AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
336 AM EDT FRI APR 18 2014

.SHORT TERM...(TODAY THROUGH SATURDAY)
ISSUED AT 336 AM EDT FRI APR 18 2014

DURING THE NIGHT...A MID/UPPER LEVEL TROUGH AND A DYING SURFACE COLD
FRONT WAS WERE APPROACHING THE REGION FROM THE WEST AND NORTHWEST
RESPECTIVELY. THE MOST SIGNIFICANT PORTION OF THE TROUGH WAS HEADING
TOWARD THE GULF COAST REGION AND WAS TRIGGERING SURFACE LOW
DEVELOPMENT THERE. AN EXTENSIVE CIRRUS SHIELD EXTENDED NORTH TO THE
OHIO VALLEY.

THE COLD FRONT SHOULD DEGRADE TO AN INVERTED TROUGH ASSOCIATED WITH
THE SOUTHERN LOW AND WILL NOT BRING ANY SIGNIFICANT CHANGE IN AIR
MASS. THE SOUTHERN LOW WILL PROGRESS SLOWLY TO THE ENE THROUGH
SATURDAY. WE WILL REMAIN AT THE NW PERIPHERY OF ITS INFLUENCE. OUR
LOW LEVEL AIR MASS IS NOT EXPECTED TO MOISTEN ENOUGH TO ALLOW FOR
PRECIP. HOWEVER...EXTENSIVE CLOUDS WILL BE PRESENT THIS MORNING. THE
CLOUD SHIELD IS EXPECTED TO SHOW AN OVERALL SHIFT TO THE SE WITH
TIME...EVENTUALLY ALLOWING FOR SUNNY TO PARTLY SUNNY SKIES OVER THE
LOCAL AREA ON SATURDAY.

WITH THE CLOUDS BEING MOSTLY CIRRUS TODAY...WILL LOOK FOR ENOUGH
INSOLATION FOR MILD AFTERNOON TEMPS AROUND 70. HOWEVER...THIS WILL BE
DEPENDENT ON THE THICKNESS OF THE CLOUDS. IF THE CLOUDS ARE DENSE
ENOUGH...IT COULD HOLD TEMPS DOWN...WHICH LOWERS CONFIDENCE IN THE
TEMPERATURE FORECAST FOR TODAY.
