Warm Start To DecemberNovember 27th, 2012 at 12:03 pm by Greg Shoup under Weather
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.
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
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.
