First snow of the season. After temps in the 60s on Friday, a strong cold front and low pressure system moving east across Ontario brought a 2-3 hour period of rain, mixed prep and then snow Saturday. As cold air poured in behind the system, the lake effect machine kicked in late yesterday on strong NW winds. A Lake Snow Warning is in effect from yesterday afternoon through Monday am for Chaut, Catt and S Erie counties. Because the ground is so warm little snow is sticking to roadways. Hunters will appreciate the snow as this weekend marked the opening of the firearms deer season. Was fortunate to tag my buck at 8:30 am yesterday before the stormy weather moved in. |

Lake Snow Warning issued through tomorrow afternoon for Chautauqua and Cattaraugus counties. As winds veered from SW to NW S. Erie and Wyoming counties included yesterday and possibly part of tomorrow as winds veer back to the W-SW. First real LE event for the year. Erie at 50F which is 5 degrees above the mean. NW to W flow to continue for the remainder of today and tonight (possible L. Huron connection today). Storm totals predicted in 1-2' range. |

Lake snow warning continues thru 9 pm for Chautauqua, Cattaraugus and S. Erie (added early this am as band shifts north). A persistent W-NW flow brought periods of heavy snow yesterday and last night. Even tapped into a L. Huron for part of yesterday providing 2-3"/hour rates. Band will continue its slow northward migration throughout the day so I believe we have seen our heaviest snow here for this particular event. A synoptic system will move in tomorrow and Monday providing a few additional inches of snow before transitioning to just plain rain at its end. A bitterly cold outbreak will follow afterwards with perhaps some additional LE here.
LE storm total as of this entry: 15". (It is interesting to note that this is one of the highest snowfalls due to LE that we have received in the 10 years since I have lived in Randolph. The highest 4-5 day total was in 2010 when we received 60" and actually would be in my "top 10" since becoming a snow spotter in 1992.) |

Lake Snow Warning for Western Southern Tier from 7 pm yesterday until 7 am tomorrow. Band formed late afternoon yesterday in northern suburbs of Buffalo and shifted southward during the late afternoon hours yesterday and settled in our area overnight. Snowed hard all night. Bitterly cold arctic air making a brutal albeit temporary invasion into the northeast US. This on top of the wallop we received earlier in the week is making for a significant snow pack in th area. Unless we can break in the pattern this does not bode well for wildlife like deer that are beginning to be more brazen in their daylight visits in search of food. Was deer hunting in 3' of snow with snowshoes 2 days ago near Randolph and found the going slow and tough. |

Lake Snow Warning for Chaut, Catt, S. Erie and Wyoming counties from 4 pm yesterday until 10 pm today. A W-NW trajectory is bringing heavy snow (1-2"/hour). It was a very slow 30 mph drive home at 11 pm last night from Jamestown to Randolph with visibilities less than 100' on I-86. We had lost most of our previous deep snow cover due to warm temps and rain earlier in th week and this looks to repeat itself again early next week. |

Lake effect shifted south into the Western Southern Tier on NW winds yesterday. A connection with Lake Huron brought several episodes of very heavy snow with visibilities < 100 m in the afternoon. Was surprised more snow did not accumulate given the duration and intensity but likely was due to the very cold temps (10-14 degrees F). |

Late winter synoptic snow. Low pressure from Upper Great Plains system moving into western PA will transfer will weaken as a Nor'easter moves north along the coast and bombs. Persistent snow forecast thru tomorrow. LE snow off Erie and Ontario will add to totals as system pulls off Maine coast and we get N and then NW winds. |
