Excessive Rainfall Possible This Weekend; October Heat Wave in California

A slow moving front will be the focus area for heavy to excessive rainfall and a threat for flash/urban flooding across the northern Gulf Coast and Southeast U.S. through this weekend. Abnormally hot, potentially record-breaking, temperatures will impact southern California and stretch north toward the Bay Area and Central Valley into next week. Read More >

The month started off wet, with over an inch of rain soaking the region on the first day. Those rains made 2018 the wettest year on record at Lexington.

On December 8-9 the second ice storm of the season rolled across the region, coating outdoor objects in 0.10-0.28" of glaze in southern Kentucky.

Another round of heavy rain came through on the 14th-15th as low pressure moved very slowly from the lower Mississippi Valley into the Tennessee Valley. One to three inches of rain fell. It was these rains that made 2018 the wettest year on record at Frankfort.

The month ended with a bang as a squall line brought heavy rain and gusty winds to the region. A New Year's Eve EF-1 tornado briefly touched down between Corydon and Brandenburg. The heavy rains made 2018 Louisville's wettest year on record.
