NYC METRO INCLUDING NORTH JERSEY L.I. CT
As this cold front will be passing through tonight and then stalling out to our south we feel we have enough in front of us to begin looking at the weekend and the chances for snow. Right now it appears that the coast will be grazed with some precipitation late Friday night into Saturday morning and it will likely be snow. It appears that any snow will be confined to the immediate coast which means Coastal New Jersey mainly east of the Garden State Parkway to about NYC, Long Island and possibly Coastal Connecticut. North and west of that line it is likely that we will see just clouds and no snow at all. However let me caution that we have seen several situations in the last month where models shifted northwest at the last minute. The day before Thanksgiving comes to mind along with a few others.
There is still uncertainty here and enough room for this to go in either direction. What we have is a lot of energy running around in both the northern and southern part of the jet stream . The southern energy is responsible for the wave that is going to develop. Weather models have been slower and deeper with this short wave trough. It has slowed enough than the northern stream energy is getting closer to it. It is not impossible that the system in the south could be a bit slower and the one in the north could be a bit faster. If that happens then we would see the back edge of the precipitation shield pulled further northwest...READ MORE ATÂ http://www.meteorologistjoecioffi.com/index.php/2017/12/05/snow-possibility-late-friday-night-saturday-coast/
