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
Thu Nov 02 2023
Valid 12Z Thu Nov 02 2023 – 12Z Sat Nov 04 2023…Record cold subfreezing temperatures this morning across much of the
South before a gradual warm up by this weekend……Wet weather pattern in place across the Pacific Northwest as several
rounds of moderate to locally heavy rain impact the region…
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
This animation shows how things may play out over the next 60 hours. To update click here.
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
A large area of high pressure stretching from the Northeast to the
southern Plains will allow for a frigid morning across much of the central
and eastern United States. In fact, record cold is possible for several
locations from Louisiana to Maine in the form of daily record low
temperatures. Readings into 20s and 30s are likely to be widespread, with
localized teens possible in the typical cold valley locations just before
sunrise. The main impacts associated with these temperatures will be the
first freeze of the season for many locations. Sensitive plants could be
damaged or killed and exposed pipes could burst if proper precautions are
not taken. Freeze Warnings extend from eastern Texas to southern
Pennsylvania and New Jersey. Fortunately, for those who dislike the cold,
conditions should gradually warm with temperatures reaching closer to
average for this time of year by Saturday.On the opposite side of the country, unsettled weather is set to remain
across the Pacific Northwest as a few Atmospheric Rivers move inland over
the region. The first batch of precipitation is ongoing this morning and
will spread moisture into the northern Rockies through tonight. Snow
levels will be rather high, with most snowfall accumulations located
across the Yellowstone region, northwest Montana, and the highest terrain
of the northern Cascades. Localized small stream and urban flooding is
possible across the Cascades and coastal ranges. By Friday night the next
round of moderate to locally heavy rain is expected to push inland and
create additional chances for localized flooding. Recent burn scars will
be most susceptible to flash flooding near northwest California and
southwest Oregon.Mostly dry and tranquil conditions are forecast through Saturday across
the remainder of the CONUS. Warming temperatures will lead to widespread
highs into the 60s and 70s by Saturday from the Southwest and
central/southern Plains to the Mid-Atlantic, making for a picture-perfect
first weekend of November. Meanwhile, strong northeasterly winds behind a
cold front will make for blustery conditions and rough surf across much of
the Florida coastline

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.
