The GOES-13 satellite had been placed into Rapid Scan Operations (RSO) mode, providing images as frequently as every 5-10 minutes. With high pressure located to the north over western Quebec, the surface winds were generally light from the east across the region — and with a stable air mass in place, no precipitation was reported at any of the observing stations as the mesolow approached the coast and moved inland.<\/p>\n

The structure of the mesoscale vortex could also be seen using 250-meter resolution Terra and Aqua MODIS true color images from the SSEC MODIS Today<\/a><\/strong> site (below)<\/em><\/strong>.<\/p>\n
