The good, the bad and the ugly... The good news is that we freshened up that snow pack out there. The fluffy snow will be great for any outdoor activities that you have planned this week that involves snow f- skiing, snowmobiling, sledding, snow angels, etc. (let me know if you have any other activities that begin with the letter "S") - get out there and enjoy it before it's gone, we all know the weather can change rapidly around here. The bad news is that our commute will likely be slow and white-knuckleish for one more day. The afternoon drive will be much better than the slippery drive in to work or school. Hang in there, it'll be much better tomorrow. The ugly side to most every winter storm is the bitter blast after the fact, that too will come to reality, but we're not expecting readings like what we had back in early January - WHEW! It'll be cold, but not terribly cold. Attention getting? Yes. By Wednesday and Thursday morning, you'll have no doubt that it's still winter. Here, take a look at the statewide low temperatures over the next couple of days - BRR!

Fresh Snow Aids Cooling Conditions
Take a look a the images below, they explain why it tends to be so much colder after a newly laid snow pack. Not only is it just plain old cold, but "Albedo" has a big impact the surface temperatures by reflecting sunlight back to space. Fresh snow is one of the highest natural reflecting surfaces causing temperatures to much colder than they otherwise would be.
You may have to study this graphic a little to understand it:
Here's a table that might help out:
Here's proof of the fresh snow - take a look at SOME of the snowfall reports across the state, which are still coming in:
