See this thread for how to filter out these ridiculous temps:

The important bit is this from Steve:
There's an undocumented facility that may help. Stop Cumulus and edit the cumulus.ini file. In the [Station] section add a line:
EWTempdiff=x.y
Where x.y is the maximum difference in degrees that you are prepared to accept between successive data readings.
Also, I have wrapped my housing in Al foil and put a white plastic juice container over that, open at top and bottom. It seems to largely eliminate direct solar heating of the housing, and cost nothing to do. My unit is in full sun all day and without that reads temps 10-20C higher than reality.
