Days 6 – 10 Outlook
An outlook differs from a forecast based on how NOAA uses these terms in that an “outlook” presents information from deviation from normal and the likelihood of these deviations.
HAZARDS OUTLOOKS (I update these graphics every two days – but the reader can get an update if they want but the situation usually does not change that quickly)
Click here for the latest complete Day 3 -7 Hazards forecast which updates only on weekdays. Once a week probably Monday or Tuesday I will update the images. I provided the link for readers to get daily updates on weekdays. Use your own judgment to decide if you need to update these images.
Worldwide Weather (The U.S. is part of the World so the U.S. forecast is included in these maps)
Below maps are the short-term forecast for precipitation and 10-day forecast for temperature and precipitation. I update the Day 1 Forecast daily and the ten-day forecasts every two days. A ten-day forecast is not likely to change much in 24 hours. But if you are looking at an out-of-date version of this article the current forecast maps can be obtained HERE.
Worldwide Tropical Forecast
(This graphic updates on Tuesdays) If it has not been updated, you can get the update by clicking here This is a new approach and covers weeks 2 and 3 not weeks 1 and 2. It has more information but I am having trouble getting used to it. As usual, it comes with a discussion which is below

Links to “Outlook” maps and discussions for Two time periods. Days 8 – 14, and Weeks 3 and 4.
You have to click on the links because they do not update automatically and I do not want to have stale images in the article. But it is not difficult to click on a link and you get a large image plus a discussion. On Fridays in a separate article, we will show the images and provide a link in this article that article. But remember what you will see is the images as of Friday. But here you can get the current images simply by clicking on them. Then hit the return arrow at the upper left of your screen to return to the article. You will not find this information easily anywhere else.
