Area forecast discussion, Mar 3, 10:26 AM EST, 11 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
1025 AM EST MON MAR 3 1997

WARM SECTOR NOSING INTO PARTS OF FAR SOUTHEAST KY WHERE MIDDLESBORO
HAS BROKEN OUT AND SHOT INTO THE LOW 60S AT 10 AM. KEEPING A CLOSE EYE
ON THE STORMS NORTH OF SOMERSET FOR SIGNS OF DEVELOPMENT. RADAR IS
INTERMITTENTLY INDICATING HAIL WITH THESE STORMS...BUT REFLECTIVITY
PATTERNS SHOWING NO ORGANIZATION AT THIS TIME.

OTHERWISE OUR FOCUS REMAINS ON THE FLOOD THREAT. SMALL STREAM/FLASH
FLOOD WARNINGS IN EFFECT FOR MOST OF OUR COUNTIES. WHILE RAINS HAVE
DIMINISHED FOR THE MOST PART...STILL PLENTY OF RUNOFF WITH NUMEROUS
ROADS CLOSED AND RISING CREEKS/STREAMS/RIVERS.

SINCE THE STEADIER RAINS HAVE MOVED NORTHEAST RECOMMEND THAT WE ALTER
THE WORDING A LITTLE TO REFLECT MORE SCATTERED SHOWERS/THUNDERSTORMS
EARLY THIS AFTERNOON DIMINISHING OR ENDING. HOWEVER WOULD LIKE TO
CONTINUE WITH FLASH FLOOD WATCH UNTIL THUNDERSTORM THREAT IS OVER AS
LOW MOVES NORTHEAST.

TEMPERATURES WILL PROBABLY BE HARD PRESSED TO REACH FORECASTED HIGHS
AS FLOW BECOMES NORTHERLY WITH GOOD COLD AIR ADVECTION BEHIND THE LOW.
WOULD PREFER UPPER 30S FOR NORTHERN COUNTIES...RANGING TO UPPER 60S AT
MIDDLESBORO WHICH WILL  SEE FALLING TEMPS THIS AFTERNOON.
