minimal rain risk... (am.05.may.13)>

*Update @ 8:12am... We're getting a few rumbles of thunder.  It will be interesting to see if even a light shower can be squeezed out of this very dry air mass.  Currently: 72.7F (22.6C), humidity: 31%.

--------------------------------------------------------------------------------
Last night was the warmest night of the year -- by far.  I recorded an early morning low temp of 68.2F (20.1C), which is actually closer to normal for the end of May.  We've had occasional clouds overnight and a period or two of gusty winds, as humidity has remained very close to 30%.

Some weak disturbances in the upper-atmosphere have begun to ripple across northern India, and that's the reason for the increased cloudiness this morning.  However, there is still a serious lack of moisture available to fuel any significant showers or thundershowers, despite the modest instability.  There is at least a mentionable chance of a period of showers today (Sun) into Monday, but I'm still skeptical about coming up with enough to measure in the rain gauge.  Otherwise, expect a mix of clouds and hazy sunshine as this system moves through.

A rather strong ridge of early summer high pressure will dominate our weather pattern starting on Tuesday.  This is going to provide temperatures a couple of degrees above normal for early May, while keeping rain chances at a bare minimum.  An increasingly stagnant air mass will be responsible for a lot of haze and trapped smoke/pollution as the week goes on.  This is the price we pay for the very low humidity and lack of significant rainfall.
