Today Through the Fourth Friday (22 to 28 days) Weather Outlook for the U.S. and a Six-Day Forecast for the World: posted June 19, 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.

…Significant heavy rain/flash flooding threat with gusty winds well
ahead of Potential T.C. One expected to impact southern Texas today…

…A heat wave will persist over the Midwest, Great Lakes, Ohio Valley and
the Northeast into late week…

…Thunderstorms and heavy rain become less active across the
north-central today into Thursday but may reload across the northern
Plains Thursday night/early Friday…

With the last piece of the potent upper-level energy exiting into southern
Canada, the weather across the northern tier states will be less busy than
recent days. Meanwhile, Potential Tropical Cyclone One (PTC1) is making a
headline as the heavy rain and tropical-storm-force winds well north of
the center of circulation are poised to move onshore and head inland
across southern Texas today. It appears that the lower and middle Texas
coasts will be the locations that will most likely be impacted by the
heavy rain and gale force winds. A coastal front may enhance the heavy
rainfall just inland from the coast but how sharp this front will get
is uncertain at this point. Meanwhile, the strong Bermuda High that will
help sustain the heat wave across the Ohio Valley to the Northeast will
also help steer PTC1 westward toward northern Mexico today as PTC1 could
acquire tropical storm (TS) status before making landfall early on
Thursday. The heavy rain well north of TS1 will likewise move west across
southern Texas and into the Rio Grand Valley through tonight, resulting in
rainfall totals of 5 to 10 inches from northeast Mexico into South Texas
with maximum totals of 15 inches possible. Winds associated with TS1 will
weaken rapidly over northern Mexico as the heaviest rainfall is forecast
to move west of the Rio Grand Valley into northern Mexico and begin to
taper off early on Friday. Meanwhile, some of the tropical moisture from
TS1 is forecast to stream north and trigger showers and thunderstorms
across the Four Corners region by Thursday and into Friday.

As the aforementioned upper-level energy and associated low pressure
system moves farther into Canada, the thunderstorms and heavy rain from
the central Plains to the upper Midwest will become less active today.
The trailing front from the low will become nearly stationary from west to
east across the northern tier states during the next couple of days. The
next piece of upper-level energy ejecting from the central Rockies will
begin to interact with the stationary front late on Thursday and
reinvigorate heavy rain and strong thunderstorms across the northern
Plains and toward the upper Midwest into Friday morning.

Meanwhile, a heat wave will continue to impact areas from the Midwest into
much of the Ohio Valley, Great Lakes, Northeast and Mid-Atlantic through
the next few days. Afternoon high temperatures and warm overnight lows
will likely challenge daily records and even some monthly records. Heat
index readings are expected to peak from 100 to 105 degrees in many
locations. Those without access to reliable air conditioning are urged to
find a way to cool down. Record warm overnight temperatures will prevent
natural cooling and allow the heat danger to build over time indoors
without air conditioning. Conditions are expected to improve over New
England this weekend.

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.

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.

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.

 I hope you found this article interesting and useful.
