Amazing animation of former Major Hurricane Sam transitioning into an extratropical cyclone over the North Atlantic Ocean. Atlantic basin hurricanes often transition into extratropical cyclones over this region.

GOES EAST GeoColor enhancement satellite imagery over Florida showing ‘Nestor’ becoming extratropical.

GOES EAST GeoColor enhancement satellite imagery over the continental U.S. Complex low pressure system organizing in the Gulf of Mexico while the intense low pressure impacts the northeast U.S.

GOES EAST GeoColor enhancement satellite imagery over the continental U.S. Moisture stream from the eastern Pacific Ocean across Texas and the Gulf Coast, hooking up with a frontal boundary just offshore the east coast.

GOES EAST GeoColor enhancement imagery over the continental U.S. Two major low pressure centers impacting different parts of the country.

GOES EAST GeoColor enhancement satellite imagery over the continental U.S. Multiple low pressure systems off the east while a winter storm stakes shape over the northern tier.

GOES EAST GeoColor enhancement satellite imagery over the continental U.S. Complex pattern across the eastern half of the U.S. and western Atlantic Ocean.

GOES EAST GeoColor satellite imagery over the continental U.S. Cold front moving down the eastern seaboard marked by a classic ‘cold air damming’ along the leeside of the Appalachians as well as lines of cold air stratocumulus clouds over the northern Atlantic.

GOES EAST GeoColor satellite imagery over Florida. Surface to mid level east to west oriented high pressure ridge axis has shifted slightly to the north and is now lying across the south central peninsula. In turn the deepest moisture has also shifted northward with drier air now over the southern half of the peninsula. This will lower the overall coverage of afternoon showers and thunderstorms over the southern half. A majority of the activity will be north of the I-4 corridor where again the deepest moisture now exists. Steering level winds will continue to direct this activity towards the northeast.

GOES EAST GeoColor satellite imagery over Florida. Once again ongoing numerous showers and thunderstorms over the west coast. Areas currently void of clouds will have the highest potential for new development of showers and thunderstorms as daytime heating occurs and the sea breezes develop by late morning and early afternoon. Strengthening steering levels wind will continue to push activity the northeast . Upper level winds will continue to push thunderstorm anvil clouds towards the south and southwest.
