Not a lot of people know this - Washington has its own fully automated computer controlled weather station which constantly logs the temperature, wind direction, wind speed, barometric pressure and rainfall. Computer generated graphs are then plotted on demand and the results uploaded to this web site on a weekly basis. The graph shown below is the most recent available. Unfortunately due to building work currently being carried out, the weather station  has been dismantled for a while so the graph shown is for representation purposes only!
