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 forecast.
We start with the U.S. Information.

…Below average temperatures for large portions of the nation to the east
of the Rockies, while above average temperatures expand across the West……Heavy rains, isolated flash flooding and severe weather possible across
portions of the Central to Southern Plains……Elevated to Critical Fire weather conditions to persist across the
Southern High Plains…
| Information Note: This article is now set up so that all the maps should automatically update. The links are provided but should not be needed. The downside is that if you go back to a previous version the maps will have been updated and not be relevant to the date of the prior article but will be current information. The NWS twice-a-day 48-hour forecasts do not auto-update in this article. I do it and I can be late doing it. The link for the NWS updates is HERE. Most of our other articles will not be set up to auto-update so that prior versions of the article will be meaningful.
Recent;y, we published the NOAA Seasonal Outlook which I call a Four-Season Outlook. You can access it HERE. Remember the easiest way to get back to the article you were reading is to hit the return arrow in the upper left of your screen. There are other ways. |
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)
TOMORROW
NEXT DAY
This animation shows how things may play out over the next 60 hours. To update click here.
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. We post at least one of those updates daily, sometimes both. The Highlights are shown in the lede paragraph of this article.
A cool spring weather pattern on tap for the next few days for most areas
to the east of the Rockies. A broad mid to upper level trof will remain
entrenched across much of the central to eastern half of the nation,
supporting below average temperature over the next few days for most areas
to the east of the Rockies. High temperatures are expected to be 5 to 15
degrees below average across these regions. A small region across the
Central to Southern Plains will see high temperatures as much as 20 to 25
degrees below average over the next few days. This will be associated
with an area of potentially heavy rains that spread east southeastward
across portions of the Central to Southern Plains from southeast Colorado,
western and southern Kansas, all of Oklahoma and northern Texas. These
heavy rains may lead to isolate areas of flash flooding across these
regions. Severe weather is also possible with this area of heavy rains,
especially along the southern edge of the heavy precipitation region
across northern and central portions of Texas.Farther to the south and west across the Southern High Plains, dry
conditions are expected to persist over the next several days. These dry
conditions, combined with low relative humidities and gusty winds will
keep the fire weather threat at an elevated to critical level over the
next few days across large portions of New Mexico, far southeastern
Arizona and southwest Texas. Fire Weather watches are currently in effect
across these regions.The cool spring weather pattern will also support potential for widespread
frosts and freezes early Tuesday morning across the Upper Ohio Valley, the
Southern to Central Appalachians and portions of the Mid-Atlantic. Freeze
warnings and frost advisories are currently in effect for these regions.
Morning temperatures will also likely fall to below freezing levels both
Tuesday and Wednesday mornings from the Northern Plains, into the Upper
Mississippi Valley and Upper Lakes regions.While below average temperatures grip much of the central to eastern U.S.
early this week, above average temperatures will be expanding across much
of the western U.S. This much above average temperature pattern will
likely continue through the remainder of the week with a gradual increase
in temperatures each day. This may lead to some record high temperature
potential for portions of northern California, western Oregon and western
Washington State toward the end of the work week.
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.

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.
