Those warming temperatures will drop again to the low teens and torrential rain will hit certain areas - particularly in the south.
Today will be mostly cloudy early this morning but low clouds, mist, and fog will break up through the morning leaving another pleasant day of sunny spells.
A scattering of showers will also develop, mostly during the afternoon hours.
The highest temperatures of 13 to 18 degrees are expected in the midwest away from onshore breezes along southern and eastern coasts in light to moderate southeast breezes.
