00:00Wow, check this out.

00:03A lightning bolt was caught on video hitting the Space Needle in Seattle, Washington on

00:08Saturday.

00:09Spectacular.

00:10Wow.

00:11Beautiful.

00:12The atmosphere electrified.

00:16Of course, that's a very similar picture to maybe when we see the Empire State Building

00:21getting hit by lightning.

00:23You just don't see it every day and it's always quite fascinating and at least eye-catching

00:29every time it happens.

00:30Now we do have changes moving into the northwest and that's because we have an upper level

00:36low and we like to call an upper level low an area or a puddle of cool air aloft and

00:42that's exactly what is happening here in the west.

00:45Unseasonably cool air is going to be ushered in Thursday through Saturday.

00:49Dramatic changes.

00:51Highs are going to be changing from running on the warmer side to dropping about 10-20

00:56degrees below the historical averages.

00:59There's even going to be pockets of frost and we're talking high elevation snow through

01:03areas of the Cascades, parts of the northern or highest peaks of the mountain range in

01:09Idaho.

01:10That's where we could see some snow.

01:15Not consequential snow, but still snow nonetheless.

01:19As we head into Thursday, you'll see that it's going to be quite wet there in Portland

01:23and Medford.

01:24Highs remaining right in the 70s.

01:26Boise, you're at 95, still quite warm there.

01:29Las Vegas, you're at 104.

01:31Salt Lake City, 90.

01:32So you're hanging on to that warmth here for one more day, maybe one or two more days.

01:38You'll start to see those changes though.

01:39Boise, Thursday, you're at 95.

01:41Friday, 85.

01:43Saturday, you are at 67.

01:44Tracking big changes there, but also that fire threat remains through the start of the

01:49weekend.
