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 NWS Short Range Forecast. The afternoon NWS text update can be found here but it is unlikely to have changed very much. The images in this article automatically update.

…Powerful low pressure system to produce gusty winds and heavy rain
across parts of the Great Lakes, Ohio Valley, and Northeast through
Friday……Lower elevation rain and mountain snow to enter California on
Saturday……Well above average temperatures forecast to surge into the
northern/central Plains this weekend…A broad area of showers and thunderstorms across the Midwest and into the
Northeast will continue Friday as a deep cyclone over the Great Lakes
slowly shifts into Canada. Showers should taper off from west to east
across the Great Lakes/Ohio Valley as the low departs, with more moderate
to heavy rainfall most likely along the Appalachians into the Lower Great
Lakes. The heaviest rainfall is expected ahead of a trailing cold front
through New England where an influx of moist southeasterly flow off the
Atlantic along upslope portions of the northern Appalachians contributes
to some more potent storms and rain totals. A Slight Risk of Excessive
Rainfall (level 2/4) has been issued for portions of New Hampshire and
Maine along and ahead of the White Mountains where the combination of
heavy rain and snowmelt could lead to some instances of flooding. Some
lighter lingering showers will last into Saturday, particularly for
interior portions of the Northeast. Conditions will also remain breezy
across the region with Wind Advisories in place for portions of the Great
Lakes, Appalachians, and New England.In the West, some light lower elevation rain showers and higher
elevation/mountain snow showers will be possible along a frontal system
pushing southward through portions of the northern Great Basin and Pacific
Northwest Friday. An approaching Pacific system will bring higher
precipitation chances spreading southward into California later Friday and
into the day Saturday. Some moderate to locally heavy showers will be
possible along the coast, with accumulating snowfall expected for the
Northern Coastal Ranges, Klamath Mountains, and Sierra Nevada. A Winter
Weather Advisory has been issued for southern portions of the Sierra where
6-12 inches of snow is forecast. Gusty winds are expected here as well,
especially along the area mountain ranges.Cooler, below average temperatures will spread eastward from the Lower
Great Lakes/Ohio Valley/Tennessee Valley Friday into the
Northeast/Mid-Atlantic Saturday following recent cold front passage. Highs
will tend to be at or just below average further south into the Southeast
and Florida. A broad area of much above average temperatures across the
West/Plains Friday will expand into the Mississippi Valley Saturday as
upper-level ridging shifts eastward over the central U.S. The greatest
anomalies will reside over the northern and central Plains Saturday, where
highs into the 80s are upwards of 20-25 degrees above normal. Much cooler
temperatures will arrive in California Saturday as the Pacific system
begins to move inland.

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
TODAY (or late in the day the evening/overnight map will appear) (Key to surface fronts shown on maps and you will then also be able to insert a city name or zip code and get a local NWS forecast).
TOMORROW
NEXT DAY
This animation shows how things may play out over the next 60 hours. To update click 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.
Below is the current five-day cumulative forecast of precipitation (Updates can be found HERE)
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, 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.

Below are the Day 1 -3 and 4-6 forecasts for temperature and precipitation. Updates and much additional information can be obtained HERE
World Temperature Anomalies
World Accumulated Precipitation
This information is provided by the University of Maine. They draw upon many different sources. There is a lot of information available at the link provided. I have just provided two useful forecasts. There are probably over a hundred different forecasts available from this source.
Worldwide Tropical Forecast (This is a NOAA Product)
This graphic updates on Tuesdays) If it has not been updated, you can get the update by clicking here Readers will only have to do that if they are reading this article much later than the date of it being published.
Information on Tropical Storms can be found HERE. Western Pacific information can be found HERE. Note that unless there is an out-of-season storm the below images will not update until the National Hurricane Center starts their seasonal update of these maps on June 1. I include them simply because there can be an out-of-season event in which case it should show up in these maps.
