weather Pattern Theory part 6

Above, you can see the forecast 500 mb pattern (approximately 18,000 feet) across North America. It goes hand in hand with our winter forecast. Kansas City is in northwest flow aloft. A deep trough is located through the Great Lakes with a ridge aloft in the west. This will bring us dry weather. One thing we must watch are these storm systems, or disturbances in the flow, that move over the ridge and then ride southeast through the plains. As winter approaches these systems can bring us some interesting weather changes.

We had our first snowflakes today, but the snowflake contest did not end. We must have one inch as measured by one of the NBC Action Weather Team's Meteorologists. So, the contest lives on.

Now, concerning the weather pattern theory.......remember we are likely going through our first cycle and once this cycle is complete then we will have much more confidence in what the weather pattern really is. This is why I will be making an adjustment to the winter forecast in December.
