may or march?... (pm.12.may.13)>

*Update @ 9:35pm... The atmosphere has stabilized very rapidly in the last few hours.  Looks like we could have a quiet and dry night ahead.  It's very cool, though -- current temp is 55.9F (13.3C), but it will probably remain steady or even slowly rise overnight.

----------------------------------------------------------------------------------
Sunday's stats (updated at 8:03pm):

Low temp: 52.0F (11.1C) -- 2:35pm
High temp: 62.6F (17.0C) -- shortly after midnight
24 hour rainfall: 0.82" (2.1cm) -- 6pm Sat to 6pm Sun
Total rainfall since Friday night: 2.14" (5.4cm)

The nicest weather of the entire day is happening during this hour before sunset, as the rain has stopped and clouds are breaking up a bit.  We had nearly continuous light rain until about 3:30pm, which kept our temperatures way way way below normal for the middle of May.  I haven't checked all of my records yet, but I have a hard time remembering such a cold day so deep into the summer season.  A lot of new snow has fallen on the Dhauladhars since yesterday afternoon, which is also unusual for this time of year.

The culprit for this unseasonably cold and wet weather is an upper-level disturbance which has been moving very slowly across the western Himalayan region during the past 48 hours or so.  Its center of circulation has weakened considerably today, and will flatten out completely during the next 24 hours as it shifts further to the east.  That means we'll see a general improvement during the next day or two, as a strong ridge of high pressure begins to build just to our west over Afghanistan and Pakistan.  There's still a decent chance of a round or two of thundershowers between tonight and Tuesday, but the atmosphere should become more and more stable, while drier air begins to filter in from the west-northwest.

Temperatures are ridiculously below normal right now, but all indicators point toward an aggressive warming trend kicking in as early as tomorrow, and continuing throughout the coming week.  It's still looking hot and dry and definitely summery by the time the first IPL cricket match kicks off at HPCA Stadium in Dharamsala on Thursday evening.
