We've seen a taste of fall weather so far, but next week we could see our first real taste of winter weather.
First off, the first graphic to the right shows sub zero temperatures gathering in Alaska with single digits in western Canada where a strong arctic high resides.
The two longer range models used for the seven day forecast (the American GFS and the European ECMWF) both show the arctic high dropping into the United States next week bringing very cold air for early November.
Next Tuesday, we could see temperatures falling from early morning 50s through the 40s during the day, to low to mid 20s by Wednesday morning.
Wednesday's highs may never get out of the 30s. Wednesday night into Thursday morning could be the coldest temperatures yet with teens to low 20s for lows.
News 2 meteorologist Davis Nolan can't rule out the upcoming cold air squeezing out some snow showers Tuesday night, as well! Some models indicate a possible low in the southeast that could bring east Tennessee a big snow.
The snow part is not a lock, but when the models agree on an arctic high dropping in from Canada (where there is good Canadian and U.S. data inputted), you can usually count on the cold air.
