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 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.

again late Friday across the Upper Lakes…

…Arctic air to surge south into the Northern Plains/Upper Mississippi
Valley on Friday…

First, 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.

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 strong storm that has produced a broad band of heavy snow from
portions of the Southern Plain, into the Middle Mississippi Valley and Mid
West region  over the past 24 hours will continue to press northeastward
Wednesday evening into Thursday from the eastern Great Lakes and across
New England.  Heavy snows are possible ahead of this storm across portions
of the eastern Great Lakes, northern New York State into Northern New
England where winter storm warnings and winter weather advisories are
currently in effect.  To the south of the snow areas, heavy rains are
expected to push across the coastal Mid-Atlantic into southeast New
England from this evening into the early hours of Thursday,  including the
New York City to Boston urban corridor.  These rains may produce isolated
runoff issues, especially in more urbanized regions.  Farther south along
the east coast, rains will come to an end by midnight as a strong cold
front pushes offshore.  This front will be pressing southward through
Florida Wednesday night, bringing much cooler temperatures for Thursday
and Friday,replacing summer like readings in the 80s with below average
temperatures.  In the wake of the strong northeast storm  pulling away
from New England on Thursday, west northwesterly flow across the Great
Lakes will support active lake effect snow showers downwind of all of the
Great Lakes into the upslope of the Central to Southern Appalachians, with
locally heavy snowfall accumulations likely.

Much of the remainder of the nation will be fairly tranquil weather wise
on Thursday. Some light snows are possible, however, from the Northern
Rockies into the Northern Plains on Thursday. An arctic frontal boundary
is expected to sink southward on Friday across the north central portions
of the nation, bringing much below average temperatures for the Northern
Plains into the Upper Mississippi Valley by the end of the week into this
weekend.  This arctic front will also support the potential for heavy
snows across the Northern Rockies through much of Friday.  Lake effect
snows also likely to begin late in the day on Friday downwind of the Upper
Great Lakes as the arctic front sweeps eastward through the Great Lakes
region on Friday.

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.
