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.

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).

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 deep and dynamic mid-latitude cyclone will organize over the
Central/Southern Plains this morning. Snow will develop in the Plains
today and advance into the Midwest tonight and Tuesday. Bursts of heavy
snow may accumulate up to two inches in an hour, and result in hazardous
travel. A heavy, wet snow will also develop in the interior Northeast
Tuesday afternoon and night. A blizzard is expected in the Plains of
northeast New Mexico, eastern Colorado, the Oklahoma and Texas Panhandles,
western Kansas and southwest Nebraska. Wind gusts as high as 60-70 mph
will create ferocious blizzard conditions with whiteouts. Travel will
become extremely dangerous to impossible. If you must travel, pack a
winter survival kit as wind chills will plummet below zero.There is an Enhanced Risk of Severe Thunderstorms across the central Gulf
Coast tonight into early Tuesday morning. Severe thunderstorms capable of
producing strong wind gusts and tornadoes are expected from southeast
Texas across the central Gulf Coast this afternoon into early Tuesday
morning. This Enhanced Risk of Severe Thunderstorms shifts into parts of
southeastern Alabama, northern Florida and parts of the Carolina
Piedmont/Coastal Plain on Tuesday. Very strong and damaging winds as well
as a few tornadoes will be the main threats.Widespread and potentially significant river and flash flooding are likely
for the central Gulf Coast and Eastern U.S. through early Wednesday.
Powerful onshore winds will lead to widespread coastal flooding along the
eastern Gulf Coast and much of the East Coast. Significant coastal
flooding is likely, especially on the Mid-Atlantic coastline, including
tidal rivers and bays. There’s a Moderate Risk of Excessive Rainfall
leading to Flash Flooding over parts of southeast Louisiana, southern
Mississippi and southwestern Alabama today where several inches of
rainfall may accumulate. The Moderate Risk of Excessive Rainfall shifts
into the Mid-Atlantic on Tuesday between northern Virginia, up the I-95
corridor and into western Massachusetts, where existing snowpack from the
recent snowstorm may cause additional runoff concerns. Widespread wind
gusts in excess of 50 mph are likely in the eastern Gulf Coast, Central
Appalachians, much of the East Coast and New England. Prepare for power
outages.Elsewhere, yet another pair of powerful winter storm systems will cross
the Pacific Northwest tonight and Tuesday night with several feet of heavy
snow and strong winds expected across the Cascades. Blizzard conditions
are likely. Snow levels rise to around 5000′ tonight with an atmospheric
river, but will quickly fall to between 1500 and 2500 feet behind a cold
front on Tuesday, leading to considerable impacts for many mountain passes
with the second storm Tuesday night. Over a foot of snow is likely
(70-90%) in the higher elevations of the Northern Rockies on Tuesday and
Wednesday.

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 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.
