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 Thu Sep 07 2023 – 12Z Sat Sep 09 2023… On Thursday, there is a Slight Risk of severe thunderstorms over parts
of the Northeast and Mid-Atlantic/Central Appalachians……There are Heat Advisories and Excessive Heat Warnings over parts of the
Southern Plains/Lower Mississippi Valley and Heat Advisories over the
Northeast on Thursday……Air Quality Alerts over parts of the Central Plains, Upper Mississippi
Valley, and Maine on Thursday…
| 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)
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
On Thursday, a front extending from the Great Lakes/Ohio Valley, Tennessee
Valley, Lower Mississippi Valley, and Southern Plains will move eastward
to the Eastern Sea Board and Gulf Coast by Saturday. The system will
create showers and thunderstorms from the Northeast to the Eastern Gulf
Coast on Thursday. The front will also produce showers and severe
thunderstorms over parts of New York State, eastern Pennsylvania, and
Mid-Atlantic. Therefore, the SPC has issued a Slight Risk of severe
thunderstorms over parts of the Northeast and Mid-Atlantic/Central
Appalachians through Friday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a minimal threat of tornadoes.On Friday, the threat of severe thunderstorms continues. As the front
moves eastward, showers and severe thunderstorms will develop over parts
of Southern New England to the northern Mid-Atlantic. Therefore, the SPC
has issued a Slight Risk of severe thunderstorms over parts of Southern
New England to the northern Mid-Atlantic from Friday into Saturday
morning. The hazards associated with these thunderstorms are frequent
lightning, severe thunderstorm wind gusts, hail, and a minimal threat of
tornadoes. Once again, showers and thunderstorms will extend from the
Northeast southward to the Southeast on Friday.Meanwhile, on Thursday, a weak front extending from the Northern Plains to
the Southern Plains will aid in producing showers and thunderstorms over
the area with a threat of strong to severe thunderstorms. In addition,
another slow-moving front over the Northern Rockies will move eastward to
the Northern Plains/Upper Mississippi Valley by Saturday. The boundary
will produce showers and thunderstorms over parts of the Northern Rockies
late on Thursday. On Friday, the showers and thunderstorms will expand
into the Northern High Plains and Northern Plains overnight Friday into
Saturday.On Friday, a wave of low pressure over the Southern plains will add in,
producing showers and severe thunderstorms over parts of northeastern
Texas and extreme southeastern Oklahoma. Therefore, the SPC has issued a
Slight Risk of severe thunderstorms over parts of the Southern Plains from
Friday into Saturday morning. The hazards associated with these
thunderstorms are frequent lightning, severe thunderstorm wind gusts,
hail, and a minimal threat of tornadoes.Moreover, smoke from wildfires in West-Central Canada will reduce air
quality over parts of the Central Plains and Upper Mississippi Valley,
prompting Air Quality Warnings over the area. Additionally, wildfire smoke
over Eastern Canada will drift into Maine, starting Air Quality Warnings
over Maine.Lastly, upper-level ridging will linger over parts of the Northeast on
Thursday. Unfortunately, the hot temperatures will remain over New
England, prompting Heat Advisories over the area. In addition, an
upper-level high will return to Texas on Thursday, aiding in developing
hot temperatures over the region, prompting Heat Advisories and Excessive
Heat Warnings over the Southern Plains/Lower Mississippi Valley. The hot
temperatures will continue over the area through 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.
