It’s not the end of the world I’m thinking about, or even the debt limit, but it’s how all these sunny days finally end. We can thank high pressure, both on the surface and above us in the atmosphere for our present weather. While all of us can enjoy the sun, this weather is not very interesting to meteorologists, unless you find fascinating potential deteriorating air quality and warmer temperatures
What is more interesting is how this “nice” weather will resolve itself. Because of the high pressure warm air is shunted northward to the west of us and cold air is shunted southward to the east of us and we are in the calm between these two flows. However, this is a strong weather pattern in place with serious weather on either side of us. When this type of weather pattern changes (and it always does) it could: go out with a whimper where the pattern gradually changes to more wet and stormy, or go out with a bang where the high pressure moves westward, and puts us in the cold airflow from the north. Such patterns can bring heavy snow and strong north winds.
So far the computer forecast models out to 8 days are not even giving a hint as to what the end will be besides keeping the pattern constant.
