ultimate stability... (pm.16.apr.17)>

Sunday's stats:

Low temp: 66.7F (19.3C)
High temp: 84.2F (29.0C)
Rainfall: none

Maybe I missed it, but I never saw even one single cloud today, which made for wall-to-wall sunshine on this Easter Sunday 2017.  Our atmosphere was perfectly stable, and with very little moisture in this air mass, we had one of the few days over the course of the year around here with no cloudiness whatsoever.  And temperatures?  Well, again we achieved new maximums for the season and the year -- both the overnight low and the afternoon high.

Models have done a very good job since about a week ago, advertising this massive ridge of summertime high pressure which is now well-established from the Arabian Sea into the heart of the Indian subcontinent and even pushing well into the western half of the Himalayan region.  Of course this includes us, and is providing us with the kind of summer temperatures that fall into the normal/average range during the latter part of May into mid-June.  The big difference is that during late May into June, we are starting to deal with much higher humidity levels, which make these kinds of temps a lot more uncomfortable.

It will likely warm up even further between tomorrow (Mon) and Wednesday, but then a series of weak disturbances will drag in some gradually cooler air aloft... and that's going to lead to some destabilization of our atmosphere for the latter part of the week.  Mainly isolated PM showers/thunder will become a possibility as early as Wednesday, but more likely by next weekend, as temps begin to trend a bit cooler...
