Been looking at random snowstorms that may have hit my new area before I lived here. Especially ones that I did not share any part of at my former abodes. Looks like the infamous December bomb that brought Chicago gravity wave intense snow back in 1987 hit Harrison pretty hard as well. This SLP intensified rapidly to 980 mb as it closed-off over SMI. Amazing there was places in OK with over 12" depth from this one. I'd take another of these any time.

Very nice day today with a decent north wind blowing much of day. 68/47 IMBY.

Just saw this one even though it was posted quite a while ago. In a situation like the valleys of CA west of the Sierras are in, the cold air (which mainly slides down east of the mountains) creates higher pressure east of the mountains which forces the air to flow westward toward the valleys and the ocean. When the air is forced over the mountains it compresses the air that is in place west of the mountains which warms and dries the air. Even though the air begins cold it ends up warm at the surface in the valleys west of the mountains. If the air mass east of the mountains is really cold then the valleys west of the mountains can also end up somewhat cold. Even up in WA State, which is where I live, this same thing happens although the air is often a lot colder to begin with than what you experience down there. In spite of that there is a still a lot warming as the air compresses west of the mountains.

Gorgeous early fall day. Working out in it the sun angles were EXTREMELY noticeable. 12/1/24 00z in 1,802 hours and 15 minutes.

Huh that narrative fell apart quickly.
