Good Sunday evening. Heavy rains continue to pound much of the bluegrass state as a powerful cold front swings eastward. This front is causing temps to drop like a rock and that trend will continue across the central and east this evening and overnight. Some sleet and light snow have been reported west of Interstate 65 and some of that could work into the rest of the state overnight.
We will also need to keep an eye on the black ice possibility tonight. There is a ton of water out there and readings heading into the upper 20s means look out.
What happens after this? The cold front slows down just to our east and allows for two waves of low pressure to develop along it. The first wave comes later Monday into early Tuesday. The late afternoon model runs continue to trend a little stronger with this system and that means a better shot at some wintry weather. A mix of rain, snow and ice will be possible late Monday into Monday night.
The NAM shows a little bit of everything falling, but still tries to put down some light snow…
Again… the model is having a difficult time determining precipitation type. Let’s just call it a wintry mix at this point and figure it out later.
There could be similar system late Tuesday into Wednesday.
Several models have been showing a southern low developing toward the end of this week. The GFS Ensembles and the Canadian have been leading the charge on this. The new GFS is picking up on it…
We will need to keep an eye on that setup.
The massive dump of arctic air then dives in next weekend into the following week. There is no disagreement on the models with that aspect of it. Many of the models are also trending toward several snow systems to go along with the bitter cold…
Have a great evening and take care.
