Lots of new stuff to consume time here!
https://apps.ecmwf.int/webapps/opencharts 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. -- Norman Lynagh Tideswell, Derbyshire 303m a.s.l. https://peakdistrictweather.org twitter: @TideswellWeathr |

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. Graham Penzance |

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 -- Global sea level rise to 2100 from curve-fitted existing altimetry data http://diverse.4mg.com/slr.htm |

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 -- Norman Lynagh Tideswell, Derbyshire 303m a.s.l. https://peakdistrictweather.org twitter: @TideswellWeathr |

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. -- Global sea level rise to 2100 from curve-fitted existing altimetry data http://diverse.4mg.com/slr.htm |

Yes there is - that's how model output statistics are enhanced by MeteoGroup and probably many other forecasting centres worldwide (by obs, sat and radar imagery). It won't keep pace with rapid changes though, or all showers, obviously. Julian |

The MetO showing heavy rain for Penzance around noon. The BBC one not, just a shower risk, having picked up on the fact that the front is likely to be very weak as it crosses west Cornwall.
