Good Tuesday, everyone. We have a small break in the harsh cold and snow out there today, but our next system is set to roll in on Wednesday. Before then, temps make a run into the 40s today! Woot!
Another big temperature swing will lead to more winter weather rolling in here tomorrow. This is a setup that can throw down accumulating snow into much of the region, with additional snow makers lurking this weekend into next week.
The Wednesday system that has the chance to throw some decent winter precipitation accumulations on us after a period of rain. That rain breaks out along and ahead of a cold front moving in by Tuesday night and Wednesday. A major temp drop occurs just behind the front, with a lot of precipitation still falling. That results in a change from rain to sleet and freezing rain then snow.
The forecast models vary on how fast the cold catches the deepest moisture.
The European Model continues to show this well:
The GFS is similar:
The extreme models are the NAM and new version of the GFS. One has basically nothing, while the other continues to be on steroids:
Regardless of exact snow amounts, a quick drop in temps means icy roads will develop from Wednesday evening into early Thursday.
Another band of light snow or snow showers will arrive Thursday night along a weak arctic boundary. Another weak system may bring some light snow or flurries later Friday with another possible this weekend. The Canadian likes this one best:
The GFS and European Models are have that as more of a light snow event, with a bigger system following by later Monday and Tuesday:
That’s a lot of action over the next week and any one of those systems could amplify into something much deeper, but may not show up that way until a few days before.
Have a great day and take care.
