AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
757 AM EDT WED JUL 18 2012

.UPDATE...
ISSUED AT 757 AM EDT WED JUL 18 2012

UPDATED THE FORECAST TO REFLECT THE CURRENT CONDITIONS AND MODEL
TRENDS. ONLY MADE SOME MINOR TWEAKS. IF THIS MORNING IS ANY
INDICATION OF WHAT WE CAN EXPECT THIS AFTERNOON...THEN WE CAN EXPECT
TO SEE QUITE A BIT OF RAIN FALLING FROM THESE SLOW MOVING STORMS. THE
REST OF THE FORECAST IS ON TRACK.

&&

.SHORT TERM...(TODAY THROUGH THURSDAY)
ISSUED AT 326 AM EDT WED JUL 18 2012

HIGH PRESSURE WILL REMAIN IN PLACE THROUGH THURSDAY...HOWEVER AN
UPPER LOW OVER EASTERN CANADA IS BEGINNING TO BUILD TO THE SOUTH.
THIS WILL PUSH A COLD FRONT TO THE SOUTH. BY THURSDAY AFTERNOON THE
FRONT WILL BE OVER NORTHERN KENTUCKY. AS A RESULT... WARM AND MOIST
AIR...THAT HAS ALSO BEEN RELATIVELY UNSTABLE...CONTINUES TO DOMINATE
THE WEATHER. THE FORECAST CHALLENGE HAS BEEN ON TRYING TO FIND SOME
TRIGGERS THAT WILL RESULT IN SHOWERS AND THUNDERSTORMS BUILDING OVER
THE AREA. THE MODELS HAVE BEEN NOT PROVIDED MUCH HELP IN TRYING TO
IDENTIFY THESE TRIGGERS. IN GENERAL...CONFIDENCE IN THE MODELS HAVE
BEEN WELL BELOW NORMAL. AN EXAMPLE WOULD BE THE TIME HEIGHT THAT IS
USED TO HELP WITH POINT FORECASTS. THE NAM TIME HEIGHT HAS A STRONG
AREA OF OMEGA MOVING ACROSS THE AREA FROM NOON TO 4 PM WHILE THE GFS
IS SHOWING ONE MOVING ACROSS THE AREA BETWEEN 4 AND 9 AM THIS
MORNING. DUE TO THE LACK OF CONFIDENCE IN MODEL TIMING...AM ONCE
AGAIN GOING TO STAY WITH A PERSISTENCE FORECAST AND WILL CONTINUE TO
KEY IN ON SUBTLE CHANGES TO TWEAK THINGS UP OR DOWN. THE CAPPING IN
THE MID LAYERS HAVE ABATED SOME TODAY AND SO EXPECT THE AFTERNOON
ACTIVITY TO BE A LITTLE MORE ROBUST TODAY. THE PRECIPITABLE WATER HAS
ALSO INCREASED TO ABOUT 1.8-2.0 INCHES. THIS MAKES THE THREAT OF SOME
LOCALIZED NUISANCE FLOODING MORE LIKELY TODAY AND ALSO DECREASED THE
SEVERE WIND THREAT. EVEN THOUGH SPC HAS PUT EASTERN KENTUCKY IN A 5
PERCENT CHANCE OF SEVERE WIND GUSTS...I ACTUALLY THINK THE THREAT FOR
SEVERE WINDS IS ACTUALLY LESS THAN YESTERDAY SINCE THERE IS NO DRY
AIR ALOFT. THE CAPE IS VERY HIGH TODAY...HOWEVER THE MOIST AIR SHOULD
HELP TO REDUCE THE WIND THREAT. WITH A 15K FOOT FREEZING LEVEL...IT
WILL BE PRETTY HARD TO GET ANY LARGE HAIL TODAY. THE MODELS ARE IN
PRETTY GOOD AGREEMENT FOR SOME HEAVY RAIN POTENTIAL ON THURSDAY. THE
PRECIPITABLE WATER IS AROUND 2 INCHES AND THE WIND FLOW IS PRETTY
WEAK. AT THIS POINT IN TIME...NOT EXPECTING ANYTHING
WIDESPREAD...JUST LOCALIZED OVER AREAS THAT GET STORMS THAT
REPEATEDLY MOVE OVER THE SAME AREA. FOR TEMPERATURES...THE MODELS
ARE ALL VERY CLOSE AND SO HAVE JUST NUDGED THE TEMPS TOWARD THE
CONSENSUS BLEND. CONTINUED WARM AND HUMID CONDITIONS WILL MAKE
OUTDOOR ACTIVITIES DIFFICULT AGAIN TODAY.

.LONG TERM...(THURSDAY NIGHT THROUGH TUESDAY)
ISSUED AT 326 AM EDT WED JUL 18 2012

THE MODELS WERE IN GOOD AGREEMENT FOR DAYS 3-5 OF THE FORECAST. THE
OVERALL PATTERN WILL FEATURE A COLD FRONT MOVING OUT OF THE GREAT
LAKES AND ACROSS THE OHIO AND TENNESSEE VALLEYS. THE FRONT WILL SLOW
A BIT AS IT TRAVERSES THE MOUNTAINOUS TERRAIN OF EASTERN KENTUCKY
AND WEST VIRGINIA ON FRIDAY. THE LATEST COMPUTER GUIDANCE AND MODEL
SOLUTIONS ARE SUPPORTIVE OF 60-70 PERCENT PRECIPITATION
PROBABILITIES. THEREFORE...THE GRIDS WERE UPDATED TO REFLECT THIS.
FROM SUNDAY ONWARD THE MODELS BECOME A BIT MORE UNCERTAIN...WITH THE
ECMWF BRINGING MULTIPLE ROUNDS OF ISOLATED TO SCATTERED SHOWERS AND
STORMS INTO EASTERN KENTUCKY...WHILE THE GFS KEEPS THE AREA DRY FROM
SUNDAY THROUGH TUESDAY. WITH THE ECMWF BEING THE MORE WELL
ESTABLISHED AND RELIABLE LONG TERM MODEL...DECIDED TO DEFER TO ITS
SOLUTION FOR NEXT WEEKS WEATHER. WENT WITH CHANCES OF RAIN SUNDAY
THROUGH TUESDAY...WITH THE BEST CHANCES OF SHOWERS AND STORMS DURING
THE AFTERNOON AND EVENING HOURS. THE CORRESPONDING QPF AND SKY COVER
FORECAST ELEMENTS WERE UPDATED TO REFLECT THE NEW PRECIPITATION
PROBABILITY FORECAST.

TEMPERATURES THROUGHOUT THE PERIOD WILL BE CLOSE TO NORMAL FOR THIS
TIME OF YEAR. WITH PERSISTENT CLOUD COVER AND PRECIPITATION
EXPECTED...KEPT DAYTIME HIGHS A FEW DEGREES BELOW THE LATEST
COMPUTER GUIDANCE NUMBERS. OVERNIGHT LOWS WILL BE IN THE UPPER 60S
AND LOWER 70S ACROSS THE BOARD. WINDS AND OTHER ELEMENTS OF THE
FORECAST WERE TWEAKED A BIT BASED ON THE LATEST DATA AND TO
ESTABLISH TRENDS.

&&

.AVIATION...(FOR THE 12Z TAFS THROUGH 12Z THURSDAY MORNING)
ISSUED AT 1157 AM EDT WED JUL 18 2012

ISOLATED THE SCATTERED STORMS ARE EXPECTED THIS MORNING ACROSS THE
AREA. THIS AFTERNOON STORMS SHOULD BECOME MORE WIDESPREAD. EXPECT
SOME TEMPO IFR UNDER THE STORMS HOWEVER TIMING IS STILL TOO UNCERTAIN
TO TRY AND PREDICT EXACTLY WHEN STORMS WILL FORM THIS AFTERNOON. THE
MOST LIKELY TIME WILL BE FROM 18-22Z. EXPECT SOME VALLEY FOG TO FORM
TONIGHT...HOWEVER A LOT WILL DEPEND ON HOW MUCH RAIN FALLS TODAY. IF
THERE IS A LOT OF RAIN...WILL MOST LIKELY SEE SOME VLIFR AT SME AND
LOZ.
