Area forecast discussion, Jul 9, 2:51 PM EDT, 32 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
251 PM EDT THU JUL 9 2015

.SHORT TERM...(THIS EVENING THROUGH FRIDAY NIGHT)
ISSUED AT 250 PM EDT THU JUL 9 2015

SIGNIFICANT WIND DAMAGE OCCURRING WITH BOWING SEGMENTS OF STORM
COMPLEX CURRENTLY IN THE WEST CENTRAL PART OF THE FORECAST AREA.
SEVERE THREAT WILL CONTINUE THROUGH THE REMAINDER OF THE
AFTERNOON AS WEAK SURFACE COLD FRONT CONTINUES TO SAG SOUTHEAST
ACROSS KY. THE SEVERE THREAT WILL COME TO AN END WITH THE LOSS OF
DAYTIME HEATING...AND THE LATEST SHORT RANGE GUIDANCE...INCLUDING
THE HRRR SUPPORTS A QUIET NIGHT AHEAD. THE FRONT WILL STALL
ACROSS THE AREA LATER TONIGHT...AND YET ANOTHER SHORT WAVE TROUGH
WILL MOVE EAST FROM THE CENTRAL PLAINS LATE TONIGHT AND FRIDAY
MORNING. THIS WILL BRING ANOTHER GOOD CHANCE OF THUNDERSTORMS
FOR FRIDAY.

.LONG TERM...(SATURDAY THROUGH THURSDAY)
ISSUED AT 250 PM EDT THU JUL 9 2015

FLAT UPPER LEVEL RIDGING CURRENTLY ACROSS THE SOUTHEAST UNITED
STATES WILL BUILD WEST INTO THE SOUTHERN PLAINS THIS WEEKEND AND
THEN NORTH ACROSS THE PLAINS EARLY NEXT WEEK. WE WILL REMAIN ON
THE NORTHWEST PERIPHERY OF THE RIDGE AS WE MOVE INTO NEXT WEEK
WITH PERIODIC SHORT WAVES MOVING SOUTHEAST IN NORTHWEST FLOW.
WHILE THE SPECIFIC TIMING OF THESE WAVES IS UNCERTAIN AT THIS
TIME...THE BOTTOM LINE IS THAT THIS PATTERN WILL RESULT IN A
CONTINUED THREAT FOR THUNDERSTORMS EVERY DAY. WITH THE THREAT FOR
MCS DEVELOPMENT TO OUR NORTHWEST IN THIS TYPE OF PATTERN THE
STORMS WILL NOT NECESSARILY BE TIED TO THE DIURNAL HEATING CYCLE.
TEMPERATURES WILL REMAIN NEARLY UNCHANGED THROUGH THE PERIOD WITH
HIGHS MOSTLY IN THE MIDDLE AND UPPER 80S AND LOWS IN THE UPPER 60S
AND LOWER 70S.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z FRIDAY AFTERNOON)
ISSUED AT 149 PM EDT THU JUL 9 2015

A SLOW MOVING COLD FRONT CONTINUES TO SAG SOUTH ACROSS THE OH
VALLEY. SCATTERED STRONG TO SEVERE STORMS ARE OCCURRING AHEAD OF
THIS BOUNDARY ACROSS EASTERN KY. THE SEVERE STORMS MOVING OUT OF
SOUTH CENTRAL KY SHOULD REMAIN JUST NORTH OF SME AND LOZ...WHILE
STORMS AFFECTING SJS WILL BE ENDING SHORTLY. GREATEST THREAT FOR
THUNDERSTORMS WILL REMAIN ACROSS THE CENTRAL PART OF THE FORECAST
AREA THIS AFTERNOON. THE THUNDERSTORM THREAT WILL DIMINISH AFTER
SUNSET...BUT FOG AND LOW CLOUDS ARE EXPECTED TO DEVELOP TONIGHT
RESULTING IN IFR CONDITIONS ACROSS MOST OF THE AREA. CONDITIONS
WILL GRADUALLY IMPROVE ON FRIDAY...BUT MVFR CEILINGS ARE EXPECTED
TO PREVAIL DURING THE MORNING EVEN AFTER VISIBILITY IMPROVES TO 7
OR GREATER MILES. VFR CONDITIONS SHOULD RETURN DURING THE
AFTERNOON ON FRIDAY.
