Climate Prediction Center 6 to 10 day forecast from December 2nd to December 6th.

Warmer Weekend Coming

The new 6 to 10 day forecast for December 2nd through December 6th has warmer than normal temperatures forecast through early next week. There is greater than a 50% chance on this particular graphical forecast.

European Forecast “Model” 7 pm Saturday

This forecast model shows the warm up to confirm the temperatures shown on the Climate Prediction Center’s graphical forecast for warmer than normal temperatures. You can see the flow is coming in from the southwest and the 500 millibar thickness lines (dotted lines) are being pushed toward the north. That tells me that it will be very warm with a flow coming in from the southwest.

Colder Air Returns

Colder air returns by Wednesday of next week

This is the European forecast model for next Tuesday. You can see the cold air is starting to build in the west as the ’540′ line is pushed south. This is the freezing line and we should see a dramatic change in temperatures by the middle of next week.
