Short Term and Intermediate-Term Weather Outlooks for the U.S. and a Six-Day Forecast for the World: posted November 16, 2023

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 six-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.

…Heavy rainfall and threat for flash flooding across the eastern Florida
Peninsula today…

…Wet/unsettled weather for California through the rest of the week…

…Another mild day for the Midwest/Great Lakes today with high
temperatures 15 to 25 degrees above average…

Notices: We recently published a review of October weather worldwide and you can access that article HERE. And a review of October weather for the U.S. which you can access HERE. Soon we will publish the NOAA Seasonal Update.

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

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

An area of low pressure along a frontal boundary draped just south of
Florida and a ridge of high pressure over the western Atlantic will help
to maintain a moderate fetch of low level easterly flow into the
southeastern U.S., including Florida today. Anomalous moisture wrapping
around the surface low near Florida and coastal convergence will support
the threat for locally heavy rainfall today and tonight, with potential
for spot rainfall maxima over 5 inches through Friday morning. However,
the threat for the heaviest rainfall looks to be confined to the
southeastern coast early, translating northward during the afternoon and
into tonight before pushing offshore for Friday. Gusty winds up to 40 mph
will also be possible along the eastern Peninsula today due to an
increased pressure gradient between the surface low and high pressure to
the north.

Across the West Coast, a slow moving closed upper level low will keep rain
in the forecast for portions of California through Saturday morning,
including a threat for thunderstorms for the central coast of the Golden
State. While rainfall may be heavy at times, rainfall totals are not
expected to be hazardous with generally 1-2 inches expected through
Saturday morning. Light accumulations of snowfall are anticipated for the
higher elevations of the Sierra Nevada as the storm system moves east on
Friday.

Across the Intermountain West to the Great Plains, Great Lakes, Midwest
and East Coast, mild weather will be in store for today with temperatures
above mid-November averages. In fact, parts of the Midwest and Great Lakes
will see high temperatures well into the 60s today which is 15 to 25
degrees above average. A cold front and associated rainfall will bring
temperatures closer to average for Friday into Saturday for the central to
eastern U.S. but mild conditions will remain for much of the remainder of
the country.

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.
