December 4, 2022

Sunday Morning Update 

The colder air is back in place, but this is not the pattern change yet. It is seasonable to have cold shots and warm-ups ahead of a full pattern shift, which we are expecting over the next week or two. We will get a few days with rain and mild air during the week, then open the door to colder air.  If your app is NOT showing colder air or wintry mix next weekend, there is a simple answer for that.

I do NOT lock in on a promise for any winter event a week away, but the signal is there trying for something.  So please use your discretion with all the information you encounter. Here is a simplified look:

 

Headlines

  • Today: Sunny and Cold!
  • Mid Week: A Few Days With Rain, Warmer
  • Next Weekend: Pattern Change: ‘Maybe’ Wintry Mix?

 

Morning Temperatures

Seasonably cold morning, but the sun is shining.

December 4 weather temperatures Sunday morning

 

Morning Surface Weather

High Pressure has brought in this cold air mass.  The next storm is forming in the Southwest US, which will be part of the pattern change.  This is what we will watch bring us more clouds Monday and then a period of rain (on/off) Tuesday through Friday.

Afternoon Temperatures 

It will be cold, but the winds will settle down. 

 

Afternoon Wind Chill

Any breeze will make it feel chillier.

Rain Mid-Week

ECMWF Model: Tuesday to Saturday Morning.

Progressive waves of rain almost each day.

Friday Night/Saturday: Colder air may catch up and end with snow….

If your weather app is NOT showing this, here is why:

Model Comparison: Early Saturday Morning

  • The ECMWF Models is colder than the GFS
  • The difference of the storm track and snow. Most Apps use the America GFS Model.  
  • It has a history of being less accurate than the European ECMWF.
  • While a lot can change in the next 6 days, this is worth paying attention to for trends and which model has a better handle.

 

 

GFS Model Simulation

Here we see the storm track to the north and NOT bringing in the colder air.

Jet Stream:

Mild temps will come with the initial rain mid week. However, this is the start of the change that shows a progressive opening of the arctic air to spill into the US next weekend and the week that follows. 

December 4 jet stream colder Thursday Tuesday

 

7 Day Forecast

After the rain, it will be chilly for the Ravens game. Then mild again next week with rain ahead of the pattern change.

There is rumbling about next weekend turning wintry. I will have a look at that in my next report.
