over-performing disturbance... (am.27.jan.15)>

A light rain shower is in progress at dawn this morning, and I'm showing a temp of 37.2F (2.9C), which is also the overnight low.  Off-and-on rain showers have been occurring since the wee hours of the morning, and there have even been a couple of claps of thunder.  The rain gauge shows 0.22" (6mm) of precipitation as of 7:00am.

We've been anticipating this disturbance to sweep across northern India during the Monday night through Tuesday period, but I'll have to admit I'm a little surprised that it is amounting to this much.  The compact center of circulation is located over extreme northern Pakistan this morning, and though it's not a very robust system, it is accompanied by some much colder air aloft, and has also been able to lift what little moisture is available up against the mountain slopes and produce these scattered showers.  It looks like the rain/snow line is in a similar position to what it was during our storm system last week, which has kept accumulating snow well above McLeod Ganj once again.  We'll see if it stays there, or if it might manage to creep down a bit before things dry out later today.

The next disturbance in the rapid west-northwest flow in the upper atmosphere will ripple through here late Wednesday night into Thursday, but at this point, it also looks like it will bring only minor amounts of precipitation to our area.

Temperatures will remain fairly close to normal for the end of January, with a slight warm-up anticipated this weekend.  Check THE 7-DAY OUTLOOK on the tab above for specifics.
