a different air mass... (pm.26.dec.15)>

Saturday's stats:

Low temp: 43.7F (6.5C)
High temp: 55.0F (12.8C)
Rainfall: none

There's a fairly uniform layer of high clouds blanketing the area just after sunset this evening, though a sliver of fading light is visible off to the southwest.  We were able to enjoy some fantastic bright and sunny skies with minimal cloud issues all the way until around 1:00pm, but then there was a very rapid increase in that high cloudiness spreading in from the west, giving us rather gloomy conditions for much of the remainder of the day.  The expected rise in temperatures did indeed occur, with the high temp at my location in the upper part of town reaching the warmest since the 9th of this month -- 17 days ago.

As we discussed this time last evening, there are two main things happening at the moment.  One, an extensive mass of much milder air is pressing deeper into India from the southwest.  Two, a rather strong pulse of upper-level energy is moving rapidly into and across the western Himalayan region.  We saw the effects of both today, with the very noticeable bump in temperatures, and also the significant increase in cloudiness during the afternoon.  We still have to be on guard for a couple of random light rain showers somewhere around the area tonight into tomorrow (Sun) morning, but as we've been anticipating, the best risk of some measurable rain/snow will remain in higher elevations to our north and east.

This milder air mass should stick around all the way through the coming week, with temps likely to be a few degrees (at least) warmer than we would normally expect during the tail-end of December.  Weak ripples in the upper-level flow will keep us dealing with periods of clouds from time to time, but there should also be plenty of sunshine to go around, with very little risk of precipitation until after the new year arrives...
