Here's what we wrote about it on a recent Facebook post: The Flyable Conditions overlay uses a new short-term weather forecasting technology performing fusion of data streams from a number of near-realtime information sources, including satellite imagery (EUMETSAT), ground observations, and traditional numerical weather prediction forecasts. The data isn't currently available anywhere else. I understand that although there is a NWP model used, it doesn't play a big part in this forecast.

It is not applied on the level of specific met products, the correctional data in forecasting is built directly into the mathematical models - the quality of everything forecasting beyond 3 or 6 hours time frame was always established only by including actual data of a big number of forecast stations. I remember the times when shipping business stopped delivering met data (that was once a mandatory obligation for each and every ship on the oceans, to deliver met data once a day) 'because satellites will do that job now' = one of the bigger failures in science, that did hurt met forecasting models deeply. Current estimate of the scientific crowd is that it may take something like up to 2 years to get the mathematical models back to were they where before Covid-19 only due to the missing air data.

Please alert us again if you see the same thing, as we can hopefully then point our forecasters to the webcam and their data sooner. This is the way the algorithms get improved. Forecasts will get back to normal once air traffic significantly starts again. Weather forecasting currently still suffers badly from the missing weather data collected from airliners. Computer simulation of weather without current adjustment data is video gaming ... ;-).
