Some showers; then dry again.

The Southland did finally manage to see some rainfall with last night’s system, though it was less than 0.5 inches in most places. About a foot of late-night snow fell in the northern Sierras, which is a step in the right direction. All in all, however, this system did not live up to its true rainfall defecit-busting potential. A weak disturbance will move into CA later tomorrow, bringing some more showers and possibly an isolated thunderstorm, mainly in the north. Any additional rainfall will generally be light, though. The rest of the week looks quite warm in SoCal and possibly as far north as the Bay Area. Los Angeles could make a run at 80 degree weather once again (this is February, right?). The good news is that the ridge that will build in on Wednesday will be nowhere near as tenacious or long-lived as the one that preceded it. The PNA is forecast to become negative again during the second half of the month, which, although it does not bode well for heavy rain events, does indicate at least a slightly active pattern. The most likely outcome: a parade of colder, moist storms from the northwest, bringing brief bursts of rain and wind and heralding several decent rounds of post-frontal convective activity (which have been conspicuously absent thus far this rainy season). This rain would probably not occur until next week, however (7-9 days). So…it still looks like a dry year, but probably not to a disastrous extent.
