storm watch... (am.28.nov.12)>

I've just gone through all the latest weather data, models, charts and satellite pics, and it looks like there are no major changes to the current forecast.  All the information seems to remain consistent with regard to our approaching early winter storm system.

We've already got a good amount of high cloudiness across our area, which should alternate with some periods of sun as the day wears on.  Rain and snow showers should develop in the high mountains to our north as early as mid-afternoon or so, with precipitation chances increasing overnight and on Thursday.  I still think our best window of opportunity for picking up some measurable rainfall here in the immediate McLeod area will be from this evening until late Thursday night.  Computer models are taunting us with 1-2cm (0.4-0.8") amounts -- which is a heck of a lot, considering the very dry weather of the past 6-8 weeks. We shall see if we get anything close to that.  Thunder and lightning will be a possibility as well.

Of greater concern is the potential for HEAVY SNOW in the mountains above roughly 10,000ft (3000m).  I can't stress enough the necessity of being on top of weather developments for people thinking about crossing high passes (including Rohtang!!) between late this afternoon and early Friday morning.

Scroll down for the 5-day outlook, and check back here this evening around 6:30pm for a full update...
