How do these days 3-7 temperatures compare to average at this time of year?


Anomalies not very far from average. Coolest in the Plains to Midwest, Warmest West.

The top map is the Canadian ensemble average, the maps below are the individual members that make up the average


End of week 2....................0Z ensembles from Sunday.  The mean/average of all the members looks pretty zonal and mild with slight troughing over most of the country. Cold air from higher latitudes is cut off.  A lot of the members still have a deeper(southern stream) trough somewhere in the US.  Very few of them have northern stream energy or a cold air source, so it appears unlikely that mid November is going to shift to a much colder temperature regime.


++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Each member is like the parent, Canadian model operational model.......with a slight tweek/variation in parameters. Since we know the equations to represent the physics of the atmosphere in the models are not perfect, its useful to vary some of the equations that are uncertain(can make a difference) to see if it effects the outcome and how.

The average of all these variations(ensembles) often yields a better tool for forecasting. It's always more consistent. The individual operational model, like each individual ensemble member can vary greatly from run to run.........and represent an extreme end of the spectrum at times. The ensemble average of all the members, because it averages the extremes.............from opposite ends of the spectrum............changes much less from run to run.

Here are the 0Z GFS ensemble, individual solutions at 360 hours(2 weeks).

Overall, there is good agreement today on a mild, west to east or southwest to northeast flow. Potential upper level trough in West. Major cold air source is completely cut off. 

Better confidence at this time frame!

Latest, updated graph/forecast for AO and NAO here, including an explanation of how to interpret them. Both are predicted to be close to zero at the end of 2 weeks. This lessens the chance of cold air outbreak surprises vs if they were strongly negative..........but the AO and NAO are also forecasts and can be wrong at 2 weeks.

National Weather Service 6-10 day, 8-14 day outlooks.


Updated early this afternoon.  It should  be(high confidence) very wet across much of the country, especially the east. Temps should be warm in the East and chilly farther west.

These outlooks over the weekend are automated. The extensiveness of the area of warmth in the West is debatable in my opinion. I agree with the huge area of green(elevated chances for above precip in most locals).

 The GFS and Canadian models keep the major cold locked up, well to the north in Canada(northeast of the Hudson Bay).

However, the European model has a decent shot of strong cold early in week 2, noted on the map below this page.

The low skill, longer range CFS model for weeks 3-4.


Larry tells me that the source of this solution is a day old, so I am working on finding a source with the latest solution. Thank you WxFollower!

Widespread very mild conditions. Cold air is northeast of the Hudson Bay. 


Check in tomorrow to read something different............."low skill" (-:

`12z operational European model is colder than the other models early in week 2. The first map is 850 mb temps(around a mile above the surface) on day 10. Strong cold shot is hitting the Midwest and East at that time. Below that is the 500 mb solution. MUCH deeper upper level trough than the other models across most of the US which in combination with upper level ridging off the West Coast(and extending weakly into Northwest Canada,  is directing air masses  from much farther north(higher latitudes in Canada) to move southward across the US border.......a caravan of cold air invading without our authorization (-:

Look how much warmer the 18z operational GFS was for the same time frame:

Note the location of the blues on the 850 mb map(bottom right).............north of the border. The -10 deg. C isotherm on the European model above is almost to Chicago but on the GFS, its in Central Canada over 1,000 miles farther north, with very mild, zonal flow/west to east flow on the GFS. 

The GFS does not have the ridge in the West or the troughing across much of the US that the European model has early in week 2.
