sunshine dominates... (am.21.nov.13)>

It's slightly cooler this morning than it has been the last few mornings -- around 51F (11C) at my location just below the mountaineering center.  There's still a subtle temperature inversion in place, which means nighttime/early morning temps are a couple of degrees cooler further downhill.  We're starting off with clear skies again, and should see lots of sunshine again today.

A very fast moving upper-level disturbance is pivoting into western China early this morning, as slightly cooler air throughout all layers of the atmosphere continues to filter southward in its wake.  'Slightly' is the operative word here, as we're not really going to be dropping even below normal for this stage of November.  Very quickly, a ridge of high pressure will develop over northern India tomorrow, triggering another warm-up which will occur as we head into the weekend.

This very progressive pattern will then deliver a disturbance riding in from the west -- but it's expected to flatten out and dissipate by late Sunday/Monday as it encounters the ridge of high pressure in place over north India.  I think we could see a couple of waves of mainly high cloudiness during the weekend into early next week, but it appears that rainfall will be unlikely.  The dry season is finally behaving like the dry season.
