Living with Inversions

Duration of day: 6 hours, 32 minutes (6 minutes, 35 seconds shorter than yesterday)


I check the National Weather Service 7-day Forecast for the Tanana Valley nearly every day.  Today I read through this and didn't think too much about it - except for the temperature difference being very wide today.  Then I thought about those who do not live in regions where inversions are the norm for winter weather.  Following is today's forecast:


Rest Of Today: Partly cloudy with a few flurries. Highs zero to 10 above. Light winds.

Tonight: Mostly clear. Lows 20 to 25 below...except around zero on the hills. Light winds.


The city of Fairbanks and Community of North Pole are nestled near rivers, the lowest point in our area.  Since Fairbanks is ringed by hills in three directions, the cold air settles into the river valley while warmer air drifts up to the hills.  As the reading suggests, the temperature difference can be marked.  Another benefit of living higher is the smoke from wood stoves does not meet the inversion layer and hang under a noticeable ceiling as it does in the valleys and city.

Our house is not as high up the hill as those living behind Cold stream or the top of Skyline or Summit Drives, but we still experience as much as 10F degrees warmer temperatures than in town.
