quite calm for now... (am.27.jun.15)>

It's a sunny and pleasantly warm Saturday morning, with the humidity reading right around 60%.  The overnight low at dawn was 62.4F (16.9C), but already it's warming rapidly.  I've recorded no rainfall since last report.

The air mass is doing some shifting around again, as much warmer air invades in the mid- and upper-levels of the atmosphere the next couple of days.  The models are showing absolutely no shower/thunder development either today or tomorrow -- but I think we still have to be on guard for the potential of a thundershower during the mid-day or afternoon hours, in the midst of sunshine/cloud fluctuations.  Temperatures both today and Sunday should be warmer than we've seen in a bit more than a week.

Tropical moisture which was pushed southeast of us on Thursday will start to sneak northwestward along the front slopes of the mountains by late Sunday, and that's going to set us up for an increasing chance of some periods of rain and thunder as early as Sunday night -- and then continuing off and on for most of next week.  Our humidity has yet to reach the levels we would expect during monsoon season -- but we may get there as July arrives.
