warming just a bit... (pm.7.apr.11)>

it's turning into a nice evening... after a day that has been pretty much equally split between sun and clouds.  the morning was glorious, but thick clouds developed over the mountains during the afternoon, which led to some random sprinkles and even a couple of rumbles of thunder between 2 and 4pm.  the high temp reached 66.4F (19.1C)... better than yesterday, but still a good 8F (4C) below normal for this time of year.

we should see another incremental improvement tomorrow... as temperatures warm a bit both at the surface and aloft.  the relationship between surface and upper-air temps will keep things marginally unstable, which means there could be another build-up of clouds over the mountains and a brief period of thunder/sprinkles during the afternoon.  also, batches of high clouds are showing up to our west, and those will dim the sunshine from time to time.

by saturday, we'll start to be influenced by the next disturbance in the jetstream pattern, which will gradually increase the chance of scattered showers and thunderstorms.  right now, i think the best chance of rain will come between saturday evening and monday afternoon.  with the arrival of this next disturbance, i see little chance of our temps warming into the range of "normal" during the next several days.
