sun, maybe thunder... (am.27.may.14)>

We're starting off with full sunshine again this morning, after a clear and quiet night with no rainfall.  My low temperature here on Tushita Road below the mountaineering center has been 62.6F (17.0C), which occurred just before sunrise.  The current humidity reading is 40%.

The main characters are still in play in our weather scenario -- a sprawling ridge of high pressure parked to our southwest, with a northwesterly flow in the upper-atmosphere across northern India.  Weak disturbances in that northwesterly flow have triggered isolated to widely scattered afternoon thundershowers on a daily basis in the mountains from Kashmir into Himachal, and we'll have to be aware of that potential again later today.  These things are very hit-and-miss, but when we get hit, we get hit!  Otherwise expect lots of sun, at least during the first half of the day.

The dramatic warm-up we've been anticipating for the latter half of the week still appears to be on schedule.  That big high pressure ridge will attempt to poke further into western/northwestern India, stabilizing our atmosphere a bit, and delivering the warmest temperatures of this entire season and year.  We may be eyeing something close to 90F/32C by Friday or Saturday.  However, a new disturbance could increase our risk of showers and thunderstorms over the weekend...
