major turn of events... (pm.13.feb.14)>

*Update @ 12:38am... Already there were some light rain showers trying to develop around 10pm, and now, there is steady, moderate rain here at my location.  The temp has dropped to 41.5F (5.3C).  This precipitation development is several hours ahead of schedule...

-------------------------------------------------------
Thursday's stats:

Low temp: 42.4F (5.8C)
High temp: 53.4F (11.9C)
Precipitation: none

Patchy mid- and high clouds have been rapidly developing during the past hour or so, here at the end of another beautiful sunny day.  Today's high at my location in the upper part of town was the warmest since the first couple of days of the month, but still a degree or two (C) below normal for the middle of February.  Still, it felt really nice, especially if you had a chance to lounge in the sun.  Humidity all day has been mainly in the 40-50% range.

OK -- now on to the next thing.  After just sifting through all the latest data, I am tempted to bang the drums and blow the trumpets and shout from the rooftops.  There are now three out of four computer models in agreement that we are in for a very impressive winter storm scenario between tomorrow morning and late Saturday.  One model is somehow holding off on major rain/snow development here, and keeping the deepest moisture just east of us.  The main factors consist of an upper-level disturbance and circulation which is now over extreme southeastern Iran, a fresh batch of very cold central Asian air sagging southward into northern India, and a concentrated flow of tropical moisture being drawn northward from central into northern India at this very moment.  According to the latest data, all three of these ingredients will be converging right on top of Himachal Pradesh during the next 24 hours.

Precipitation is expected to break out sometime after midnight just to our south, with an increasing chance of wet weather for us by late morning tomorrow (Fri).  With the upper-level system moving very slowly, we could have periods of moderate to heavy precipitation all the way into Saturday afternoon.  This year we have managed to miss out on accumulating snowfall here in McLeod, but according to the data, we should be squarely on the cold side of the equation, giving us the best chance of snow of this winter season.  I tend to be a skeptic, but I also try to be a realist -- and I have to be honest and say that the latest data looks daunting.  We've got a whole lot to watch!!

All of you obsessed and addicted weathergeeks out there know very well that things can change quickly and unexpectedly around here... so just be prepared, and check back for the latest discussions of developments...
