Here we are entering the holiday season and it feels more like October. Arizona along with much of the West is experiencing some of the driest and warmest fall weather in record keeping history, in some cases that's nearly 120 years!

This may seam like a familiar forecast, that has become much more common in recent years. The dry and warm conditions that come with high pressure has become of much concern for many throughout the western United States. Recently many atmospheric scientists are conducting research into this relatively new "Ridiculously Resilient Ridge" phenomenon.
