stability in jeopardy... (pm.25.may.12)>

Our skies are partly cloudy this evening, but it was mostly sunny until mid-afternoon, which allowed my high temp on Tushita Road up at the top of McLeod Ganj to reach 89.4F (31.9C).  That is the new high for the month, the season and the year.  Had the clouds held off for another couple of hours, we would have been well above 90F/32C.

Those clouds developed/moved in pretty much right on schedule, in advance of an upper-level disturbance that will be influencing our weather for at least the first half of the weekend.  This system is now moving into northern Pakistan, and will swing across north India by early Sunday, destabilizing our air mass, and bringing us at least a mentionable chance of a round or two of showers and thunderstorms.  We may be dealing with more thunder, lightning and wind -- and not so much rainfall -- but the situation bears watching during the coming 36-48 hours or so.  Pre-dawn thunderstorm winds lifted the roof off of a house up at Triund earlier this week, so we know things can get nasty even if there isn't a lot of rain involved.

General high pressure aloft will rebuild into the area by Monday, which will set us up for another stretch of dry and very warm weather for most of the coming week.  At this point, there is not even the slightest hint of an early transition into monsoon season!
