A little light snow this weekend

Good Saturday, everyone. We’ve made it tot the weekend and Old Man Winter is throwing a couple rounds of light snow across parts of the region. This action is the warm up act to a rather harsh looking pattern for the week ahead.

Let’s begin with today and roll forward. An area or two of light snow and flurries will roll across the state, leading to some minor accumulations in a few areas. Outside of today’s flakes, skies may become partly sunny for a time.

Another light snow maker then shows up later this evening and takes us through early Sunday. This has a better chance to put down light accumulations.  I will have your tracking tools in a bit.

The arctic front arriving late Monday into Tuesday continues to be on course to bring snow and bitterly cold air our way. How much snow depends on a wave of low pressure developing along the front and slowing it down. That’s a very plausible scenario, especially with a storm ahead of it forming off the east coast. The stronger that storm, the slower the front in our region, allowing for a wave to develop along it.

The NAM only goes through Monday night, but is showing this scenario:

Notice the negative tilt on the trough for Monday night:

That’s the key to this whole thing, you want that trough to be leaning back as opposed to leaning forward. If that trough is positively tilted, you only get a band of snow right behind the front.

The European Model continues to like the wave idea the NAM is showing:

The Canadian is singing a similar tune. Also, watch the system developing behind that:

The GFS is always the most progressive of all the models and it’s no different this go around:

Bitterly cold temps crash in behind this system, with the absolute brutal stuff staying just north. If we can get a flatter looking polar vortex, it would allow west-east moving snow makers to cut underneath it across our region later next week.
