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 five-day World weather forecast.
We start with the U.S. Information.

Mississippi Valley and Upper Great Lakes……Snow over the higher elevations over the West…

| Information Note: This article is now set up so that all the maps should automatically update. The links are provided but should not be needed. The downside is that if you go back to a previous version the maps will have been updated and not be relevant to the date of the prior article but will be current information. The NWS twice-a-day 48-hour forecasts do not auto-update in this article. I do it and I can be late doing it. The link for the NWS updates is HERE. Most of our other articles will not be set up to auto-update so that prior versions of the article will be meaningful.

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
TODAY (or late in the day the evening/overnight map will appear)
TOMORROW
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.
Low pressure and an associated front over the Central Plains will move
eastward off the Mid-Atlantic Coast by early Tuesday. The system will
create an area of rain and heavy snow over parts of the Upper Mississippi
Valley/Upper Great Lakes on Sunday evening into Monday morning. Along the
rain/snow line, rain/freezing rain pockets will develop over the region.
On Monday, rain and snow will continue over the Great Lakes and Ohio
Valley, with the rain and snow moving into parts of the Mid-Atlantic by
Monday evening into Tuesday. Likewise, there will be a region of
rain/freezing rain along the rain/snow line over the Mid-Atlantic. On
Tuesday, light snow showers will continue over parts of the Northeast. The
combination of snow and ice may cause hazardous road conditions.Meanwhile, an area of upper-level energy will move onshore over the
Pacific Northwest and slowly expand eastward to the Northern Plains by
Tuesday evening. The upper-level energy and associated weak onshore flow
will produce coastal rain and higher-elevation snow over Pacific Northwest
and California through Tuesday afternoon. In addition, snow will develop
over parts of the Northern Intermountain Region, Great Basin, and
Northern/Central Rockies through Tuesday. By Monday, the upper-level
energy will create light snow over parts of the Northern/Central Plains
Sunday evening into Tuesday evening. The snow will result in reduced
visibility and hazardous driving conditions.Furthermore, multiple areas of low pressure will move along a stationary
front extending from the Southwest to the Southern High Plains through
Tuesday. As a result, the SPC has issued an Elevated and Critical Risk of
fire weather over the Southern High Plains from Sunday into Tuesday.
Strong wind, low humidity, and dry fuels have contributed to the areas of
Elevated and Critical Risk of fire weather.
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.

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.
