This chart shows the 14 day weather trend for Covilha (Castelo Branco District, Portugal) with daily weather symbols, minimum and maximum temperatures, precipitation amount and probability.

  • The deviance is coloured within the temperature graph. The stronger the ups and downs, the more uncertain the forecast will be. The thick line represents the most probable trend.
  • Variation in precipitation is represented as a „T“. These uncertainties usually increase with the number of forecasts days ahead.
  • The forecast is created with „ensemble“ models. Several model runs with varying start parameter are calculated to estimate the predictability of the forecast more precisely.
