wiggling jet stream... (pm.12.jan.14)>

*Update @ 7:51pm... More than two hours after sunset, the temperature is 47.5F (8.6C), not much below the high temp of the day.  Milder air continues to push in.

------------------------------------------------
Sunday's stats:

Low temp: 39.7F (4.3C)
High temp: 48.7F (9.3C)
Precipitation: none

My high temp on Tushita Road below the mountaineering center failed to hit 50F (10C) this afternoon -- and that makes seven days in a row that we've stayed below that mark.  It felt milder to me today, but that's not what the thermometer said.  We did have a lot of high cloudiness across the area, with only some short periods of unrestricted sunshine here and there.  It remains mostly cloudy after sunset.

Although there are no major storm systems on the weather charts, our general pattern is going to be very fickle and changeable all the way through this week and into the weekend.  The jet stream is full of weak disturbances which will be moving across northern India, bringing occasional periods of cloudiness and even the risk of some rain showers.  Right now it looks like the best chance of precipitation will be in the higher mountains to our north and east (and that in the form of snow), but we could get a few showers around McLeod and vicinity tomorrow into Tuesday, with another pretty good chance of some measurable precipitation on Friday as well.  The snow line should remain well above us, the way the atmospheric temperature profile projections are shaping up.

I will say that there is a lot of shifting back-and-forth in the computer model data for the upcoming 10 days or so, which indicates that we're dealing with a very unsettled pattern.  Keep checking back here for any late-breaking changes.
