summer's intermission... (pm.03.jun.15)>

Wednesday's stats:

Low temp: 53.6F (12.0C)
High temp: 68.3F (20.2C) -- at 8:15pm!
Rainfall since 7:00am: trace
24 hour rainfall: 0.25"

Our sky is totally overcast this evening at sunset, as it has been for most of the day.  We did have some glimpses of sunshine this morning, but they were very short-lived.  On the other hand, the showers today have been few and far between, and very light.  There was a bit of thunder this morning, but compared to yesterday and last night, our rainfall has been sparse indeed.  With very limited sunshine our temperatures didn't go very far -- my official high temp in the upper part of town was the coolest I've recorded since way back on the 16th of April.!

The culprit of this major break in summertime weather is well known to those of you who follow this blog.  It's a sprawling area of low pressure in the upper atmosphere that has been anchored just to our west since Monday, and has moved very little in the past 36 hours or so.  Yes, it continues to weaken, but it has plenty of moisture drawn into its circulation -- and it's still a lot colder aloft than it is in the lower layers of the atmosphere, keeping things quite unstable all across northwest India.

The counter-clockwise circulation of this system isn't going anywhere for another day at least, but gradual warming is already occurring aloft, and that is going to cause our atmosphere to stabilize (very slowly) over the course of the next couple of days.  We'll have to be prepared for more hit-and-miss showers and thundershowers, periods of gusty winds, and also probably a good amount of cloudiness tomorrow (Thu), with just a slight chance of a shower or two on Friday.  THEN -- the computer models are showing a major warming trend as we move through the weekend into early next week, with only PM mountain thundershower potential.  I have to reiterate -- there's going to be more very warm summertime weather ahead...
