The Canadians are a great people having model runs like this…

Check it out for AZ and the SW!  Will the drought be over in a week?  This could be the best model run I have ever seen and that’s why I have links to it twice in one line even though it is based on data from yesterday morning, the 1st.  (It will be replaced later this morning, but how can the next run be better than this one?)  Note all the rain (colored regions in the lower right panel) valid for Tuesday afternoon (Wednesday at “00Z”)!  I got goosebumps looking at this.  Note, too, upper low center over El Centro, CA, (upper left panel), a great spot for a good rain dump here in Cat Land.

Some of yesterday evening’s threatening clouds are shown below.  Note distant rainshaft indicating a much taller top, a “Cumulonimbus” (Cb) embedded in these layer clouds.  Sadly, not one Cb passed over Catalina last night.  Only a trace came down from those threatening skies.  Too much dry air between us and them clouds is what done it.  However, this morning, dewpoints at the ground are up all over southern Arizony and with that, the likelihood that more rain will reach the ground.

The End for now…
