Low pressure, responsible for our Christmas Eve snow, will shift into southern New England on Christmas Day. As this happens, our snow will wind down shortly after sunrise after up to a couple inches of accumulation. Once the snow ends, the rest of Christmas will be dry as low pressure moves away from us.
Beyond Christmas, we continue to watch a storm system that is currently tracking east across the Rockies. This storm will head out into the Plains Christmas Day, drop into the Gulf Coast then make a turn to the northeast on Wednesday. This low will head into the Ohio Valley late Wednesday before a new area of low pressure develops over the mid Atlantic states and takes over, becoming the primary low as it heads along the Northeast coast.
While this is happening, plenty of moisture will be moving north as well and will wrap around the low into central New York. We are still concerned that the lower atmosphere might become warm enough for some mixed precipitation (mainly sleet) but trends from our computer models today point to areas south and east of Syracuse as the most likely candidates for snow to mix with sleet. All of central New York is under a Winter Storm Watch for later Wednesday into Thursday with the potential for 6 or more inches of snow. If you have any travel plans in the Northeast or Mid Atlantic states midweek you’ll want to keep close tabs are where this storm is headed and stay tuned for more updates.
Low pressure moves off the New England coast Thursday night and our weather quiets down on Friday. However, a new area of low pressure will head toward the East Coast later Saturday. That system has the potential to bring another shot of widespread to central New York.
