It is difficult to find a more comprehensive Weather Outlook anywhere else with the ability to get a local 10-day Forecast also.
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.
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 quick moving low pressure system will sweep across the Southeast and
Tennessee Valley today before exiting into the Western Atlantic later
tonight. An area of light to moderate snowfall will develop over the
northern periphery of this system, going on to produce a general swath of
2-4″ of snow from eastern Missouri to southern New Jersey/Delaware.
Heavier snowfall will occur over the Central Appalachians of West Virginia
into the Maryland Panhandle where 4-6″ with locally higher amounts are
possible. The timing of this snowfall could cause issues during rush hour
commutes across the Midwest today. Late night travel could be dicey from
the DC up to Philadelphia metros this evening.Elsewhere, a deep southern stream trough will support rain showers and
thunderstorms across parts of the Texas/Central Gulf Coast through
tonight. Shortwave energy moving through the Rockies will promote moderate
to heavy snowfall over the Northern and Central portions of the mountain
range through this evening as well. An Arctic airmass will work it’s way
through the Central and Southern parts of the country this weekend as an
associated Arctic cold front propagates through. Temperatures across parts
of the Great Plains, Mississippi Valley and eventually Southeast will be
between 15-25 degrees below average this weekend.A deep upper-level low over the Eastern Pacific will send a plume of
moisture into the West coast on Saturday. This moisture will be supported
by a low pressure system and an attendant cold front at the surface. Heavy
Rain will develop across southern Oregon and northern California tonight
before spreading south into central/southern California on Saturday.
There’s a Slight Risk of Excessive Rainfall (level 2/4) leading to Flash
Flooding for portions of Humboldt County down to Sonoma on Saturday where
between 1-2″/hr rainfall rates are possible. Heavy snow will develop over
the Sierra Nevada and Shasta/Trinity on Saturday night as Pacific moisture
move inland. Another low pressure system will bring yet another round of
heavy precipitation to California on Sunday. Heavy rainfall from the prior
day in addition to the general sensitivity of California’s coastal areas
to heavy rainfall will support a Slight Risk of Flash Flooding from
Humboldt County down to Ventura on Sunday. This moisture will eventually
shift into the Sierra and Trinity/Shasta once again, and will support
additional moderate to heavy snowfall over those mountain ranges. A total
of 1-2 feet of snow are possible over the Sierra this weekend while 1-3
feet are more likely over the Trinity and Shasta Mountains.

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. These links may also be useful for those viewing this article on a cell phone or other small screen.
| 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.
