sun-shower-sun... (am.13.may.12)>

We have haze and some thin, high cloudiness across the area at sunrise this morning.  There was no additional rainfall overnight, which leaves us with a 24 hour total of 0.16" (4mm).  My overnight low temperature here in the upper part of town has been 65.3F (18.5C).

Still not exactly a "cut-and-dried" weather scenario in the near future, with lingering disturbances in the upper-atmosphere continuing to drift across northern India.  Pockets of colder air aloft, combined with summer heat which remains precariously close to us just down the hill, will continue to provide a decent chance of a couple of showers and/or thunderstorms popping up.  As we saw yesterday, things can change very suddenly... from sunshine to a thunderstorm and back to sunshine again within an hour!  So just be prepared for those potentially radical swings.

It would take a steep, strong ridge of high pressure to completely erase the thundershower risk from the forecast... but I don't see that during the coming week.  The upper-level flow will remain marginally active, with occasional weak disturbances moving from west-to-east across the area.  May sunshine will be plentiful, but a sudden period of thundershowers every now and then can't be ruled out.  Temperatures are expected to climb back above normal as the week progresses...
