Abstract: Medium range weather forecast and weather based agro advisories help in farming community by minimize the production losses due to unfavourable conditions. So, there is need to study reliability and suitability of the medium range weather forecasts for further improvement. In this study verification of medium range weather forecast of Malkangiri, Odisha during the period of 2017-18 are discussed in respect to rainfall and temperature. Usability based on quantity of rainfall was higher in winter season (100%) and very less in monsoon season (17.02%). Except monsoon season, the quantitative forecast of rainfall revealed higher reliability over percent forecast accuracy (ratio score). Higher Root Mean Square Error (RMSE) of rainfall in monsoon season (18.48) indicated lower accuracy in prediction. Annual usability of forecasted maximum temperature and minimum temperature were 71.11 and 76.19%, respectively. The highest percentage of usability for maximum and minimum temperature was observed in winter season. The RMSE for minimum temperature was found lower than maximum temperature indicating higher accuracy. Furthermore, there is scope of improvement in usability of rainfall mainly for monsoon season as well as temperature for more income of farming community of Malkangiri district of Odisha by following weather based agro advisories.
