Weather: Tonight, Tomorrow, Next Day, Five Days, and Intermediate-Term Outlooks for the U.S. and a Six-Day Forecast for the World: posted May 29, 2023

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

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.

The large scale flow across the Lower 48 remains fairly blocked over the
next few days, characterized by a mean trof across the western half of the
country, another trof from the southern Mid-Atlantic into the Southeast
and a closed upper high from the Great Lakes into the Northeast.

The mean trof pattern across the western U.S. will support widespread
scattered showers over the next two days from northern California through
the northern Great Basin, Northern Rockies and across much of the Plains
states. Across these regions, isolated heavy rainfall amounts are
possible along with isolated instances of flash flooding.

Across the Southern Mid-Atlantic, a slow moving upper low will inch its
way offshore during Tuesday. This system will continue to produce
scattered showers across the Southern Mid-Atlantic on Tuesday, but as the
system continues to push offshore, drier conditions expected on Wednesday.
In the wake of this upper low moving offshore, another upper low is
expected to form across the central Gulf of Mexico. Shower activity will
become increasingly likely to the east of this developing upper low on
Wednesday, bringing increasing rain chances for central to South Florida.
This new upper low will be slow moving through the remainder of the week
as it moves across the eastern Gulf and Florida, maintaining a wet pattern
for central to South Florida into late this week.

A closed upper high will remain parked across the northeastern portion of
the nation from the Great Lakes into New England. Dry conditions and much
above average temperatures will accompany this upper high with high
temperatures 15 to 20 degrees above average across much of the northern
tier from the Norther Plains, through the Upper Lakes, northern NY State
into Northern New England. Cooler than average temperatures over the next
few days will be associated with the showery pattern across the
southeastern U.S. and along the West coast into the Desert Southwest.

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.

6 – 10
8 – 14
3 – 4

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.
