This site is one of several but all of them have the same problems:
So I think all these sites lift the charts from each other.
But is there a primary source which is free?
Currently the only one I know is Avbrief but you have to pay for that, and while it used to be a very useful site I don’t use it for anything else nowadays. They carry the SigWx charts too but they are almost useless for light non-deiced non-radar GA.
Thank you, but I can’t find the UKMO MSLP charts there.
Maybe I should move on and use some of the other ones
I have been using this link for years without any problem:
That one, Josh, seems to be exactly the source for the charts in my first link. It even includes the bogus one at the end, which presumably the sites which grab the charts need to strip off
Look in the top left corner, click on fax
Yes – those are the same charts as on MWIS and every other site I know about.
Am I missing something?
The “06/12/18” link shows only one chart, and currently it is showing the 0600 for today, 9 hours too late.
It seems that the 0600 1200 1800 charts for a given day are elusive. Avbrief shows them
I wonder where they come from. Notice the first two have the same name – PPVA89.
Well, I think they come from Bracknell, at the UK met office. Probably a silly question, but have you looked there?
Back again. Yes, looks like that is the fountainhead but I can’t be sure as, would you believe it, they are on the subscription part of the service. This, for the most basic of all tools. Grrr.
Sembach have something similar, in colour, for free,
Sembach shut down last year.
There certainly are pressure charts, loads of them, mostly produced from the US GFS model, but all the free ones I know about don’t show fronts. AFAIK fronts are hand-drawn by a forecaster.
What I find bizzare is that the UK Met Office MSLP charts are all over the internet, free, but often an extra day old, and the current day’s or the next day’s 0600 1200 1800 are usually missing.
