Precision Forecasting

Our forecasting model analyzes significantly more than surface temperature alone. We calculate precise Apparent Temperature (Feels Like) using humidity, wind speed, cloud cover, solar intensity, and dew point to reflect how weather truly feels at ground level. Hourly updates and trend tracking provide measurable thermal comfort analysis for each U.S. city.

  • Feels Like Modeling
  • Hourly Temperature Variations
  • Dew Point & Humidity Analysis
  • Cloud & Radiational Cooling Impact

Severe Alerts & Safety

Safety is our priority. We process official National Weather Service (NWS) API data to display active watches, warnings, and advisories by city and state. Each alert is time-sensitive and location-specific, helping users quickly understand current threats such as tornadoes, flash floods, severe thunderstorms, winter storms, and extreme heat events.

  • Active Watches & Warnings
  • Tornado & Flood Monitoring
  • Time-Stamped Official Updates
  • Live Severe Weather Alerts

Frost & Freeze Risk

Our advanced model evaluates frost probability using multi-layer temperature trends, dew point spread, humidity, wind speed, and radiational overnight cooling rates. This helps identify precise conditions favorable for surface frost formation and cold-ground impact on vegetation. Risk levels are monitored and updated hourly as atmospheric conditions evolve.

  • Overnight Frost Probability Modeling
  • Dew Point Spread Analysis
  • Wind-Adjusted Surface Cooling
  • Hourly Frost Risk Tracking

Air Quality & Health

Air quality data is summarized using the Air Quality Index (AQI) to reflect real-time pollution intensity across U.S. cities. Conditions are evaluated to identify cities with elevated particulate matter (PM2.5 and PM10) and other pollutant levels, helping protect sensitive groups and guide outdoor planning. Data is updated hourly to help you minimize exposure to harmful atmospheric pollutants.

  • Daily AQI Forecasts
  • Pollution Risk Classification
  • Health Impact Indicators
  • Pollution Level Warnings

Solar Intensity & Sky

Sky conditions are evaluated using the UV Index, cloud coverage, ceiling height, and visibility data. Hourly updates allow identification of peak UV intervals, shifting cloud patterns, and changing visibility ranges that may influence outdoor comfort and safety. This structured analysis supports more informed planning for travel, recreation, aviation, and extended time outdoors.

  • UV Index Measurement & Trends
  • Hourly UV Index Exposure
  • Cloud Ceiling & Visibility
  • Peak Exposure Time Detection

Precipitation & Hydrology

Precipitation forecasts include Probability of Precipitation (PoP), rainfall intensity signals, and snow accumulation estimates. Short-term hourly tracking combined with 7-day and 30-day outlooks highlights storm timing, accumulation risk, and potential travel impact. We track precipitation type changes and intensity trends to assess surface impact.

  • 7-Day & 30-Day Outlook Trends
  • Snowfall Depth Estimates
  • Rainfall Probability (%)
  • Hourly Intensity & Phase Tracking

Detailed daily and hourly forecasts, including today's weather, 7-day, 30-day forecasts, long-term monthly forecasts, and much more.

Our mission is to provide real-time weather updates for every U.S. city, with new locations added daily as we continually expand our coverage.
