<p>Live radar from F5Weather</a></div>

Our radar is based off of US NEXRAD and Canadian weather radar sites through the quality controlled MRMS system. It compiles various sources for radar data and filters out erroneous returns such as sun spikes and ground clutter. We then colorize the precipitation based on our methods for determining precipitation type. Rain is in shades of green, mixed precipitation and freezing rain in shades of pink and snow is in shades of blue.

<p>Live satellite from F5Weather</a></div>

Our satellite is from the GOES-16. It is color enhanced by using a geocolor terrain background during the day and black marble city lights at night. The daytime satellite data is Visible satellite imagery, and nighttime uses Infrared bands. The bluish clouds are fog and low cloud. The whiteest clouds are the coldest, highest cloud tops.

Current surface weather map around Brown County, WI

This surface map is from the HRRR computer model. It is a 1-hour forecast, updated hourly, which is a good estimate of the current surface conditions. This map shows the current high and low pressure centers, pressure isobar contours, wind streamlines and thickness contours. It also shows the currently depicted preciptiation estimates, although this should not be a substitute for actual live radar. The purple dashed contour is the 5400m thickness line, which is often a good proxy for the rain/snow line.

<p>Hurricane Tracking from F5Weather</a></div>

Our hurricane tracking map monitors for any current or forecast tropical disturbances in the Atlantic. (See our Pacific Hurricane Tracker) Various hurricane models will draw a 'spaghetti plot' in the Atlantic Basin when a disturbance is forecast or exists, showing the system's forecast track. Once a storm has developed, the National Hurricane Center will forecast their official track. This will show up on the map along with the storm's current intensity, track and name. We will also plot some of the storm's vitals and of course the spaghetti plots from the models along with the NHC forecast track will give you an idea of where it's heading, and its forecast intensity with time.

Climate Change
The climate of Green Bay is changing, as it is in many parts of the world. The average annual temperature has increased by about 2°F (1.1°C) since the late 19th century. This warming trend is expected to continue in the future, with the average annual temperature projected to increase by another 2-4°F (1.1-2.2°C) by the end of the century.

The increase in temperature is leading to a number of changes in the climate of Green Bay. The growing season is getting longer, and the number of days with extreme heat is increasing. The winters are also becoming shorter and milder, and the amount of snowfall is decreasing.

These changes are having a significant impact on the environment and the people of Green Bay. The longer growing season is allowing farmers to grow new crops, but the increase in extreme heat is also causing problems for crops and livestock. The shorter and milder winters are making it more difficult for winter sports enthusiasts to enjoy their favorite activities.

The changing climate is also having a negative impact on the Great Lakes. The lakes are warming, and the ice cover is decreasing. This is leading to changes in the ecosystem of the lakes, and it is also making it more difficult for ships to navigate the lakes.

The people of Green Bay are taking steps to address the challenges of climate change. The city has adopted a number of policies to reduce greenhouse gas emissions, and it is working to promote renewable energy and energy efficiency. The city is also working to adapt to the changes that are already happening, such as by building seawalls to protect against flooding.
