Hi John,
With this icon set, you have the best set to manage cold season!
As you seen, icons are named with 3 different numbers:
1st digit use IsFreezing webtag, so, if temperature is below 0c/32f
winter icons will be displayed, but if the day become warmer, summer icons
will be displayed. So, in the same day, winter icons could be used in the night
then, summer icons will be used in the middle of the day and finally return
to winter icons at the end of the day... all automaticly!
(2nd number is for day/night and 3rd for the forecast itself!)
So, you're now ready for some cold days and have nothing to do
to switch to summer and winter icons set.
Regards,
Jacques
