(Click and drag the moving slider button to manually roll the loop forward or reverse)

These visible images are from the GOES-10 Science and Operations Test. During this 3-hour loop, images at 5-15 minute intervals show an undular bore ahead of the leading edge of an advancing cold front. Surface wind barbs (blue) show that the winds change from southeasterly at 5-10 knots ahead of the feature to northwesterly at 10-30 knots as the it passes through the extreme southern counties of Texas and adjacent parts of northeastern Mexico.

Several shallow gravity waves can also be seen propagating northeastward through the stratocumulus clouds over the western Gulf of Mexico.
