Your regular reminder that when folks say "its cold outside where I live, what happened to global warming?" that the world is big, and weather still exists.

The difference between cold rain, ice, and snow is very slim…
Winter weather is forecast to impact a large part of the country in the coming days. Will there be snow, ice, rain?
NWS Meteorologist Haley Thiem explains how the temperature of the air between the clouds and the ground determine the type of precipitation you get.

I am so incredibly tired of this “war” on climate and weather and research and science. If you don’t think these decisions are impacting you, I promise they are.
Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

I'm not sure most folks are aware of the immense magnitude of loss this would entail for the global weather and climate community, and beyond. NCAR has played a greater cumulative role in advancing weather prediction and atmospheric modeling than perhaps any other single entity in the world.

When you ask weather/climate people to name places that act as a hub of lifesaving research and innovation, Boulder CO would rise to top 2-3. NCAR Mesa Lab is the heartbeat of activities there. Can’t believe this is even on the table, let alone being lobbed out there like it’s already a certainty.

Before the 1990s, plane crashes caused by microbursts used to kill planeloads of people fairly regularly.
Dr. Ted Fujita and NCAR scientists figured out how to detect microbursts and warn pilots about them.
Since then? Zero airliner crashes from microbursts.

Climate denialism, empowered by nihilists and know-nothings, undermining science & destroying the evidence that they previously just rejected. Meanwhile, out here in WA, roads are sliding into rivers (an unprecedented weather event) b/c it’s too damn warm to be raining this hard for this long.

Bitter cold temperatures are forecast across the northern Plains to the Mid-South through the weekend. Well below normal temps combined with gusty winds will create dangerous wind chills.

Yearly pre-winter reminder…
Record cold and snow in one area/region does not dismiss or invalidate the reality of long-term climate change. www.climate.gov/news-feature...

Are record snowstorms proof that global warming isn’t happening?
The United States has plenty of warming wiggle room before it gets too warm to snow, and a wetter atmosphere may boost snow totals for some storms.

Continuing to try to modernize some graphics for the NWS! But also good thing to check on winterizing your home before the end of the weekend/early next week cold snap!

Hearing atmospheric river? Want to know what all that is about? Watch this video!
If you live in the West, you’re likely to see the words “atmospheric river” pop up in the forecast over the next several days.
This is not a new term; in fact it was coined in 1994!
But what is an atmospheric river, and what weather hazards can you expect? Meteorologist Haley Thiem explains.
