Explain how and why the demarcation formed.

Picture is visible moisture satellite image taken 10OCT 2009 1930Z.

 

[tonycondon]

it would be my WAG that the demarcation line on the CA coast is probably fog that is forming over the very moist pacific ocean and not forming over the not so moist land.

 

[Richard]

Where? Along the western edge of the clouds through Colorado, NM and Texas?

Yes, and extending up towards Canada.

 

[TangoWhiskey]

Yes, and extending up towards Canada.

You mean right where the Rocky Mountain range runs?

lol

Well, I meant this as a sort of game. I knew it, I just wanted to present it for other pilots. Especially since it seems so many pilots avoid learning about the weather.

F'rinstance, when looking at a sat image how many would think of the underlying terrain, not necessarily mountainous terrain either.

We can always learn more.

Good work, Troy.

Now about that hole down in your area. What caused that?

 

[Richard]

Okay. That is referred to as upslope stratus.

Scott, as always, your input is much appreciated. Thank you.

Classic low centered over the great lakes with a trailing cold front, dry slot behind the moisture trail in from the gulf due to the lack of dewpoint activity in the slot, drawing gulf moisture up and to the northeast along and ahead of the front. Absolutely coastal fog off the west coast, and of course, the impact of the mountains creating lift and drying out the airmass from the west and downslope channeling the focus of the frontal activity to the east. Bet if you looked at the TAFS, FA's and WIND charts for the regions, you could see this phenomenon by looking at those data
Can winter be far behind?

Can winter be far behind?

Winter was already here in Denver when that picture was taken.

I hear ya! Cancelling a baseball playoff game for snow???? sheesh /// How about that domed stadium in the Mile High?

 

[TangoWhiskey]

Good work, Troy.

Now about that hole down in your area. What caused that?

Air spilling down off the high plains of west Texas.

It's either that, or Louisiana sucks.
