Continuation of the NWS Short Range Forecast. It is updated by NWS twice a day and these updates can be found here
There are three storm systems that are and/or will be impacting the CONUS
over the next few days. The first of the three is the major winter storm
bringing heavy snow and strong winds to the Northeast and Central
Appalachians today. Additional snowfall of 4-8 inches are expected for
much of the aforementioned areas through tonight when the storm is
expected to pull away into the Atlantic. Winter Storm Warnings and Winter
Weather Advisories are in effect. Conditions should improve on Monday.The second storm system is one that will make its way through the Rockies
today. Heavy snow is likely across much of the Intermountain West and
Central/Southern Rockies. Snow is also likely over the Northern Rockies
but to a lesser extent. This system will reorganize over the Southern
Plains on Monday and develop into a deep and dynamic mid-latitude cyclone.
This storm will generate heavy snow and strong winds over the Plains and
Midwest on Monday and Tuesday. The heaviest snow totals are most likely in
parts of the Midwest, where local maxima up to 12 inches are likely.
Blizzard conditions are most likely in the Central Plains where wind gusts
in excess of 50 mph will lead to near zero visibility at times and
extremely dangerous travel. Blizzard conditions are possible in the
Midwest as well. Winter Storm Watches are in effect for parts of the
Southern High Plains, Central Plains and Middle Mississippi Valley.Widespread and potentially significant river and flash flooding are likely
from the central Gulf Coast through much of the Eastern U.S. early this
week. 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 in some areas, especially in the Carolinas and
Mid-Atlantic. There is a Slight Risk of Excessive Rainfall leading to
Flash Flooding for portions of the Gulf Coast. Storms will support 1.5 to
2.5 inch/hr rain rates with localized amounts of 4 to 6 inches possible.
There is a Slight Risk of Severe Thunderstorms Monday through Monday night
across parts of southeast Texas, southern Louisiana, southern Mississippi,
southern Alabama into the western Florida panhandle. Damaging wind gusts
and tornadoes are possible across those areas by late Monday night.
Widespread wind gusts in excess of 50 mph are likely in the eastern Gulf
Coast so prepare for power outages.The third system arrives over the Pacific Northwest tonight. A deep
Pacific storm system will generate heavy coastal rain, heavy mountain snow
and strong winds across the region beginning tonight and continuing
through at least midweek. This major winter storm will bring several feet
of snow to the Washington and Oregon Cascades and will peak 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.
