Unfortunately we are no longer able to generate the temperature and precipitation maps with the method we have been using for the past several years. We are working on finding another way to produce these maps each day.

We usually post the maps sometime between 11am and noon Eastern Time when precipitation has occurred over approximately the previous 24 hours.
