There is no front map available with Windy. Look the post here with explanation and alternative option : https://community.windy.com/topic/13381/fronts?_=1602142560863
You can also check weather institute website, they always publish front map like here as an example the MET office front map : https://www.metoffice.gov.uk/weather/maps-and-charts/surface-pressure
