unseasonable warmth... (am.30.jun.12)>

Hazy sunshine is in control early this Saturday morning.  There has been no rainfall overnight, and I recorded a low temp of 71.2F (21.8C).

An extensive area of high pressure in the middle and upper levels of the atmosphere covers all of the western Himalayan region, and should be our main weather feature for the next few days.  Although there is some pre-monsoon moisture/humidity in the lowest layers, it is dry and very warm aloft, and that should prevent widespread instability -- that means it will be hard to come up with anything more than perhaps an isolated thundershower in the mountains during the PM hours.  Apart from the moderate humidity, it is going to feel much more like early June than the June/July transition between now and Tuesday, with temperatures well above normal for this time of year.

This morning's computer model data continues to show an aggressive advance of monsoon conditions north and westward from Uttar Pradesh and Nepal by the middle of the coming week.  If things continue to develop the way the forecast models are indicating, we should see some radical changes around here starting as early as Wednesday, and especially by Thursday and Friday.  By one week from now, we may actually be immersed in genuine monsoon conditions...
