An unusually potent upper-level high pressure ridge has provided us with a very stable atmosphere and unseasonably mild temperatures the last few days -- along with instigating a strong inversion which is trapping a shallow layer of colder air and smog in the lower elevations to our south on the plains of north India. Temperatures today cooled off just a bit, but yesterday and last night, temps were shockingly high for the dead-center of our winter season.
There is a pattern change on the way, however, in the form of a rather strong upper-level low pressure center now rolling into Afghanistan. This system will cause the high pressure ridge in place to collapse dramatically between Monday and early Wednesday -- allowing more seasonably cold air to spill into Himalayan north India. Unfortunately there still doesn't appear to be much of a moisture-tap available for this system, so only random and/or widely scattered light precipitation is expected -- between late Tuesday and about noon on Wednesday. I would love to report a change to that outlook, and will do so if rain/snow chances in our area start to look better.
