GOES-12 visible (daytime)<\/em> and 3.9 \u00c2\u00b5m shortwave IR (night-time)<\/em> images (above)<\/strong><\/em> showed a distinct swirl of clouds drifting northward across the Gulf of Mexico on 13 November<\/a> – 14 November 2008<\/a><\/strong>. This cloud swirl was actually the remnants of Hurricane Paloma<\/strong><\/a>, which had intensified to a Category 4 hurricane<\/strong><\/a> and made landfall over Cuba on 08 November. Note that there were a few weak convective bursts forming near the center of the swirl, but these were fairly short-lived.<\/p>\n

AWIPS images of the 1-km resolution MODIS visible, 11.0 \u00c2\u00b5m IR window, and 3.7 \u00c2\u00b5m shortwave IR images (below)<\/strong><\/em> indicated that the swirl was comprised of primarily low-level clouds at 18:54 UTC, with IR brightness temperatures considerably warmer\u00c2\u00a0 than -20\u00c2\u00ba C — in fact, the MODIS Cloud Top Temperature<\/strong><\/a> product displayed values that were generally in the 0\u00c2\u00ba C to +10\u00c2\u00ba C range.<\/p>\n

The MIMIC Total Precipitable Water<\/a><\/strong> product (below)<\/strong><\/em> showed that the remnants of Paloma (which initially had drifted back southwestward over Cuba on 12 November)<\/em> were embedded within a plume of higher precipitable water (30-45 mm, or 1.2-1.8 inches)<\/em> as it moved northward across the eastern Gulf of Mexico.<\/p>\n

As the remnants of Paloma reached the coast of the Florida panhandle on the morning of 14 November, explosive convective development was seen. This convection actually displayed a well-defined “enhanced-v”<\/em> storm top signature on the GOES-12 10.7 \u00c2\u00b5m IR imagery (below)<\/strong><\/em>. Some back-building of the convection was also evident on the IR imagery — this convection produced a swath of heavy rainfall and flash flooding across parts of the Florida panhandle region, with a report of 9.25 inches<\/strong> of rain at Bloxham (located to the southwest of Tallahassee),<\/em> and 2.61 inches<\/strong> falling at Tallahassee (setting a new rainfall record for the date)<\/em>. Radar-estimated storm total precipitation<\/strong><\/a> exceeded 14 inches.<\/p>\n

A comparison of 1-km resolution NOAA-18 and 4-km resolution GOES-12 IR images (below)<\/strong><\/em> demonstrated the superior enhanced-v detection capability of higher spatial resolution data. The enhanced-v “delta-t” value (the difference between the coldest overshooting top and the warmest portion of the downstream warm wake)<\/em> was an impressive 22.8\u00c2\u00ba C<\/strong>, which would be a large delta-t value for a tornado or hail-producing supercell over the Great Plains region! This convection was also producing a good deal of cloud to ground lightning<\/strong><\/a>, as was noted on the early morning NWS Tallahassee Area Forecast Discussion:<\/p>\n

…SCATTERED SHOWERS AND THUNDERSTORMS HAVE BEEN DEVELOPING OVER OUR AREA…WITH A FEW OF THESE STORMS ALREADY EXHIBITING MARGINAL ROTATING UPDRAFTS AND IMPRESSIVE CLOUD TO GROUND LIGHTNING. THE LATEST RUC INDICATES MUCAPE FROM 350 J\/KG OVER CENTRAL GA TO 1500 J\/KG ALONG THE FL GULF COAST. THIS IS RATHER IMPRESSIVE FOR THIS TIME OF YEAR…<\/p><\/blockquote>\n
