Regine, I’m baffled too! I found no clues in the plugin code.
I found some names by typing in different values using http://icons-ak.wxug.com/i/c/g/ as a prefix (e.g., http://icons-ak.wxug.com/i/c/g/sunny.gif). Here are the ones that worked:
snow.gif
rain.gif
sunny.gif and clear.gif are the same icon
cloudy.gif
But in the examples at https://katz.co/wunderground/ there is one more that is similar to cloudy. I tried overcast, gray, partly-cloudy, with no luck. Will keep trying but in the meantime anyone with a clue is invited to jump in!
Thanks,
Donna
Thanks to @wdesousa for answering this question in a different thread (http://wordpress.org/support/topic/icons-ecast-hosed):
As to icon names – if you grab them from http://www.wunderground.com/weather/api/d/docs?d=resources/icon-sets they are already correctly named to correspond to the different weather events.
So here is the list I came up with:
Daytime
chanceflurries.gif
chancerain.gif
chancesleet.gif
chancesnow.gif
chancetstorms.gif
clear.gif
cloudy.gif
flurries.gif
fog.gif
hazy.gif
mostlycloudy.gif
mostlysunny.gif
partlycloudy.gif
partlysunny.gif
sleet.gif
rain.gif
sleet.gif
snow.gif
sunny.gif
tstorms.gif
cloudy.gif
partlycloudy.gif
Nighttime
nt_chanceflurries.gif
nt_chancerain.gif
nt_chancesleet.gif
nt_chancesnow.gif
nt_chancetstorms.gif
nt_clear.gif
nt_cloudy.gif
nt_flurries.gif
nt_fog.gif
nt_hazy.gif
nt_mostlycloudy.gif
nt_mostlysunny.gif
nt_partlycloudy.gif
nt_partlysunny.gif
nt_sleet.gif
nt_rain.gif
nt_sleet.gif
nt_snow.gif
nt_sunny.gif
nt_tstorms.gif
nt_cloudy.gif
nt_partlycloudy.gif
Thanks @mcdonna – that’s a good list. Version 2.x includes the icons in the plugin file, so you can refer to those in the /wunderground/assets/img/icons/ directory.
