atmospheric wiggles... (pm.21.nov.12)>

Wednesday's stats:

Early morning low temp: 52.3F (11.3C)
Afternoon high temp: 59.5F (15.3C)
Rainfall: none

There was very little movement on the thermometer today, thanks to a broken layer of high clouds which persisted across the area.  We did get some glimpses of sun from late morning into the early afternoon, but the high clouds were definitely the dominant feature of the day, keeping us below the 60F mark for only the third time this season.

We're now in the midst of a string of upper-level disturbances which will be affecting us off-and-on through Saturday.  The jet stream is active, and embedded with several of these disturbances which will bring waves of cloudiness and perhaps some light precipitation to Himalayan north India as they pass through.  All the data points to the risk of measurable rain/snow to remain in the highest elevations, but there is still potential for us to pick up a few randoms sprinkles or a stray shower sometime before Sunday arrives.  There simply isn't enough moist and juicy air available to give us a promise of much more than that.

The bigger news is the colder air which is expected to flow in over the next two or three days.  It's likely that we'll experience the coldest temps of our early winter season by the weekend -- in fact, we should wind up a bit below normal, which hasn't happened very often thus far this season.
