30" for august... (am.22.aug.13)>

Apparently there was a light shower overnight, because I have 0.04" (1mm) in my rain gauge this morning.  We have now surpassed 30" (76cm) of total rainfall for the month of August -- and we still have ten days to go.

Early this morning it is cloudy with humidity near 100%.  The temperature is just a bit warmer than I've recorded at this time of the morning during the past couple of weeks -- 66F (18.9C).  There's not much sign of fog OR sunshine so far today.

Although we've had some notable periods of sun the last couple of days, we're still getting some hefty downpours of rain that have kept the monsoon rainfall tally ticking upward.  More of that kind of variety is in store today, and into at least the first part of the weekend, with clouds alternating with sun and periods of rain showers and possible thunder.  A fairly significant retreat of monsoon moisture is being hinted at by computer models by late Saturday into Monday of next week, as some drier air attempts to push in from the west and northwest.  This is not yet the kind of dry air intrusion that will chase the tropical moisture away for good, but it is a sign of things to come.

I saw last night that the IMD monsoon page has finally updated their maps for average withdrawal date of the monsoon across India.  We are now in the 17-18 September range, which is a little more realistic, since official withdrawal each year since 2005 has been during the last week of September.
