a changeable sky... (am.26.may.12)>

It is mostly cloudy on this Saturday morning, with some light showers and a thundershower or two in the vicinity.  I first woke up hearing thunder and gusty winds just before 5:00am, but thus far, the rain gauge is showing barely 0.01" (much less than 1mm).  Temperatures were warm all night, but finally dropped to a low of 69.6F (20.9C), thanks to the thundershower.

A disturbance in the upper-atmosphere is to blame (or thank) for the cloudiness and thundershower activity.  This system will pivot across northern India, its center remaining well to our north, between now and Sunday mid-day, keeping us with the potential for a round or two of showers or thunderstorms.  I'll be surprised if we can get any significant rainfall out of this... although one computer model is hinting at a total of around 0.50" (1.3cm) by the time all is said and done.  There will still be periods of sunshine along with seasonably warm temps... just be on the lookout for thundershower development and be ready to take shelter if necessary.

The upper atmosphere will be shifting back into full-on summertime mode starting late Sunday and Monday.  Very warm air will return to the middle and upper-levels, getting rid of most of the instability necessary to trigger any thunderstorm action.  Expect very warm temps and plenty of sun for the majority of next week...
