Current Conditions, Hourly, and 7-Day NWS Forecasts
Get current conditions, a 12-hour hourly breakdown, or a 7-day extended forecast for any US location — plus SPC and WPC outlooks and an AI weather briefing.
Snowball wraps the National Weather Service forecast API into three focused commands: current observed conditions, an hour-by-hour look at the next 12 hours, and a full 7-day extended forecast. For big-picture outlooks and AI-generated summaries, /weather outlook and /weather briefing round out the toolkit.
All NWS-based commands — /weather current, /weather hourly, and /weather forecast — are limited to US locations. The National Weather Service does not provide data for international areas.
The current conditions command shows the latest observed weather from the nearest NWS reporting station to your location. Snowball displays everything the station is reporting, along with a link to the full forecast on xtremewx.com.
Type a city and state, or use Tab autocomplete to select from suggestions. Snowball finds the nearest observation station and returns its latest report.

The hourly command gives you an hour-by-hour breakdown of conditions for the next 12 hours. Each period includes temperature, feels-like temperature (wind chill when applicable), conditions, wind speed and direction, humidity, and precipitation chance.
Temperature — in °F, with a feels like value when wind chill applies
Conditions — short forecast description for that hour; if precipitation chance is 60% or higher and the condition doesn’t already indicate rain or snow, Snowball upgrades the label automatically (for example, to Rain Likely or Snow Likely)
Wind — speed and direction
Humidity — relative humidity
Precipitation chance — probability of precipitation as a percentage
The forecast command returns the NWS extended 7-day forecast for your location. Each forecast period — named by time of day and day of week, such as Tonight, Wednesday, or Wednesday Night — includes a detailed plain-language forecast from the National Weather Service.
Type a US city or state. Tab autocomplete is available.

The 7-day forecast is a great companion to /weather alerts — check the forecast first for context, then check alerts to see if any watches or warnings are in effect.
View convective outlooks from the Storm Prediction Center (SPC), excessive rainfall outlooks from the Weather Prediction Center (WPC), and long-range temperature and precipitation outlooks from the Climate Prediction Center (CPC). Choose from Day 1 through Day 8 severe weather outlooks, fire weather outlooks, and extended pattern forecasts. An SPC severe weather timing chart by city is also available.
/weather briefing
Get an AI-generated weather briefing for any US location. Snowball gathers current conditions, alerts, forecast data, and NWS forecast discussions, then produces a concise narrative briefing in either conversational or structured style. When precipitation is happening or imminent, the briefing includes a current radar image for analysis. Briefings include a disclaimer that AI-generated content can make mistakes.
