80 Degree Dew Point Days

Posted: 21 Jul 2017 05:34 AM

Dew point temperatures got a bit excessive on Thursday with a number of observation sites in the state reporting 80+ degree readings. The featured map presents an analysis of long term hourly observation sites for the average number of days per year that the dew point reaches at least 80 degrees. The areas immediately near the Gulf of Mexico, Gulf of California, and Atlantic Ocean waters see the highest readings as water temperatures near 80 will help support such humid dew points. In Iowa, we get the transport of humid air from the south and the enhanced crop transpiration this time of year to help us reach 80 degrees.

Good = 13
Bad = 1
Abstain = 1
