Old retired guys like me, who learned our meteorology initially during a time of hand-plotted synoptic maps, the absence of the data provided by satellites, the absence of personal computers and the Internet – when bulky weather thermo-fax machines were considered a high-tech way to communicate and telephones were still dial models find today’s technology fascinating, miraculous, and extremely exciting.  Most of us feel so very lucky to be able to glimpse at these new marvels.  Many of us fantasize about how great it would have been to be able to do our work with such tools.  A few of us, (like myself) are lucky enough to be able to continue teaching (albeit on a small scale) using much of the information that is now easily accessible on line.  In my case I am able to project on line images on a big screen in the classroom.  I will never cease to be amazed by it.

Whenever I watch a water vapor loop I pause for a moment and marvel over how I am able to do something that at one time I never dreamed would be possible.  I can actually watch images of the very recent movement of air using a marker that is invisible to the naked eye, the water vapor molecule!

The willingness of computer-savvy weather enthusiasts to share what they do and what they learn gives me hope for the future.  I love this freedom that we have and the ease with which we can communicate.

On that note, here’s a little sharing from me of a page I enjoy.  It is a 72 hour weather forecast graphic LOOP from the University of Washington Department of Atmospheric Science.  It shows the plots for surface pressure (msl) and 500 millibars as well as an interesting precipitation forecast.  Enjoy.
