This article focuses on what we are paying attention to in the next 48 to 72 hours. The article also includes weather maps for longer-term U.S. outlooks and a six-day World weather outlook which can be very useful for travelers.
First the highlights from the NWS.

Continuation of the NWS Short Range Forecast. It is updated by NWS twice a day and these updates can be found here
Our very busy weather pattern continues this weekend as an intense low
pressure system yields significant wintry weather across the Corn Belt and
Great Lakes today, with frigid Arctic air on its heels spilling southward
from Canada. As of this morning, surface observations and radar depict
moderate to locally heavy snowfall and gusty winds across portions of the
Heartland as intense low pressure lifts into the Great Lakes. Bouts of
snowfall on the back side of this expansive low, combined with wind gusts
upwards of 25-40 mph will maintain blizzard conditions and dangerous to
impossible travel across parts of the Corn Belt through the Great Lakes
today even as the overall snowfall area associated with this system
diminishes by later on this evening. As the system lifts into Canada this
afternoon, cold northwesterly flow will rev-up the lake effect snow
machine downwind of the Great Lakes, where an additional 12-24 inches of
snowfall can be expected where lake effect snow bands focus across much of
western Michigan into New York state through midweek. Meanwhile, in the
warm sector of this system heavy rainfall is streaming into the Northeast,
which may result in scattered instances of flooding through this morning
as much of the region is soaked in light of recent heavy rainfall. Coastal
areas across portions of the Mid-Atlantic and Northeast can also expect to
see moderate to isolated major coastal flooding today, with significant
impacts.The weather story is equally busy for the western half of the U.S. as the
aforementioned Arctic airmass presses further south and west. Low
temperatures approaching 40-50 below zero are not out of the question this
morning over parts of Montana in the heart of the cold air, and numerous
sub-zero low temperature records could fall today and tomorrow over the
Northern and Central Plains. Including wind chill, temperatures will fall
below minus 30 over a large area running from the northern Rockies to
northern Kansas, with minus 50 possible across the Dakotas. Further west,
heavy blowing snow and valley icing will all contribute to hazardous
travel across the Great Basin and Pacific Northwest this weekend, where a
swath of Winter Storm Warnings and Watches is in effect. Significant
freezing rain is expected over Oregon today, with tree and power line
damage possible. The cold air migrating south is expected to usher in
wintry precipitation over the Mid South by the end of Sunday, with areas
of snow, sleet, and freezing rain likely to develop across the ArkLaTex.
As we begin the work week, several inches of snow are possible across
these areas. Unfortunately, hazardous cold weather looks to stick around
going into next week, with dangerously low temperatures and wind chills
persisting through at least midweek.Scattered flash flooding also remains a threat today across portions of
northern coastal California and Oregon with strong low pressure lingering
offshore. Periods of excessive rainfall rates will support rainfall totals
of 3-5 inches through today, where a Slight Risk of Excessive Rainfall is
in effect.

Ski SnowReports
New Feature – Ski Reports. It is difficult to find reports that auto-update on-screen (and they are very long) but these links will get you to them – If you have additional suggestions make them in the comments section after every Econcurrents Article and we may add those links. We will try to not have too much overlap as that can add to the confusion.
Snow Forecasts. And remember this shows natural snow. Ski resorts also make their own snow.
Day 1
Day 2
Additional snow information can be found here and here. The second link provides animations.
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.

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.
