Here is what we are paying attention to in the next 48 to 72 hours. This article also includes World weather forecasts.

It also includes links for longer-term outlooks and sometimes we show the maps that one finds if one clicks on those links. But we can not update all of those maps each day so look at the date and the duration of the period of time involved. If you want a more up-to-date map, click on the provided link which may be located in a table of links. NOAA makes it difficult for us to have maps that auto-update. We are trying to make it convenient for readers but NOAA wants us to steer traffic to a large number of their websites which would make it very difficult for readers.

We start with the U.S. Information.
