Most Likely Precipitation (50th Percentile) [mm]
This map shows the most likely 12-hour accumulated Precipitation forecast (50th percentile) in millimeters (mm) from the Canadian Regional Ensemble Prediction System.
Data updates 4 times daily: at approximately midnight, 6 a.m., noon, and 6 p.m. UTC. This translates to 8 p.m., 2 a.m., 8 a.m., and 2 p.m. Eastern Time, and 7 p.m., 1 a.m., 7 a.m., and 1 p.m. Central Time.
Possible Least Precipitation (10th Percentile) [mm]
This map shows the possible least 12-hour accumulated Precipitation (10th percentile) in millimeters (mm) forecast from the Canadian Regional Ensemble Prediction System.
Data updates 4 times daily: at approximately midnight, 6 a.m., noon, and 6 p.m. UTC. This translates to 8 p.m., 2 a.m., 8 a.m., and 2 p.m. Eastern Time, and 7 p.m., 1 a.m., 7 a.m., and 1 p.m. Central Time.
Possible Most Precipitation (90th Percentile) [mm]
This map shows the possible highest 12-hour accumulated Precipitation (90th percentile) in millimeters (mm) forecast from the Canadian Regional Ensemble Prediction System.
Data updates 4 times daily: at approximately midnight, 6 a.m., noon, and 6 p.m. UTC. This translates to 8 p.m., 2 a.m., 8 a.m., and 2 p.m. Eastern Time, and 7 p.m., 1 a.m., 7 a.m., and 1 p.m. Central Time.
Probability of Exceeding 2.5 mm Precipitation [%]
This map shows the probability (in percent) that the 12-hour accumulated Precipitation will exceed 2.5 mm (~⅒”), based on the Canadian Regional Ensemble Prediction System.
Data updates 4 times daily: at approximately midnight, 6 a.m., noon, and 6 p.m. UTC. This translates to 8 p.m., 2 a.m., 8 a.m., and 2 p.m. Eastern Time, and 7 p.m., 1 a.m., 7 a.m., and 1 p.m. Central Time.
Probability of Exceeding 5 mm Precipitation [%]
This map shows the probability (in percent) that the 12-hour accumulated Precipitation will exceed 5 mm (~²⁄₁₀”), based on the Canadian Regional Ensemble Prediction System.
Data updates 4 times daily: at approximately midnight, 6 a.m., noon, and 6 p.m. UTC. This translates to 8 p.m., 2 a.m., 8 a.m., and 2 p.m. Eastern Time, and 7 p.m., 1 a.m., 7 a.m., and 1 p.m. Central Time.
Probability of Exceeding 10 mm Precipitation [%]
This map shows the probability (in percent) that the 12-hour accumulated Precipitation will exceed 10 mm (~⁴⁄₁₀”), based on the Canadian Regional Ensemble Prediction System.
Data updates 4 times daily: at approximately midnight, 6 a.m., noon, and 6 p.m. UTC. This translates to 8 p.m., 2 a.m., 8 a.m., and 2 p.m. Eastern Time, and 7 p.m., 1 a.m., 7 a.m., and 1 p.m. Central Time.
Probability of Exceeding 25 mm Precipitation [%]
