slowly evolving system... (pm.20.sep.15)>

Sunday's stats:

Low temp: 62.2F (16.8C)
High temp: 71.6F (22.0C)
Rainfall: 0.01" (less than 1mm)

There are some breaks in the clouds to the west-southwest, otherwise it's mostly cloudy at dusk this evening.  We started off this morning with a brief period of rain showers just after 7:00am, then had a mix of clouds and sun throughout the morning before the clouds took over during the afternoon hours.  There were a few more brief sprinkles and very light showers during the early afternoon, but as you can see from today's rainfall total, it was barely enough to measure.

The evolving weather system across northwest India is the sole reason the India Met Department has been holding off on declaring an official monsoon withdrawal.  A large batch of leftover tropical moisture is still sprawled just to our south, and it is expected to be drawn northward during the next couple of days as an upper-level disturbance and circulation center eases in from the west-northwest.  Models are still showing widespread rain development across nearly all of northwest India during the first half of this new week -- and there could be some pockets of locally heavy rain before late Wednesday.  It seems to me that the overall scenario is trending toward lower rainfall totals than the projections were suggesting just a day or two ago, but we'll just have to wait and see.  This is indeed an "autumn meets monsoon" kind of situation, so it will be interesting to watch.

A drier air mass will attempt to work its way in starting late Wednesday into Thursday, but there should be a taste of fall in the air as our temperatures cool off just a few degrees.
