Weather Observations

Weather-related pages and data are available here.

Gridded Weather Data

View daily maps and access single point or whole-grid data series for weather parameters including daily min, max, and mean temperatures, dewpoints, vapor pressures, and humidity.


Gridded Daily Precipitation Data

View daily maps and access single point or whole-grid data series for daily precipitation totals. Data is derived from NOAA-generated datasets.


HYD Reports

We offer online access to NWS HYD reports -- daily weather summaries of temperature and precipitation by volunteer observers -- for hundreds of locations throughout Wisconsin going back to 1995. The reports are text files, one per day.


Automated Weather Observation Network

From 1985-2017, we maintained automated weather stations at the Hancock and Arlington Ag Research stations. (Others were also operated in the 1980s-1990s.) They made hourly observations and daily averages for temperature, humidity, wind speed and direction, solar radiation, and soil temperature. Stations were discontinued in 2017. Since then data from Arlington and Hancock can be accessed via the Michigan State University Enviroweather Service.
