Algorithm for temperature variances needs to be tweaked.
It seems that your system likes to drop my PWS, KNJFRANK9, from the list of available PWS locations due to the reported temperature, though no error messages are generated.
Before anyone cries "Radiation" issues, I have another thermometer, from the same company on a shaded, unheated, north facing wall and they agree to within 1 degree F. The one one the wall does not report to WU, but I check it often enough just to compare readings.
So I cannot see how radiation issues can be the cause when one is in constant shade and the other is in open air in the manufacturer's designed housing and they are both reporting the same temperature.

For reference the next closest PWS to me is KNJPITTS1, which is located on Buck Rd., Pittsgrove, NJ
