Some big patches of high clouds have been spreading into the area from the west this afternoon and evening, but still, I would call it partly cloudy just after sunset.  Despite the high, thin cirrus clouds, hazy sunshine was the main player today, and kept things pleasant for the most part -- with temps still a bit below normal for early November.  Humidity remained mainly in the 40-55% range.

These high clouds are the harbinger of less pleasant things to come during the next several days.  A large area of low pressure in the upper atmosphere is now starting to come together over Afghanistan, and will strengthen as it moves slowly eastward to northern Pakistan during the next 36 hours or so.  Ahead of it, winds in the mid-levels and aloft will start to turn to the southwest, tapping into some moisture from the Arabian Sea.  These factors will set the stage for an early winter-type storm system for a wide area across the western Himalayan region.

Tomorrow (Tuesday) should still be OK for the most part, although we may start to see some shower development in the higher elevations.  The best chance of significant wet weather right now looks like it will be concentrated during the  late Wednesday/Thursday time frame -- when we could see some thunderstorms, very strong and gusty winds, along with tumbling temperatures which will probably take us to new lows for the season.  And I certainly hope the travel back and forth across the mountain passes has, or will have, come to an end -- since moderate to heavy snowfall and sub-freezing temps will be likely up there.  This scenario is abnormal for the first half of November... but then again... nearly everything weather-wise around here the last 5-6 months has been strange.
