Fall means that you’re not sweating as much and you’re not having to take two or three showers a day (which will lower your water bill, too). The National Weather Service forecasts our humidity Monday morning at 69 percent. That means your hair probably won’t spontaneously curl and your glasses won’t fog. And unlike the very recent past, no days this week are forecast to reach 90, with mostly clear sunny days through Thursday and 20 to 30 percent of showers over the weekend. Today’s high is expected at 86.
