In the cooler months with unsettled weather I find it very useful to refer to good satellite images before my trips to DCHS. Here is the link to one site I use regularly:
http://wwwghcc.msfc.nasa.gov/GOES/
I mostly use the one titled " Pacific Ocean " and there are visible ( daylight hours ), infrared and water vapor versions. At this site you can animate ( choosing variable loop numbers ) and customize the images to your own preferences. Just click on an image and when the enlarged version comes up, make any desired changes then click animate. Its available 24/7 so no need to wait for weather reports from TV sources.
