AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
632 PM CDT THU JUN 18 2009
.UPDATE...
UPDATED FOR LATEST TAF ISSUANCE. SEE AVIATION SECTION BELOW.
&&
.DISCUSSION... /ISSUED 329 PM CDT THU JUN 18 2009/
MAIN CHANGES WITH THIS PACKAGE WILL BE THE ISSUANCE OF A HEAT
ADVISORY FOR FRIDAY AFTERNOON AND ADJUSTMENT ON THE TIMING AND
FOCUS FOR THUNDERSTORMS TONIGHT THROUGH EARLY SATURDAY.
THE THERMAL CAP...COURTESY OF THE INCREASING SUBSIDENCE WITH THE
UPPER RIDGE PUSHING UP FROM THE LOWER MISSISSIPPI VALLEY...SHOULD
MAINTAIN HOLD ACROSS MOST OF THE WFO PAH FORECAST AREA TONIGHT. AT
THIS POINT IN TIME...BELIEVE ANY MEASURABLE THUNDERSTORM ACTIVITY
SHOULD REMAIN OUTSIDE OF THE FORECAST AREA TONIGHT. I CANNOT RULE
OUT AN ISOLATED THUNDERSTORM ALONG THE EDGE OF THE RIDGE CAP ALONG
AND NORTH OF THE INTERSTATE 64 CORRIDOR FROM OUTFLOWS ASSOCIATED
WITH MCS DEVELOPMENT AND TRANSLATION FURTHER NORTH...BUT HAVE LEFT
OUT OF THE CURRENT GRIDDED/TEXT/TABULAR FORECAST TONIGHT AND INTO
EARLY FRIDAY.
THE ECMWF...FOLLOWED BY THE GFS...AND TO SOME EXTENT THE SREF
NUMERICAL GUIDANCE ARE STALLING OUT THE COLD FRONT...AS IT RUNS
INTO THE RIDGE BUILDING IN FROM THE SOUTH ON FRIDAY. WITH THIS
PACKAGE...I CONTINUED AND REFINED THE SLOWER SOUTHEAST MOVEMENT OF
SHOWERS AND THUNDERSTORMS INTO THE WFO PAH FORECAST AREA FRIDAY
AFTERNOON AND INTO THE EARLY EVENING HOURS. THE LATEST DAY TWO
SEVERE WEATHER OUTLOOK HAS BEEN SHIFTING THE MODERATE RISK JUST
NORTH OF THE WFO PAH FORECAST AREA...WITH A SLIGHT RISK PERSIST
ACROSS THE NORTHERN HALF OF THE REGION.
ALTHOUGH MESOSCALE CONVECTIVE SYSTEMS /MCS/ WILL BE THE DOMINANT
THUNDERSTORM SCALE ACTIVITY THAT WILL IMPINGE ON OUR AREA...THE
COVERAGE AND INTENSITY WILL BE TEMPERED BY THE BUILDING RIDGE FROM
THE SOUTH. THERE STILL REMAINS THE POTENTIAL FOR BOW ECHO
DEVELOPMENT...SIMILAR TO WHAT WAS EXPERIENCED THIS MORNING OVER
SOUTHWEST INDIANA...BUT COVERAGE MAY BE LIMITED. I WILL ATTEMPT TO
ADDRESS CONVECTIVE MODE POTENTIAL IN MORE DETAIL IN THE HAZARDOUS
WEATHER OUTLOOK.
WITH RESPECT TO THE HEAT ADVISORY...LOCAL POOLING OF DEWPOINTS
UNDER THE RIDGE...AS WELL AS ABUNDANT INSOLATION...HAS ALREADY
PLACED A FEW LOCATIONS AT CRITERIA LEVELS FOR AN HOUR OR SO
YESTERDAY AND TODAY. HOWEVER...IT LOOKS LIKE A MORE PROLONGED
PERIOD OF HEAT AT OR CLOSE TO 105 DEGREES WILL BE LIKELY FOR MOST
OF THE WFO PAH FORECAST AREA ON FRIDAY. FOR NOW...PLAN TO ISSUE A
HEAT ADVISORY FOR NEARLY ALL OF THE WFO PAH FORECAST AREA FROM
NOON TO 7 PM FRIDAY.
AFTER SATURDAY AFTERNOON...RAIN CHANCES BECOME ESSENTIALLY
NIL...AS THE UPPER LEVEL RIDGE MOVES NORTHEAST INTO THE WFO PAH
FORECAST AREA. SO...HOPEFULLY...AFTER THIS EXTENDED PERIOD OF
UNSETTLED WEATHER...WE SHOULD HAVE DRY AND WARM CONDITIONS PERSIST
FROM SUNDAY THROUGH MOST OF NEXT WEEK.
