@Thinksnow18 Talking to your favorite guy on facebook today. From Don Paul.
A few of his thoughts
"IMO, overdone. Sleet should dominate over freezing rain in most of WNY during transition to all snow after midnight, from NW to SE. I don't think the subfreezing layer gets shallow enough for prolonged freezing rain on the Niagara Frontier...maybe a few hours, but I think the GFS is somewhat too lengthy with the ZR. Very tight gradient between mod-hvy snow accum in northern Niag County and lighter amts to the S & SE. Poor model agreement at this time."
HOWEVER ( with my tail between my legs), several 18z hi res models now move the front thru Buf a little faster and, with warm air aloft, now favor a somewhat lengthier period of sleet & frz rain ahead of snow. Not as much as that GFS run, but potentially significant in the evening.
