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.
Short Range Forecast Discussion
NWS Weather Prediction Center College Park MD
Valid 00Z Wed Nov 08 2023 – 00Z Fri Nov 10 2023…Cooler temperatures and beneficial precipitation expected through
midweek across the northern tier states……Very warm weather including some record high temperatures can be
expected along with dry conditions for much of the Central and Eastern
U.S. through the middle of the week……Some rain to begin impacting parts of the South by Thursday…
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
TODAY (or late in the day the evening/overnight map will appear)
TOMORROW
NEXT DAY

The NWS Climate Prediction Center’s: Watches, Warnings, and Advisories plus other information can be found HERE. We post at least one of those updates daily, sometimes both. The Highlights are shown in the lede paragraph of this article.
ATMOSPHERIC RIVERS
This tells us what is approaching the West Coast. Click HERE to update If I have not gotten around to doing the update. Here is some useful information about Atmospheric Rivers.
Continuation of the NWS Short Range Forecast. It is updated by NWS twice a day and these updates can be found here
An upper level trough advancing eastward across the northern tier states
will keep unsettled conditions in store for the next few days. As the
upper trough moves through the west-central portions of the country cool
Pacific moisture will advect into the West resulting in below seasonal
normal temperatures along with scattered rain/snow showers for the Pacific
Northwest and Northern Rockies. The snow likely remain confined to the
highest elevations of the Cascades and Northern Rockies. In its wake high
pressure will build over the West Wednesday and Thursday while lingering
precipitation tapers off.Diffluence associated with the aforementioned upper trough will generate
light mixed precipitation from the Northern Plains to the Northeast
through the end of the week. A deep mid-latitude cyclone will have
developed by Thursday over the Midwest and will spread showers and
isolated thunderstorms into the interior Northeast. Showers and
thunderstorms will also develop along the attendant cold front over the
Southern Plains and Lower Mississippi Valley by then. Cooler air will
filter into the Upper Midwest, Great Lakes and the Northeast on the
backside of the low pressure system. Meanwhile, snow showers will spread
south across the Colorado Rockies on Wednesday into Thursday morning.
There is a Critical Risk for wildfires today given the the dry and windy
conditions over the Southern High Plains of eastern New Mexico into the
Texas Panhandle. Southerly flow across the Central and Southeastern U.S.
will produce anomalous warmth for much of the Great Plains to the East
Coast before the cold front sweeps through on Thursday. Many places from
the Southern Plains to the Central/Southern Appalachians may experience
record high temperatures today and Wednesday.

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.
