ECMWF has taken the first step in throwing its door open to all
interested parties. Full marks to them for doing this. UKMO
next? Perhaps not.

Thanks for the link Norman.

I looked at the MetO forecast for Penzance this morning, 2
raindrops & a black cloud at 10:00 & 11:00, then I looked at the
radar, a small shower just to the west, and well broken cloud
behind. Went out to Sennen & took Leanne for a walk the full
length of the beach in Autumn sunshine, not a drop. Well,
actually we walked the beach twice as she'd dropped her camera.
My still mending leg found the 2nd trip in soft sand a bit of a
struggle.

I find the models these days are often superb at predicted a
developing synoptic situation, but weather forecasts for the next
few hours are often worse than useless, which is the bit people
normally need. Surely there must be an automated way of feeding
reality back into the forecast to make it more reasonable. (I've
said that before & received all sorts of excuses, along the lines
of we don't work that way.)

All went downhill this afternoon.

The high-res radar imagery is by far the best short-range
forecasting tool.


Has anyone worked out how to toggle between 2m temp and 10m wind on
https://apps.ecmwf.int/webapps/opencharts/products/medium-2t-wind
I've tried 2 different browsers on win7 and win10
Calling up the legend shows a colour bar from -48 to 52,
presumably the temp scale.
Under that, text saying 10m wind (m/s), main pane is a graphic that
probably shows wind "colours" and wind arrows but no relevant scale
that I can find

Don't think you can do that. The colours on the chart are the 2m temp.
Black arrows show the 10m wind direction. I assume that the speed is
proportional to the arrow length but there is no actual scale. I
suspect there is supposed to be one but it's not there yet.

One useful feture that I found out by accident is that if you click on
any point on the map you get a 10-day meteogram for that point,
including 2m temp and 10m wind speed


At least its not just me. It took a while for me to realise there was a
button to call up the scale.
I'll have to stay with GFS, with colour scale for wind strength, to pick
off sampling to infer winstress and then surge in the Eng Channel.
