It's that time of year!
In a previous post, Candice King mentioned how difficult it is to forecast the weather at this time of year because of our computer models' inability to keep up with the day-to-day changes in a transitional season. This is absolutely true! In the fall, the northern tier states cool more quickly than the southern states. This is largely because we lose daylight a lot quicker here than they do -- for example -- along the Gulf Coast. Our models have a difficult time keeping-up with this change.
Another thing you'll notice (which is related to the above topic) is that areas of low pressure will also become more powerful as we head into fall. A low pressure system's "job" is to draw warmer air northward and cooler air southward to equalize this imbalance. Since the imbalance gets bigger at this time of year, it takes a stronger low to "do the job." And a stronger low pressure system means windier days with bigger temperature swings from one day to the next. --TS
