a cold morning... (am.27.dec.13)>

*Update @ 9:12am...  Lots of sun this morning, but it is breezy out there at the moment, making it feel even colder if you don't happen to be in the direct sun.  My temp currently 43.1F (6.2C).

------------------------------------------------------------------
It's been one of the coldest nights of the season -- I've recorded a low temp of 38.8F (3.8C) here at my house on Tushita Road just below the mountaineering center, which occurred just before sunrise.  Skies are clear this morning, and humidity stands at 45%.

Surges of colder air continue to occur across the western Himalayas, as weak disturbances in the upper-atmosphere wobble eastward.  The latest such disturbance moved through late yesterday with temperatures cooling off a couple of degrees (C) in its wake.  There's still not much moisture for the atmosphere to work with, so despite the parade of upper-level wiggles and ripples, precipitation chances will remain very slim as we head into and through the weekend.  Temps will remain close to normal for the tail-end of December, but could moderate a bit toward Sunday.

I'm watching with interest a rather strong upper-level circulation which will be approaching northwest Afghanistan during the next 12-18 hours.  Computer models are showing this system slowly edging its way toward the Pakistan/Kashmir border by New Year's Eve (Tuesday) -- but then are still showing a rapid dissipation thereafter.  In fact, it is projected to completely fall apart as what's left of it moves across northern India on New Year's Day (Wed).  It does look like there will be a good chance of some rain shower development on Tuesday, with snow in the higher elevation -- so continue to monitor developments here, as new data comes in.
