A quiet Christmas Eve day is with us, but there will be a 1 to 3" snowfall tonight developing this evening after 6 or 7 o'clock. This snow will be compliments of a little area of low pressure passing by to the south combined with an upper air disturbance. Roads will likely become somewhat slick & snow covered later this evening into the start of our Christmas Day, which yes will ensure us all of getting that white Christmas!
Christmas afternoon through much of Wednesday will be quiet, but then a major developing storm to the south will quite possibly deliver the "main course" of snow to the area late Wednesday right through Thursday. Current data is suggesting that the main storm will slide up just west of the Appalachians before it transfers it's energy just to the east of the Appalachians Wednesday night into Thursday, as the newly developing storm b/w Philly & NYC becomes the parent storm. The combination of significant synoptic snow, cold northeast winds developing late Wednesday night into Thursday will likely enhance the snowfall & provide some lake effect on top of the storm snow. At this time, we do not want to throw out snowfall numbers, but this could be one of the bigger snow events we've seen in a long while in WNY. This of course could still change, as the storm is still more than two days away, but this is one we will be watching very closely & have the latest on later today right through midweek. Stay tuned everyone, & have a great Christmas & holiday!!
