major seasonal shift... (pm.06.apr.13)>

Saturday's stats:

Early morning low temp: 53.6F (12.0C)
Afternoon high temp: 72.5F (22.5C) -- warmest of 2013 
Rainfall: none

Another nearly perfect evening is in progress, with clear skies and pleasant temperatures just before sunset.  Today turned out to be the warmest of our new spring/summer season, with our warming trend kicking in a little more rapidly and aggressively than expected.  Humidity has remained very low -- generally in the 35-45% range all day.

Major seasonal changes are in progress, as a rather strong ridge of high pressure continues to build across India.  At the same time, an intense upper-level storm system over the northern Persian Gulf will be moving eastward.  This combination of factors will cause warmer and warmer air to be pumped northward, bringing us the highest temps of this year by far, but also increasing the moisture content of the air by fits and starts.  A preliminary burst of energy and moisture is still expected to move across northern India on Sunday, and that will probably generate a few more clouds than we've seen in the last few days, while giving us a chance of a couple of thundershowers mainly higher up in the mountains.

That Persian Gulf system itself will die out almost completely by the time it nudges into northwest India on Wednesday.  However, we will see an increase in shower potential for the mid-week period, even if it doesn't look like a notable amount of moisture at this point.  I can't say with absolute certainty just yet, but it seems that we may be safely into a pattern that will keep our temperatures close to where they should be for this time of year for a while.
