Scattered thunderstorms will be possible this evening, east of

low however one can not be ruled out, mainly along and east of the
Highway 63 corridor. Frequent cloud to ground lightning will also
be possible with any thunderstorm.

push of cold air next week will increase frost and freeze
potential Monday night into Tuesday.

fire danger for much of the area Thursday.
