Here's the latest forecast on the upcoming snow storm for Western New York. New data continues to track low pressure in a good position for all snow for most of our viewing area. Snow will break out across the region Wednesday morning. Snow will fall heavy at times from late morning through the early evening. During the time, snow fall rates of over 1" each hour are possible. Strong NE winds between 20-30 mph will begin to reduce visibility as blowing and drifting of snow picks up. The low is expected to move across Eastern PA in the early evening hours.
Arctic air will pour Southward Wednesday night and Thursday. Leftover moisture and cold air advection will result in a few more inches of lake enhanced snow near and North of the thruway into the early hours on Thursday. It is for this reason that my forecast map has that area in the over 10" accumulation. Some areas North may end up with 15" if enhancement does what it does historically with lows tracking similarly. I do still believe that a mix will occur near the PA border for the first half of the storm thus lower snow amounts there.
Thanks for your patience, just wanted to see the latest data to be prudent. Enjoy the upcoming storm and we will have an update with John in the morning.
