While still do expect some snow showers or even steadier light snow tonight, the pattern that has brought us the nearly continuous snowfall since late last week is finally showing signs of breaking down. Low pressure that has been parked off the New England coast will start to shift to the east and that will cut-off the flow of Atlantic moisture to central New York. In addition, after Tuesday morning, our winds will shift from the northwest into the northeast and that will take Lake Ontario out of the equation. Look for any snow showers (or freezing drizzle) still around for the morning commute to quickly come to an end.
Next, we focus on a storm system tracking from the northern Plains now to the mid Atlantic coast by Wednesday. Heavy snow will fall in the short term around Minneapolis and Chicago and by the middle of the week Washington DC will be the target for heavy snow.
The data we’ve looked at so far today points to this storm being too far south and east to be much of a factor for us here in central New York. A couple (but not all) of the computer models that we look at hint that we could get grazed by the storm on Wednesday, perhaps into Thursday. Since this is still a possibility, we are going to keep a low chance for some snow in the forecast for Wednesday. In the meantime, we’ll keep a close eye on the projected path of the storm and let you know if there are any changes.
Whatever happens with the mid week storm, it will be heading out into the Atlantic Ocean on Friday and our weather will improve just in time for the weekend. High pressure will build into the Northeast by Saturday. This is shaping up to be the sunniest day we’ve seen in quite a while as a dry air mass moves into the region. There is even a good chance our temperatures will end up above normal.
