No foehn, but still 90°F temp swing this week.

[Let'sgoflying!]

We had M14F yesterday, and expect 78F on Tues. Same with ND; they had M45F and will get 50F this week.
(yes I know this weather event has nothing to do with adiabatic winds lol)

Weather whiplash expected for millions across US with some places seeing 90-degree temperature swing

After shivering through below-average temperatures this week, nearly 75% of all Americans will soon have a chance to warm up with above-average temperatures arriving next week.

I have no idea what any of that means. Hope it’s fun?

I don't think there's a foehn in Texas. You don't feel moody, do you?

It’s a roller coasters. Two weeks ago we had nearly 90 degrees, two days later we didn’t even reach 50 and then below freezing. I thought winter is over when i saw 89 two weeks ago but i sure was wrong lol.

I think you need mountains for a foehn. But either way I'm ready for warm weather (even though I have a big ski trip coming up). Mostly because I keep flying airplanes without heaters in 0F weather.

Made me Google.

I guess it is a thing, pertaining to mountain winds.

If it were clustered, it would be a cell foehn.

Get those engine and cabin heaters going. It’s going to be indoor-raining in the hangars for a few days until the surrounding solids warm up. I hate these big swings.

In Canada they call the Foehn (or actually spelled Föhn as its german) Chinook.

Not my picture, but seems accurate:

I have no idea what a foehn is and I’ve lived in quite a few states.

ETA: if someone OP said chinook wind, that, I’d understand. I’ll just assume the MnnF is related to max temp, but without the context if foehn being a weather condition/event, it’s senseless to me.

Foehn and Chinook are the same thing, just different name for it but same phenomenon.

that means the OAT, outside air temperature, is changing from minus 14 degrees to positive 78 degrees in a few days. That means a lot of snow melt, and muddy or flooding conditions.

It’s exactly the same, just different.

Here's a diagram of Foehn mechanisms. Either way, the outcome is dry air blowing over the mountains, warming as it descends, to make spectacular conditions in the plain below.

Also, a photo of Munich, where I once lived, during the Foehn. Photo views South, toward the Alps; Saharan wind blows northward over the Alps toward the city. It's warm and the air is extremely clear, without the haze that usually blocks views of the mountains. (Related weird fact: people complain of headaches induced by the Foehn).

Yesterday 3 of us flew to breakfast for the first time this year. Bob was getting his BFR done at the same time. When we got back there was 4 of us in my hangar for a BS session with 3 heaters running. I stuck around the hangar for 12 hours yesterday with heaters and fan running to keep it dry in there and to blow the heat down from the ceiling. It helps keep it from sweating in there. I will do more of the same today although I won't be there as long today. When it starts sweating I leave the fan on 24/7 which helps a lot.
I think I was the first one at the airport yesterday morning and maybe the last to leave? I have only flew 3 times in January and 3 times in February so far. It's been cold and snowy here like many places this winter. Glad it's almost over!
