We have an absolutely loaded weather pattern taking shape over the next few weeks and it all gets started on Wednesday. That&#8217;s when the first of 3 major systems impacts our region. After that, we will bookend our long Christmas weekend with impressive\u00a0systems. One is super wet and the other is\u00a0looking white.<\/p>\n<p>Before we get to the weekend setup, let&#8217;s talk about the first system rolling in late tonight and Wednesday. The models continue to waffle just a bit on how far north the rain gets, and the potential for a touch of snow or a mix for some.<\/p>\n<p>The NAM is super wet and very far north&#8230;<\/p>\n<p><a href=\"https:\/\/kyweathercenter.com\/?attachment_id=26793\" rel=\"attachment wp-att-26793\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-26793\" src=\"https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/NAM-3-2.png\" alt=\"\" width=\"1079\" height=\"676\" srcset=\"https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/NAM-3-2.png 1079w, https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/NAM-3-2-300x188.png 300w, https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/NAM-3-2-768x481.png 768w, https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/NAM-3-2-1024x642.png 1024w\" sizes=\"(max-width: 1079px) 100vw, 1079px\" \/><\/a><\/p>\n<p>With a stronger system, the NAM is able to create some colder air on the northern edge of that rain shield.

This front will have a strong wave of low pressure along it, bringing some wild weather into Friday night and early Saturday.

Heavy rain is likely along and ahead of the front, and I&#8217;m increasingly concerned about the flood potential to start the weekend.<\/p>\n<p>The GFS rainfall map for this first system is likely too far south and east with the heaviest totals&#8230;<\/p>\n<p><a href=\"https:\/\/kyweathercenter.com\/?attachment_id=26798\" rel=\"attachment wp-att-26798\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-26798\" src=\"https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/GFS-Rain-4.png\" alt=\"\" width=\"1072\" height=\"674\" srcset=\"https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/GFS-Rain-4.png 1072w, https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/GFS-Rain-4-300x189.png 300w, https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/GFS-Rain-4-768x483.png 768w, https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/GFS-Rain-4-1024x644.png 1024w\" sizes=\"(max-width: 1072px) 100vw, 1072px\" \/><\/a><\/p>\n<p>The Canadian Model is farther west&#8230;<\/p>\n<p><a href=\"https:\/\/kyweathercenter.com\/?attachment_id=26802\" rel=\"attachment wp-att-26802\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-26802\" src=\"https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/Canadian-11.png\" alt=\"\" width=\"1077\" height=\"794\" srcset=\"https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/Canadian-11.png 1077w, https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/Canadian-11-300x221.png 300w, https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/Canadian-11-768x566.png 768w, https:\/\/kyweathercenter.com\/wp-content\/uploads\/2017\/12\/Canadian-11-1024x755.png 1024w\" sizes=\"(max-width: 1077px) 100vw, 1077px\" \/><\/a><\/p>\n<p>The European Model is also farther west.
