USEFUL Weather Analysis / NWP / Forecasting / Training Websites (updated January 2017):

Most comprehensive freely available model website out there. A vast amount of GFS data as well as links to other major global and regional model fields and ensemble stuff. Easy to navigate too. (Other models include: Euro4, UKMO, ECM, CMC, Arome, Arpege)
One of the newest model viewers out there, but using new visualization tools and offers a wide range of NWP focusing on Europe.
Similar site to WeatherOnline, but has some different links to other products, such as analysis charts (click FAX on the left for MetOffice surface charts). Site also has historical charts as well as re-analysis data, which are useful for projects. - The data and forecasts used on this site come from the Norwegian Met Service’s HIRLAM model in the first two days, followed by the ECMWF to day 10. One of the few places you can get free ECMWF-based forecasts. - ECMWF’s website with access to SLP, 850mb winds and 500mb level info. - type=prec - Icelandic Met Service’s Atlantic/NW Europe forecast– this data comes from the ECMWF model, and has more information than the ECMWF’s site, as it covers precipitation and cloud cover.
In German, but gives a good array of models and charts from different groups, particularly good GFS Precip Type display/loop. Canadian CMC model display, with link to lots of other stuff via the Meteocentre webpage. good, alternative European regional model, particularly useful for forecasting cloud, (uses GFS as boundary conditions). Free sign-up for more info as well.
Specifically designed for severe weather/convective forecasts – has a European and US domain and a severe weather forecasting users guide – (which is a link to a pdf on the page)
I highly recommend the users guide if you are interested in severe weather.
GFS displayed in table format – interesting way to visualise a model. (click 16 day forecast for the full GFS model run)
WRF model data run over the UK Domain (I don’t know much about this model).
Similar to the link above, this is another WRF model run over the UK, also runs a WRF short range ensemble. and 
Operational WRF Model data for the UK and Europe. - High resolution mesoscale model run over the UK domain by researchers at Leeds University. - Italian regional model (10km) run for Europe uses ECMWF for boundary conditions. I haven’t seen it perform very well here as the UK lies on the edge of model domain.
Specifically for Tropical Weather but gives good view of Atlantic weather systems.


SATELLITE, RADAR AND WX ANALYSIS PAGES: Very good analysis site. It overlays different satellite products on top of the ECMWF analysis panels. (Click Europe in the bottom left)
Great for Satellite data around Europe – best Vis resolution of UK on the web - Uses images from Sat24, but has some better functionality.
Radar site – run by the same group as the sat site above
Radar site – 15minute radar overlaid on Google Earth maps.;sess=
Very good radar site 15 minute updates are free, (5 minute updates by subscription), and a good GFS and model view too. - current weather observations over the UK.
Site run by the Icelandic Met Service but displays the Met Office ATD lightning network across Europe (The most accurate lightning detection network in Europe).
A network of private lightning detection across Europe, more real-time than the link above.
Real-time sea-surface temperatures around NW Europe.


LINKS PAGES: Pages that link to all kinds of weather sites… - European convective / severe weather forecast and associated “forecast discussion” which can be great learning tools. UK convective and severe weather forecasts along with some other background on severe weather in the UK. - Great amateur weather site with observations (and long term archive) from north of Norwich. Good source of data for projects, etc. - A website that gives thunderstorm forecasts for the UK (run by me and mostly my colleague Dan Holley) My website…a work in progress, but you get live data from my weather station - Obviously the MetO has Obs, Radar and Satellite as well as lot of educational and technical information, but this link is for their forecast map data mixing their UKV through Global model guidance.  - One of the best weather reference website on the web. - Glossary of Meteorology from the AMS. - Good UK weather message board


USA SEVERE WEATHER WEBSITES: - The Storm Prediction Center … The top standard for severe weather forecasting. Lot of live links and educational links for severe thunderstorms and tornado forecasting. The National Hurricane Center … all there is to know about tropical weather (Hurricanes, etc) forecasting.


TRAINING: - Best meteorology training on the web. This site is run by UCAR/NCAR in the US, and is used as a training facility by US National Weather Service meteorologists for personal development. Tutorials on all kinds of different weather types and events and you can save and print off certificates saying you have completed the course (these are recognised by most Met organisations and would look good in an interview / on a CV).
