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.

Valid 12Z Fri Sep 08 2023 – 12Z Sun Sep 10 2023…Severe storms possible today across portions of the Northeast, Mid
Atlantic, and from the Red River to the upper Texas and Louisiana coasts
……Dangerous heat continues across parts of the Northeast, south-central
U.S., and the Southwest……Increasing chance for heavy rain across portions of the Southeast on
Saturday…
| Notices: Recently we published the NOAA mid-month update for September and you can access that article HERE.
We also 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. |
First, the 48-Hour Forecast (It is a 48 to 72 Hour Forecast actually)

Continuation of the NWS Short Range Forecast. It is updated by NWS twice a day and these updates can be found here
A cold front will continue to advance slowly east across the eastern U.S.,
focusing rounds of showers and thunderstorms through the period. Storms
that develop across the Northeast and Mid Atlantic today may become
severe, with hail and damaging winds possible. In addition to the severe
weather threat, some areas may see locally heavy rainfall amounts, with
isolated flash flooding possible. Albeit a few degrees cooler from
previous days, temperatures will remain unseasonably warm ahead of the
front. Heat advisories remain in effect today for portions of the
Northeast, including the New York City metro and parts of southern New
England, where heat indices will once again climb well into the 90s.The front is expected to make little forward progress into the weekend.
While the potential for strong to severe storms is expected to diminish,
the threat for heavy rainfall is forecast to increase for some areas,
especially for the southern Appalachians and Piedmont, as a slow-moving
upper disturbance interacts with moisture along and ahead of the front.Farther to the west, storms developing this morning across eastern Kansas
and Oklahoma into the Ozark region are expected to drop south, with some
intensification possible as this activity moves toward the Gulf Coast
later today. Additional storms may develop near the Red River and track
south across eastern Texas later today as well. Storms that develop
across this area will have to the potential to produce hail and damaging
winds.Near and west of this activity, an upper-level high will persist,
supporting well-above normal temperatures across much of the south-central
U.S. today and record-breaking heat across much of Texas today and into
the weekend. Excessive Heat Warnings and Heat Advisories cover much of
Texas and portions of Oklahoma and Louisiana, where heat indices may reach
above 110F in some locations.Portions of the Southwest will remain hot as well, with temperatures
expected to climb a few degrees further as the upper high shifts farther
west over the weekend. An Excessive Heat Warning has been issued this
weekend for portions of southern Arizona and southern California, where
temperatures in the lower deserts may climb into the 110s.Farther to the north, a system will bring showers and storms followed by
cooler weather as it moves from the northern Rockies into the High Plains
today and the northern to central Plains/Upper Midwest on Saturday.

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) |

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.
