Powerful synoptic system passed to our north and west. With cold air already in place, warm air advection ahead provided over-running moisture that gave us 4" before sufficient warming turned the precipitation to rain. This was short-lived however. Much colder air behind system provided a Lake Snow Warning for the S. Tier (except for Allegany County) where W..NW..then N winds may bring up to a foot of snow to the higher elevations. |

Low pressure brought heavy rain to area late in the day yesterday followed by a quick transition to snow on its back side. 3" overnight. The low will stall over Quebec and provide a long-lasting LE event for the area for several days. Erie is 96% open. In addition, W-NW winds will gust to 55 mph. All of the above has prompted the issuance of a Blizzard Warning for S. Erie, Wyoming, Chautauqua, Cattaraugus and Allegany counties until 4 pm tomorrow (Friday) Snowfall totals by late early Sunday are forecast to reach 1-2+ feet off Erie and up to 4 feet off Lake Ontario.I have been a weather spotter for the NWS since 1992 and I do not ever recall a blizzard warning ever being issued for our area so this quite the weather-related event for us. |

Winter Weather Advisory for Chautauqua and Cattaraugus counties from last night to noon today. After an uneventful month of non-winter, Mother Nature reminds us she will decide when to assume we'll some of the snow of the season. In reality, this is pretty typical for WNY. I've seen this much snow on Mother's Day. |
