A cold front passed through the region overnight, sweeping the late season humidity out to sea and ushering in a far more autumnal feeling air mass.
A south and southeasterly flow of air during the second half of the work week gradually pushed dewpoint values into the 60s, yielding a muggy feel to the air Thursday, Friday and Saturday. The muggy feel was accompanied by a rather gross weather day on Saturday as showers and areas of drizzle moved in and out of the region throughout the day.
However, winds shifted to the northwest after dark and the frontal zone passed the area during the overnight hours, abruptly sending temperature and dewpoint values downward.
The result: a much more October-like feel to our Sunday around the area. Expect fresh west winds to persist through the day, temperatures to top out in the lower to middle 60s and the air to have a far more cool/crisp feel versus the last several days.
