Weather Forecast for Next 16 Days for PA278BZ

The confidence bar shows how likely the forecast is to be correct based on ensemble output. 100% confidence (or 4 bars) means that there is good ensemble agreement for the forecasted temperature and rainfall. Less bars means that the forecast is likely to change in the next model run.

The RainRisk and SnowRisk columns show the ensemble risk for rain within this period. This can sometimes be different to the actual forecast which may appear confusing. In general, this risk tends to be lower the further out the forecast is as some ensembles may predict rain, whilst the number tends to be higher and correlate better with the forecast rainfall amount closer to the current time.
