Lake Snow Warning for S. Erie, Wyoming, Chautauqua and Cattaraugus counties. Coldest air of the El Niño-dominated season. Band began impacting region late yesterday on a W-SW flow that veered W-NW which is the best trajectory for giving us the best snow. Snow forecast to continue here for the better part of the day albeit in a .5-1"/hour rate. Could end up with a foot or more before all is said and done. Warmer temps in the 50s later next week. |

A heavy mix occurred late yesterday afternoon into mid-evening along with winds gusting to 60 mph. No significant impacts on roads or issues related to power outages. Heavy snow in northern IA, WI as the strong pressure system ejected out of the panhandle toward Madison. This is a classic setup for heavy snow in northeastern IA (where I'm from). |

Lake Snow Warning extended for Chautauqua and Cattaraugus counties until 1 pm today. A constant W-NW (280-300) wind has put the bands in a near bullseye across the Southern Tier all of yesterday and throughout the night - a perfect setup for giving us maximum accumulation. Average sniwfall rate was 0.5"/ hour with occasional 1-2" rates yesterday afternoon. In the 9 years I've lived here this is probably the 3 highest LE total -- 16" |

Near record breaking lows predicted in the next few days as a series of systems continue pulling cold air from Canada into the NE US. |
