One of the coldest Thanksgiving holidays in recent memory. Temp range 18/01. During the morning hours, two separate lake-effect snowsqualls rolled through. During the first one, shortly after 0900, visibilities crashed to as low as a quarter mile. Dumped a quick .7" of fluff. Temps, at that point were at 15 F. Sun broke out through the shallow low level cloud deck. Then, after 11 am, a second squall came through. Another .3" fell, with visibilities down to a half mile. Filtered sun returned, but flurries persisted on and off till about 13:30. Remainder of afternoon featured scattered Sc clouds with light N-NW breeze. At sundown, 16:40, skies were clear. Rapid temperature drop in the evening and night hours, bottoming out shortly around or after midnight. Strong, cA High pressure system sailed right over western-central NY during this overnight time frame. Satellite imagery indicated a solid sheet of low level stratus/SCu clouds propagating eastbound from Ontario province, Lake Erie. By 08:30 the leading edge of that arrived here. At obs time, temp 18 and overcast (stratus deck). |
