With skies turning mostly sunny, expect a high around 92 today, with a southwest wind of 5-10 mph, and heat index values up to 100. Tonight will be mostly clear and 77, with a west wind around 5 mph.
Tomorrow will be mostly sunny, with a high around 101, a west wind around 5 mph, and heat index values over 110 likely when combined with dew points in the 70s. If the high temperature forecast verifies, it will be our first 100 degree day since July 22, 2011.
Regardless of whether we do actually hit 100 (which is likely) or fall just short with a 98 or 99 degree high (a little less likely), it will be an extremely hot day; avoid significant outdoor activity if possible, stay hydrated, and remain in air conditioned areas when possible. Remember the signs of heat exhaustion and heat stroke (see Weather Service visual below).
Tomorrow night will again be muggy and extremely warm, with a low around 77, mostly clear skies, and a west wind around 5 mph.
Sunday will be similar to Saturday, with mostly sunny skies, a high around 100, and heat index values over 110 likely at times. There is a slight chance of some afternoon thunderstorms, but the better chance for precipitation will be across northern New England.
Sunday night will be mostly cloudy and 72, with a chance of showers; Monday will feature a chance of showers, partly sunny skies, and a high around 83. Monday night could feature some showers, with a low around 66; Tuesday will be partly sunny and near 82.
Have a great day and stay cool!
