A clipper system (low pressure that dives south from Canada) is forecast to come through the region this weekend, spreading light snow around Louisville. It looks like there will be some accumulations, just enough to whiten the ground by the latest estimates. I'm not terribly sure of the exact amount of snow we'll receive because this system has been bouncing around on the computer models. The main idea is that snow showers will start on Friday night and continue through Saturday.
You may have seen my various hints on Twitter and Facebook about some sort of snowstorm developing next week just in time for Christmas. The GFS long-range model had been advertising a potentially potent storm on December 24th for us, but that has since disappeared in the last few runs of the model (which could be due to the fact that the GFS model had some technical upgrades implemented today). Fear not! That storm has been replaced by several rounds of light snow between the 22nd and the 25th, meaning we still have a chance for a white Christmas if this happens. We're still 10 days away, so the forecast models will be very erratic and our big storm may even come back. On the flip side, there's a good chance that the snow could disappear completely and we'd be left with a cold, dry Christmas. Either way it'll most likely be cold enough to snow. Don't get too excited yet because this is a tricky forecast, but keep in mind that we could be dealing with some snow on or around Christmas.
