only brief showers... (pm.05.may.13)>

*Update @ 7:52pm... The temperature dipped to our low of the day (see below) at 5:25pm during that brief shower, but has recovered to 70F as of now -- an indication of how topsy-turvy our atmosphere is, thanks to the disturbance passing overhead.  Humidity spiked at 57% during the shower, but has dropped again to 30%.  Despite the dynamic energy passing through, this air mass is just too dry to provide us with significant rainfall.

Sunday's stats:

Low temp: 61.2F (16.2C) -- 5:25pm (updated)
High temp: 77.0F (25.0C) -- 3:05pm
Rainfall: trace

It's mostly cloudy and breezy this evening, as widely scattered thundershowers gradually dissipate.  We've had a lot of variety today, with clouds alternating with short stints of sunshine, and a few very brief periods of thunder and some very light sprinkles and showers.  The most recent occurred just before 5:30pm, but didn't last long enough to do anything more than wet the pavement.  As anticipated, the rainfall today has not been enough to even register in the rain gauge.

A disturbance in the upper atmosphere is to blame for today's unsettled conditions.  A fairly strong circulation aloft has provided the "lift" necessary to create instability, but there's simply not enough moisture available to give us more than these brief, light sprinkles and showers.  There's still a chance of some hit-and-miss showers through tomorrow (Mon), but I still don't expect any significant rainfall amounts... really not even enough to settle the dust for long.

Our warming trend has stalled for the moment, but it looks very likely that it will resume in earnest by Tuesday, and continue through Thursday.  A ridge of high pressure during that time frame will protect us from any shower action, but a new upper-level disturbance is expected to arrive on Friday, increasing the chance of yet another round of mainly light showers and/or thundershowers next weekend.  In the meantime, temperatures should balance out near to slightly above normal for early May.
