Today Through the Fourth Friday (22 to 28 days) Weather Outlook for the U.S. and a Six-Day Forecast for the World: posted August 3, 2024

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.

...A dangerous heat wave shifts from the Paciifc Northwest to the Great
Plains...

...Stormy conditions and flash flood potential across portions of the
Eastern U.S. this weekend...

...Potential Tropical Cylone Four will bring hazardous rainfall, strong
winds and life threatening storm surge inundation to portions of Florida
this weekend...

Upper-level ridging over the West will promote above average temperatures
across the region this weekend. Upper troughing over the East Pacific will
work in combination with the Western ridge to produce high temperatures in
the upper 90s to low 100s across much of the Northwest into the
Northern/Central Plains today. Warm overnight lows in the upper 60s to low
70s will represent 20-30 degree anomalies for much of the Northern Great
Basin/Rockies/High Plains tonight. The lack of overnight relief from the
heat will affect anyone without effective cooling and/or adequate
hydration. A small bit of mid-level energy will contribute to a severe
thunderstorm threat over the Northern Plains and Upper Midwest this
afternoon/evening. Damaging winds, isolated Flash Flooding and hail will
be the primary threats there. Shortwave energy spinning across the
northern periphery of a mid-level closed high pressure bubble will bring
some scattered showers, thunderstorms and cooler temperatures to the
northern tier of the country beginning on Sunday. Meanwhile, warm air
shifts into the Central Plains and Middle Mississippi Valley through early
next week.

Elsewhere, upper troughing over the Ohio/Tennessee Valley will promote
scattered thunderstorms up and down the East Coast today. Slight Risks of
Excessive Rainfall and Severe Thunderstorms are in effect from the
Tri-State area down to the Florida Panhandle. Damaging wind gusts and
Flash Flooding will be the primary concerns from these storms. Some
lingering showers and thunderstorms are expected on Sunday with only an
isolated threat of severe storms and Flash Flooding across the coastal
Mid-Atlantic/Northeast.

Tropical Depression Four is forecast to strengthen into a Tropical Storm
as it tracks west of the Florida Peninsula this weekend. Heavy rainfall,
strong winds and life threatening storm surge inundation are all possible
along the western coast of the state beginning today. Heavy rainfall,
strong winds and storm surge are also possible over northern Florida and
the Southeast U.S. Coast Sunday evening into early next week. Tropical
Storm Warnings and Storm Surge Watches are in effect along Florida's Gulf
Coast while Tropical Storm Watches extend farther out across the other
Gulf Coast states. For more information go to hurricanes.gov.

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.

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.
