Heat Coming to an End

Dewpoints at 4PM tomorrow are forecast to be steamy once again

Any sign of drought has been all but eradicated in south-central Kentucky. You'd have to go to the Jackson Purchase to find a portion of the state in a moderate drought. After a record-breaking month of rain in August for Bowling Green, we continue to see occasional showers and thunderstorms. On Tuesday, a line of thundershowers blossomed right over the city and further developed to the east. A minor frontal boundary was responsible for this precipitation, but it was rather shallow and was not carrying any Canadian air behind it. Long-range guidance is hinting at some fall-like air for next week, but I'll leave that as a teaser. Our first true autumn cold shot may be coming in the form of a strong cold front.

Though the "heat wave" has passed, the heat and humidity are still above early September averages. Dewpoints have consistently been between 70-75° during afternoon hours, which is downright sticky. It has been difficult to shake the heat thanks to high pressure placed over the mid-Atlantic coast. Tomorrow will be much like today; patchy fog in the early morning hours with highs near 90°. Mid-levels of the atmosphere will be slightly more unstable, so while the fluffy cumulus clouds will return, a stray shower or thundershower is also possible.

The greatest rain chances begin late Friday night as a cold front approaches from the northwest. Storms will be in a weakening mode upon arrival, but Saturday morning may be a wet one. The front may actually present itself in a couple rounds of precipitation, and will usher in cooler air for the weekend. Rain will dwindle by Saturday night, leaving Sunday to top out near . . . 80°? It's possible. Stay tuned to the WKU Storm Team as conditions change.

Tonight: Patchy fog around sunrise with a light south wind. Partly cloudy with a low of 71°.

Friday: Sun and clouds with a high near 89°. An isolated shower or thundershower is possible.Winds from the south at 5 mph.

Friday night: Mostly cloudy with winds becoming calm. Showers moving in late. Low around 71°

Have a good evening!
