if i do a "yesterday" query the meantempi does not match what the wunderground website shows as the avg temperature for yesterday.

what is the best way to get the AVG temp for "yesterday" for a zip? help! :) thx

maxtempi and mintempi don't match up either. this is for zip 91942.

wunderground human-readable page is:
http://www.wunderground.com/weatherst...

i'm using the summary data provided at the end of the detailed observations, the json literal being:

"fog":"0","rain":"0","snow":"0","snowfallm":"0.00", "snowfalli":"0.00","monthtodatesnowfallm":"", "monthtodatesnowfalli":"","since1julsnowfallm":"", "since1julsnowfalli":"","snowdepthm":"", "snowdepthi":"","hail":"0","thunder":"0","tornado":"0","meantempm":"22", "meantempi":"71","meandewptm":"11", "meandewpti":"52","meanpressurem":"1017", "meanpressurei":"30.03","meanwindspdm":"2", "meanwindspdi":"1","meanwdire":"","meanwdird":"280","meanvism":"17", "meanvisi":"11","humidity":"","maxtempm":"33", "maxtempi":"91","mintempm":"11", "mintempi":"51","maxhumidity":"100","minhumidity":"23","maxdewptm":"13", "maxdewpti":"55","mindewptm":"8", "mindewpti":"46","maxpressurem":"1018", "maxpressurei":"30.07","minpressurem":"1014", "minpressurei":"29.94","maxwspdm":"23", "maxwspdi":"14","minwspdm":"0", "minwspdi":"0","maxvism":"32", "maxvisi":"20","minvism":"11", "minvisi":"7","gdegreedays":"21","heatingdegreedays":"0","coolingdegreedays":"6","precipm":"0.00", "precipi":"0.00","precipsource":"","heatingdegreedaysnormal":"","monthtodateheatingdegreedays":"","monthtodateheatingdegreedaysnormal":"","since1sepheatingdegreedays":"","since1sepheatingdegreedaysnormal":"","since1julheatingdegreedays":"","since1julheatingdegreedaysnormal":"","coolingdegreedaysnormal":"","monthtodatecoolingdegreedays":"","monthtodatecoolingdegreedaysnormal":"","since1sepcoolingdegreedays":"","since1sepcoolingdegreedaysnormal":"","since1jancoolingdegreedays":"","since1jancoolingdegreedaysnormal":"" }

I see what's going on here. The "history" pulls from National Weather Service locations because those are official weather history locations. The station you're referncing on our site is a Personal Weather Station, and so the temps are different. The apples to apples comparison would be http://www.wunderground.com/history/a...
