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 which updates frequently on those storms.
Please click on “Read More” below to access the full report as I have moved the highlights into the body of the report where it is followed by the Today, Tomorrow and the Next Day maps and a lot more. I will try to feature the most important graphic in the lede paragraph on the home page. But there are often multiple maps that are very important so it is best to read the full article. We now have a snow report and it is possible to get a ten-day NWS forecast for the zip code of your choice.

First the highlights from the NWS.
Short Range Forecast Discussion
NWS Weather Prediction Center College Park MD
Thu Dec 28 2023
Valid 12Z Thu Dec 28 2023 – 12Z Sat Dec 30 2023…Scattered areas of mixed rain and snow over the central to the eastern
U.S. continue to rotate around the weakening but huge circulation of the
former winter storm……Heavy rain and flood threat associated with a coastal low expected to
depart northern Mid-Atlantic/southern New England later this morning……Unsettled weather lingers near the West Coast for the next couple of
days……Above normal temperatures across the northern tier will be contrasted
with below average temperatures across the southern tier…
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
TODAY (or late in the day the evening/overnight map will appear) (Key to surface fronts shown on maps and you will then also be able to insert a city name or zip code and get a local NWS forecast).
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
Although all winter weather warnings and advisories related to the most
recent blizzard across the northern and central Plains have been
discontinued, the huge upper-level circulation associated with the storm
will take some time to spin down. The remaining mixed rain/light snow
over central Plains is expected to taper off by later this afternoon.
Meanwhile, some wrap-around moisture from the Great Lakes is forecast to
rotate southward into the Midwest to provide mixed rain and wet snow today
before tapering off this evening. Some heavier, but brief, snowfall may
occur within this area of precipitation. Nevertheless, only minor snow
accumulations are expected due to temperatures hovering just above
freezing.In the East, a strengthening coastal low tracking just off the
Mid-Atlantic states is spreading an area of moderate to heavy rain across
the northern Mid-Atlantic into southern New England early this morning.
The heavy rain may produce excessive runoff, resulting in the flooding of
rivers, creeks, streams, and other low-lying and flood-prone locations.
Onshore winds along with astronomical high tide are expected to produce
minor coastal flooding along vulnerable waterfront and shoreline areas in
the New York City metro into this morning. The moderate to locally heavy
rain should move across southeastern New England this afternoon as the
coastal low tracks southeast of Long Island. By Friday, the low will
begin to move east of New England slowly, with some bands of moderate rain
possibly rotate back toward southeast New England coast later in the
afternoon. On-and-off rain showers can be expected to linger across much
of the remaining Northeast, possibly changing to light wet snow over Maine
on Friday. Light wet snow is expected to linger along the Appalachians as
well.Across Florida, a round of rain is forecast to pass southern Florida today
as a subtropical jet stream in conjunction with a wave of low pressure
will be in the vicinity.Meanwhile, moisture well ahead of a couple of large Pacific cyclones is
forecast to produce unsettled weather along the West Coast for the next
couple of days. These systems will generate rain and high elevation snow
over the Pacific Northwest and California, while much of the reminder of
the western U.S. is forecast to remain dry. Mixed precipitation is
forecast to reach into the Great Basin by Saturday morning.Under this anomalous weather pattern, milder than normal temperatures will
be found across the northern tier of the country into much of the western
U.S. while cooler than normal conditions will shift slowly across the
southern tier toward the southeastern U.S. through the next couple of
days. In fact, mild overnight temperatures will be more than 20 degrees
above normal from the northern Plains to the Northeast where record warm
minimum temperatures will likely be established especially this 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 Econcurrents 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. And remember this shows natural snow. Ski resorts also make their own snow.
Day 1
Day 2
Additional snow information can be found here and here. The second link provides animations.
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.

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.
