Not only does confidence continue to increase for a White Christmas, but my confidence is also increasing for many areas to pick up several inches of snow. For that reason, we now shift into Winter Storm THREAT mode from Wednesday night- Christmas Day.<\/p>\n<p>For those new to what a THREAT is, it simply means the potential is there for 4&#8243;+ or more of snow to fall in some areas. If confidence continues to increase, we will upgrade to an ALERT. If confidence decreases, we will enjoy whatever snow falls, regardless.<\/p>\n<p>This is a two-pronged snow system across our region. The first arrives behind the arctic front as cold air crashes in and low pressure develops along the front in the Appalachian Mountains. This is the setup I outlined days ago&#8230;<\/p>\n<p><a href=\"https:\/\/kyweathercenter.com\/wp-content\/uploads\/2020\/12\/SPECIAL-MAP-3.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-45983\" src=\"https:\/\/kyweathercenter.com\/wp-content\/uploads\/2020\/12\/SPECIAL-MAP-3.png\" alt=\"\" width=\"978\" height=\"584\" srcset=\"https:\/\/kyweathercenter.com\/wp-content\/uploads\/2020\/12\/SPECIAL-MAP-3.png 978w, https:\/\/kyweathercenter.com\/wp-content\/uploads\/2020\/12\/SPECIAL-MAP-3-300x179.png 300w, https:\/\/kyweathercenter.com\/wp-content\/uploads\/2020\/12\/SPECIAL-MAP-3-768x459.png 768w, https:\/\/kyweathercenter.com\/wp-content\/uploads\/2020\/12\/SPECIAL-MAP-3-440x264.png 440w\" sizes=\"(max-width: 978px) 100vw, 978px\" \/><\/a><\/p>\n<p>That will provide several hours of heavy snow in a band that increases in coverage and intensity the farther east it gets.<\/p>\n<p>By Christmas Eve and Day, the upper level low is likely to provide much of the state with some high ratio snows and even some snow squalls. Those high ratio events are often underplayed by the models, so the fact the models are seeing this suggests this part of the system could ramp up even more.<\/p>\n<p>Here&#8217;s my early look at who has the best chance for 4&#8243;+ of snow through Christmas Day&#8230;<\/p>\n<p><a href=\"https:\/\/kyweathercenter.com\/wp-content\/uploads\/2020\/12\/Snow-Map-1.png\"><img loading=\"lazy\"

4&#8243; or more inches of snow.\u00a0The westward trend continues to be evident on the models, so that may go a bit west in time.<\/p>\n<p>The WPC has a slight to moderate risk for 4&#8243;+ of snow across the eastern half of the state&#8230;<\/p>\n<p><a href=\"https:\/\/kyweathercenter.com\/wp-content\/uploads\/2020\/12\/WPC-1.png\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter
