This GEFS graph is showing we are in for an unsettled period of weather over the next two weeks.
The GEFS graph shows temperatures at 5,000 feet and rainfall. The top part of the graph is the air temperature at 5,000 feet and bottom of the graph is rainfall.
So looking at the graph it shows a rise in temperature during Wednesday and then it levels out until the weekend when the temperature will rise again. You can see a lot of scattered lines from the 13th so this tells me there is uncertainty in what the temperature will be after this. I would think daytime temperature will be around 10-12 c. Then it looks like becoming cooler again from around the 17th.
If you look at the bottom of the graph that shows rainfall. So there are a lot of high spikes especially around the 9th, 12th and 21st, this will be when the heavier rainfall is. But you can see spikes on everyday, so these will be mainly falling has showers.
