StormTeam10: Record setting humidity

Mid 70 degree dew points are typical in July, NOT late September!

Although it has been unseaonably humid all week Wednesday marked the highest level of humidity of this stretch AND it also set a record.
The easiest way for us to measure and track humidity is via the dew point. Simply put, the dew point is a measure of the amount of moisture in the air. The higher the number, the more moisture the air can hold...on warm days with a high dew point we can't cool off easily...sweat stays on our skin and doesn't evaporate like it does on a dry, cool day.

Wednesday afternoon the dew point reached 75 degrees at TF Green, the official climate station for the state of RI.

This was the highest dew point measured on September 27th, since records began back in the early 1930s...as you can see from the chart below, a dew point in the mid 70s is rare and those of us who have lived here for a long time know that this is some unusual humidity for early fall!

It's this warm, humid air that has created all of the dense fog the last several nights...and once again we will see another night with locally dense fog:

The good news, for those of you who are longing for some nice, crisp fall air...it arrives later Thursday afternoon and evening. In fact, as you look at our 7 Day forecast, check out the night time temps over the weekend...many areas will dip into the 40s!

Gotta love our up & down New England weather...thanks for reading, Mark
