ready for anything... (am.23.apr.13)>

*Update @ 3:18pm... Mid-day/early afternoon thundershowers produced just 0.07" (2mm) of rain here on Tushita Road just below the mountaineering center.  The clouds which developed very rapidly during the mid-morning have cleared out, leaving us with a good amount of sunshine as of this moment.  Could yet be more sudden changes before the day is done.

--------------------------------------------------------------------------------
We're starting off with hazy sunshine early on this Tuesday morning -- looking good.  Humidity is 62%, and I've recorded a pre-dawn low temperature of 55.2F (12.9C), with no rainfall recorded overnight.

High pressure is trying to rebuild across northern India, but will be hampered by occasional upper-level disturbances drifting in from the west-southwest during the next few days.  The first disturbance triggered our rain/thunder on Sunday, as it coincided with the arrival of this rather moist airmass.  The second disturbance brought us the cloudiness and brief sprinkles yesterday, and it looks like the next one will begin to move in this afternoon.  Moisture is still in place, but as temperatures aloft continue to warm up, the amount of instability is going to be questionable.  Just be aware that this atmosphere and overall weather pattern remain fickle and changeable, with the risk of thundershower development virtually anytime, but most likely in the afternoon/evening hours.

We've been languishing in unseasonably chilly air since the rain on Sunday morning, but we should break through today, as a nice warming trend kicks in for the remainder of the week into the weekend.  In fact, it's looking like most of this moisture will retreat by Saturday, with temps rising to their warmest of the season.
