minor shake-up... (pm.04.nov.12)>

Sunday's stats:

Early morning low temp: 52.3F (11.3C)
Afternoon high temp: 64.0F (17.8C)
Rainfall: none

Our skies are in the process of clearing out this evening, after a period of fairly extensive cloudiness which rapidly developed along the leading edge of the mountains around mid-day.  We continued our recent steady cooling trend today, despite the abundant sunshine up until the noon hour.

Increasingly disturbed weather aloft is now moving into northern India, which should remain with us into Tuesday.  At least one fairly well-formed upper-level low pressure center will move across the area, delivering much colder air in the higher levels of the atmosphere, and significantly cooler air here at the surface as well.  That colder air aloft will create enough instability to cause more extensive cloudiness during the next couple of days -- especially during the afternoon hours.  None of the computer models are forecasting measurable rainfall, but I think it's smart to keep a 20-30% chance of some widely scattered shower development on Monday and Tuesday as this system sweeps through.

Depending on cloud cover, temperatures will range from slightly to significantly cooler during at least the first half of the coming week.  We've been above normal for about a week now, but it looks like a return to historically "average" early November temperatures is likely...
