I've noticed lately, especially in the past few years something somewhat interesting. And because I can be analytical and nerdy I tend to keep track of these dumb things.
When a system is headed our way, there seems to be a brief moment of rising pressure right before a storm approaches...What happens is the pressure will gradually drop as the storm is getting closer, but then in a small window of time it will actually start to rise before it drops again once it makes landfall. This is starring to happen with more frequently unless I haven't been paying attention in the past. And if this unusual could it be tied to global warming/climate change?

Re: Winter storms and barometric pressure(climate change?)
I'm no expert at pressure, but what I imagine happening is that the approaching system (an extratropical cyclone associated with a trough of lower pressures) nudges an area of higher pressures out ahead of it, mostly towards the south (where Los Angeles would be). This would lead to a brief moment of higher pressures. Once the system makes landfall, the lower pressures associated with the system move inland. That's just a guess on my part.
Anyhow, that would appear to be fairly typical behavior. I don't think there would be much of a connection to climate change.

Re: Winter storms and barometric pressure(climate change?)
Hey, thanks for responding! But exactly why does it nudge an area of higher pressures out ahead of it? Is it because the storm is just that strong that it's creating it's own turbulence around it?

Re: Winter storms and barometric pressure(climate change?)
Forgive me if this is the wrong board but this is my first time in the winter weather board but I did have a question I'm living in Oklahoma City and I was wondering does anybody have a forecast or an idea on whether Oklahoma City will get a couple of big snow storms and or ice storms this year
