NextGen™: Enhanced Forecasting for Advanced Decision Making (Premium Layer)

NextGen™ is Tomorrow.io’s advanced forecasting layer, designed to deliver improved accuracy, probability-based insight rules, and hyperlocal weather intelligence. This guide outlines the key features of NextGen™ and how to use them effectively.

🔒 This is a premium feature available by request. For access, please contact your Account Team or sales@tomorrow.io.

Accessing NextGen™

To toggle between Classic and NextGen™ views:

1. Locate the view toggle switch in your dashboard

2. Select NextGen™ to activate enhanced map layers, probability forecasts, and improved data visualizations

Key Features

Enhanced Map Visualizations

• Updated display layers with clearer probability overlays

• Improved interpretation of forecast uncertainty and likelihoods

Probability Forecasts

• Supports planning and risk management through probabilistic outlooks

Insight Rule Probability

View the likelihood that a defined Insight threshold will be met during the forecast period.

Probability is provided as additional context to help assess forecast confidence and support operational decision-making.

Note: Insights trigger when forecasted conditions meet the defined threshold. The probability shown provides additional context on how confident the forecast is that the threshold will be reached.

Supported Parameters

NextGen™ supports probability forecasts for:

• Temperature

• Dew Point Temperature

• Relative Humidity

• Wind Speed and Wind Gust

• Surface Visibility

• Surface Pressure

• Mean Sea Level Pressure

• Precipitation Rate

• Cloud Base

• Cloud Ceiling

• Cloud Cover

⚠️ C-BAM (Customizable Baseline for Atmospheric Modeling) is not currently supported in NextGen™ view. Switch to Classic view to access C-BAM data.

Accumulation Parameters

NextGen™ provides probabilistic accumulation forecasts to help assess how much precipitation may fall over a forecast period.

• Rain Accumulation
• Snow Accumulation
• Ice Accumulation
• Total Precipitation

Probability visualization is available in:

• Maps
• Trends
• Dashboard widgets
• Reports

Note: Accumulation parameters do not currently support Insight Rule Probability. If an Accumulation Insight is triggered, probability information is available only from the graph in the Investigate view.

For details about how NextGen precipitation accumulation is calculated and how it differs from Precipitation Intensity, see Accumulation Weather Parameters: Rain, Snow, Sleet.

Additional Capabilities

• Timeline & Trend Probability Spread: Visualize forecast probabilities across time for long-range operational planning

• Insight Rules Probability View: Evaluate the confidence that forecasted weather conditions will meet an Insight's configured threshold

• Insight Investigation: Dive into the data behind triggered insights to understand the full operational context

• Probability Visualizations: Available across Maps, Trends, Dashboard widgets, and Reports for supported parameters.

NextGen™ Unified Precipitation

Tomorrow.io’s Global Space Precipitation product powers Unified Precipitation (UP) with satellite-enhanced data.

Key improvements include:

• Improved Accuracy: Increases forecast accuracy by 5–10%, outperforming public datasets like IMERG-Early

• Broader Coverage: Adds real-time data in regions lacking radar (e.g., Western US)

• Higher Resolution: Hyperlocal forecasts at 5km spatial resolution

• Frequent Updates: Refreshed every 5 minutes to support rapid-response use cases

Integration Notes

If you're using CBAM:

• Switch to Classic View to access CBAM datasets

• Use the view toggle to move between Classic and NextGen™ modes based on data needs
