Thunderstorms and heavy rain will slam the east coast early Monday evening. The storms will move slowly, impacting areas from New York City to Washington, D.C. and last into the evening hours. Low visibility may influence travel conditions during rush hour, especially on I-95. Boston may also be hit later in the evening.
Last weekend's high temperatures, heat and humidity are big factors in the formation of these storms. Even the heat throughout the day on Monday influenced these storms, as places like Washington D.C. saw temperatures as high as 104 degrees and Poughkeepsie, N.Y., hit 92 degrees this afternoon, only one degree below its record high from 2003.
