.PREV DISCUSSION...
/ISSUED 642 PM CDT MON OCT 20 2014/

AN UPPER-LEVEL TROUGH AXIS IS PASSING THROUGH THIS AFTERNOON. THIS
SYSTEM HAS BEEN STARVED FOR MOISTURE WITH SHOWERS EVAPORATING AS
THEY MOVE INTO MUCH DRIER AIR ACROSS THE TENNESSEE VALLEY. SKIES
SHOULD REMAIN MOSTLY CLEAR TONIGHT WITH LIGHT NORTHERLY WINDS AS
SURFACE HIGH PRESSURE STARTS TO MOVE SOUTHWARD. TEMPERATURES WILL
FALL QUICKLY THIS EVENING AND END UP IN THE UPPER 40S TO AROUND 50
BY DAYBREAK ON TUESDAY.

THE UPPER TROUGH IS EXPECTED TO AMPLIFY ACROSS THE MID-ATLANTIC
REGION AND EVENTUALLY BECOME CLOSED BY WEDNESDAY. THIS WILL KEEP
OUR AREA UNDER THE INFLUENCE OF NORTHERLY FLOW AND SURFACE HIGH
PRESSURE FOR SEVERAL DAYS WITH COOL NIGHTS AND MILD AFTERNOONS. AN
UPPER-LEVEL RIDGE SHOULD AMPLIFY ACROSS THE WESTERN U.S. BY THE
END OF THE WEEK WHICH COULD CAUSE A SHORTWAVE TO DIG SOUTHWARD
ACROSS OUR AREA...BUT FOR NOW MOISTURE RETURN IS EXPECTED TO BE
INSUFFICIENT FOR RAINFALL.
