If the Weather Service forecast is right, today will be the hottest day of the year. There's been three days, including yesterday, where the high has reached 92 degrees. The NWS is forecasting a high of 94 in the city today. The Weather Channel and AccuWeather don't see us getting that warm. Then again, AccuWeather said yesterday's high would be 85.
The combination of heat and humidity are going to fall a bit short of the mark needed to declare a heat advisory. Nevertheless, the Weather Service has a great introduction to the dangers excess heat poses to the body and tips on how to beat the heat.
Among the wisest recommendations is to slow down. That advice will also help you avoid breathing problems. The state Department of Environmental Conservation has issued an Air Quality Health Advisory effective until early tomorrow morning. Watch out for those fine particulates!
Also of note today. Showers and thunderstorms, some possibly intense, as a cold front makes its way south. The cold front will bring us dry air but no cool air tomorrow. Expect highs in the lower 90s again. More seasonable temperatures arrive on Sunday.
