more PM thunder?... (am.06.apr.12)>

We're back to clear skies just before sunrise on this Friday morning.  I'm recording the coolest overnight low temp since Thursday, 29 March... 59.5F (15.3C)... which is actually pretty close to normal for this time of year. There has been no additional rainfall since yesterday, so our 24 hour total remains at 0.48" (1.2cm).

That half-inch of rain was also the first measurable precipitation since 13 March... so despite the fact that it came along with a lot of thunder and lightning (and wind), it was a very welcome shot of moisture.  Can we get more today?  That is the burning question.  The instability that generated that round of thunderstorms yesterday afternoon remains in place today... but it is likely we won't warm up quite so much here at the surface, which may diminish our chances of such a dramatic display.  Still... we'll have to keep an eye out.

Over the weekend, slightly warmer air will return to the mid- and upper-levels of the atmosphere, which should also contribute to a bit of stabilization.  However, there is a fairly strong-looking upper-air disturbance and associated pool of cold air aloft on its way for Monday into Tuesday.  That will increase our chance of some shower and thunderstorm activity once again.  Temperatures are expected to remain on the warm side of normal right into early next week...
