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.

…Heavy snow impacting the northern Rockies and northern High Plains to
spread into parts of the central Plains and Midwest tonight…

…Arctic air surging southward into the central United States this
weekend to produce potentially dangerous wind chills…

…Instances of heavy rain and flash flooding possible throughout the Gulf
Coast and Southeast on Sunday…

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.

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 main story over the next few days will be the arctic cold front slowly
traversing southward through the Great Plains and Intermountain West,
bringing plunging temperatures in its wake, including the chance for snow.
In the build-up to the surge of cold air, an initial system tracking
across the Great Lakes will continue to bring the chance for light to
moderate snow, especially along western-facing lake shores, where cold,
gusty northwesterly winds will produce lake-enhanced snow showers through
Friday evening. Further west, snow is expected to increase in intensity
throughout the Northern Rockies through Friday evening as the arctic
frontal boundary pushes southward from Canada into the region, producing
conditions favorable for moderate to heavy snow. Widespread Winter Storm
Warnings and Winter Weather Advisories have been issued for much of the
region due to the potential for a swath of accumulating snowfall
throughout lower elevations and totals exceeding 12" into the higher
terrain. The snow could be heavy at times and drastically reduce
visibility, making travel potentially treacherous.

Low pressure developing along the frontal boundary on Friday evening will
push into the central Plains, producing an axis of moderate snow on the
northern side of the low. A narrow swath of 4-6" is forecast from western
Nebraska into the Great Lakes through early Sunday, with higher amounts
possible across southeastern South Dakota and central Michigan. In
addition to the potential for snow, bitterly cold temperatures will
overspread much of the region as strong high pressure in western Canada
sends a surge of arctic southward behind the frontal boundary draped
across the Intermountain West and Plains. Temperatures 20 to 40 degrees
below average are forecast to spread into the northern Rockies and
northern/central Plains by Sunday, with highs only reaching into the
single digits and lows dropping into the minus teens. Gusty winds will
make it feel even colder and could lead to dangerous conditions for
individuals spending an extended amount of time outdoors.

As the arctic frontal boundary progresses southward into the southern
Plains, a northward surge of warm, moist air ahead of the system will
produce showers and thunderstorms across the Gulf Coast, with the
potential existing for heavy rainfall leading to flash flooding this
weekend. As a result, a Marginal Risk of Excessive Rainfall has been
issued for southeastern Texas and western Louisiana on Saturday, with the
threat expanding in severity and areal coverage on Sunday, as a Slight
Risk of Excessive Rainfall covers the entirety of the Gulf Coast.

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.
