Steve Storm chaser, weather station technician, and internet domain admin This station's first weather page went live on the internet in January of 2004. Since then, home weather stations have become much more reliable, affordable, and now provide much more data than just basic temperature, wind, and rain measurements. ![]() Available 24x7 on 162.400 Mhz covering the south central Texas area ![]() Big thanks to Tom Keffer for writing the weeWX weather station engine and also to Matthew Wall and Gary Roderick for their invaluable contributions to weeWX. Get the whole saga of weeWX and the software at the link above. weeWX is relatively easy to configure and use even for those like me with limited programming experience. On June 26, 2017, I started with the basic HTML template that was included with weeWX and have watched this entire weather website's template grow to 2,413 lines of HTML over the last eight years. ![]() Thank You Elwood Downey, WB0OEW for your creation of the astronomical position calculations used in the Heavenly Bodies section of this website. Donating your libastro C calculation library for use in PyEphem for linux was a very gracious thing to do. Many people are grateful for your generosity and hard work on that project and so many others.
