Report by Paula Antolini, February 11, 2019, 1:09PM EDT
The National Weather Service has issued a Winter Weather Advisory for southern Connecticut, northeast New Jersey, southeast New York and other areas.
A wintry mix of precipitation, which may begin as early as late Monday night, is expected Tuesday and Tuesday night. There is a chance that the combined amount of snow, sleet and freezing rain reach levels that would eventually warrant a warning.
Snow begins toward daybreak Tuesday morning for the NYC metro, and then works northeast across the remainder of the area. Potential high impact for the morning commute.
Precipitation transitions to a wintry mix during the late morning and afternoon hours from south to north. There is some uncertainty with how quickly this transition occurs. Small timing differences will have significant impacts on snowfall and ice totals.
Snowfall totals of 1-4 inches along the coast and 4-7 inches inland are forecast before changeover. Highest amounts in the watch area.
A light ice accretion near the coast with a tenth to quarter inch well inland.
Rainfall amounts of 1 to 1 ½ inches with locally 2 inches.
*****
SNOW: Late Monday Night through Tuesday afternoon. Precipitation will transition over to rain at the coast by late afternoon/early evening with gradual transition through the night across the interior.
FREEZING RAIN: Ice accumulation of a tenth to quarter inch inland with a few hundredths elsewhere. Falling power lines and tree branches possible. Interior NE NJ, the Lower Hudson Valley and interior Southern CT, Lighter amounts elsewhere. Tuesday Afternoon through Tuesday Evening.
HEAVY RAIN: 1 to 1 ½ inches, locally 2 inches. Minor Flooding of Urban Areas, Low-lying Roads, and Small Streams and Creeks. Entire Tri-State Region. Late Tuesday Afternoon through Tuesday Night.
