Weatherblogging
Haven't done nearly enough of this these past couple years....
Let's take a look at the overnight forecast discussion from the Boulder NWS office:
We had our first real snowfall of the season last night. It was only about an inch or so, but we awoke to see white streets, yards, and rooftops. However, the sky has cleared off the past hour or so, and the satellite image shows some clear air upstream of where we are (in the black circle):
That huge patch of white in the southeast central part of the state is the larger snowfield - in Fort Collins we were on the very northern fringe of the snowfall. Cindy reported to me on a walk up the local ridgetop here this morning before the sun came out that the snow ended just north of town, and didn't seem to even extend that far east of here either. The satellite seems to suggest that too. By now though, any snow here in the direct sun has melted.
One thing I still have a hard time understanding is why forecasters still think of "dynamics" and "Q-G omega" as somehow separate entities. They're the same freakin' thing! I may not be in meteorology anymore, but if there was one thing that stays with me, it's that. Ugh.
