Stifling heat and humidity will spread eastwards into the Ohio Valley and the Great Lakes on Thursday then extend into the mid-Atlantic coast on Friday.
Hot conditions is nothing new in July, but temperatures crossing 100°F is unusual from Chicago to New York City so far this century. The last instance when the temperatures crossed the triple digit in New York City was in 2010 and 2011 for two days.
Partly cloudy skies with a couple of thunderstorms will prevent the temperatures crossing the triple digit mark across the northeast during the upcoming heat spell.
Cities like New York City, Philadelphia, Pittsburgh, Baltimore, Washington D.C., Richmond and Charleston, West Virginia, can expect a heat wave which might last for three days in a row having 90-degree highs.
The combination of heat, humidity and strong sunshine will make it uncomfortable for the people in the region. This might prove dangerous for the health of the people as chances of respiratory and/or cardiovascular problems, anyone who overdoes it in the heat can lead to dehydration, heat exhaustion or heat stroke. People have been advised to drink plenty of fluids.
This spell of heat will continue or might intensify next week. For much of the Mid-Atlantic there will be a long stretch of typically warm and humid conditions during July.
