What happened?

That computer models have taken over the production of day-to-day weather charts has become an established fact.
Such models rely on a regular, constant inflow of data from observation stations, satellite images and more recently automatic stations both on land and at sea (buoys).
 Observational work at manned weather stations has unfortunately declined.
Satellite detail does seem to be selective in what comes through in ranges of clarity.
 Automatic stations require close (on hand) monitoring. Buoys, away from the dustiness of land, come through quite well. But it all boils down to accuracy.
