coaxing the changes... (am.21.apr.14)>

There are a few thin wisps of high cirrus clouds at sunrise this morning, otherwise it is mostly clear and looking good.  My overnight low temp here on Tushita Road just below the mountaineering center has been 55.9F (13.3C), with no rainfall since last report.  Humidity this morning is 33%.

We're in one of those stages when fundamental shifts are happening -- changing the basic nature and character of the atmosphere.  The weather charts are looking much different during the remaining ten days of the month, as much warmer air finally claims territory further northward not only at the surface, but into the middle and upper-levels of the atmosphere as well.  What this means in practical terms for us is still a bit hard to say.  There will remain the potential for some periods of instability here along the front ranges of the Himalayas -- so we have to continue to be on guard for the build-up of clouds over the mountains during the PM hours, and the risk of some shower/thunder development up there as well.  There could also be some periods of high clouds this week which could put a damper on our late April sunshine at times.

But having said all that, the trend will definitely be toward more of a late spring and even early summer-like feel as we progress toward the weekend.  Temperatures are on track to get into the mid-70s(F)/23-24(C) in the near future, which will be the first time that's happened at my location in more than six months.
