OK did the update and installed. We might get some rain later today, so we might have results by tomorrow.
I installed the latest just over an hour ago, and I see that Xastir is still showing the Total Rain field as empty at this point. Prior to this AM, there would have been a number there by now, so we will see what we get. Regarding the differences in rainfall between nearby sites here, that is just the way that the weather is here in subtropical Orlando. Each Wx station could be identical and be perfectly sited and there would still noticeable differences between nearby locations. That is why we do not get too wrapped up in differences of hundredths or even tenths of an inch here. Of course in other parts of the world, it is a different story.
