ForecastWatch has always calculated the percentage of forecasts right on (no error), and within 3 degrees. Bins, or cohorts, have been added to cover the full range of temperature error and all historical data has been re-aggregated to calculate these data. Temperature error cohorts exist for -10 degrees or less, -9 to -7 degrees, -6 to -4 degrees, the existing -3 to +3 degrees and 0 degrees, +4 to +6 degrees, +7 to +9 degrees, and +10 degrees or more.
These cohorts are currently only available via the "Download" links on the Drilldown product. The download links are found directly under the "Days Out" and "Month" buttons. The "All Cities" link will download a file containing all 800+ tracked cities. When in a State or City view, an additional link appears, allowing download of just the cities in the currently viewed State.
The downloaded file is in CSV (comma separated value) format, which can be easily read by most spreadsheet programs, including Microsoft Excel. A future release of ForecastWatch will add these cohorts to the web display.
High and low temperature errors for July have been audited and loaded into the Drilldown and Compare products. The Year-To-Date numbers have also been updated. We also deployed additional auditing software that will allow us to zero in on even smaller data errors. We ran this tool against the full data set, which caught a few more actual temperature errors.
With the addition of July, ForecastWatch has surpassed FIVE MILLION scored forecasts!

In addition to additional cohorts, the August release of ForecastWatch provides several other enhancements. Intellicast is now queried differently, which brings the number of tracked cities on par with the other forecast providers. A bug was fixed which resulted in the 1 to 5 day cohorts (with 3 degrees and 0 degrees error) to use the 1 to 3 day cohorts to calculate percentage. And finally, the Compare maps now use forecasts from The Weather Underground (provided by the NWS) until the NWS fixes their problem with returning western region forecasts, or until ForecastWatch determines a better source for NWS forecasts.
