A system in the Gulf could produce heavy rainfall and flash flooding for portions of the north-central Gulf Coast into Saturday. Widespread showers and thunderstorms are likely this afternoon into Friday from Central Plains into the mid-Mississippi Valley, Ohio Valley and Central Appalachians. Dangerous heat is expected from the Lower Mississippi Valley to the Mid-Atlantic today. Read More >

Overall, this October was a typically quiet fall month. As the temperatures started to cool, we had our first light frost on the morning of the 16th, followed by more frosts on the 17th and 31st. The Harrison County Kentucky Mesonet site fell to 26° on the 17th.

On the 28th-29th Hurricane Zeta cruised through the Gulf of America and into Louisiana while a strong upper low pushed eastward across the southern Plains. Widespread rain drenched the Ohio Valley, with 48-hour rainfall amounts in southern Indiana and north central Kentucky in the 2 to 4 inch range. Fortunately the ground was dry before the rains hit and there was very little flooding.

On the 23rd a cold front crossed the region and sparked scattered storms with gusty winds and some hail, mostly small. Hail between one and one and a half inches in diameter, however, did fall on southern Clark County, Indiana.
