Wednesday's WeatherCam


The above WeatherCam image is for Wed Feb 18, 2008. The time in UTC is displayed at the top right of the animation. A larger animation can be viewed at the LSC Meteorology site webcam archive. It documents a weak storm system moving into the NEK and most of New England from the southwest. The camera faces eastward from the college campus towards Burke Mountain. Clouds moving into the page therefore mover from west to east, and those moving from right to left move form south to north.

The day begins with clear conditions and occasional high level cloud moving across the region from the northwest. Around 11 AM (16 Z) a mid level deck of cloud (at about 5 km or 15 000 feet)moves in from the west with the jet stream. Around 18Z. a lower, thicker deck of clouds moves in rapidly from the south. By sunset around 5 PM (22Z), this deck has lowered to the top of Burke Mountain (about 4000 ft). Snow begins to fall and obstruct the view of the mountain in the final few frames of the animation.
