Wednesday was my sixth day job shadowing at the Albuquerque NWS Office. Originally, I was to learn about fire weather and aviation weather on this day, but the full extent of the monsoon season prevented that. Instead, I got to watch the full process of determining the need for a flash flood watch and how it is issued.
I have underestimated the importance of precipitable water in my past understanding. It integrates the total water in the vertical column above each point, and the number represented indicates how much water could fall from this vertical column. It will not show you a rainfall total, however, as much of the moisture available in that vertical column will not reach the ground. It also does nit account for storm motion. A system where multiple cells train one behind the other could have a higher rainfall total than a simple precipitable water calculation would yield.
Today was beautiful weather as we drove across southern Missouri. I warehouses the air conditioner, riding with the windows down most of the way.
I hope you enjoyed this post.
