based on that definition, the wet bulb temperature seems to be same as the dew point?

No....LB

The dewpoint temperature is the temperature at which the air can no longer "hold" all of the water vapor which is mixed with it, and some of the water vapor must condense into liquid water. The dew point is always lower than (or equal to) the air temperature

ah okay!  So the wet bulb only equals the dew point when the relative humidity is 100%, at which point they both intersect with the actual temperature!

 

wait, I reread the definition for wet bulb you posted and it is also always either equal to or lower than the actual temp?

 

can wet bulb be used in place of dew point for heat index calculations?

Snow weenies want maxed out totals..but today is not the day for fun and games...

Indeed this is why you dont drive today.

The most accidents happen in low snowfall totals (under 1") and in icy conditions.
