t-shirt weather... (pm.29.apr.14)>

Tuesday's stats:

Low temp: 63.7F (17.6C)
High temp: 79.1F (26.2C)
Rainfall: none

There is some haze visible down in the valleys below, otherwise we have clear skies at sunset this evening.  It's been another sunny day, with only minor afternoon cumulus development over the mountains and a few high clouds at times.  My thermometer on Tushita Road just below the mountaineering center tried hard to touch 80F (26.7C) this afternoon, but didn't quite make it.  Still, it was the sixth day in a row on which I've registered a new high temperature for the season and the year.

A summer-like ridge of high pressure continues to dominate the weather pattern across northern India, providing us with stable conditions and an atmosphere that continues its incremental warm-up.  It's been a fine way to wind up the month of April, which has seen its fair share of wet and unseasonably chilly conditions.  We may be starting to run out of good fortune, however, as our air mass looks like it will begin destabilizing as we head toward the weekend.  A bit of additional warming in the lower layers of the atmosphere is not going to get along well with some slight cooling aloft, and that will set the stage for an increasing risk of some mainly afternoon/evening thundershower development over the mountains.  It will be interesting to see if much at all happens as these subtle changes take place during the next several days.

Otherwise, expect our recent warmth to stick around as we transition into May, with temps averaging out on the plus side of normal for a change.
