Cooler temperatures with rain and showers continue to end the month.

This GEFS graph is showing very cool temperatures with rain and showers.
The gefs graph shows the temperature at 1,500 metres and the bottom of the graph is the precipitation. The thick black is the average 30 year temperature. On the precipitation line, the higher the spikes the greater amount of rain we can expect. There are so many thin lines because each line is a members of the gefs. The closer the lines are the more confidence we have in the forecast.
So looking at the graph you can see a sharp drop in the air temperature only recovering to around average around the 29th continuing into early October. Looking at the precipitation you can see there will be some rain and showers around at some point everyday.
