same general story... (pm.19.sep.14)>

Friday's stats:

Low temp: 63.1F (17.3C)
High temp: 73.9F (23.3C)
Rainfall: none

Well here we are this evening with our familiar cloud and fog scenario.  Every single day of this past week has been a minor variation on the early morning sun -- mid-day cloud development -- cloudy/foggy late afternoon and evening -- post-sunset clearing theme.  In spite of the cloud/fog challenges, we've had our fifth dry day in a row.  The last time that happened was during the first half of June.

The population of ferns clinging to tree trunks around our area has gone through a major transformation during the past five to seven days -- from lush green to brittle yellow.  This process is always a tell-tale natural sign that our monsoon season is fading away.

Satellite pics the last several days have shown a narrow band of thick clouds and fog developing right along the front slopes of the Dhauladhars, in response to lingering moisture which gets lifted and condensed by the late morning hours.  Computer models have been consistent in showing a further lowering of the moisture content of our air mass as we move into the new week -- so we shall see if that will make any kind of difference.  At the same time, there is some slightly cooler air expected to arrive in the upper-levels of the atmosphere, which could introduce a bit of instability over the weekend.  That means we still can't totally and absolutely rule out a shower or thundershower popping up at some point.
