Based on this autumn's/winter's weather and on a little research, I think these maps should be closer to the average dates for these locations.

Dear Don, the locations are very close to each other.
Usually season borders float from year to year.
Are you sure we need to create 2 season maps for locations that are close so much?

Season-maps is a very rough technique, we need precision on a week level.

Hi Pavel,

It is the mountains that make the difference. Reno and Carson City are in the rain shadow while Truckee and South Lake Tahoe are near the summit. It's dramatic how suddenly the landscape changes from forest to desert when you travel from Truckee to Reno.

That being said, if they must share a season map then I think this would make a good compromise:

Truckee, California/USA Latitude: 39.33 Longitude: -120.18
South Lake Tahoe, California/USA Latitude: 38.93 Longitude: -119.98
Reno, Nevada/USA Latitude: 39.53 Longitude: -119.81
Carson City, Nevada/USA Latitude: 39.16 Longitude: -119.77

03.01:spring/05.01:summer/09.30:autumn/11.25:naked/12.10:winter

Thank you Don!
In a case you will not be happy with the compromise, please le me know we will try to make the season-maps more complex.
The season-map will be updated within a couple of days.

Your welcome and thank you.
