This article focuses on 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 which can be very useful for travelers.
We start with the U.S. Information. That is the longest part of the article. Then we have a short section on World Weather and then we address the Tropics. When there are tropical storms that might impact the U.S. we provide more detailed information on those storms which updates frequently.
Please click on “Read More” below to access the report as I have moved the highlights into the body of the report. Yes, indeed I have been able to add the Ski Report. I do not get paid for writing this article but I want to keep track of how many read it as that is how I can tell if I am providing the information that readers want and find useful. I have access to information that might be difficult to find for most readers.
| Notices: We recently published a review of October weather worldwide and you can access that article HERE. And a review of October weather for the U.S. which you can access HERE. We have now published the NOAA Seasonal Update which you can access HERE. What would you like to learn about? Please provide that to me via the comment section at the end of the article. |
First the highlights from the NWS.
Short Range Forecast Discussion
NWS Weather Prediction Center College Park MD
Sat Nov 25 2023
Valid 00Z Sun Nov 26 2023 – 00Z Tue Nov 28 2023…Winter weather possible for the return from the Thanksgiving holiday
from portions of the Southern to Central Plains into the Mid to Upper
Mississippi Valley and Western Lakes region..…Rain possible along the Gulf Coast and the Northern Mid-Atlantic to New
England coasts……Below average temperatures to spread eastward from the Plains into the
Mississippi and Ohio Valley region for the start of the work week……Tranquil weather on tap from the High Plains, west to the West Coast…
Now more detail on 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
The last part of the return trip from the Thanksgiving holiday will bring
the potential for accumulating snows and travel disruptions from portions
of the Central to Southern Plains, northeastward into the Mid to Upper
Mississippi Valley and western Great Lakes. This is in response to an
upper level low, that has already produced widespread heavy snows across
the Northern to Central Rockies, pushing northeastward from the Central
Plains into the Great Lakes and a more northern area of low pressure
moving along the south central Canada/north central U.S. border area into
the Great Lakes. Snowfall amounts are expected to be lighter than what
fell through the Northern and Central Rockies, with accumulations
generally in the 2 to 4 inch range. Travel disruptions also possible
along the immediate Gulf Coast from Texas to Florida as rainfall is
expected to develop across this region on Sunday. Stormy weather also
possible late Sunday into early Monday from the Northern Mid Atlantic
coast, northeastward along the New England coast as an area of low
pressure deepens across this area. This may produce some moderate to
locally heavy precipitation totals, but temperatures are expected to be
warm enough to keep the precipitation as rain.In the wake of the system pushing northeastward from the Plains into the
Great Lakes, below average temperatures will be spreading eastward Sunday
into Monday from the Plains into the Mississippi and Ohio Valley regions.
This cold air will then push into the eastern U.S. by Tuesday. As the
cold air pushes across the Great Lakes late Sunday into Monday, lake
effect snow showers will develop from west to east in the lee of the Great
Lakes. This will support locally heavy snowfall amounts across the
favored lake effect snow regions of the Upper Peninsula of Michigan, the
western portions of the Lower Peninsula of Michigan and from far northeast
Ohio, far northwest Pennsylvania into far western New York State and
northern New York State.Meanwhile, mostly tranquil weather expected from the High Plains, westward
through the Rockies and to the West coast as high pressure will remain
centered across the Central Rockies and provide for dry weather. The
clear skies and dry weather will bring the potential for freezing
temperatures over the next few mornings through the interior Valleys of
California where freeze warnings are in effect for Sunday morning.

Ski SnowReports
New Feature – Ski Reports. It is difficult to find reports that auto-update on-screen (and they are very long) but these links will get you to them – If you have additional suggestions make them in the comments section after every GEI Article and we may add those links. We will try to not have too much overlap as that can add to the confusion.
Snow Forecasts.
Day 1
Day 2
Here is another map but it is not the existing level of snow but the snowfall in the recent six hours.
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) |
| https://www.cpc.ncep.noaa. gov/products/predictions/610day/ | https://www.cpc.ncep .noaa.gov/products/predictions/814day/ | https://www.cpc.ncep.noaa.gov/products/predictions/WK34/ |
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.

HAZARDS OUTLOOKS
Click here for the latest complete Day 3 -7 Hazards forecast which updates only on weekdays. Once a week probably Monday or Tuesday I will update the images. I provided the link for readers to get daily updates on weekdays. Use your own judgment to decide if you need to update these images. 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.
