First Defense: Lake Effect Snow Continues Through This Evening



JAMESTOWN – The National Weather Service maintains the Winter Weather Advisory until 6 PM tonight for the Southern Tier.

Lake effect snow has setup off the eastern end of Lake Erie on the back edge of a weak clipper system that has passed through the region.

Our exclusive “Snow Machine” algorithm in our high resolution in-house computer model has been showing additional accumulations of 1 to 2.5 inches, with the possibility of 3 more additional inches on the hills, especially on the Chautauqua Ridge.

This will, no doubt, seal the deal for a White Christmas for the Southern Tier; the term “White Christmas” is having at least one inch of measurable snow on the ground on Christmas morning as defined by NOAA.

Snow showers will continue in light form for Christmas Day with near-average temperatures hovering in the lower 30s (upper 20s across the valley locations).

Expect more clouds than sun near the Lake Erie shore with near overcast skies further inland.



Another warmup comes our way towards the end of the week; we’ll be flirting with 50 come Friday with widespread rain showers.

Snow melt will, once again, be likely during this timeframe before another system rolls through over the weekend, dropping temps back into 30s with some snow showers.
