First Defense: Lake Effect Snow Continues For Some Through Early Saturday

JAMESTOWN – As we talked about, lake effect snow has set up shop off of Lake Erie last night and has been impacting parts of the region throughout the morning today.

High temperatures occurred early today. Since the morning hours, temps have been on the decline through the 20s. We will end the day in the lower teens for most areas and upper single digits for the hills and vallyes.

Winter Storm Warning for Lake Effect Snow remains in place for Chautauqua and Cattaraugus Counties until 7 a.m. Saturday morning. The most amount of the snow will come this afternoon.

The snow band will jog north and south so it won’t be able to deposit as much as it possibly could if it were staying over one area for long periods of time.

While the band will still be moving, we think it will mainly focus on the central‌ and northern parts the region; that is where we expect the highest overall amounts of accumulation will be. Some spots may get a sold foot by Saturday morning.

Once you work south towards the New York/Pennsylvania line, that is where the least amount of snow will be observed due to the band not moving that far down and a shorter duration. There, maybe 1 to 3 inches could be possible.

The Next Big Thing: We have been hinting at this for some now and confidence is increasing for another deep trough setting up late next week, bringing in some of the coldest weather we’ve seen this year.

The Arctic air we seen last weekend will feel like a heatwave compared to what we could be going through next week, if the models are correct on this.

Some of this “cryogenic” cold will echo the cold temps we seen with the “Polar Vortex” back in February 2014.

Highs by late week will struggle to reach the single digits with a very harsh wind chill factor likely as well.
