12/21 - 4pm - No White Christmas, But an Icy Tuesday?

While we won't be lucky enough to experience a white Christmas, winter weather isn't taking a break. As our rain system for Christmas Eve enters the area on Tuesday, temperatures will be below freezing. This could cause some icing issues if it doesn't warm above freezing as fast as the models say it will. I think we'll definitely see a little bit of sleet and freezing rain on Tuesday afternoon with warm air entering the upper levels, but I'm not certain how long that will last. If we warm slowly at the surface on Tuesday, we're in for an icy mess. If we warm quickly throughout the afternoon, we'll switch to liquid rain before the evening with little or no problems around the area. We'll just have to wait and see how this system treats us on Tuesday. In any case, we should be completely switched over to liquid rain by late Tuesday and into Wednesday (Christmas Eve).

Also, today is the first day of Winter! With a temperature of 22 in the city and winds making it feel even colder, it's sure making its presence known. After checking the latest runs of the GFS and NAM models, we're set for what looks to be the coldest night in quite some time. I think the Louisville Metro will see a low of 8 tonight, but the suburbs could get a couple degrees lower. Regardless of air temperature, wind chills will assuredly be below zero, so bundle up! Expect a repeat of today's weather for tomorrow, with a little less wind.
