clinging to summer... (pm.16.jun.15)>

Tuesday's stats:

Low temp: 63.9F (17.7C)
High temp: 83.6F (28.7C)
Rainfall: none

There's a broad bank of mid-level clouds hovering along the Dhauladhars at sunset this evening, with mainly clear skies to the south.  Our expected warm-up did indeed kick in today, with my high temp in the upper part of town more than 10ºF (5ºC) warmer than yesterday's.  Our sky hasn't been totally cloud-free, as there have been attempts at development over the mountains since the late morning, but none of it ever really took hold.  I never saw any raindrops at all -- basically a very nice and warm mid-June day.

I was a little surprised that our next weather feature -- a strong high pressure ridge -- exerted its influence so strongly today.  It will continue to build in from the west-southwest during most of the remainder of this week, furnishing some very warm air in the mid- and upper-levels of the atmosphere that will really put a damper on our recent cycles of afternoon, evening and overnight instability.  We can't absolutely rule out an isolated thundershower or two at some point, but the vast majority of our hours will be dry and quiet, with plenty of daytime sunshine.  Based on the major warm-up today, I am more confident that we're going to be challenging the warmest temperatures of the season and the year between tomorrow and Friday or Saturday.  And with humidity on the rise by the end of the week, that's going to spell some uncomfortably muggy conditions for us.

Thereafter, we have to face our first real surge of juicy tropical moisture ahead of the monsoon's advance -- by Saturday night or Sunday.  Right now the models are showing some significant rain and thunderstorm development happening by then, which could continue off and on during at least the early part of next week.
