Rain moving in!

Current Conditions:
Currently there is an upper level low located well into Canada with a minor shortwave over southeast Tennessee.  At the mid-levels there is another shortwave over Kansas and Oklahoma which has helped for rain to develop over southeast Missouri and Illinois.  Associated with the shortwave at 700mb is moisture which is fueling the rain over the area.  Over Cheatham, the moisture has not moved into the area but should over night into early Friday.  Warm air has moved into the area this evening and we reached a high of 67 with mostly to partly cloudy skies.  Currently over Cheatham at the surface there is winds out of the south with a Low centered over Illinois and Indiana with a cold front stretching from Illinois down into Oklahoma with temperatures on the back side at 48 and below.  The current radar for Cheatham shows nothing, however expecting this to change overnight into the early morning with an approaching cold front. 
Radar imagery valid for 6:39 P.M. on February 7, 2013.
 
Forecast:     
The upper level trough to the north will move off to the east and by Friday afternoon we will have an upper level ridge over the area.  There will be upper level moisture associated with the cold front over Cheatham at 3:00 A.M. as the rain moves through.  As the cold front passes through the area, temperatures will begin to fall throughout the day.  The winds will be coming from the north at 17mph.  The rain will be moving through the area around 12:00 A.M. according to the latest HRRR output.


HRRR radar output valid for 12:00 A.M. on February 8, 2013.
The rain that will move through will not be severe.  The rain values associated with this system will be between 0.10" - 0.25".  I am not expecting much in rain across the area.  The rain will be out of Cheatham by 7:00 A.M.  The temperatures across Cheatham tonight at midnight will be 52 ahead of the cold front then as the rain moves in, the temperature will drop.  The high for Friday will be 52 and the temperature will drop throughout the day.  The low for tomorrow will be 38.  If you are not a member of the Cocorah's Network, they would love for you to join today and start reporting the rain that you receive at your house.  For more information go here.
