An approaching low pressure system will spread rain showers from south to north into eastern New York and western New England late Friday night into early Saturday morning.  Temperatures are expected to be near to just above freezing at the onset of precipitation early Saturday morning, so a brief period of sleet and freezing rain is possible, which could result in slippery spots on untreated surfaces.  The most likely time frame for any possible frozen precipitation is 4-10 am Saturday, with plain rain showers likely during the afternoon and evening.
