An AWIPS image of the MODIS 11.0-3.7 \u00c2\u00b5m IR brightness temperature difference “fog\/stratus product” (above)<\/strong><\/em> indicated that fog\/stratus features were in place across parts of the Southeast US, as well as along and just off the coast of Georgia, South Carolina, and North Carolina at 07:33 UTC or 2:33 AM local time on 29 January 2013<\/strong><\/a>.<\/p>\n

The GOES-13 Instrument Flight Rules (IFR) Probability product (below; click image to play animation)<\/strong><\/em> showed very high probabilities of IFR conditions at many inland locations, but also suggested that the fog\/stratus features were extending much farther off the coast.<\/p>\n

During the daylight hours, McIDAS images of GOES-13 0.63 \u00c2\u00b5m visible channel data (below; click image to play animation)<\/strong><\/em> showed that the near-shore sea fog did indeed persist for much of the day, especially off much of the Georgia and South Carolina coastlines.<\/p>\n
