from a friend... i also use this same resource all day long. his description was excellent so i thought i'd share it..
Check this Url -- it updates every 15 minutes: http://wwwghcc.msfc.nasa.gov/GOES/goeseastconus.html
Click on the map -- right where you figure you are -- and it will give a
very detailed blow-up of the immediate area.
Better than sticking your head out of the window and looking at the sky!!
I use it all the time for planning work days here.
And yes -- saw that you got pounded by what I call "Boil-ups" -- cause you
see the clouds "boiling up" -- in graphic detail -- and just know that rain
is there big time!!
Does not work at night -- for then go to the infrared or the cloud ones.
Main menu is at: http://wwwghcc.msfc.nasa.gov/GOES/
Checking just now -- there is a boil-up lashing Belize City -- and maybe CC --
