We've officially entered the time of the year when we are concerned about humidity. It can have a profound impacts on how we feel on a given day. If you're a true diehard fan of Summer, chances are you LIKE high heat and high humidity. If you're like me, however, you like it as comfortable as possible.
When trying to figure out how humid it is going to be, look at the direction the wind is coming from. If it's from the west, northwest, north or northeast, chances are a drier airmass will be in control and dew points will be in a comfortable place. If there's ANY southerly component in the direction of the wind, the opposite is true. In the Summer we often get broad areas of high pressure near Bermuda. Winds shift out of the southwest and really pump in the moisture from the gulf.
