The editorial The Week Ahead is used to describe the development of the
weather in the medium term. Its different to the daily forecast we issue
in that is gives an overall guidance, rather than a detailed day to day
prognosis. Depending on the prevailing meteorological conditions, the
accuracy of the forecast reduces significantly by the 4th or 5th day,
although it is still useful.
The Week Ahead is the result of thorough analysis of different forecast
models by our experts. The main focus is to find consistencies in
different models that by experience result in specific patterns. On the
other hand caution is used if the models significantly differ from each
other.
The right column displays the degree of certainty in the forecast trend
for each day.
"Certain" means that an event is likely to occur, whereas
"uncertain"
displays a questionable prognosis caused by different conclusions in
different models or by huge differences in the same model in back to
back test runs, therefore the forecaster has less confidence in this
forecast.
The temperature values are maxima values. The colors green, red and
blue display areas of different temperatures.
The text reveals the generally expected atmospheric conditions for the time period.
