AWIPS composite images of the 6.7\u00c2\u00b5m GOES-11 and 6.5\u00c2\u00b5m GOES-12 “water vapor” channels (above)<\/strong><\/em> show the eastward progression of synoptic-scale frontal systems across the US and Canada — as well as the westward motion of what could evolve into a subtropical disturbance in the eastern Gulf of Mexico — on 02 October 2007<\/strong><\/a>. Regions of greater middle-tropospheric moisture (blue to white enhancement)<\/em> and clouds (white to green enhancement)<\/em> are evident along and ahead of many of these fronts, while areas of subsidence and dry air (yellow enhancement)<\/em> are seen in the wake of some of the frontal boundaries.<\/p>\n

The CIMSS Regional Assimilation System (CRAS<\/strong><\/a>) numerical weather prediction model has the ability to output synthetic satellite imagery<\/em> — a “forecast” of what GOES imagery might look like in the near future. AWIPS images of CRAS predictions of the GOES water vapor channel imagery (below)<\/strong><\/em> show the forecast covering the 02-05 October 2007 period. The CRAS imagery indicated that the pattern of alternating moist and dry features (associated with subsequent frontal passages) would continue for the next 2-3 days, while the moisture associated with the Gulf of Mexico disturbance would eventually move inland across the western and central Gulf Coast states during the forecast period.<\/p>\n

\"AWIPS<\/a><\/p>\n

CIMSS has been generating CRAS water vapor<\/strong> and IR<\/strong> forecast imagery since the mid-1990s, and this forecast imagery has been made available to AWIPS (via LDM subscription) since August 2006. The CRAS model forecast imagery in AWIPS has been well-received so far, being mentioned in several Area Forecast Discussions<\/strong><\/a> issued by the National Weather Service office at Milwaukee\/Sullivan, Wisconsin.
