Just “warmer” compared to the cold air coming in.

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.

Especially considering La Niña…

🚨🔥 Warmest Christmas on record for the Contiguous U.S.! The average high of 57.9F and the average low of 36.6F each broke the Christmas record by a full 3F. 🔥🚨

It’s me. I’m a meteorologist, I work with the NWS.

🎵 Will it snow, will it snow, will it snow?

Have you been dreaming of a white Christmas this year? Above normal temperatures and rain over the next week could melt those dreams away...

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.

Some things that were lost that used to be part of OAR
Climate.gov went dark at the end of June 2025. So we missed: ENSO blogs, Polar Vortex blogs, Monthly Climate Outlooks, State of the Climate highlights, Arctic/Antarctic Sea Ice posts, Event Tracker articles, a Winter Outlook, and Global Climate Summaries.
Let's bring it back. #ClimateForUs

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.

The sun is bringing the beauty both night and day this week with overnight Aurora's followed by a spectacular sunrise with morning's first light splashing on the underside of a cloud deck over Colorado.
