Listen very carefully, ah will say ziss only wurnce.
Ian, this is the way I go about it. It differs from Ben's way so bear in mind I already have 'Use Real Weather Data' selected by default, as below.
So, I start Sim Launcher, and ensure User Defined Weather is selected. Then I either choose the default flight or create a new one at any other airport I fancy.
Once I am in P3D ( windowed mode...I always fly in windowed mode ). I click on the REX icon, allow the Weather Download Process to complete ( blue arrow ) then click on Fly Now ( red arrow ) as below...
You will then go back into the sim, and click on the Load Weather button ( yellow arrow ) as below...
In the sim, you will get a green message bar saying 'Assembling real time weather data' ( brown arrow ) as below...
...and at the same time, in REX, you will have this, as below. The green bar across the top ( orange arrow ) is the weather
download progress bar , not the weather insertion. Its just downloading weather data here, ready to inject into the sim. Note that this is different from Ben's method in that because I already had P3D running
before starting REX, REX knows where I am in the sim and I don't have to enter an ICAO code - as you can see on the little map, REX shows me correctly at Ketchikan. The disadvantage of this method, is that you don't get a met report as you do with Bens method
Once the weather is injected into the sim, you will get another green message bar saying 'Real time weather loaded successfully' and you should actually see some changes take place in the clouds etc as below
If you want to be sure and force a weather reload, right click on the black border and select Load Weather ( green arrows ) as below...You'll get the two green message bars come up again in the sim, as before
