pre-monsoon moodiness... (am.28.jun.12)>

It's another very pleasant morning, with sunshine and a few clouds at this early hour.  There has been no additional rainfall overnight, and I recorded an overnight low of 68.2F (20.1C).  Yesterday's 1.70" (4.3cm) deluge brings us up to 5.18" (13.2cm) for the month of June, which is still more than 3 inches below normal.

Can we expect another huge downpour today?  Moderate humidity lingers, but there are indications that the atmosphere may start to stabilize a bit during the coming few days.  Still, due to the strong heating of the sun and that lingering low-level moisture, I think it's wise to keep in mind the potential for a rapidly developing thundershower again -- not only today, but tomorrow and Saturday as well.  As we've witnessed first-hand, we've reached the time of year when we can pick up a tremendous amount of rain in a short period of time... and then return to full sunshine very quickly.  Pre-monsoon schizophrenia.

For the past several days, the computer models have been very consistent in drying things out and warming things up significantly over the weekend into early next week, as a high pressure ridge strengthens over northern India.  This kind of pattern is very unsual for the first days of July, and should keep the northern limit of the monsoon from advancing in our direction for a while longer yet...
