AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
732 PM EDT MON MAY 23 2011

.SHORT TERM.../TONIGHT THROUGH TUESDAY NIGHT/

18Z SFC ANALYSIS SHOWS DEEP LOW PRESSURE OVER NORTHERN LAKE MICHIGAN
WITH A COLD FRONT FROM THIS STRETCHED OUT TO THE WEST OF KENTUCKY.
THIS LOW CONTINUES TO SUPPORT A SOUTHWEST FLOW OF AIR INTO THE
REGION MOISTENING AND WARMING THE BOUNDARY LAYER THROUGHOUT THE OHIO
VALLEY. THE DAYTIME HEATING ACROSS EAST KENTUCKY GOT OFF TO A SLOW
START DUE TO THE RESIDUAL SHOWERS AND CLOUDS THROUGHOUT THE AREA FROM
THE DYING MCS THAT MOVED THROUGH AROUND SUNRISE. THESE CLOUDS HAVE
NOW MOSTLY CLEARED OFF AND THE INSTABILITY IS BUILDING...THOUGH IT
REMAINS AT A RELATIVE MIN THROUGH EAST KENTUCKY. PROBABLY OF GREATER
PORTEND ARE THE STORMS CURRENTLY DEVELOPING OVER SOUTHERN ILLINOIS
AND NORTH CENTRAL INDIANA. BECAUSE OF THE LAG IN THE DIURNAL HEATING
TODAY...TEMPERATURES ARE STILL IN THE MIDDLE AND UPPER 70S FOR MUCH
OF THE CWA...THOUGH LOW 80S ARE NOTED IN PLACES THAT HAVE MANAGED TO
SEE MORE SUNSHINE. MEANWHILE...DEW POINTS ARE HOLDING IN THE LOW TO
MID 60S.

THE MODELS ARE IN GOOD AGREEMENT ALOFT FOR THE SHORT TERM AS THEY
LIFT A COMPACT TROUGH INTO THE EASTERN GREAT LAKES...NORTH OF THE
RELATIVELY FAST SOUTHWEST FLOW ALONG THE OHIO RIVER. THIS SOUTHWEST
FLOW WILL CARRY WITH IT A DECENT SHORT WAVE LATER TONIGHT...THAT
WILL PUSH ACROSS NORTHERN KENTUCKY BY DAWN TUESDAY. THIS WAVE WILL
ALSO SERVE TO MAINTAIN THE RATHER FLAT FLOW THROUGH THE OHIO VALLEY
DURING THE DAY TUESDAY WHILE A CLOSED LOW CHURNS OVER THE SOUTHERN
HIGH PLAINS. THIS LOW WILL MOVE EAST DURING THE NIGHT WITH DOWNSTREAM
WEAK RIDGING PASSING OVER EAST KENTUCKY. WITH THE CLOSE AGREEMENT
AMONGST THE MODELS...GEM EXCLUDED...HAVE FOLLOWED A BLENDED SOLUTION
USING THE NAM12 AND 00Z ECMWF FOR WEATHER DETAILS. ALSO LEANED TOWARD
THE LATEST HRRR FOR THE NEAR TERM FORECASTING OF CONVECTION AND
TIMING THIS EVENING.

SENSIBLE WEATHER WILL BE ALL ABOUT THUNDERSTORM INITIATION THIS
EVENING AS WELL AS THE EXPECTATION OF A MORE ORGANIZED CONVECTIVE
SYSTEM MOVING IN FROM THE WEST LATER IN THE EVENING. THE GRIDS WERE
DRAWN WITH THIS LATTER ACTIVITY IN MIND AND SEVERAL ROUNDS POSSIBLE
THROUGH THE NIGHT. WHEN THE CONVECTION IS NOT AROUND PATCHY FOG CAN
BE EXPECTED...MAINLY IN THE VALLEYS. THE WRF SUGGESTS THAT A LARGE
CLUSTER OF STORMS WILL BE ONGOING TUESDAY MORNING AND ONLY SLOWLY
EDGE OUT TO THE NORTHWEST WITH TIME. GIVEN THE UPPER AIR PATTERN AND
SOME OTHER MODEL SUPPORT HAVE FOLLOWED A SIMILAR SCENARIO IN THE
GRIDS. THIS WOULD ENTAIL A NON-TYPICAL DIURNAL CYCLE TO THE
CONVECTION AS THE POPS WILL BE FALLING FROM WEST TO EAST WITH TIME
DURING TUESDAY AFTERNOON. THIS IS PLAUSIBLE AS WELL DUE TO THE RISING
HEIGHTS AND INBOUND RIDGING COMING IN AT THE MID LEVELS. EXPECT THE
EBB AND FLOW OF CONVECTIVE DEVELOPMENT...SLIGHT RIDGING ALOFT...AND
LOSS OF INSTABILITY WITH NIGHTFALL TO RESULT IN LOWER POPS TUESDAY
NIGHT INTO WEDNESDAY MORNING. AGAIN PATCHY FOG CAN BE EXPECTED
OVERNIGHT...PARTICULARLY IN THE VALLEYS.

FOLLOWED A BLEND OF THE ADJMET AND INHERITED GRIDS FOR TEMPS THROUGH
THE PERIOD. AS FOR POPS...ENDED UP CLOSEST TO THE MET NUMBERS...BUT
JUST ON THE LOW SIDE THROUGH WEDNESDAY.

.LONG TERM.../WEDNESDAY THROUGH MONDAY/

MODELS ARE IN GOOD AGREEMENT ALOFT FOR THE FIRST HALF OF THE
EXTENDED PORTION OF THE FORECAST. A PROGRESSIVE CLOSED LOW WILL
ROTATE ITS WAY EAST THROUGH THE PLAINS AND INTO THE MID MISSISSIPPI
VALLEY BY WEDNESDAY. AS THIS HAPPENS RIDGING WILL BUILD BRIEFLY OVER
THE SOUTHEAST PORTION OF THE NATION. HOWEVER...THIS LOW WILL OPEN UP
INTO A WAVE LATE THURSDAY INTO FRIDAY AND THEREAFTER DIFFERENCES
BEGIN TO MAGNIFY IN THE MODEL SOLUTIONS. WITH THE EXCEPTION OF
RE-ENFORCING ENERGY DROPPING OUT OF THE NORTHERN GREAT BASIN OF THE
ROCKIES AND INTO THE UPPER MIDWEST BY LATE IN THE WEEK...DYS5-6
GENERAL TIMING OF FEATURES IS VERY SIMILAR. HOWEVER...THE GFS WITH
SOME SUPPORT FROM THE GFS ENSEMBLE MEAN PUSHES THIS SECOND WAVE INTO
THE OHIO VALLEY REGION BY THE WEEKEND...DYS6-7. THE ECMWF AND GEM ARE
SLOWER AND MUCH FURTHER NORTH WITH THIS SECOND WAVE. THESE TIMING
DIFFERENCES CONTINUE TO LOWER CONFIDENCE FOR THE LATTER PART OF THE
EXTENDED. THE QUESTION REMAINS FOR THE HOLIDAY WEEKEND JUST HOW THE
EASTERN TROUGH EVOLVES IN THE WAKE OF THE AFOREMENTIONED SECONDARY
WAVE. OVERALL RUN TO RUN TRENDS HOWEVER...ARE FOR A SLOWER AND MORE
NORTHERLY TRACK WITH RESPECT TO THE SECOND SYSTEM MOVING OUT OF THE
ROCKIES LATE IN THE PERIOD.

MADE ONLY MINOR TWEAKS TO DYS3-5 WITH SUCH GOOD AGREEMENT IN
SOLUTIONS. FOLLOWED A BLEND OF THE INHERITED GRIDS...HPC GUIDANCE
AND LATEST MODEL GUIDANCE FOR FORECAST HIGHS AND LOWS THROUGH THE
FIRST PART OF THE LONG TERM...ALONG WITH MINOR TERRAIN DRIVEN
ADJUSTMENTS MADE FOR MINIMUMS. WHILE CONFIDENCE IS LOW FOR THE
LATTER HALF OF THE PERIOD...COULD NOT IGNORE OVERALL SLOWER AND MORE
NORTHERLY TREND TO SECOND SYSTEM. CONSEQUENTLY THIS IS WHERE MOST
SIGNIFICANT CHANGES WERE MADE TO THE FORECAST...BASICALLY TO TREND
HIGHER ON TEMPS AND LOWER ON POPS. FOR THE POPS...ENDED UP ON THE
DRYER SIDE OF MEX AND HPC GUIDANCE THROUGH THE HOLIDAY WEEKEND.

&&

.AVIATION.../00Z TO 24Z/...UPDATED

IT IS A LOW CONFIDENCE FORECAST THIS TIME AROUND...WITH
THUNDERSTORMS AND THEIR UNCERTAINTY BEING THE CONCERN. THUNDERSTORMS
IN NORTH CENTRAL KY SHORTLY BEFORE TAF ISSUANCE POSE THE BIGGEST
THREAT FOR THE NORTHERN PORTION OF THE FORECAST AREA FROM AROUND KJKL
NORTH THIS EVENING BETWEEN ABOUT 00Z AND 04Z...WITH STRONG WINDS
POSSIBLE. ONCE THESE PASS...IT IS NOT CLEAR HOW WELL THE OTHER STORMS
PRESENT OVER WEST KY AND WEST TN EARLY IN THE EVENING WILL HOLD
TOGETHER AS THEY MOVE EAST. EXTRAPOLATION OF THE ACTUAL ACTIVITY IN
WEST KY AND WEST TN PUTS IT IN OUR SW COUNTIES AROUND 03Z. THE NAM
AND HRRR SUGGEST ACTIVITY TO OCCUR OVERNIGHT AND TUE MORNING IN THAT
AREA...WHILE THE GFS IS MUCH FURTHER NORTH TOWARD THE OH RIVER. AT
THIS POINT WILL JUST INCLUDE VCTS IN TAFS AT KSME AND KLOZ FROM
03-06Z AND AGAIN FROM 11Z ON. FURTHER NORTH...INCLUDING KJKL...HAVE
USED A BREAK IN THE PRECIP THREAT OVERNIGHT AND ON TUE MORNING...WITH
VCTS USED AGAIN ON TUE AFTERNOON.
