Many of the lower valley locations across the area saw temperatures below zero overnight and this morning. The lowest was the 8.1 below zero at the Warwick DEOS site this is the 2nd coldest reading in station history behind only last January 22nd with a low of 9.1 below zero. The West Chester DEOS recorded it's coldest temperature in station history when the mercury fell to 1.9 degrees below zero this morning. Both stations have records back to 2012. We should see temps get close to freezing this afternoon and even milder tomorrow with highs near 40 degrees to melt some of the snow cover. The milder air is a one-day event as colder air moves back in tomorrow night setting the stage for what could be a major winter storm beginning as early as late Saturday or early Sunday morning. Snow may last into Monday morning before tapering off.
