Snow Arrives Overnight Blizzard Warning Suffolk County

The radar shows snow beginning to spread into Western Pennsylvania and you can see the comma shape of the structure of the echos. This is a sign of a powerhouse system in the upper layers of the atmosphere. Everything seems on course here for a snow of 6 to 12 inches for much of the area and 12 inches or more in the blizzard warning area.

Now that we are in the short range, we can use the HRRR model and its presentation of the weather system is consistent with all the other models. The HRRR model below shows the snow totals through 11am on Thursday and obviously there is more snow to go before the storm comes to an end during Thursday afternoon.

When we look at the surface map you can see the well defined storm offshore and the back edge of the snow at 11am is still back in Western New Jersey. This means that Long Island and Connecticut should see their amounts from here and smaller increases to the west.

From the standpoint of snow storms, this will not compare to last year’s blizzard. The speed of movement prevents this from becoming a 2 ft snow producer so amounts will be half of what the Blizzard of 2016 produced. However at least for a number of hours tomorrow, the snow will fall hard with the likelihood of a few thunderstorms in the mix as well. Temperatures will settle in the 20s during the storm and fall to the mid teens to single digits Friday morning.  Friday will be dry with some sunshine and arriving clouds with highs in the 20s to near 30.

The maps below are the National Weather Service forecast snow maps with the most likely snowfall prediction.
