It is difficult to find a more comprehensive Weather Outlook anywhere else with the ability to get a local 10-day Forecast also.
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 U.S. outlooks and a six-day World weather outlook which can be very useful for travelers.
First the NWS Short Range Forecast. The afternoon NWS text update can be found here but it is unlikely to have changed very much. The images in this article automatically update.
Short Range Forecast Discussion
NWS Weather Prediction Center College Park MD
Wed Mar 20 2024
Valid 12Z Wed Mar 20 2024 – 12Z Fri Mar 22 2024…Snow showers and gusty winds forecast throughout the Northeast over the
next few days……Light to moderate snow spreads from the northern Plains to the Great
Lakes by Friday……Shower and thunderstorm chances return to the Southern Plains and Gulf
Coast…A rapidly deepening low pressure system maturing over eastern Maine early
Thursday is anticipated to produce periods of snow across the Interior
Northeast and New England, while also reinforcing lake effect snow showers
in its wake. High probabilities (80-90%) for at least 4 inches of snow
exist across much of northern and central Maine, with lower probabilities
extending into northern Vermont, New Hampshire, and Upstate New York.
Gusty westerly winds up to 50 mph are also possible across parts of
Vermont and Maine on Thursday as the potent storm system creates a tight
pressure gradient over the Northeast. Additionally, the cold and dry
airmass in place combined with gusty winds will create fire weather danger
throughout the Mid-Atlantic. Red Flag Warnings have been issued across
much of Virginia.A separate winter storm is anticipated to produce a swath of snow between
the northern Plains and Great Lakes by the end of the week, with snow
beginning today across the northern High Plains. A wave of low pressure
developing over a lingering stationary front will help trigger the
developing precipitation shield and shift snowfall eastward by Thursday
night. High probabilities for at least 4 inches of snow exist across
northwest Montana, with medium to high probabilities (40-80%) extending
from north-central Montana to central Minnesota, including southern South
Dakota. Greater chances for moderate to heavy snow shifts to the Upper
Midwest and Great Lakes by Friday, where there is the potential for up to
10-12 inches of snow. Residents should remain weather aware and up to date
with the latest forecast as uncertainty remains regarding the exact
location of heavy snowbands.Elsewhere, unsettled weather is set to return to the southern Plains, Gulf
Coast, and parts of the West Coast. An upper low lingering over the
Southwest is expected to finally eject into the southern Plains tonight
and spark showers and thunderstorm over portions of Oklahoma and Texas. By
Thursday, rain could become heavy enough along the western Gulf Coast and
southeast Texas to produce isolated flooding concerns. This system is
forecast to progress eastward into the Gulf of Mexico on Friday, spreading
showers and thunderstorms along the entire Gulf Coast, as well as
eventually Florida and the Southeast by late Friday. However, both the
severe and flooding threat associated with this system remain marginal.
For the West Coast, light to moderate rain is expected to move inland
across northern California and the coastal Midwest on Friday. As the axis
of precipitation along a frontal boundary intersects the Sierra on Friday
night, heavy snow is possible throughout the mountainous terrain.

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).

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.
Below is the current five-day cumulative forecast of precipitation (Updates can be found HERE)
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 2
Additional snow information can be found here, here, 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. These links may also be useful for those viewing this article on a cell phone or other small screen.
| 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.
