Good Tuesday morning!

Our early start to Winter continues Tuesday with lake-enhanced and upslope mountain showers. It's also chilly and blustery thanks to persistent northwest flow.

There is not a storm system or significant area of low pressure to blame for a handful of passing showers Tuesday. Instead, our chance for rain and snow is terrain-driven via Lake Champlain and our mountain ranges.

First, the mountains: Increasing moisture and overall cyclonic flow will combine with vertical lift off the Adirondacks and Green Mountains to provide scattered snow showers Tuesday, especially during the afternoon and evening. While I wouldn't rule out a few flakes in valley spots, accumulating snow is confined to the foothills, mountains and Northeast Kingdom again today. A dusting to 2-3" is expected, mainly above 1500'.

Now, the lake: Cold, northwest wind will sweep across the still fairly warm waters of Lake Champlain (water temp, low 50s) and spark showers in the Champlain Valley. While mainly spotty rain is expected, there may be a few snowflakes or even some graupel! Graupel are those little white snow pellets, formed by liquid that supercools around snowflakes; not the same thing as sleet or hail. 

Whether you see some showers or not - and some won't - it's a cloudy and chilly day. Temps top out in the low to mid 40s with a brisk northwest wind of 5-15 mph. Wind chills will likely be stuck in the 30s today. Across southern Vermont and southern New Hampshire, instead of mostly cloudy skies, look for partial sunshine.

Tonight, any lingering showers come to a close with drier air taking over briefly for Wednesday.  After dipping into the upper 20s to near 30 degrees overnight, temps hover in the 30s to near 40 degrees tomorrow under a mix of sun and clouds.

Thursday into Friday, our active weather pattern picks right back up again with a strong area of low pressure bringing gusty winds, areas of rain and several more inches of heavy, wet snow for the mountains. This go around, we may even see some freezing rain in the Green Mountains or eastern Vermont, potentially creating some issues on the roads early Friday morning. As the end of the work week approaches, the details of the forecast and any potential impacts will become clearer. Stay tuned!

Also, another early heads up, this time for the weekend. A second low pressure system will likely pass to our north on Saturday. This would put our region in the 'warm sector' meaning mostly rain showers.

Have a fantastic day!
