The heat dome that's been shattering

March temperature records in the Southwest

is going to linger and Seth Bornstein reports

it's spreading into the Central US.

And in size, it's getting to be one of the biggest

in US history.

Rivaling the 1930s dust bowl, it's a heat dome.

Like I have lid on a pot.

It's trapping the hot, stagnant air.

And this high pressure is stuck in itself

because the jet stream, which moves weather systems

from west to east, it's pretty close to stuck.

On the western end, if you follow the jet stream

a little further west to Hawaii,

you have storm after storm dumping,

inches feet of rain on Hawaiian,

something called a cone of low.

That's all connected.

That low pressure, that stormy system is stuck there.

It may not be until April until we see

this stuck pattern move on a little.

That's AP science writer Seth Bornstein.
