Yesterday brought the first rainfall of October for Bowling Green, with 0.08 inches recorded at the airport and 0.14 inches at the Mesonet station south of town. Today will feature another good shot at precipitation as a shortwave trough digs through the Ohio Valley, bringing a surface cold front through the area. However, moisture will be limited with this system as precipitable water values will only be around 1.2 inches, and no more than a quarter of an inch of rainfall is expected. This will not be the type of drought-busting rain that most of the state needs.
After the frontal passage, a deep upper-level trough and associated northwest flow aloft will move over the area. This will result in cooler conditions and more dry weather, with highs in the upper 60s and nighttime lows dipping into the lower 40s over the next few days. By Saturday, the axis of the trough will have moved to our east, resulting in beautiful weather for the weekend. On Saturday and Sunday, highs are expected to be in the mid 70s under sunny skies.
