holy smokin hot batman

ummm… did mother nature leave the oven door open or something?!

the northeast, and probably lots of other places around the world, have been experiencing a typical summer heat wave

hi heat wave, its me Mel, feel free to dissipate whenever you feel like it!

the thermometer in the shade outside of my house has been flexing around the 100 degree mark all day… and that’s without the heat index calculated in!

heat index, we hear this buzz word, use it all of the time in the summer especially, but do you really know what it means or how to determine what it’s supposed to be?! i def throw it around like its going out of style and rely on the weatherman to give me an accurate number so i can really sound like i know what im talking about :0) even though i had no clue, UNTIL NOW, as to how to get it… sound familiar?

here’s the scientifical-ness:


\mathrm{HI} = c_1 + c_2 T + c_3 R + c_4 T R + c_5 T^2 + c_6 R^2 + c_7 T^2R + c_8 T R^2 + c_9 T^2 R^2\ \,

and here’s the layman’s terms:

its an index that combines air temperature and relative humidity to determine the human-perceived equivalent temperature
developed in 1978 by George Winterling, adopted by the National WEather Service a year later, and derived from work carried out by Robert G. Steadman
it contains assumptions about the human body mass and height, clothing, amount of physical activity, thickness of blood, sunlight and ultraviolet radiation exposure, and the wind speed

    With these unusually hot temps on the Mid-Atlantic eastcoast, I can thorougly comprehend and appreciate my new daughter-in-law’s weather comments about her hometown, Phoenix, AZ – and to think at 106* here today, it’s just about the same there.

    So do I dare ask when is that next snow-storm?
