Short Term and Intermediate-Term Weather Outlooks for the U.S. and a Six-Day Forecast for the World: posted September 14, 2023 – Hurricane Lee is Still a Factor

Here is what we are paying attention to in the next 48 to 72 hours. The article also includes weather maps for longer-term outlooks and a six-day World weather outlook.

We start with the U.S. Information. You can update this section here but these are 48 to 72-hour forecasts so if I have not been able to update this area twice daily, what is shown is still valid and the images in the body of the article update automatically but sometimes they are a bit slow to update.

Notices: Recently we published an article on a court decision that relates to whether or not states can decline to store out-of-state nuclear waste and you can access that article HERE. It is part of a series of articles I am writing on nuclear waste storage which is a huge problem for the world and the U.S. and I urge readers to read this court decision.


We also just published the annual State of the Climate Report for 2022 which is prepared by NOAA (NCEI) and the AMS.  For those interested in Global Warming it is a must-read and can be accessed HERE.

First, the 48-Hour Forecast (It is a 48 to 72 Hour Forecast actually)

Daily weather maps. The Day 1 map updates twice a day and the Day 2 and 3 maps update only once a day. These maps update automatically. But if that does not happen, you can get updates by clicking HERE

Continuation of the NWS Short Range Forecast. It is updated by NWS twice a day and these updates can be found here

Hurricane Lee will continue to track north over the next couple of days,
moving west of Bermuda late today and early Friday, before tracking east
of southern New England on Saturday. Due to the large size of the system,
hazards will extend well away from the center. This includes tropical
storm conditions which are possible in portions of coastal New England,
including Cape Cod, Nantucket, Martha’s Vineyard, and Block Island
beginning Friday night. By early Saturday, tropical storm conditions are
expected to reach as far north as Down East Maine. As the storm tracks
north, there is the potential for life-threatening storm surge flooding in
portions of southeastern Massachusetts, including Cape Cod and Nantucket
late Friday and Saturday. Swells generated by lee continue to affect much
of the East Coast — producing life-threatening surf and rip current
conditions.

A series of upper level disturbances interacting with a moist atmosphere
will continue to produce rounds of showers and thunderstorms from eastern
New Mexico, across much of Texas, and portions of Oklahoma. Heavy
rainfall amounts are possible and flooding may occur especially across any
areas where multiple rounds of storms develop. Isolated strong to severe
storms, producing damaging wind and hail are also possible.

Farther north, a cold front accompanied by showers and thunderstorms will
advance east from the northern Plains into the upper Great Lakes, while
sagging south through the central Plains and Rockies. Heavy rainfall
amounts are possible, especially for portions of the central Rockies,
which may result in localized flooding.

Below is the current five-day cumulative forecast of precipitation (Updates can be found HERE)

Now we look at Intermediate-Term “Outlook” maps 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 as deviation from normal and the likelihood of these deviations.

Below are the links to obtain updates and additional information. They are particularly useful if you happen to be reading this article significantly later than when it was published. I always try to provide readers with the source of the information in my articles.

Days 6 – 10 (shown in Row 1) Days 8 – 14 (Shown in Row 2) Weeks 3 and 4 (Shown in Row 3 but updates only on Fridays)
https://www.cpc.ncep.noaa. gov/products/predictions/610day/ https://www.cpc.ncep   .noaa.gov/products/predictions/814day/ https://www.cpc.ncep.noaa.gov/products/predictions/WK34/

Showing the actual maps. They should now update automatically. The Week 3 – 4 Outlook only updates on Fridays. So below is what I call the Intermediate-term outlook. On Fridays, it extends out 28 Days. That declines day by day so on Thursday it only looks out 22 days until the next day when the Week 3 – 4 Outlook is updated and this extends the outlook by one additional week.

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. I update almost all the images Friday Night for the weekend edition of this Weather Report.  So normally readers do not need to update these images but if the weather is changing quickly you may want to.
