morning vs. afternoon... (am.21.may.14)>

We have clear skies as the sun peeks over the Dhauladhars early this morning.  I'm recording a predawn low temperature of 60.1F (15.6C), and there has been no additional rainfall since the 0.37" (9mm) which occurred last evening between 5:30 and 7:00pm.  The humidity reading is currently 40%.

There are no major features on the weather charts right now, but microscale instability factors are in play here along the outer Himalayan ranges as warmer air continues to attempt to surge northward in the surface layers, while pockets of cold air drift through aloft.  That instability reached the tipping point last evening, resulting in the eruption of thundershowers in our neighborhood for the first time in just over a week.  It appears that it will be a bit more stable overall today through Thursday, but as we always talk about here on this blog -- it's a good idea to be prepared for sudden changes during the PM hours if you're planning to be out and about.  Otherwise, a good amount of sunshine in the next couple of days could boost our temperatures a bit higher than they've been recently.

A weak but broad upper-level circulation is expected to settle in just to our west-northwest this weekend, which may set us up for a few days of scattered shower and thunderstorm action across much of Himachal Pradesh.  It won't rain continuously over the weekend, but the chance of more frequent showers/thunder looks higher between Friday afternoon and at least Sunday evening into perhaps Monday as well.
