WEATHER NEWS: PM Update: Some fog overnight. Increasing heat and humidity on Monday.


Don’t be too fooled by the addition of the radar to today’s update. Most of us will stay dry, but a few “lucky” locations will get wet from isolated showers. Skies will clear out overnight, but you may not notice since areas of fog are likely to develop in the predawn hours. Once that fog burns off by tomorrow morning, Monday will be a hot and humid day, with the heat index near or above 100 degrees.

Through Tonight: A few isolated showers are possible before sunset. Otherwise, skies will clear this evening and overnight. Muggy conditions continue, with temperatures in the low 70s and near 100 percent humidity. Areas of patchy fog are likely to develop given the moist atmosphere and lack of wind.
