There is a FROST ADVISORY for the area tonight (Sunday night).  Under a clear sky, expect the temperature to drop into the mid 30s.  With a light breeze, scattered areas of frost could develop.  I don’t expect this to be a killing frost, but delicate plants could be ‘nipped’ a little by the frost.  If you choose to cover delicate or newly planted plants, cloth is the best covering.  You can use plastic, but be sure to put little stakes in the ground so the plastic doesn’t directly touch the plants.  You can also use paper if you like.  Most plants will make it through tonight, but it’s those delicate or newly planted plants that are most at risk.

The energy from a huge Solar flare may offer us a chance to see a rare view of the Northern Lights tonight.  You’ll have to get out to a very dark place, away from artificial lights.  The light show may be very subtle for us, but it’s certainly worth a try at viewing.  Good luck!  I didn’t make the graphic and want to credit AccuWeather (I believe).  The map is very good and has been posted on several sites.  There is no ideal time for viewing, but it has to be well after dark.

Scattered showers will linger through the early evening hours.  Colder tonight and cooler for the next couple of days.  Then, we’ll warm up a bit as another chance for rain moves in.

SEVERE THUNDERSTORM WATCH for all News 10 counties, except Knox, Greene, Daviess and Martin until 9pm, Indiana time.  Expect heavy rain, gusty wind and dangerous lightning in these storms.  Up to the minute information will be broadcast on WTHI-TV 10.

Colder than average weather continues today, but it will not be as windy.  Friday, a little warmer.  There will be a change for a wintry mix of precipitation beginning later Saturday.  Temperatures will remain below average for the next week.
