AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
624 AM CDT SAT JUL 14 2012

.UPDATE...
ISSUED AT 348 AM CDT SAT JUL 14 2012

UPDATED THROUGH SUNRISE BASICALLY TO COVER SCT SHOWERS
OCCURRING OVER SE MO AND ALONG THE OH/WABASH RIVER VALLEYS.

ALSO...UPDATED AVIATION SECTION. PLEASE SEE BELOW.

&&

.SHORT TERM...(TODAY THROUGH MONDAY NIGHT)
ISSUED AT 348 AM CDT SAT JUL 14 2012

MAIN FORECAST CONCERNS ARE TWO FOLD. FIRST WITH PRECIP/QPF THIS
WEEKEND...THEN WITH A BUILD UP OF HOT AND HUMID CONDITIONS AS WE
ENTER NEXT WEEK.

COL...OR MID LVL PRESSURE WEAKNESS BETWEEN HIGH PRESSURE SYSTEMS
TO OUR SOUTHEAST AND NORTHWEST WILL DOMINATE THE WEATHER THIS
WEEKEND. TROF AXIS TO REMAIN JUST N/W OF OUR FORECAST AREA...WHICH
WILL KEEP US WITH A WARM/MOIST AND UNSTABLE FEED OF AIR AT MANY
LEVELS OF THE ATMOSPHERE. SCT TO NUMEROUS SHOWERS WITH SCT
THUNDERSTORMS WILL MAINLY BE DAYTIME DRIVEN...WITH ONLY WEAK STUFF
LINGERING IN THE OVERNIGHT HOURS. STILL LOOKS AS THOUGH THE AXIS
OF MOST PRECIP WILL BE OVER WESTERN KY AND ALSO FROM FAR SE MO UP
THE OH RIVER VALLEY. DO NOT EXPECT THIS SYSTEM TO MAKE MUCH OF A
DENT IN THE OVERALL DROUGHT...BUT MANY LOCATIONS IN OUR AREA WILL
AT LEAST GET SHOWERS FROM TIME TO TIME THIS WEEKEND. GOOD NEWS IS
THAT WITH ALL THE MOISTURE IN THE AIR...AND WEAK WINDS
ALOFT...SEVERE STORM RISK WILL BE MINIMAL. THESE CONDITIONS MAY
ALSO LEAD TO SOME LOCALLY HEAVY RAINFALL IN SCT LOCATIONS...BUT
AGAIN...NOT EVERYWHERE...AND OFF AND ON IN NATURE.

SE U.S. MID LVL HIGH STILL LOOKS ON TRACK TO BULGE BACK TO THE NW
AS WE HEAD INTO EARLY NEXT WEEK. NOT GOOD NEWS FOR DROUGHT
STRICKEN AREAS LIKE US. IN FACT...PRECIP CHANCES WILL WANE
SIGNIFICANTLY EARLY NEXT WEEK AND MAX TEMPS WILL LIKELY SHOOT
BACK INTO THE MID 90S...WITH UNCOMFORTABLE HUMIDITY THIS TIME
AROUND. AFTERNOON HEAT INDEX VALUES IN THE 100 TO 105 RANGE
WOULD NOT BE SURPRISING MON.

.LONG TERM...(TUESDAY THROUGH FRIDAY)
ISSUED AT 348 AM CDT SAT JUL 14 2012

WITH RESPECT TO POPS/WEATHER...THE EXTENDED PERIOD STILL REMAINS
MURKY /A.K.A...LOW CONFIDENCE/ AS TO THE TIMING AND COVERAGE OF
CONVECTION AS THE MEAN RIDGE AXIS BUILDS IN JUST TO THE WEST OF THE
WFO PAH FORECAST AREA. GIVEN THE SURFACE FLOW FROM THE SOUTH AND
SOUTHWEST  AND THE PROXIMITY TO THE NORTHWEST FLOW ALONG THE BASE OF
THE WESTERLIES MOVING DOWN FROM THE UPPER MIDWEST/MISSISSIPPI VALLEY
REGION...THERE MAY BE AN INTERMIX BETWEEN DIURNAL AND SUB-SYNOPTIC
TO MESOSCALE FORCING ALONG THE EASTERN LIMB OF THE RIDGE CENTER.
ANY VARIATION IN THE TIMING OF MINOR SHORTWAVES MOVING SOUTHEAST
THROUGH THE AREA...MAY TURN THE RAIN FORECAST ON ITS HEAD...OR AT
LEAST OUT OF PHASE AS MUCH AS 180 DEGREES.

IN THE ABSENCE OF ANY MEANINGFUL CONVECTION AND CLOUD COVER...INSOLATION
AND GRADUAL INCREASE IN THICKNESSES SHOULD YIELD TEMPERATURES BACK
INTO THE LOWER AND MIDDLE 90S NEXT WEEK. UNFORTUNATELY...THE ONLY
THING THAT WILL KEEP TEMPERATURES FROM MOVING BACK TO THE 100 DEGREE
MARK WILL BE THE PERSISTENT SOUTHERLY FETCH OF UPPER 60/LOWER 70
DEW POINTS AND A SLIGHTLY MORE MORE MOIST BOUNDARY LAYER UNDER THE
SUBSIDENCE FROM THE RIDGE.

HEAT INDEX VALUES WILL LIKELY BE A GREATER CONCERN THROUGH THE
PERIOD. THE MOST CONSISTENT AREA OF SEEING AFTERNOON HEAT INDEX
VALUES IN THE 100 TO 105 DEGREE RANGE WILL BE SOUTHEAST MISSOURI
/WEST OF THE MISSISSIPPI RIVER/. SOUTHERN ILLINOIS...SOUTHWEST
INDIANA AND NORTHWEST KENTUCKY MAY 100+ HEAT INDEX VALUES TUESDAY
THROUGH THURSDAY...WITH SOME MODERATION LATE NEXT WEEK.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z SUNDAY MORNING)
ISSUED AT 617 AM CDT SAT JUL 14 2012

WITH THE 12Z ISSUANCE...ADDED INTERMITTENT MVFR CLOUD BASES AND
CEILINGS DURING ANTICIPATED PERIODS OF SHOWER ACTIVITY OVER TAF
SITES. MIDDLE LEVEL CLOUDS...GENERALLY BETWEEN 10KFT AND
20KFT..WERE ALSO ADDED AS THE DOMINANT CEILINGS FOR THE ENTIRE
FORECAST PERIOD. WITH THE EXCEPTION OF KCGI AFTER 08Z
SUNDAY...KEPT THE REMAINING TAF SITES WITHIN VFR VISIBILITIES
DURING THE LAST SIX HOURS OF THE FORECAST PERIOD.

DEPENDING ON THE EFFICIENCY/INTENSITY OF RAIN...THERE MAY BE BRIEF
VISIBILITY INTRUSIONS INTO THE MVFR LEVELS TODAY OR TONIGHT.

SCATTERED THUNDERSTORMS ARE EXPECTED TO INCREASE FROM SOUTHEAST
TO NORTHWEST OVER MUCH OF THE QUAD STATE REGION TODAY. SEVERE
STORMS ARE NOT ANTICIPATED. HOWEVER...DEADLY LIGHTNING AND LOCALLY
HEAVY RAINFALL IN SLOW MOVING STORMS WILL BE THE MAIN CONCERNS.

WILL REMAIN LOW. THE PRIMARY HAZARDS FOR ANY THUNDERSTORMS WILL BE
LOCALLY HEAVY RAINFALL AND DEADLY LIGHTNING. VERY ISOLATED

STRONGEST STORMS.
