Weather Forecast: Today, Tonight, Tomorrow, Next Day, Five Days, for the U.S. and the World with links for longer-term forecasts: posted February 4, 2023

Updated at 9:40 p.m. EST Saturday, February 4, 2023

Here is what we are paying attention to in the next 48 to 72 hours. This article also includes World weather forecasts.

It also includes links for longer-term outlooks and sometimes (like today) we show the maps that one finds if one clicks on those links. But we can not update all of those maps each day so look at the date and the duration of the period of time involved. If you want a more up-to-date map, click on the provided link which may be located in a table of links. If the date in the title of the article is not today’s date. just go to Econcurrents.com and look for today’s weather article.

We start with the U.S. Information.

…Frontal system moving through the West brings increased chances of
lower elevation/coastal rain and moderate to heavy mountain snow…

…Rapid warm up Sunday for the Northeast after record-breaking arctic
blast…

…Unseasonably warm temperatures for the Plains and Midwest with an
Elevated Risk for Fire Weather in the Southern High Plains Sunday…

Here is the NOAA forecast for February and the three-month period February, March, April

Here is another forecast by another meteorological agency JAMSTEC. It is a forecast for the single month of March. It is a World forecast but you can see the forecast for the U.S. in these two maps: Temperature and Precipitation.

Now, the 48-Hour Forecast (It is a 48 to 72 Hour Forecast actually)

Daily weather maps. I try to keep the below three maps updated. The Day 1 map updates twice a day and the Day 2 and 3 maps update only once a day. I will be doing the updating during the period described in the title of the article but if you happen to read this article later, you can get updates by clicking HERE.

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 deep upper-level trough and associated frontal system over the Pacific
will begin to move eastward over the western U.S. late Saturday. Increased
moisture from the Pacific will lead to the chance for some moderate to
heavy rain along the West Coast Sunday, especially for the northern and
central California coast where rainfall totals of 1-2″ are forecast. This
moisture will spread further inland bringing moderate to heavy snow to the
Cascades, Sierra, and mountain ranges of the northern Great Basin Sunday
before spreading into portions of the northern and central Rockies on
Monday. Snowfall totals will range between 6-12″, with locally higher
amounts of 18″+ possible for some of the higher mountain peaks. Totals
will be even higher in the Sierra, where Winter Storm Warnings are in
effect for 1-3 feet of snow and gusty winds as high as 60 mph. Lower
elevation/valley locations of the Great Basin and northern/central Rockies
will see a mix of rain and snow, with little to no accumulations expected.
High temperatures will cool following the passage of a cold front, with
highs mostly in the 50s to low 60s for the Pacific Northwest and
California on Sunday, and highs in the 30s for the Great Basin and upper
50s to the mid-60s for the Desert Southwest on Monday.

Temperatures will rapidly moderate across the Northeast on Sunday after a
couple days of record lows and historicly cold wind chill values. The dip
in the jet stream responsible for sending a surge of arctic air southward
will move east of the area with southerly winds advecting warmer air from
the south northward. Lows will still be rather chilly Sunday morning for
portions of New England, with temperatures around 0, but temperatures will
warm back up above freezing for most locations by the afternoon. Highs
further south in the Mid-Atlantic will be in the 40s to low 50s, with 50s
to low 60s for the Southeast. These seasonably warm temperatures will
continue into Monday, with most of New England also warming up into the
40s. Some light rain showers will be possible along the coast for the
Southeast Sunday and into the Mid-Atlantic Monday. Additionally, some
light snow showers are possible in the Interior Northeast, particularly in
favorable lake-effect areas. A frontal boundary meandering over the
Florida Peninsula will lead to increased chances for showers and
thunderstorms, with heavy rainfall possible along the Atlantic coast late
Sunday and into the day Monday.

Ahead of the upper-level trough over the west, a ridge will move over the
center of the country and lead to temperatures 15-25 degrees above normal
across large portions of the Plains and Midwest. Highs will be in the 30s
and 40s for the Northern Plains and Great Lakes Region, the 50s and 60s
for the Central Plains, Ohio Valley, and Lower Mississippi Valley, and
into the 70s for portions of the Southern Plains. Breezy winds between
15-25 mph, with higher gusts, will be prevalent along the High Plains as
lee troughing develops east of the Rockies. These gusty winds along with
the warm temperatures, low relative humidity, and dry vegetation have
prompted an Elevated Risk of Fire Weather from the Storm Prediction Center
Sunday for portions of northeastern New Mexico and the western Oklahoma
and Texas Panhandles.

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.
