Warm air appears to be winning out with this storm, as most reliable data continues to suggest more rain & mix than snow for most. Therefore above expected snowfall map looks like it does. Best chance to pick up a more significant wet snowfall would be the high terrain of Wyoming, Livingston & Ontario counties, i.e. Bristol Hills. If slightly colder air evolves as depicted on the Canadian & NOGAPS occurs then it would turn snowy later tonight into Wednesday, but this scenario does not look likely. The morning commute for many will likely be wet & possibly a little sloppy & slick, especially on secondary roads from the minimal snow & sleet occurring due to dynamic cooling.
As mentioned in my last blog, the air will grow colder for moving toward & into the weekend with blustery winds, some snow showers & limited lake snows expected through Saturday anyways. Minor accumulations are expected at this time for the end of the week into the start of the weekend, but that looks to be it. Highs will range from the mid 20s to low 30s for the weekend, but wind chills will likely be much lower than that thanks to a gusty northerly wind.
Have a good night WNY!
