atmosphere unresolved... (am.17.apr.13)>

Our Wednesday morning is dawning with clear skies, pleasant temperatures and low humidity.  My overnight low here in the upper part of town was 58.1F (14.5C), and there has been no additional rainfall since the last batch of showers moved out just before 5pm last evening.  Total rainfall from all of yesterday's action was just 0.13" (3mm) -- not much to show for all the trouble!

Although it's bright and sunny early this morning, the air above 15,000ft or so is unusually cold for this time of year, and that's going to bring the instability issues into question by the afternoon.  As the sun warms things up, we'll likely see a build-up of clouds over the mountains, which could lead to a round of thundershowers.  This whole routine is actually more frequent than not during this time of the year -- just be prepared to run for cover if necessary during the mid- to late afternoon hours.

A ridge of high pressure should take over on Thursday and Friday, however, with a more stable atmosphere expected to provide us with plenty of sun and only a slight chance of one of those PM thundershowers.  Temperatures are running slightly below normal for mid-April, as the average high is now approaching 76F (24C), but we'll most likely be close to that once again by the end of the week.
