This GEFS graph is showing the temperature will start cooling early November.
This top of the graph shows the temperature at 5,000 feet. The bottom of the graph is rainfall.
So you can see a slight rise in temperatures over the coming days peaking right at the end of the month and the first day of November. Temperatures look like falling from around the 3rd becoming quite cool around the 5th.
There are lots of different spread lines, this means the members that make up the GEFS don’t have a lot of confidence in what the temperature will be. But we can take from this it will start to feel very cool around bonfire night.
There is little in the way of rainfall, any rain looks showery in nature.
