.DISCUSSION...
A slow moving cold front will bring a wind shift from
southwesterly today to northerly late tonight into Monday. While
there is a low (15-20%) chance for a pop up storm this afternoon
across the Bluegrass, the higher chances (30-40%) will be along
and north of roughly the I-64 corridor late this evening through
Monday morning. Given 10-20 kt southwest transport winds this
afternoon and deeper mixing, dispersion will be a bit better
compared to previous days. In addition, with afternoon dewpoints
falling into the low 60s, RH values will drop into the 30s.
