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
An upper-level disturbance will bring heavy rain to the coasts of northern
and central California today. A Slight Risk of Excessive Rainfall (level
2/4) leading to Flash Flooding is in effect between Humboldt and Sonoma
Counties where some instability could promote isolated thunderstorm
activity. The Pacific moisture responsible for this heavy precipitation
will flow into the Trinity and Shasta mountains of northern California, as
well as the Sierra Nevada today. Between 6-12 inches of snow are expected
for the Sierra while 1-3 feet are likely for the Trinity and Shasta
mountains.On Sunday, the previous upper-level energy will propagate into the
Intermountain West and Northern Rockies, where it’ll generate snow showers
for those areas, while a more potent closed low system moves closer to the
West Coast. Another round of heavy rainfall is likely to spread across
California on Sunday out ahead of a surface low pressure system supported
by the aforementioned upper low. Another Slight Risk of Excessive Rainfall
is in effect for much of the California coast from Humboldt County down to
Ventura County. Heavy rainfall over saturated soils could cause runoff
concerns, particularly over Santa Barbara where 2-4 inches of low
elevation rain and 4-8 inches in the Transverse Range/other favored
terrain will cause Flash Flooding. Another round of 6-12 inches in the
Sierra and 1-3 feet over the Trinity and Shasta are also expected on
Sunday.Meanwhile, rain and thunderstorms will develop over the Florida Peninsula
today along a cold front moving southeast across the state. The front will
stall over central Florida on Sunday and an area of low pressure is
forecast to develop just off the state’s east coast. This surface wave
will focus heavy rain and thunderstorms across the peninsula that day.
Cool air will spread across the southeastern U.S. today and tomorrow
behind the synoptic cold front mentioned above. Milder temperatures build
over the Great Plains and Midwest into next week. Lake effect snow likely
downwind of the Great Lakes this weekend.

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.
