Weather ''Baked Alaska'': 90-96° temps shatter all-time records

By Scott Sistek Published: Jun 17, 2013 at 11:00 PM PDT Last Updated: Jun 18, 2013 at 10:51 AM PDT

Many people head to Alaska to visit the snow-capped mountains and awe-inspiring glaciers.

Monday, sitting on a glacier might not have been a bad idea.

A major ridge of high pressure brought intense heat to south-central Alaska with four towns experiencing heat never before felt in their record-keeping history.

Weather For 2nd month in a row, Seattle sets obscure all-time weather record

By Scott Sistek Published: Jun 17, 2013 at 11:10 AM PDT

For the second month in a row, Seattle has managed to set an obscure, but all-time weather record. And once again, it goes with the prevailing theme of super nice weather to begin a month, then paying for it as the month draws to a close.

In May, it was the first 11 days with zero rain and being warmer than 65 degrees.

This month, the first 14 days of June have had high temperatures of 68 degrees or warmer -- the first time that's ever happened in the 68 years of Sea-Tac Airport records, according to meteorologist Jason Phelps. That record has since been stretched to 16 days with a chance of the 17th coming Monday.

Weather Photos: Rainbow halos galore around the Puget Sound region Saturday (Photo Gallery)

You've all seen rainbows on those days where it's raining and the sun's out at the same time. But what about those times when you see a rainbow-like halo around the sun or moon?

It's the same physics, really. The halos (or, sometimes known as "sundogs" around the sun) are usually seen when there are high cirrus clouds overhead.

Those clouds are made of tiny ice crystals, which will refract the sunlight much like a prism will and voila! You have a rainbow halo around the sun.

Weather Northern Lights video shows Seattle is perhaps too bright at night?

By Scott Sistek Published: Jun 14, 2013 at 6:44 AM PDT Last Updated: Jun 14, 2013 at 11:18 AM PDT

Don Jensen had a neat idea when the Northern Lights came out in early June: Use Mt. Rainier as a tall dividing line to showcase how the city lights of the Seattle metro area can interfere with viewing the aurora.

But more than that, Jensen wondered if our city really needs to be so bright.

His 17-second video was captured the night of June 6 into the morning of June 7 and shows roughly four hours of night activity over our tallest volcano.
