We flipped the calendar today from September into October, a transition that is just one day, but typically signifies at least a mental transition to cooler days. The pattern across the U.S. will be anything but Fall-like however, with a deep west coast trough developing, and a strong upper-level ridge in the east. The upper-level pattern today through this weekend will result in upper 80s and low 90s in the Commonwealth.
The dip you see across the Central Plains this weekend will shift eastward, bringing a good chance for rain early next week. Thunderstorms will be very likely in Virginia based on the amount of heat and moisture in place. The cool air associated with this system will only give us a glancing blow, so I expect 80s to continue well into next week. -Zach
