Station Information

Current Status

Station Equipment

We operate a Davis Instruments Vantage Vue wireless weather station.  The sensor suite is mounted in a location that provides the most accurate data, within the limitations of property characteristics. Data is transmitted from the sensor suite to the weather console every 2.5 seconds. We connect the Vantage Vue equipment to the internet by way of a personal computer and provide regular weather updates on this website.  We also provide our data to several other weather services, media outlets, and private entities.

Data Quality and Accuracy

The positioning and calibration of the weather station sensors has been carefully considered to maximize accuracy of the readings. We participate in the Citizen Weather Observer Program (CWOP) to help make sure our data is accurate.

CWOP checks weather stations’ data against one another to compare quality. We are automatically notified if any irregularities are detected and can take action to improve our data quality.

Data Distribution

Our data is distributed to several weather networks:



Weather Underground is a commercial weather service that provides real-time weather information via the Internet. View our Weather Underground data.



The Citizen Weather Observer Program (CWOP) allows users with computerized weather stations to send their information via a Web site to be included into the United States Mesonet. This data is then used by the Rapid Update Cycle (RUC) forecast model to produce short term forecasts (3 to 12 hours into the future) of conditions across the United States’ lower 48 states.

AWEKAS is an automatic weather mapping system for data provided by private weather stations around the world. It was started in Austria and has been in operation since 2004. It has over 2,000 weather stations participating around the world, providing data in German, Dutch, English, French and Italian. The initials stand for “Automatisches WEtterKArten System”.

The National Weather Service is tasked with providing weather, hydrologic, and climate forecasts and warnings for the United States, its territories, adjacent waters and ocean areas, for the protection of life and property and the enhancement of the national economy. This is done through a collection of national and regional centers, and 122 local weather forecast offices (WFOs). Our data is included in the Milwaukee/Sullivan Wisconsin Daily Hydrometeorological Product. Our ID is WMW23, Southeast Wisconsin, Milwaukee County, Greendale.


The Met Office is the UK’s National Weather Service. The Met Office is a world leader in providing weather and climate services, employing more than 1,800 at 60 locations throughout the world. They are recognized as one of the world’s most accurate forecasters, using more than 10 million weather observations a day, an advanced atmospheric model and a high performance supercomputer to create 3,000 tailored forecasts and briefings a day. You can see our observations at the Met Office Greendale Weather page.



WeatherBug provides data from a large global network to over 22 million online users every month. View our weather data at WeatherBug.





Weathercloud is a weather social network with actual live data sharing capabilities. Anyone with a passion for weather can follow devices from other people around the world. View our data on delivers site-specific forecasts for 60,000 sites in the U.S. and around the globe.  View our data at





SKYWARN® storm spotters are part of the ranks of citizens who form the Nation’s first line of defense against severe weather. To obtain critical weather information, NOAA’s National Weather Service (NWS), part of the U.S. Department of Commerce, established SKYWARN® with partner organizations. SKYWARN® is a volunteer program with nearly 290,000 trained severe weather spotters. These volunteers help keep their local communities safe by providing timely and accurate reports of severe weather to the National Weather Service. For information on becoming a trained spotter, contact the Milwaukee/Sullivan NWS or Milwaukee Area Skywarn Association (MASA).
