I'm not sure how to interpret the wind directions posted on the website. For example, does "Wind: S" mean the wind is blowing from the south, or to the south (i.e., from the north)? Brett

MIKE MOSS SAYS:     Brett,    By general agreement in the meteorological and aviation communities, the term "wind direction" is defined as the compass heading FROM which the wind is blowing. This is in contrast to the term "bearing," which indicates the direction toward which an object is moving. The result is that a north wind, for example, would cause a balloon to follow a southerly bearing. So, when you see something in our forecast like E/SE 5-10 mph, we're saying the wind is likely to blow from the east and southeast at around 5-10 mph.
