Today Through the Fourth Friday (22 to 28 days) Weather Outlook for the U.S. and a Six-Day Forecast for the World: posted April 14, 2024

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.

…Severe thunderstorms possible over interior portions of the Northeast
on Sunday…

…Lingering locally heavy showers and moderate to heavy snow in
California Sunday…

…Intensifying storm system over the Plains to bring the threat of severe
weather Monday…

…Well above average temperatures across the central/eastern U.S;
Critical Risk of Fire Weather for the central/southern High Plains
Monday….

An upper-level shortwave/surface frontal system dropping southeast through
the Great Lakes into the Upper Ohio Valley/Interior Northeast Sunday will
bring a renewed chance for showers and thunderstorms. Strong wind fields
overlapping a southward moving cold front from central Ohio east into
Pennsylvania will lead to some supercell structures and potentially a
developing line of more intense thunderstorms. The Storm Prediction Center
has issued an Enhanced Risk of Severe Weather (level 3/5) for the threat
of some damaging wind gusts with these storms, along with a few instances
of large hail and perhaps a tornado or two. Some locally heavy downpours
will also be possible, and wet antecedent conditions through the terrain
of the Appalachians could lead to an isolated risk of some flash flooding
across this region as well. Storm chances should quickly diminish
overnight Monday as the frontal system pushes southeastward off the East
Coast.

A deep upper-level low and associated surface frontal system over the West
will continue to progress eastward during the day Sunday. A few areas of
heightened precipitation will continue under the influence of the low,
particularly for portions of southern Oregon/northern California and
southern California. Moderate to locally heavy lower elevation
coastal/valley rain showers, including some thunderstorms, are expected.
Moist onshore/upslope flow along the Transverse Ranges of southern
California may lead to a couple inches of rain on top of wet antecedent
soils from Saturday’s rainfall, with an isolated threat for flooding.
Higher elevation mountain snow will also continue in California, with a
few more inches of accumulations forecast for the Sierra Nevada.
Precipiation chances will spread further inland with the system with some
lower elevation valley rain and higher elevation snow possible for the
northern Rockies and central Great Basin Sunday evening, continuing into
Monday for the Great Basin and spreading into the central Rockies. Some
moderate snow accumulations will be possible for the higher mountain
elevations here as well.

As the system spreads into the Plains, lee cyclogenesis will help to
deepen the surface low pressure system, with intensifying moist southerly
flow from the Gulf leading to widespread shower and thunderstorm
development by Monday evening. This will be most likely for upslope
portions of the northern/central High Plains northwest of the low, along
the arcing cold front south across the central/southern Plains, and
eastward along a warm front into the Middle Mississippi Valley. Strong
buoyancy and strengthening low to upper-level flow will lead to the threat
of severe thunderstorms. The Storm Prediction Center has outlined a broad
Slight Risk of Severe Weather (level 2/5) across the central/Southern
Plains for the threat of large hail, damaging winds, and a few tornadoes.
An Enhanced Risk (level 3/5) has been included over western
Oklahoma/northwest Texas where a locally higher risk for very large hail
exists. While storms will tend to be rather progressive, especially with
southern extent along the cold front, the influx of higher moisture may be
enough for some locally heavier downpours and an attendant isolated risk
for flash flooding. The storms will continue to progress eastward into the
Midwest and Mississippi Valley overnight Monday and into the day Tuesday,
just beyond the current forecast period.

A broad area of well above average temperatures will continue across the
central/eastern U.S. Sunday and Monday as ridging leads the approaching
system over the West. Highs from the central/southern Plains through the
Mississippi Valley and into the Mid-Atlantic/Southeast will be into the
80s. Some 90s will even be possible Sunday over the central/southern High
Plains. Unfortunately, strengthening winds with the intensifying system
over the Plains on top of dry conditions behind a surface dryline through
the central/southern Plains has prompted a Critical Risk of Fire Weather
(level 2/3) from the Storm Prediction Center for portions of the
central/southern High Plains Monday. Conditions will also be warm along
the northern tier as well, with 60s and 70s from the Northern Plains to
the Great Lakes. Cooler temperatures will prevail over most of the West
under the influence of the upper-low and following cold frontal passage,
with 50s and 60s over California Sunday spreading further into the Great
Basin Monday. Highs in the Desert Southwest will generally be in the 70s.
Warmer temperatures will arc northwest into the Pacific Northwest/Northern
Rockies Sunday, with highs in the 60s and 70s, though cooler temperatures
will also follow here Monday.

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.

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.

HAZARDS OUTLOOKS

Click here for the latest complete Day 3 -7 Hazards forecast which updates only on weekdays.  Once a week probably Monday or Tuesday I will update the images. I provided the link for readers to get daily updates on weekdays. Use your own judgment to decide if you need to update these images. I update almost all the images Friday Night for the weekend edition of this Weather Report.  So normally readers do not need to update these images but if the weather is changing quickly you may want to.

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.

 I hope you found this article interesting and useful.
