sky always changing... (pm.14.jun.15)>

Sunday's stats: 

Low temp: 60.6F (15.9C)
High temp: 73.2F (22.9C)
Rainfall: 0.13" (3mm)

Our evening sky is partly to mostly cloudy, here at the end of yet another day of lots of fluctuations between clouds and sun.  Nice sunshine early this morning was quickly replaced with rapid cloud development over the mountains by 10:00am or so, with the first light rain showers appearing not long after 11:00am.  We then had a few short periods of showers/thunder into the early afternoon, with the sun breaking out again almost exactly at 2:00pm.  Temperatures were several degrees below expectations, and also well below normal for mid-June.

The weather scenario is going to be interesting this week, with dynamic atmospheric changes occurring as we continue to transition from Himalayan summer into the early stages of the monsoon season.  In the near term, we're dealing with a northwesterly flow which is bringing in cooler than anticipated temperatures in the mid- and upper-levels.  This of course is not compatible with strong June sunshine and an increasingly moisture-laden air mass creeping into northern India.  That's why we're having these daily doses of showers and/or thunder for a couple of hours every day.  It's unstable, and will remain so through tomorrow (Mon) and even tomorrow night -- with more isolated to scattered thundershower development a good bet.

An impressive-looking bubble of much warmer air is building to our west-southwest however, and should push in during the mid-week period.  Right now it appears that we could have a few days of more stable conditions, but also a return to much warmer temperatures and more noticeable and uncomfortable humidity levels.  And then... there could be a turn to heavier rain potential by about one week from now.
