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 after about 4 p.m. New York time but it is unlikely to have changed very much from the morning update. The images in this article automatically update.
Short Range Forecast Discussion
NWS Weather Prediction Center College Park MD
Sun Jun 09 2024
Valid 12Z Sun Jun 09 2024 – 12Z Tue Jun 11 2024…There is a Moderate Risk of excessive rainfall over parts of the Middle
Mississippi Valley on Sunday……There is a Slight Risk of severe thunderstorms over parts of the
Northern/Central High Plains on Monday……There are Heat Advisories over parts of western Texas…
A front extending from the Mid-Atlantic southwestward to the Tennessee
Valley and then westward to the Central Rockies will move eastward to off
most of the Eastern Seaboard by Monday evening. Moisture pooling along the
boundary will aid in creating showers and thunderstorms with heavy rain
over southern Missouri. Therefore, the WPC has issued a Moderate Risk
(level 3/4) of excessive rainfall over parts of the Middle Mississippi
Valley through Monday morning. The associated heavy rain will create
numerous areas of flash flooding. Furthermore, many streams may flood,
potentially affecting larger rivers.Moreover, showers and strong to severe thunderstorms will develop along
the front from the Southeast to the Northern Intermountain Region.
Therefore, the SPC has issued a Marginal Risk (level 1/5) of severe
thunderstorms over parts of the Southeast, Tennessee Valley, lower
Mississippi Valley, Southern Plains, Central Rockies, and the Northern
Intermountain Region through Monday morning. The hazards associated with
these thunderstorms are frequent lightning, severe thunderstorm wind
gusts, hail, and a minimal threat of tornadoes.Meanwhile, a front over the Eastern Pacific will move inland to the
Pacific Northwest/Central California by early Sunday afternoon. On Sunday,
the boundary will produce showers and thunderstorms over parts of the
Pacific Northwest and Northern Intermountain Region. The front will
continue to move eastward to the Northern Plains by Monday. The front will
trigger showers and severe thunderstorms over parts of western South
Dakota, northwestern Nebraska, and extreme eastern Montana/Wyoming.
Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
thunderstorms over parts of the Northern/Central High Plains from Monday
through Tuesday morning. The hazards associated with these thunderstorms
are frequent lightning, severe thunderstorm wind gusts, hail, and a few
tornadoes.Further, the showers and thunderstorms will also cause heavy rain to
develop over parts of the Northern Plains/Upper Mississippi Valley.
Therefore, the WPC has issued a Marginal Risk (level 1/4) of excessive
rainfall over parts of the Northern Plains/Upper Mississippi Valley from
Monday through Tuesday morning. In addition, the associated heavy rain
will create localized areas of flash flooding, affecting areas that
experience rapid runoff with heavy rain.Furthermore, along the front over the Southern High Plains, showers and
thunderstorms will cause heavy rain to develop over parts of the region.
Therefore, the WPC has issued a Marginal Risk (level 1/4) of excessive
rainfall over parts of the Southern High Plains from Monday through
Tuesday morning. In addition, the associated heavy rain will create
localized areas of flash flooding, affecting areas that experience rapid
runoff with heavy rain.Elsewhere, tropical moisture and upper-level impulses will aid in
producing showers and thunderstorms with heavy rain over parts of southern
Florida. Therefore, the WPC has issued a Marginal Risk (level 1/4) of
excessive rainfall over parts of southern Florida from Monday through
Tuesday morning. In addition, the associated heavy rain will create
localized areas of flash flooding, affecting areas that experience rapid
runoff with heavy rain.Moreover, upper-level energy over the Great Lakes/Northeast will help
produce rain over parts of the Great Lakes and the Northeast through
Monday night. Furthermore, upper-level ridging over Texas helps spawn Heat
Advisories over parts of western Texas.

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
We have a new animation of the forecast which shows how things may play out over the next 60 hours. To update click ANIMATION. Doing so will get you to the dashboard. You can then step through the animation or hit LOOP on the upper right of the display. You will have to hit the back arrow ← at the top left on your computer to get back into this article. It is a little more trouble than before but I think NOAA scrapped the animation routine I was using so we have to keep up with “progress”.
The NWS Climate Prediction Center’s: Watches, Warnings, and Advisories plus other information can be found HERE. That takes you to the NWC Severe Weather Site. From there you can select among many categories of information. Remember to hit the back arrow ← at the top left of your screen to return to 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 will Resume in the Fall.
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.
