our wet feb... (am.21.feb.13)>

High clouds started moving in just after 4am this morning in association with an upper-level disturbance that is just a precursor of the storm system expected to develop and move across northern India this weekend.  My overnight low was 44.8F (7.1C), but it is currently 47.8F (8.8C), with humidity only 36%.

So far this week we've been dealing with wild swings between sunshine, clouds, fog and even some light rain showers -- thanks to an active, fast-moving jet stream overhead, along with an unstable air mass here along the mountains.  We should see a lot of high cloudiness today, along with a risk of a period of fog and perhaps a rain shower or two later in the day, once again.

The next round of significant rainfall will hold off until tomorrow (Fri) through Saturday night or early Sunday, as a deep trough of low pressure organizes just to our west.  The data this morning is still pointing to precipitation amounts averaging near 4cm (1.6"), which is very similar to what we received last weekend.  I've recorded 16.5cm (6.49") for the month of February up to this point, which is way above normal already.  It's looking like we could end up with double the amount of normal Feb rainfall.
