Forecast Highlights:

April 15, 2014 Storm Updates

Occasional storm updates on today’s storm will be posted below, ranging from rain, wind and thunderstorms during the day to cold temperatures, snow and sleet in the evening.

 

12:45 AM: Snow, Sleet Continue

nerad254As of 12am, the cold front has already tracked offshore, with a strong cold air mass surging into the region; precipitation remains slow to depart, however, with precipitation type primarily as snow and sleet for most locations except for central-eastern LI/CT which are gradually starting to mix with sleet. A particularly heavy band of precipitation is situated over NE NJ and NYC, but with sleet rather than snow reported under this band. Most locations north and west of NYC so far have seen generally up to an inch of snow, with locally higher totals towards interior NW NJ/SE NY. Despite temperatures having peaked in the 70s and 80s as recently as yesterday, the sharp drop in temperatures along with the snow/sleet mix is leading to hazardous road conditions with wet snow and ice. Snow has mostly ended in NW NJ and Orange county, with the back end of the precipitation shield to continue gradually shifting east, reaching NYC by at least 2am and LI/CT by 3-4am.
