If you read NWS discussions for the U.S. you can see they divided the continent into sections for their forecasts as seen in the feature graphic.
This is from the NOAA short range discussion for this week:
The short range period begins in a relatively quiet weather pattern across much of the lower 48 as sprawling surface high pressure dominates resulting in below average temperatures from nearly coast to coast. The greatest departures from normal on Tuesday will be from the Great Basin to the Midwest/Appalachians where afternoon highs of 10 to 20 degrees below early December normals are expected. This shifts into the Eastern states by Wednesday, with the Southwest and Central U.S. seeing a warm-up to near or slightly above average temperatures.
The surface high is located over Oklahoma and Kansas and as you can see there are no storm systems or low pressure systems anywhere in the U.S.. High- and low-pressure systems evolve due to interactions of temperature differentials in the atmosphere, temperature differences between the atmosphere and water within oceans and lakes, the influence of upper-level disturbances, as well as the amount of solar heating or radiationized cooling an area receives.
Pressure systems cause weather to be experienced locally. Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally associate with dry weather and mostly clear skies with larger diurnal temperature changes due to greater radiation at night and greater sunshine during the day.
Over the past few weeks we have seen our weather influenced by cold air moving in from Canada. Most of the storm systems have been moving through the Ohio Valley to the south of Michigan on up to New England. It is my thinking we will see this pattern change next week sometime as we get into a warmer pattern with a west to east flow influencing the weather across the northern plains and Michigan. I will get into this in my Thursday winter update post.
We may see some sun today which will be a welcome change before the clouds move back in and chances of lake effect snow increases for the lakeshore counties off and on through the rest of the week. Not expecting much as the air is dry due to the high pressure influence. Daytime temps will be at or below freezing with nighttime temps around 20 to the upper teens.
The below normal temps just keep coming! Another week of day after day of below normal temps! I love it!
The actual facts for the week are: Sunday was above average, Monday was exactly average, and today will prob come in below average. So that would be 1-1-1, all even.

Incredible stretch of WARMTH coming!!! Who knew?!??!
Looks like winter will be on vacation snow wise. I will take it. 🙂
Looks like our below average run will end soon!
I had the shades open on my office window, which faces ESE, for the past several weeks. I had to close them this morning because the sun was shining directly in my eyes and I was unable to see my monitors. It was a nice problem to have.
How many days till spring?
Only 86!! Not long at all.
Thanks
Actually real spring is like 105 days away. Still not too bad!

Sorry, just using meteorological Spring like everyone else does on here.
Lol! That is true Barry!
100% sun, no snow, and a dry/warm long-term forecast. Does it get any better than this?!
What a absolutely phenomenal day outside today! Clear this morning, saw Venus (now in the morning sky), the moon, and stars for the first time in over a month. Thanks to the bare and SNOW FREE ground, got all the oak leaves raked up that finally came down the past few days. Bright sun and calm winds, couldn’t ask for more! Looking like we could be keeping the ground SNOW FREE right through chrismas, sounds near perfect! Can we make a run at the December record for least amount of snow ever at 1 inch?
Per Dr Judah Cohen (AER)
Currently ridging/positive geopotential height anomalies and above normal temperatures dominate Alaska and Western Canada with toughing/negative geopotential height anomalies in Eastern Canada and much of the United States (US) with normal to below normal temperatures for most of the US and Eastern Canada. However, starting next week, the ridging now in Western Canada will spread southeastwards with expanding above normal temperatures across the continent. One exception will be Alaska where increasing troughing/negative geopotential height anomalies will bring below normal temperatures.
Per Woodtv:
LATE WEEK/WEEKEND Sunshine is expected through the weekend! It will still be colder than average by almost 10 degrees with highs near 30.
LOOKING AHEAD Disappointing news for “snow-lovers”, as a milder stretch of weather appears to be on the horizon for much of next week.
