Morning weather picture from 22,500 miles up


I found this morning's visible satellite imagery to be rather interesting, so I thought I'd share.

The remnants of one system and the early signs of a second are shown on this Mid-South view. Note the low level moisture, in the form of stratus clouds, in the wake of yesterday's weather system over the Lower Mississippi Valley, Tennessee Valley, and interior southeast. As we know, the clouds broke up over the city this morning and you can clearly see at 9:15am that the back edge was right along the river and just to our north. Within an hour of that image, they began dissipating over Shelby County.

You can also see very high wispy clouds starting to appear over the southern Plains as the next weather maker, which will bring us a round of thunderstorms Saturday night, organizes to our west.

The thing that caught my eye quickest though was the snake-like white traces across northwest Arkansas and eastern Oklahoma. That is radiation fog that formed in the valleys and river bottoms. As would be expected, the fog had dissipated by the satellite image taken about an hour later (now shown). ((Thanks to the reader who corrected me on this being fog and not ridge-top snow. Should have known that...))

That was not snow in NW AR, but rather fog in the river bottoms. All snow had been COMPLETELY melted a few days ago.

Ohh, you're right!! Wow, thanks! Never occurred to me, but that's a great example of fog radiation fog then too! Thanks again!
