Here is what we are paying attention to in the next 48 to 72 hours. The article also includes weather maps for longer-term outlooks and a five-day
World weather outlook.
We start with the U.S. Information. You can update this section here but these are 48 to 72-hour forecasts so if I have not been able to update this area twice daily, what is shown is still valid and the images in the body of the article update automatically but sometimes they are a bit slow to update.

…Cool and fair weather will persist across the northeastern quadrant of
the country as triple-digit heat continues across the southern half of the
Plains to the eastern Gulf Coast……Strong to severe thunderstorms are possible over the northern High
Plains into tonight as scattered showers and thunderstorms stretch across
the north-central Plains toward the Midwest……Monsoonal rainfall will become more widespread across the Desert
Southwest and into the Four Corners region while dry conditions persist
over the Pacific Northwest..
| Notices: Recently we published the NOAA Four-Season Outlook which you can access HERE. We recommend reading the full report as it is very important. Looking at the full article provides a more coherent view of the overall Four-Season Outlook. |
First, 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)

NEXT DAY

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.
Continuation of the NWS Short Range Forecast. It is updated by NWS twice a day and these updates can be found here
During the next couple of days, a broad upper-level trough will dominate
the weather pattern across the northeastern quadrant of the country. This
will keep a large dome of cool Canada in place across the entire area as
the cool air will continue to spread southward into the Carolinas behind a
well-defined cold front. The front is forecast to reach the Florida
Panhandle by Tuesday morning before becoming stationary, bringing some
less humid air down into the southern Atlantic states on Monday. On the
other hand, the cool air will not push as far south across the mid-section
of the country as triple-digit heat is forecast to continue over the
southern half of the Great Plains eastward to the eastern Gulf Coast. To
the north of the front, relatively cool and unsettled weather is expected
to prevail across the northern Plains toward the Midwest, where rounds of
thunderstorms can be expected especially over the northern High Plains for
the next couple of days and particularly this evening. Florida will
remain hot and humid with typical summer-time showers and thunderstorms.Over the southwestern portion of the country, increasing southerly flow
aloft is forecast to spread monsoonal moisture farther north from the
subtropics and Mexico as a high pressure cell aloft edges eastward into
the southern Plains. Showers and thunderstorms can be expected to become
more widespread across the Desert Southwest and into the Four Corners
region through the next couple of days. In addition, the rain will have a
tendency to spread farther north into the central to northern Rockies as
well as the nearby High Plains on Monday, and remain in these areas into
Tuesday. Meanwhile, dry conditions are forecast to persist over the
Pacific Northwest under the protection of an extension of the upper-level
high prior to the arrival of the next upper trough from the eastern North
Pacific. Temperatures will be warmer than normal over the Intermountain
region into the northern Rockies and the northern Plains but near or below
normal closer to the West Coast.

Below is the current five-day cumulative forecast of precipitation (Updates can be found HERE)
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.
| 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.
