Cold Through The Weekend Snow Sleet Freezing Rain Possible

Late Saturday Early Sunday

We are at least catching a breather on Long Island as we have no snow in the forecast for tonight right through the daytime Saturday. A disturbance is passing by well to our south off the Virginia coast so skies will partially clear tonight. It will be cold though with lows in the upper teens to around 20.

Radars have gone nice and quiet across our ara on the regional radar while the Mid Atlantic regional radar is seeing areas of snow sleet and freezing rain. Precipitation is moving to the east and it will be all offshore by Friday morning.

Two cold days are ahead with some sunshine north and clouds south on Friday. Highs will be in the upper 20s to near 30. Then it is back down to the mid to upper teens Friday night into Saturday morning.

Saturday begins a set up for the next storm system that will be heading our way. This low will pass to the south and east. Weather models show a rather weak system here but what is more important is how much precipitation it will produce and the state of the lower atmosphere when that precipitation arrives later Saturday and continues into Saturday night.

An early look at forecast temperatures at 4pm Saturday shows temperatures in the 20s just about everywhere except right along the immediate coast. Those temperatures don’t change much overnight as we see readings barely budging. All of this will be during a time when precipitation will be overhead.

A quarter to perhaps a third of an inch of liquid precipitation is indicated for Saturday night and with a nose of warm air pushing in at about 500 ft, it is likely that we will see some freezing rain and some sleet.

It would be enough to cause icing over a large area of the Northern Mid Atlantic to Southern New England. With temperatures close to critical levels it makes it had to figure how much snow falls in all of this. The ideal solution would be snow or sleet with any freezing rain on top of that. Freezing rain from the get go would be far worse and more dangerous outcome especially for roadways. The ice forecast for Long Island is an early one with amounts under a tenth of an inch of ice accretion forecast but expect this to change over the next couple of days.

Lingering clouds and lingering areas of sleet or freezing rain will be around in some areas into Sunday night. The next storm system will be revving up for Monday night and Tuesday. Low pressure will attempt to go north up the Appalachians before a secondary develops and takes over. How fast that secondary forms will be key to this potential snow sleet freezing rain event. This system does look to be stronger than the one for Saturday night as there is a sharp short wave trough that is supporting this system  Another storm lies in wait for later next week.
