Not a lot of news this weekend. Today has been a day to keep things as simple as possible. Work has been fun, but ridiculously busy. We are now doing an amount of work that makes last spring's records look paltry. The main reason I love doing what I do is that it's so cool to watch small businesses get bigger, and it's even cooler when it's your own.

So, it was a good day to keep tabs on the upper low and snow in Boston.

Yes, it snowed in Boston for much of the day. Accumulations were light, but snow anywhere along the coast from Boston south, this early, is noteworthy. What happened?

The key this morning was shown by 8am upper air map. It showed a self-contained cold core of air at the 850 millibar level (that's about 5000 feet), the height at or above which precipitation forms. Over New York City, the 850 mb temperature was -8 C (or about 18 F). Northeast of Quebec City, much further north, the 850 mb temperature was 2 C (or about 35 F). This cold core, centered over southern New York and New England, moved east and intersected with an ocean storm. It all came together just right for snow in Boston. Around 10:30 a.m., I noticed some very light snow mixing with the light rain here, but that lasted only a few minutes.

Now that baseball season has ended, it's nice that the weather is starting to get interesting.
