longest days/shortest nights... (pm.19.jun.16)>

Sunday's stats:

Low temp: 65.8F (18.8C)
High temp: 74.6F (23.7C)
Rainfall: 0.32" (8mm)

With the summer solstice just a couple of days away, the sun is rising earlier and setting later than it does all year long.  And this evening at blogging time, the sun is still well above the horizon, as it battles patchy cloudiness and haze.  We've seen another day of variable periods of clouds and sun, with some short spells of fog thrown into the mix as well.  Already there were some thundershowers in the area at sunrise... but those fizzled out leaving us dry until about 2:45pm, when some fresh rain showers developed and hung around until around 4:15pm or so.  At least at my location in the upper part of town, rainfall today was much less than we saw yesterday during our major thunderstorm/downpour that occurred shortly after noon.  Humidity was up, however, averaging in the 75-78% range.

Weather discussions start to get rather repetitive as we tip-toe into the monsoon season, with a nearly dead upper-level flow allowing increasing amounts of tropical moisture to surge northwestward across the India subcontinent.  From here on, it will be just the slightest variations in the moisture-content of our air mass, coupled with little wiggles and circulations at the micro-scale level along the outer Himalayan ranges that determine frequency and intensity of shower/thunder development.  There will be days without measurable rainfall between now and the middle of September, but those will be relatively few and far between.

I'll refer you again to the SUMMER INTO MONSOON tab at the top of the page for more detailed info on the advance of official monsoon conditions.  That line has moved further today, and I'll be updating those specs later tonight.
