Can i suggest using Domoticz internal Weatherunderground and patch your script to use that.. and remove all other weatherunderground from the script...
(I can not see why it is in the script anyway, since the hardware was already available, it kinda double if you have both this script & weatherunderground as hardware... but anyway..)...

os.execute(cmd)
local ogimet = io.open(tmpfile, "r")
local synop = ogimet:read('*all')

I do not know where os.tmpname stores its file, and if you have rights there (it should be, but who knows) so you can also hardcode the tempfile

You should remove the temp files with
if you are done with it, or else it will fill up your storage. and you should check your the temp folder printed with the debug, for the already existing temp files you created and delete those...

it probably wanted to write were it has no rights. Who knows... i should have opted for the hardcoded to begin with... anyway.
