High pressure continues to build throughout the eastern part of the country making people swelter as high temperature records are being challenged.

With the center of high pressure over the Carolinas, hot and humid air is being pumped across the region. But during the day tomorrow, winds will be westerly or west northwesterly and that will keep dew point temperatures from getting out of control BUT air temperatures are a different story. Because of the wind direction in this air mass, we might find Washington’s high temperature record broken and broken by several degrees. The air will not be dry…in fact it will feel a couple degrees warmer than what the thermometer indicates. An isolated thunderstorm or two could pop up in the afternoon. On Friday, with approach of a cold front and increasing cloudiness, temperatures will be held in the lower 90s. There will also be 60% chance for afternoon and evening showers and thunderstorms. Drier but only slightly cooler air will arrive for the weekend.
