unstable period continues... (am.13.may.15)>

For the second night in a row, we've had significant rainfall here in McLeod Ganj.  My rain gauge is showing 0.53" (1.3cm) since last evening's report -- with most of that occurring between roughly 9pm and 1am.  I'm recording a low temp of 55.0F (12.8C), though currently we're hovering right around 62F (17C).  Our sky is partly cloudy at sunrise.

The center of a wobbling area of upper-level disturbances is over northern Pakistan this morning, and has been the 'driver' of our turbulent weather across northern India during the past 36 hours or so.  The big high pressure ridge which brought us very warm, stable and dry weather for many days is long gone, as much cooler air has established itself in the middle and upper-levels of the atmosphere -- and obviously here at the surface as well.  We've also got a rather moist air mass for this time of year sprawled across much of northwest India.  These conditions will remain with us today, and to a lesser extent tomorrow (Thu) as well.  That means there will continue to be scattered shower and thunderstorm development in our area during the coming 36 hours or so -- though we will likely see some periods of sun in between those bouts of thundershowers.  If we do get a couple of hours (or more) of sun, our temperatures will warm up nicely, but it's going to remain on the cool side of normal for this time of year... all the way through tomorrow.

The pattern will start changing dramatically again on Friday, as a new blast of warmer air comes in from the west.  There could still be an isolated afternoon thundershower on Friday, but overall, the atmosphere should trend toward greater stability over the weekend, along with a rapid return to very warm (and again above normal) temperatures.
