When buffeted by 50+ mph winds, blizzard conditions can be expected in many areas, as highlighted by the brighter orange areas (blizzard warning) on the map below over portions of Utah, Nevada, Idaho and Colorado:
All of the above will be taking place compliments of the strong upper level storm system and surface cold front that we've been forecasting to bring much colder conditions to the Plains & Midwest by Thanksgiving Day. That forecast still appears to be on track, with the latest surface forecast map for Thursday shown below:
Showers & thunderstorms can be expected along and ahead of the front on Thanksgiving Day across portions of far South & Southeast Texas as well as the Southeast, mid-Atlantic and Northeast.
The above map is valid for 6pm CST (7pm EST) on Thanksgiving Day. If the above timing verifies, the weather should be at least somewhat cooperative (rain-wise) for the Macy's Thanksgiving Day parade in New York on Saturday morning. The afternoon, on the other hand, will be quite wet.
