Frost and Freeze Warnings where growing season started
Cold snap in Western Europe too right now.
Right now it's exactly 0C over here. Plants and trees are in full bloom, the average low should be 7C or so.
The last time we hit 0C was March! Record low for May here is -2C, feels so good to get close. Today we also reached the lowest dewpoint of the year, -7C this afternoon.
Maybe it affects the stability of the atmosphere around Lexington.
So do you think it's directly correlated with instability? That would explain why the occasions it does happen are almost always with a storm that formed recently.
What about elevation changes leads to stabilization? I'm trying to envision what that physically does to the atmosphere. And I know that for example northern Alabama is just as hilly as here, although proximity to the Gulf might be the dominant factor there.

Wow! Interesting. Lets see who breaks out from this pattern first.

Since the vortex weakened and split in January we been getting these shots. IMO we would of had another crazy cold winter if it wasnt for El Nino. Now with Nino gone and Nina coming back, one wonders if this is the beginning theme heading into Fall and Winter again.

TWC had an interesting segment. They mentioned that inner citys affect lightning and thunderstorms with the buildings and the extra heat they produce. My phone rang and I missed the rest.
Since ice particles in the air creates positive and negative charges, maybe there is less ice above you? So maybe there is not enough charged particles to seperate and trigger a spark (lightning)?

I don't think it's directly correlated. I think there are some areas where lightning is more frequent at higher elevations.
Maybe Lexington has less instability since it's on the northern slope which blocks some of the southerly winds.

It's like a broken record, warm in the west cold in the east. How long is it possible for this to go on?! The cold era of the late 70s only lasted 4 years, it can't possibly last more than that, can it?

Just to be sure, you know I'm referring to specifically cloud-to-ground lightning? Lexington gets a good amount of lightning overall.

I hope your not talking about lightning bolts hitting the ground. CLG is not 'that' common and sometimes it happens and you dont see the leader hit the ground anywhere. And I doubt you only see cloud to cloud lightning which is the more common lightning. Perhaps you do get CLG but just dont see the bolt??
