split-personality... (pm.24.apr.12)>

Skies are cloudy this evening, and we've had thunder rumbling around the area since about 3:00pm.  Still, I haven't personally witnessed one single drop of rain.  Abundant sunshine from the morning into the early afternoon allowed our high temp to reach 78.3F (25.7F)... but we've since cooled down, thanks to the clouds.

I'm really impressed with the continuing instability of our springtime air mass.  Warming in the lowest levels of the atmosphere during the first half of the day has been in conflict with the pools of much colder air which remain entrenched aloft.  Warm air -- by its very nature -- must rise... and when there is substantially colder air just above, the result is angry-looking cumulus clouds.  Satellite photos show scattered thundershowers again this evening all along the outer Himalayan ranges, but due to a lack of deep, rich moisture, it seems that there has been more thunder than rainfall being reported.

We should be repeating this general scenario on each of the coming few days... so continue to expect nice periods of sunshine (mainly in the morning), followed by the risk of a thundershower or two (mainly in the PM hours).  Our temperatures, thankfully, are firmly in the pleasantly warm realm... and should remain there until the weekend.

There may be a rise in the chance of significant rainfall also over the weekend... along with a dip in temps.  Check back here for updates...
