Eax on next week: best chance (20 to 30 percent) for precipitation during this forecast resides in the Wednesday into Thanksgiving Day timeframe. However, mid range models have not had very good run to run consistency and still have not come into agreement into how to handle an approaching upper level trough. The 21/00Z GFS is much more progressive with a upper level trough moving through the northern Plains into the Upper Midwest Wednesday into Wednesday night keeping the precipitation chance shunted to the south. The 21/00Z EC is advertising a much deeper upper level trough that would dig through the central Rockies and into the central Plains Wednesday into Thursday before moving through the area Thursday night. This solution would produce a rain to snow scenario with accumulating snow possible Thanksgiving Day into Thanksgiving night. This system will certainly need to be monitored as it may produce hazardous driving conditions on one of the biggest travel days of the year.

From EAX: Kansas City has not been in the 20s since 3/27 when the low was 21 degrees. That is a string of 238 days with temperatures 30 degrees or above which is the 9th longest on Kansas City's 137-year period of record. That streak may end tomorrow morning (the forecast low is 30)...if not, it will most likely end Friday morning (forecast low 26).

End of the GFS is nice and cold.

Coldest airmass for NA that has been modeled so far this winter.

Cold airmass after cold airmass into the middle of the country, with the PNW getting clipped by some very cold air in early December.
