Damp Night, Improving Sunday

Tonight through tomorrow we'll continue with about a 30% chance of showers, diminishing in the afternoon. Travel carefully through early morning due to fog that may be thick in spots. Lows will be near 60 and highs tomorrow reach 70, although inland counties will stay in the upper 60s. Midday tomorrow a weak cold front will move south across the area finally ending the showers but not totally getting rid of the clouds and humidity.

Usually this time of year the air is so dry that static cling is a big deal. That's not so, lately. We've stayed mild with high dew points creating high relative humidity. To put it simply, it's been a bunch of bad hair days. Human hair responds to increased moisture in the air by changing length. Most people think that hair shortens when it is humid but in reality it lengthens a little. The end result is it goes out of control!

In fact, human hair has been used in hygrometers at least back to the 1800s. A hygrometer is an instrument that measures relative humidity. Horse hair and other animal hairs have been used too. It may not sound very scientific but it's fairly accurate in the true definition of "relative" humidity. See more about how that works here.

Oils and conditioners help give your hair control because they interfere with the normal reaction of hair to humidity. For you that's a positive. Your hair will get a break soon and that's no tease. After a few showers and high humidity tomorrow the air dries out for Monday and Tuesday, with temperatures staying in the 60s.
