Pepperridgenorthvalley.com is a proud member of the Citizen Weather Observer Program (CWOP). The above charts represent data reported to CWOP for North Phoenix, AZ (C3794 actuals in blue) with the predicted data based on surrounding stations (C3794 Analysis in red).

Data Quality:
The MADIS value represents the percentage of observations that have successfully passed the MADIS QC checks. If the Madis rating is within the acceptable limits, a green check will appear. Otherwise, a red x-mark will appear indicating that the data has not passed quality control.

Errors
If the above errors are POSITIVE, this means that the analysis variable is HIGHER than the reported variable. This means that the sensor is reading a variable lower than expected. If the above errors are NEGATIVE, this means that the analysis variable is LOWER than the reported variable. This means that the sensor is reading a variable higher than expected.

CWOP:
The Citizen Weather Observer Program (CWOP) is a private-public partnership with the National Oceanic & Atmospheric Administration. Its three main goals: 1) to collect weather data contributed by citizens; 2) to make these data available for weather services; and 3) to provide feedback to the data contributors so that they have the tools to check and improve their data quality.

Many thanks go to Phillip Gladstone at CWOP for his dedication to providing the needed accuracy and quality checks for the amateur weather observer.

 Pepper Ridge North Valley Random Weather Facts

DEW POINT
Dew point is the temperature to which air must be cooled for saturation (100% relative humidity) to occur. The dew point is an important measurement used to predict the formation of dew, frost, and fog. If dew point and temperature are close together in the late afternoon when the air begins to turn colder, fog is likely during the night. Dew point is also a good indicator of the air's actual water vapor content, unlike relative humidity, which takes the air's temperature into account. High dew point indicates high vapor content; low dew point indicates low vapor content. In addition a high dew point indicates a better chance of rain and severe thunderstorms. You can even use dew point to predict the minimum overnight temperature. Provided no fronts or other weather pattern changes are expected overnight, the afternoon's dew point gives you an idea of what minimum temperature to expect overnight.
