at least the southern half of the Mid-Atlantic region (e.g., DC metro region) by the end of the week. We will be on the northern periphery of the real hot air mass on Friday and Saturday and, in that position relative to the high pressure area, thunderstorms could be a threat here as they will tend to rotate around the center of the high pressure system centered to our southwest, and the hottest weather should occur south and west of here (e.g., DC region).
