– Start time projected 9pm – 1am Monday Night
– Extended period of snow, with wintry mix possible
– Best chance of sleet and freezing rain I-84 on south
– Snow/Mix tapers off early Tuesday afternoon
We’ve got our preliminary forecast in place at this time, but as we get closer to the start of the winter storm, we continue to get more data, and a more clear picture of how this storm might play out. This storm will push NE on Monday, but the radars early on Monday may look like the snow is about to begin… but the primary energy will linger back in the Tennessee valley, delaying the start time of this system.
We’ve continued to try and focus in on the snow/mix line, and where it will set up. The snow/mix line has steadily shifted south over the last day or so… taking the Hudson Valley from concerns of an extended period of freezing rain, to an extended period of snow, with some mixing possible.
The Tuesday AM commute is going to be a real mess, with a period of moderate snow likely, possibly mixed with sleet at that time. We would expect extensive school delays & closings, as well as very difficult travel conditions for those who must commute. Be sure to plan for a longer than usual commute on Tuesday morning. It’s possible this storm lingers long enough to cause issues for the PM commute as well. We’ll have to monitor the progression of the storm.
With regards to snowfall accumulations… latest guidance suggests the ranges from the preliminary forecast may be a bit low. For now, the preliminary forecast holds… but we would anticipate accumulations closer to the high end of the forecast ranges. That means accumulations of 3, 4 or 5 inches being common for much of the HV… if the guidance trend it correct.
We will continue to look at this overnight, and have our Final Storm Forecast in the morning on Monday. Have a nice evening!
