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.

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

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.

Continuation of the NWS Short Range Forecast. It is updated by NWS twice a day and these updates can be found here
The main theme to our weather story over much of the Lower 48 remains the
brutally cold temperatures and associated significant wintry weather.
Little has changed with the “take-home” message regarding the dangerous
cold entrenched over the U.S, as sub-zero air temperatures and even colder
wind chills prevail through tomorrow before another Arctic blast arrives
late this week. This means one more day of frigid wind chills dipping
below minus 30 across the Plains states, and minus 50 in Montana and the
Dakotas. As we approach mid-week (Wednesday), the initial Arctic airmass
will moderate, leading to below average (but still cold) temperatures east
of the Continental Divide. Unfortunately, another surge of frigid Arctic
air is expected to plunge southward out of Canada later this week, which
could lead to more of the same dangerous cold weather across the Midwest
and Deep South by the end of the work week. Stay tuned for details as the
forecast evolves.In the more immediate term, the frigid airmass in place is also supporting
hazardous winter weather across much of the Southern U.S and Great Lakes.
Widespread moderate to locally major potential winter storm impacts today
are expected across the Lower Mississippi Valley and Tennessee Valley as a
mix of snow, sleet, and freezing rain fall before spreading into the
Appalachians. Impacts from this storm today may be prolonged even after
the wintry precipitation subsides, owing to the Arctic air in place. By
later today into tomorrow, snowfall is expected to reach the Appalachians
and Mid-Atlantic, including Washington D.C, Philadelphia, and New York.
Regardless of how much falls, prepare for slippery road conditions
beginning later today into tomorrow.Meanwhile, periods of heavy lake effect snowfall will continue downwind of
the Great Lakes through Wednesday, with heavy accumulations focused across
northern Michigan, western and Upstate New York including Buffalo. In
these areas, moderate to major winter weather impacts can be expected,
where localized Winter Storm Watches and Warnings are in effect.

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, 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.
