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
Tue Jun 11 2024
Valid 12Z Tue Jun 11 2024 – 12Z Thu Jun 13 2024…There is a Slight Risk of severe thunderstorms over parts of the
Southern Plains on Tuesday and over parts of the Upper Mississippi Valley
on Wednesday……There is a Slight Risk of excessive rainfall over parts of the southern
tip of Florida through Wednesday……There are Excessive Heat Warnings/Watches and Heat Advisories over
Northern/Central California, Southwest, and western Texas on Tuesday…A front extending from the Southeast across the Gulf Coast into the
Southern Plains will make the eastern portion quasi-stationary over the
Southeast. At the same time, the western half dissipates on Wednesday. The
half of the west of the boundary will aid in creating showers and severe
thunderstorms over parts of south-central Texas. Therefore, the SPC has
issued a Slight Risk (level 2/5) of severe thunderstorms over parts of the
Southern Plains through Wednesday morning. The hazards associated with
these thunderstorms are frequent lightning, severe thunderstorm wind
gusts, hail, and a minimal threat of tornadoes.Furthermore, showers and thunderstorms will develop along the eastern
portion of the front. The combination of 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 Slight
Risk (level 2/4) of excessive rainfall on Wednesday morning. The
associated heavy rain will create mainly localized areas of flash
flooding, with urban areas, roads, small streams, and low-lying areas the
most vulnerable. Also, showers and thunderstorms will develop along parts
of the Mid-Atlantic Coast.In addition, the tropical moisture will continue to produce showers and
thunderstorms with heavy rain over parts of southern Florida. Therefore,
the WPC has issued a Slight Risk (level 2/4) of excessive rainfall from
Wednesday into Thursday morning. The associated heavy rain will create
mainly localized areas of flash flooding, with urban areas, roads, small
streams, and low-lying areas the most vulnerable.Meanwhile, an upper-level low over the Northeast will help develop rain
with daytime-embedded thunderstorms over the area on Tuesday and Wednesday.Elsewhere, another front over the Upper Mississippi Valley extending
southwestward to the Central Rockies/Great Basin will move eastward to the
Great Lakes and dissipate by Wednesday evening. On Tuesday, the front will
produce showers and thunderstorms over parts of the Upper Mississippi
Valley/Upper Great Lakes into the Central Plains and Central Rockies.On Wednesday, moisture pooling along the boundary will create showers and
severe thunderstorms over parts of the Upper Mississippi Valley.
Therefore, the SPC has issued a Slight Risk (level 2/5) of severe
thunderstorms over parts of the Upper Mississippi Valley from Wednesday
through Thursday morning. The hazards associated with these thunderstorms
are frequent lightning, severe thunderstorm wind gusts, hail, and a few
tornadoes. Moreover, there will be an added threat of hail, two inches or
greater, over the region. Further, showers and thunderstorms will develop
from the Gulf Coast to the Southern High Plains on Wednesday.Furthermore, upper-level ridging will build over California and the
Southwest on Tuesday, and a subtropical high will develop over
North-Central Mexico, prompting Excessive Heat Warnings and Advisories
over Northern/Central California and Southwest and Excessive Heat Watches
in western Texas. Residents and individuals involved in outdoor activities
must stay informed and take necessary precautions.

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.
