First off, I want to say that there are a lot of moving parts with this system and I will continue to up date the blog twice a day until it passes to keep everyone posted.
So the newest information has the storm system coming a little earlier compared to yesterday's models. The rain/snow mix could move into the Miami Valley before or around Noon on Friday depending on where you live. With the rain/snow mix it will cut back on our expected snowfall totals. Once the evening comes Friday we will cool off to turn to complete snow. It is still hard to pinpoint as to how far the rain/snow line will progress northward right now, because the difference in just a degree or two will mean the difference between rain and snow. I think the Miami Valley could see about 4-6." Now with that said.... if we get enough evaporative cooling, we could see the rain/snow turn to snow a little sooner and bump up our totals. Evaporative cooling is when precipitation falls through the air, it actually evaporates a little if the humidity is less than 100% and actually causes the atmosphere to cool down slightly... On the flip side, if we warm up a little more we could see our snowfall totals be dropped a bit.
I will update this again this evening when new data is in to help refine the forecast... until then, have a good one!!
Best,
Andrew Buck Michael
