Clinton Severe Watches & Warnings NOAA Weather Radio

... Subfreezing temperatures expected late tonight and early 
Friday... 

High pressure overspreading the area tonight will allow for
another night with unseasonably chilly temperatures across 
northern portions of central Indiana tonight and early Friday 
morning. Low temperatures are expected to fall into the upper 20s 
and lower 30s tonight. As winds relax overnight... frost accrual 
is anticipated... especially in sheltered areas.

While the growing season has not begun in earnest just yet over 
the northern portions of central Indiana... some planting of 
gardens and budding of fruit trees has taken place due to the 
recent warm spell. Take precautions to protect any sensitive 
vegetation overnight and early Friday.
