Heat Wave Brewing

The temperature today at Bradley International airport reached 89 degrees. So today will not fall within heat wave criteria (three or more days with temps 90+). But don't fret! We have five days in a row of 90+ degree heat on the way! I included a computer model for your viewing pleasure above. I highlighted the daily high and low temperatures in yellow. Yeah...triple digits are possible by Friday.

Two rows below temperature, you can find the dewpoint. Whenever the dewpoint is above 70 degrees, the air feels soupy, uncomfortable, steamy and oppressive. Notice tomorrow the dewpoint will drop and remain at comfortable levels through Wednesday. But Thursday and Friday...WOAH. Dewpoints in the low 70s?! Not fun. For those days the combination of high heat and humidity will send heat indices into the triple digits. The heat index is a measure of how hot it feels when you're outside (much like the wind chill in the winter). The Frizz Factor for those days will be an 11....on a scale of 1-10.

I stole this chart from a website. You can find lots of different charts out there. But this will give you a rough idea of how the dewpoint affects your comfort level.
