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
An upper disturbance centered over the Great Lakes will support a winter
storm across the eastern third of the country this weekend. Expect heavy
snow in interior portions of the northern Mid-Atlantic through New England
this afternoon into Sunday. There is a high chance (50-90%) of exceeding
8″ of snow from central Pennsylvania east through much of south-central
New England. Local snowfall over 12 inches of snow is possible within the
heaviest bands. The combination of heavy, wet snow and gusty winds from
northeast Pennsylvania through much of the southern and central New
England will result in difficult travel with some power outages and tree
damage. Gusty onshore winds may lead to minor flooding along the
Mid-Atlantic and southern New England coasts during the Sunday morning
high tide cycle. The probability for ice accumulations in excess of 0.25″
along the Blue Ridge of North Carolina and Virginia are 30-50%. This icing
along with some areas of sleet, may produce hazardous travel conditions
today. Winter Storm Watches Warnings and Winter Weather Advisories are in
effect for portions of the Central Appalachians and interior Northeast.
Meanwhile, rain showers and scattered thunderstorms are likely across the
southern Mid-Atlantic and Southeast within the warm sector of the winter
storm today.The next winter storm shifts down the West Coast today crossing the Desert
Southwest Sunday before rapidly strengthening over the Southern
Rockies/Plains Sunday night/Monday. Expect heavy snow in the higher
elevations near the West Coast and Four Corners states this weekend before
a swath of heavy snow develops over parts of the Southern/Central Plains
on Monday. Gusty winds on the warm side of the storm may exceed 50 MPH and
cause damage over the Appalachians to the East Coast. Organized severe
thunderstorms are possible along the Gulf Coast and Southeast Monday and
Tuesday. There is a Slight Risk (at least 15%) of Excessive Rainfall
leading to Flash Flooding across portions of the central Gulf Coast on
Monday. Yet another storm system will arrive over the Pacific Northwest on
Monday, bringing with it coastal showers and mountain snow.

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 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.
