Here is what we are paying attention to this evening and the next 48 hours from this afternoon’s NWS Forecast.
...There is a Slight Risk of excessive rainfall over Upper Great Lakes, Mid-Atlantic, and Eastern Gulf Coast through Monday morning... ...There is a Slight Risk of excessive rainfall from parts of the Upper Great Lakes and a second area over the northern Mid-Atlantic from Monday into Tuesday morning...
Continuation of the NWS Short Range Forecast (It is updated twice a day and these updates can be found here.
An upper-level low over the Midwest will move slowly northeastward to the Lower Great Lakes by Tuesday. Moisture streams northward across Florida, the Mid-Atlantic into the Upper Great Lakes will move off the East Coast by Monday. The system will produce rain and showers/thunderstorms over the eastern third of the country through Monday evening. Areas over the Great Lakes, Mid-Atlantic, and Eastern Gulf Coast will develop heavy rain. Therefore, the WPC has issued a Slight Risk of excessive rainfall over parts of three regions the Upper Great Lakes, the Mid-Atlantic, and the Eastern Gulf Coast through Monday morning. The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, and small streams the most vulnerable. On Monday, the threat of excessive rainfall continues over parts of the Upper Great Lakes and the northern Mid-Atlantic, with a Slight Risk through Tuesday morning. The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, and small streams the most vulnerable. Rain and showers/thunderstorms will continue over parts of the Northeast and Southeast through Tuesday. Meanwhile, moisture continues to linger over the southwest portion of the country as upper-level energy over the Pacific begins to move onshore and upper-level energy trapped under an upper-level ridge will aid in producing showers and thunderstorms over the region through Tuesday. Some of the storms may produce areas of heavy rain from Sunday into Monday. As a result, the WPC has targeted parts of Southern/Central California, the Great Basin, and Southwest for a Marginal Risk of excessive rainfall from Sunday into Tuesday morning. In addition, the associated heavy rain will create localized areas of flash flooding, affecting areas that experience rapid runoff with heavy rain. On Tuesday, as the upper-level energy moves farther inland, there will be a great lightly hood of producing heavy rain with the showers and thunderstorms. Therefore, the WPC has issued a Slight Risk of excessive rainfall over parts of the Great Basin on Tuesday. The associated heavy rain will create mainly localized areas of flash flooding, with urban areas, roads, and small streams the most vulnerable.

Some Intermediate-Term Outlooks
Links to “Outlook” maps and discussions for three time periods. Days 6 – 10, Days 8 – 14, and Weeks 3 and 4. 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.
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.
Right now you can find these maps here (We show them every Friday there but you can click above and find them).
World Forecast for Day 6 (Currently Set for Day 6 but the reader can change that)
World Weather Forecast produced by the Australian Bureau of Meteorology. Unfortunately, I do not know how to extract the control panel and embed it into my report so that you could use the tool within my report. But if you visit it Click Here and you will be able to use the tool to view temperature or many other things for THE WORLD. It can forecast out for a week. Pretty cool. Return to this report by using the “Back Arrow” usually found top left corner of your screen to the left of the URL Box. It may require hitting it a few times depending on how deep you are into the BOM tool. Below are the current worldwide precipitation and air pressure forecasts for six days out. They will not auto-update and right now are current for Day 6. If you want the forecast for a different day Click Here I will try to update this map each day but you have the link so you can access the dashboard and get a wide variety of forecasts.I mostly rely on the reader to interpret world maps. For this map, areas of expected precipitation for the date and time shown are clearly shown. The number of High-Pressure systems shown is called the Wave Number. Maybe I will discuss WN someday. But it shows how many Rossby Waves there are around the World. Sometimes they are hard to count. Counting Low-Pressure systems should provide the same WN. Rossby Waves are the way the temperature distribution of the Planet remains in balance. It is basically the science of fluid dynamics. It can be very helpful in predicting the movement of weather patterns. You can snip an area of interest and move it into MS Paint and enlarge it.
