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 highlights from the NWS.

Continuation of the NWS Short Range Forecast. It is updated by NWS twice a day and these updates can be found here
A wave of low pressure over the Lower Mississippi Valley moves
northeastward to the Mid-Atlantic by Sunday, then out over the Western
Atlantic by Monday. Moisture will surge northward over the Southeast into
the Mid-Atlantic, producing heavy rain. Therefore, the WPC has issued a
Slight Risk of excessive rainfall over parts of the Central/Southern
Appalachians and Mid-Atlantic through Sunday morning. The associated heavy
rain will create mainly localized areas of flash flooding, with urban
areas, roads, and small streams the most vulnerable. Moreover, light snow
will fall over parts of the Lower Great Lakes along the northern edge of
the precipitation shield.Additionally, showers and severe thunderstorms will develop over parts of
the Southeast. Therefore, the SPC has issued a Slight Risk of severe
thunderstorms over parts of the Southeast through Sunday morning. The
hazards associated with these thunderstorms are frequent lightning, severe
thunderstorm wind gusts, few tornadoes, and a minimal threat of hail.On Sunday, rain will continue over the Ohio Valley to the Mid-Atlantic and
showers and thunderstorms will develop over parts of Coastal Mid-Atlantic
into Florida. However, the threat of severe thunderstorms and excessive
rainfall will end on Sunday.Also, as the precipitation shield moves into colder air on Sunday, snow
will develop from parts of the Ohio Valley/Lower Great Lakes to New
England. Heavy snow will develop over parts of Northern New England, while
pockets of rain/freezing rain will develop from parts of eastern New York
State into Southern New England. Snow will also develop over parts of the
Central/Southern Appalachians. By Monday morning, the area of low pressure
will be over the Western Atlantic.Meanwhile, moisture will stream into the Pacific Northwest and Northern
California, mainly producing rain and highest-elevation snow in a few
places. The rain will continue over the Pacific Northwest through early
Sunday afternoon. The rain will be over by Monday 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 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.
| 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.
