a shot at some precipitation... (pm.22.jan.18)>

It's been noticeably cooler the last 24 hours, as the high pressure ridge responsible for a big bubble of very mild temperatures in the mid-levels of the atmosphere breaks down.  An upper-level low pressure circulation moving into central Pakistan tonight is the culprit, and this system will be pushing into Rajasthan by tomorrow (Tue) morning, and then into western Nepal by Wednesday morning.  We're already getting a preliminary taste of some colder air, but we can expect temps to fall even further as the week goes on.

There's not much moisture being pulled into this system, but the last few runs of various computer models are showing a little better chance of a period or two of some light to moderate precipitation in our general area between Tuesday afternoon and Wednesday morning.  At this point, it's looking like there's a chance of some heavier rain showers to our south, and some heavier rain/snow to our east, lasting through Wednesday.  This is NOT a major storm system, but it's more excitement than we've seen since the middle of December, so it's worth watching.
