Short Term and Intermediate-Term Weather Outlooks for the U.S. and a Six-Day Forecast for the World: posted November 3, 2023

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.

…Great Plains warm up this weekend…

…Several rounds of moderate to locally heavy precipitation to continue
into portions of the Pacific Northwest, Northern Rockies and northern
California this weekend into early next week…

Notices: We just published a review of September weather worldwide and you can access that article HERE. And a review of September weather for the U.S. which you can access 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

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

Waves of low pressure will continue bringing moderate to heavy rainfall
and mountain snow to the Northwest CONUS this weekend into early next
week. Locally heavy rainfall may cause isolated instances of flash
flooding along the coastal ranges of the Pacific Northwest this weekend.
Thus, there’s a Marginal Risk of Excessive Rainfall leading to Flash
Flooding extending from coastal Washington down to the northern California
coast through Sunday. Between 2-4 inches of rainfall are expected with
locally higher amounts, especially over terrain through the end of the
weekend.

Elsewhere, shortwave energy moving through the Mississippi Valley will
generate light rain/snow showers from the Northern Plains, across the
Great Lakes and into the interior Northeast this weekend. Beneath the
upper troughing over the northern tier will reside high pressure and
southerly flow into the Great Plains. With this comes warmer temperatures
for much of the Central U.S.. High temperatures in the upper 60s to low
80s will be 15-25 degrees above average for the Central/Southern High
Plains. The arrival of one shortwave on the heels of another will support
a quick rebound in temperatures for the Southeast this weekend.

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.

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.
