Ever look at a single snow forecast and think, "But what are the actual odds?"

The Probabilistic Precipitation Portal is a resource to help you get ahead of the storm by moving beyond a single number to give you the full picture. www.wpc.ncep.noaa.gov/Prob_Precip/

The differences in type will likely be quite variable across the Eastern US this weekend. If it's going to be snow or freezing rain will have important consequences.

The latest Key Messages detail the latest information regarding the impending winter storm set to produce far-reaching impacts from the Southern Rockies to the Northeast. The top graphic displays the Probabilistic Winter Storm Severity Index which depicts the probabilities for experiencing at least Moderate Impacts. Moderate Impacts speak to potential for hazardous travel conditions and some infrastructure impacts. The bottom image shows, of those probabilistic areas, which winter weather hazard (snow or freezing rain) is the most likely hazard in that area.

High-Impact & Far-Reaching Winter Storm 
A significant, long-duration winter storm is threatening over 160 million Americans with widespread heavy snow, sleet, and freezing rain from the Southern Rockies to New England, lasting from Friday through Monday. Extremely cold air will follow, prolonging dangerous travel and infrastructure impacts into next week.

Widespread Heavy Snow
Heavy snow is likely across a broad region from the Southern Rockies and Plains through the Mid-Atlantic and into the Northeast. Snowfall totals exceeding 12 inches are likely across the Ohio Valley, Mid-Atlantic, and Northeast. Widespread travel disruptions are likely. 

Catastrophic Ice Accumulation
Widespread freezing rain and sleet are expected south of the primary snow axis, affecting parts of the Southern Plains, Lower Mississippi Valley, Tennessee Valley, the Southeast, and southern Virginia. Significant to locally catastrophic ice accumulations are likely, with the potential for long-duration power outages, extensive tree damage, and extremely dangerous or impassable travel conditions. 

Extended Impacts
In wake of the storm, communities from the Southern Plains to the Northeast will contend with bitterly cold temperatures and dangerously cold wind chills. This will prolong hazardous travel and infrastructure impacts into next week. Preparations should be completed as soon as possible, & forecasts closely monitored for updates.

Over 160 million people are under winter hazards associated with the impending major winter storm. Disruptive snowfall is likely from the Rockies to the Northeast, including dangerous ice from the ArkLaTex to the Mid-Atlantic. You can find a detailed forecast at weather.gov.

The Boston Globe Test:

This satirical front page imagined a Trump presidency in 2016. Critics (including Trump himself) dismissed it as "alarmist" and "propaganda" at the time.

Do these headlines feel normal today? Even...quaint?

If so: we have grown more accepting of what was once unthinkable.

Funding deal rejects Trump’s push for major science cuts
Congressional appropriators released a “minibus” of three bipartisan spending bills today that would pare back the budgets of some science agencies but largely reject Trump’s request for steep cuts. The minibus consists of the Commerce-Justice-Science, Energy and Water Development, and Interior-Environment bills, which cover a substantial portion of federal research funding for fiscal year 2026.
The package includes:
$24.4 billion for NASA, a 1.6% cut (including $7.25 billion for NASA Science, a 1.1% cut);
$8.75 billion for the National Science Foundation, a 3.4% cut;
$8.4 billion for the Department of Energy’s Office of Science, a 1.9% increase;
$6.17 billion for the National Oceanic and Atmospheric Administration, roughly flat funding;
$1.42 billion for the U.S. Geological Survey, a 2.0% cut; and
$1.18 billion to the National Institute of Standards and Technology, a 2.3% increase
