Thanks all for the inputs. I started importing going backwards from most recent, ie December, then November. I have WC data for January. I read through all the posts regarding importing, and downloaded an excel spreadsheet that had been created to move WD data to WC. I modified this spreadsheet for my Weather Underground data, and put it in the proper text file format for WC in the Data folder. I can query the month of November data, I can see it by day, it shows up in the records tool, so I know it is formated properly and WC is reading it. December which I imported, shows up in the Year over Year, but not November. I read somewhere that WC will only load the last 2 months of data unless it needs the data. I am wondering if the Year over Year page will not display data that is older than 2 months old that has been imported and not created by WC.
