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.

I notice that the Meteogroup (BBC) forecast is differing from the MetO one for Penzance today. 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.
