much improved... (am.23.dec.13)>

It's partly cloudy at sunrise this morning with a temp of around 41F (5C), after an overnight low of 39.6F (4.2C) here in the upper part of town.  A few off-and-on light rain showers lingered until just after 5am, which was longer than expected, delivering another 0.09" (2mm) to my rain gauge since last report.  That brings the storm total to 2.07" (5.3cm), which is almost exactly the average precipitation for the entire month of December.  This month we've apparently received it all in one shot!

Throughout the year there are weather systems that perform pretty much according to expectations, those that under-perform, and those that over-perform.  This one that brought us the copious amounts of rain and up-mountain snow over the weekend definitely falls strongly in the over-performance category.  Total precipitation amounts turned out to be double to triple the computer models' projections -- and I'm still not sure where that much moisture came from.  It seems that wind vectors throughout the atmosphere were simply oriented perfectly to lift/condense whatever moisture was available, and ring it all out here along the front ranges of the north Indian Himalayas.

At any rate, things have calmed down, and it looks like we'll have a stretch of much quieter weather for Christmas and beyond.  The upper-air pattern is still full of weak ripples and minor disturbances which will continue to flirt with northern India, but a sharp reduction in the moisture content of the air is expected this week, which should keep rain/snow chances very low.  Temperatures will moderate a bit, and average out in the 'near normal' category over the course of the coming week to 10 days or so.
