cooling trend... (am.27.oct.13)>

It is mostly clear but a bit hazy again at sunrise this morning.  The temperature here at my location has matched the coolest of the season -- at 55.0F (12.8C), while humidity stands at 59%.  There has been no precipitation overnight, and none in the past six days.

A rather active upper-air pattern continues to evolve across the western Himalayas as the jet stream gradually sinks further southward, allowing slightly cooler air to seep southward as well.  Although there has been enough lingering moisture in the air to fuel cloud development around here during the afternoons, that moisture is insufficient to produce anything more than some widely scattered sprinkles/light showers along the mountains slopes, it seems.  The subtle interplay between the temperature of air masses at different levels of the atmosphere is what provides the dynamic for cloud and potential shower development, so that will be the thing to watch during the coming several days with this changing upper-level pattern.

There appears to be little chance of a warm-up as we finish off the month of October.  The trend will be toward cooler temps, especially at night, over the coming days.  Depending on the amount of sunshine we can retain, it should stay seasonably pleasant during the daylight hours.
