Minor Non Convective Wind Event and Possible First Frost

As the upper level low departs and as a drastic change in air mass occurs overnight, a slight gradient wind event is occurring.  The strongest pressure gradient is farther north; however, current sustained winds measured at Mesonet sites around Southern Kentucky and throughout Kentucky are reading pretty breezy at around 15 mph with the highest wind gusts approaching 30 mph.  The interesting part about the readings is the Warren County Mesonet Site seems to be getting the highest wind readings whereas surrounding Mesonet Sites are reading wind speeds lower.  Gusts have been strongest at the Warren County Mesonet Site as well.

As the weekend approaches, a drastic cool down will occur, with highs expected to be in the low 60s on Saturday.  Saturday Night, with mostly clear and nearly calm conditions expected, the first frost of the season is forecast.  This would be right on time for Bowling Green based on the average date for the first frost of the season, which is October 2.

After Saturday, a ridge will build into much of the CONUS, and more seasonable temperatures will be in place.
