Weathering the Weather: Pre-Turkey Snow?

It’s that time of year again. Time to start talking snow. This Wednesday, a significant snowstorm looks to affect the county with significant effects on travel on the busy day before Thanksgiving.

At this long lead, I think most of the county should get between 4 and 8 inches of snow. Far north MoCo may get a little more and far south MoCo may get a little less.

The storm will likely begin as light rain or non-sticking snow Wednesday morning, but temperatures will drop and it should start sticking by the early afternoon. Snow may fall heavily for a time Wednesday afternoon. It should taper off by the late evening.

Caveats: There is not much room for error in this setup. Temperatures will be right around freezing, and my accumulation map assumes heavy precipitation. If temperatures are just a couple degrees warmer, then accumulation will be much, much less. If they are a few degrees colder than we could see more. I’ll refine my forecast further and give a final update on Tuesday, when details such as this will be more clear.

Because ‘stickage’ won’t happen until the early afternoon we may have a normal half-day of school Wednesday. If it turns out the colder scenario is more likely, schools may close. At this point, I’d guess about a 50/50 chance of school closing Wednesday.

Feel free to ask any questions you may have in the comments below!
