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.

Continuation of the NWS Short Range Forecast. It is updated by NWS twice a day and these updates can be found here
A winter storm will continue to push eastward from the Intermountain West
into the central Plains heading into the holiday weekend bringing a swath
of moderate to heavy snow. Snowfall is forecast from the eastern Great
Basin into the central Rockies and portions of the central High Plains,
particularly western Nebraska, on Friday, with the focus shifting into
Kansas Saturday. Snowfall totals of 4-6″ are forecast from western
Nebraska into western and central Kansas, with locally higher amounts
possible. A wintry mix will stretch from the Texas Panhandle northeast
through northern Oklahoma into eastern Kansas and Missouri, with some
light snow accumulations possible for the Texas and Oklahoma Panhandles.
Some heavier totals are forecast for the Wasatch and central Rockies,
particularly in southwest Colorado, where 12-18″ are expected. Gusty winds
and snow rates of 1″/hr at times will lead to hazardous travel conditions,
especially for portions of western and central Kansas on Saturday. The
snow should begin to taper off for the mountains by Saturday morning and
for the Central Plains by Saturday evening. Other than some showers and
thunderstorms from eastern Texas into the Lower Mississippi Valley on
Saturday, the rest of the country will be mostly dry.The other story this weekend will be below average temperatures for most
of the country following a cold front passage, with the greatest anomalies
and some frigid conditions in the central Plains. High temperatures Friday
and Saturday across much of the Central Plains will be in the 20s and 30s,
with morning lows dropping into the teens. Breezy winds will lead to
morning wind chills around and even below 0 in some cases. While not quite
as frigid, temperatures will also be running below average in the eastern
U.S., with highs in the 20s and 30s for the Great Lakes and Interior
Northeast, 30s and 40s for the Midwest and New England, and 40s and 50s
for the Mid-Atlantic into the Carolinas. The South will be warmer and
closer to average, with mostly 60s expected. Highs will be running below
average across much of the Interior West as well, with 30s and 40s for the
Northern/Central Rockies, Great Basin, and Four Corners Region, and into
the 60s for the Desert Southwest. Temperatures will be closer to average
for the West Coast, with highs in the 40s and 50s for the Pacific
Northwest/northern California and 60s into central and southern
California. However, morning lows will be a concern for the San Joaquin
Valley through the weekend as temperatures drop to near or below freezing.

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.
