mountain instability... (pm.30.mar.13)>

Saturday's stats:

Early morning low temp: 50.9F (10.5C)
Afternoon high temp: 67.6F (19.8C)
Rainfall: trace

Thundershowers over the mountains have quickly dissipated early this evening, leaving us with clear to partly cloudy skies just before sunset.  We've had a really nice day here in the immediate McLeod Ganj area, but there were thundershowers with small hail just up-mountain from us starting around 1:15pm -- and it looks like there was a healthy dumping of new snow on the higher Dhauladhar peaks.

The flow in the upper-atmosphere is very light, but as expected, there remains enough cold air up there in the wake of our recently-departed upper-level disturbance to create unstable conditions during the afternoon hours.  That instability should diminish somewhat on Easter Sunday, but if you plan to be venturing up to Triund and beyond, be aware of the potential for a period of PM thundershowers once again.  Apart from that, things should be fairly quiet until about Tuesday afternoon, when the next disturbance will be dropping in from the northwest.  We may see a more general area of showers develop at that time, continuing through Wednesday.

I think our temperatures are on track to hit 70F (21.1C) early next week -- corresponding with the arrival of April.  Unfortunately, the milder weather won't last long, as a blast of cooler air will accompany that new disturbance during the middle of the week.
