Discussion
*The coldest night of the season so far is on its way and many suburban locations will experience a frost/freeze for the first time this fall.* October was a warmer-than-normal month in the Mid-Atlantic region (PHL +5.8 degrees, DCA +5.5 degrees, NYC +4.1 degrees) and overnight lows rarely, if ever, dropped into the 30's in most suburban locations...that will change not only later tonight, but also during the next few late nights as well. An upper-level disturbance can produce occasional showers around here today, but skies should clear this evening and colder air will push into the region following the passage of a secondary cold frontal system. Temperatures should stay below-normal right through the upcoming weekend.
