My understanding is the pandemic actually caused some serious gaps in weather forecasts. Some commercial flights transmit weather conditions to central authorities , which are extremely useful for building granular forecasts. During the pandemic, commercial air traffic plummeted. While it has returned to normal levels, it seems the models are still missing some historical data.
Interesting. Not sure that is the issue here though. No other weather forecasting source has had similar issues recently.
At the end of the day, most of these tools are simply displaying NOAA data in the user friendly format.
