Rain has changed to snow with temperatures falling below freezing. The
heaviest precipitation currently is in a horseshoe from east of
Nashville into Warren county then southwest to clarksville with a
dry slot south of Nashville. This period of heaviest precipitation can
produce snowfall rates of 1/2 inch per hour overnight for several
hours. Snowfall will become lighter toward dawn and last through the
morning commute. totals of 3-5 inches with locally higher amounts are
possible overnight and Wednesday morning. The totals were raised based
on the current radar display showing heavy precipitation and our STN
WRF model which still produces plenty of precipitation for snowfall
overnight in this range. Temperatures will fall below freezing
leading to the development of slick spots. Roadways will become slick,
hazardous and perhaps snow covered for the commute to work or any
school buses.
