AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
752 PM EST FRI MAR 31 2006

.DISCUSSION...

TRAILING EDGE OF SHRA NOW CROSSING MIDWAY THRU THE CWFA. DWPTS
REMAIN HIGH WITH THE INFLUX OF SRLY WINDS AND DWPTS TO OUR WEST ARE
EVEN HIGHER. HAVE RAISED MIN TEMPS TONIGHT TO REFLECT HIGHER DWPTS.
CLEARING DOES NOT GET HERE UNTIL NEAR DAWN SO MVFR TO IFR CIGS
POSSIBLE THIS MORNING. HAVE UPDATED FCST TO REFLECT HIGHER MIN TEMPS
AND LOWER POP WITH ENDING PCPN FROM WEST TO EAST...MAINLY BEFORE
MIDNIGHT. SOME LINGERING PCPN POSSIBLE IN OUR EXTREME ERN COUNTIES
UNTIL EARLY MORNING. QPF AT JKL OVER THE PAST 6 HR WAS .26 INCHES
AND DO NOT EXPECT MORE THAN A TENTH OF AN INCH MORE. FROM THE 88D
AND SOME SPOTTER REPORTS THIS SEEMS TYPICAL OF THE AREA. EXPECT
WINDS TO PICK UP FROM THE SOUTH AND BECOME GUSTY BUT THE FNT SHOULD
COME THRU MOSTLY DRY WITH JUST A WIND SHIFT TO MARK PASSAGE. SKY
TOMORROW WILL CLEAR AND WITH DRIER AIR MIXING IN...THE SUN WILL MAKE
SOME TEMP RECOVERY BUT NOT AS WARM AS FRI.

STRONG STORMS IN IN/OH THIS EVENING SHOULD REMAIN NORTH OF THE RIVER
AS THE MAIN LOW PULLS THE MAJORITY OF THE ENERGY INTO CANADA TONIGHT
AS IT CONTINUES TO TRACK NE. ANOTHE COUPLE OF STORMS IN CNTRL TN
CONTINUE TO MOVE ESE AND ALSO SHOULD NOT BECOME A PROBLEM FOR ERN
KY. WINDS AND CLOUD COVER WILL PREVENT FOG.

.PREV DISCUSSION...

500 PM EST FRI MAR 31 2006

DEEP LOW IS MOVING INTO THE GREAT LAKES. A COLD FRONT EXTENDS SOUTH
FROM THE LOW FROM WESTERN MI DOWN INTO SE MO. A NOTABLE DRY SLOT WAS
BEHIND THE PREFRONTAL BAND OF SHOWERS...ASSOCIATED WITH A TROUGH
AHEAD OF THE MAIN SYSTEM. NOT MUCH THUNDER IS ASSOCIATED WITH THIS
OVER KY...HOUGH SOME HAS BEEN NOTED OVER CENTRAL AND WESTERN KY
CLOSER TO THE FRONT AND THE EASTERN EXTENT OF THE DRY SLOT.

THE SEVERE THREAT OVER THE CWA APPEARS RATHER MINIMAL...MORE FOCUSED
TO THE WEST AND NW OF THE CWA...WHERE TIMING OF FROPA WILL BETTER
COINCIDE WITH SOME RECOVERY OF INSTABILITY BEHIND THE EARLIER RAIN
BAND. WIND FIELDS DO REMAIN RATHER STRONG...SO ANY STRONGER STORMS
THIS EVENING COULD MIX DOWN THIS HIGHER MOMENTUM AND PRODUCE STRONG
WIND GUSTS. WITH DRIER MID LEVEL AIR MOVING IN...WBZ HEIGHTS ARE
LOWERING SO SOME HAIL WITH THE STRONGEST STORMS CANNOT BE RULED OUT
ALTOGETHER. HOWEVER...THE MAIN THREAT IS NW OF THE REGION. THESE
ADDITIONAL SHOWERS AND SCATTERED THUNDERSTORMS ARE EXPECTED TO
ACCOMPANY THE COLD FRONT AS IT PUSHES EAST OVERNIGHT. CONTINUED WITH
HIGH POPS OVERNIGHT...CLOSE TO MOS VALUES. TEMPS WILL REMAIN MILD
OVERNIGHT AS THEY WILL BE HELD UP BY INCREASED MOISTURE AND CLOUD
COVER AND WINDS.

HIGH PRESSURE WILL BUILD INTO THE REGION ON SAT...WITH SLOW CLEARING
AS SOME MOISTURE WILL BE TRAPPED AROUND 8H. WITH RATHER EXTENSIVE CU
AND SC ANTICIPATED TOMORROW...TRENDED MAX TEMPS DOWN TOWARD THE
COOLER 12Z MOS NUMBERS. THE HIGH AT THE SFC ALONG WITH UPPER LEVEL
RIDGING WILL SETTLE ACROSS THE REGION ON SAT NIGHT...WITH DECENT
RADIATIONAL COOLING EXPECTED...ESPECIALLY OVER THE WESTERN PART OF
THE CWA. SOME LOWER CLOUDS COULD LINGER OVER THE EAST PER NAM INTO
SAT NIGHT. OPTED FOR A MODERATE RIDGE VALLEY SPLIT. SINCE AIR IS NOT
EXPECTED TO DRY OUT THAT FAST TOMORROW...SOME VALLEY AREAS SHOULD
FALL TO THE DEWPOINT FOR SOME VALLEY FOG LATE SAT NIGHT.

THE COLD FRONT IS STILL EXPECTED TO RETURN NORTH TOWARD THE REGION ON
SAT NIGHT AND CROSS THE AREA ON SUNDAY. SOME SHOWERS AND
THUNDERSTORMS MAY DEVELOP ON ISENTROPIC LIFT AHEAD OF THE
BOUNDARY...BUT THE COVERAGE OF THE GFS MAY BE OVERDONE. ADDITIONAL
SHOWERS AND THUNDERSTORMS ARE POSSIBLE IN THE WARM SECTOR ON SUN
NIGHT. THE CHANCE FOR SHOWERS AND MAYBE A THUNDERSTORM WILL LINGER
INTO MONDAY AM UNTIL THE COLD FRONT CROSSES THE AREA. A RIDGE OF
HIGH PRESSURE WILL BEGIN TO BUILD INTO THE REGION TO END THE PERIOD.

EXTENDED...(TUESDAY THROUGH FRIDAY) GFS AND ECMWF IN GOOD AGREEMENT
WITH NEXT WEEKS WEATHER SYSTEM...DECIDED TO GO WITH GFS FOR
CONTINUITY. GFS HAS A STRONG RIDGE OF HIGH PRESSURE MOVING INTO THE
CENTRAL UNITES STATES...BOTH AT THE SURFACE AND MIDDLE LEVELS OF THE
ATMOSPHERE...TUESDAY THROUGH THURSDAY OF NEXT WEEK. AN AREA OF LOW
PRESSURE IS FORECAST TO MOVE OUT OF THE PLAINS AND INTO THE EASTERN
HALF OF THE UNITED STATES LATE THURSDAY NIGHT INTO FRIDAY MORNING.
WITH SOUTHERLY FLOW LIKELY TO INCREASE AHEAD OF THE ASSOCIATED COLD
FRONT...TEMPERATURES SHOULD WARM TO ABOVE NORMAL VALUES...ALONG WITH
AN INCREASE IN SURFACE MOISTURE. MODEL SOUNDINGS NOT SHOWING A WHOLE
LOT OF NEAR SURFACE INSTABILITY AT THIS TIME. HOWEVER...THE JET
STREAM AND BOTH LOW AND MIDDLE LEVELS OF THE ATMOSPHERE...WILL BE
INTERACTING FAVORABLY DURING FRONTAL PASSAGE...WHICH COULD HELP
OVERCOME THE LACK OF SURFACE INSTABILITY. BEARING THIS IN MIND...WENT
WITH A CHANCE FOR THUNDERSTORMS LATE FRIDAY MORNING THROUGH FRIDAY
EVENING.

DEWPOINTS AND QPF WERE IN GOOD SHAPE AND ADJUSTED ONLY SLIGHTLY.
WINDS WERE A LITTLE OUT SORTS...SO LOADED IN DGEX MODEL WINDS AND
TWEAKED THEM TO BETTER REFLECT THE PASSAGE OF THE FRONT NEXT FRIDAY.
SKY COVER LOOKED GOOD AND WAS ADJUSTED ONLY SLIGHTLY AS WELL.
TEMPERATURES WERE IN PRETTY SHAPE...BUT WERE ADJUSTED SLIGHTLY
TOWARD MEXMOS. HIGH TEMPERATURES WERE GENERALLY ADJUSTED SLIGHTLY
ABOVE OR BELOW MEXMOS...ESPECIALLY FOR THURSDAY AND FRIDAY WHEN
CLOUDS...LOW LEVEL MOISTURE AND PRECIPITATION WILL BE INCREASING
RESPECTIVELY. REST OF EXTENDED FORECAST IN GOOD SHAPE.

1102 AM EST FRI MAR 31 2006

OVERALL...THE ONGOING FORECAST LOOKS TO BE IN GOOD SHAPE...WITH ONLY
A FEW CHANGES FOR THE LATEST TRENDS. HOURLY TEMPS WERE RUNNING ABOVE
THE CURRENT FORECAST SO MADE SOME MINOR CHANGES TO HOURLY T FOR THE
TODAY PERIOD. A DEEP OCCLUDED LOW IS TRACKING FROM MN INTO THE
WESTERN GREAT LAKES. A COLD FRONT EXTENDED SOUTH FROM THE LOWS DOWN
INTO EASTERN IL AND INTO SE MO AND DOWN INTO OK. WIND FIELDS WITH
THIS SYSTEM WILL BE RATHER STRONG (MID LEVEL FLOW OF 50+ KTS AND
LOCAL VWP HAS WINDS AT 6KFT OF 40+ KTS)...BUT INSTABILITY IS RATHER
LIMITED (500 J/KG OF CAPE AND LI OF -2 TO -3C AT BEST) AND DEBRIS
CLOUDS WILL SUPPRESS HEATING. THE GREATEST THREAT WOULD APPEAR TO BE
OVER THE WESTERN PART OF THE CWA...WHERE MOISTURE RECOVERY IS BEST
AND CONINCIDE WITH THE STRONGER WINDS ALOFT. THE HWO HAS A GOOD
HANDLE ON THIS...SO NO CHANGES WILL BE MADE AT THIS TIME.

542 AM EST FRI MAR 31 2006

LOW PRESSURE SYSTEM WAS LOCATED OVER SOUTHERN MINNESOTA THIS
MORNING. NATIONAL RADAR HAS SHOWN THE OVERNIGHT TRANSFORMATION OF
MULTIPLE LINES OF CONVECTION INTO A SINGLE BROAD BAND OF SHOWER AND
THUNDERSTORM ACTIVITY. EXPECT MUCH OF THIS ACTIVITY TO DISSIPATE AS
THE BAND ROTATES NORTHEASTWARD. BUT THAT DOES NOT RULE OUT THE
POSSIBILITY OF A FEW SHOWERS OR THUNDERSTORMS THIS MORNING.

THIS SYSTEM WILL RELOCATE TO THE GREAT LAKES REGION BY THIS EVENING.
IN THE PROCESS WARM...MOIST AIR WILL CONTINUE TO BE PUMPED INTO THE
AREA ON THE BACK OF BREEZY SOUTHWEST WINDS. WITH THE HELP OF DAYTIME
HEATING...SHOWERS AND THUNDERSTORMS WILL REDEVELOP AND MOVE EASTWARD
AS THE DAY PROGRESSES. SPC REMOVED EASTERN KENTUCKY FROM THE SLIGHT
RISK TODAY. HOWEVER...MUCH OF THE REST OF KENTUCKY REMAINS IN A
SLIGHT RISK.

MODELS WERE IN GOOD AGREEMENT THIS MORNING AND THE FORECAST PACKAGE
WAS ALSO IN GOOD SHAPE. FRONTAL BOUNDARY WILL PUSH THROUGH TO OUR
SOUTH AND STALL OUT BEFORE RETURNING SUNDAY AS A WARM FRONT. THIS
FEATURE WAS WHERE THE NAM AND GFS HAD THEIR BIGGEST DISPARITY. THE
GFS BRINGS MUCH MORE MOISTURE AND PRECIP BACK INTO THE AREA FOR
SUNDAY. TEND TO WANT TO LEAN TOWARDS THE GFS SOLUTION. HOWEVER...
WILL WAIT FOR ANOTHER RUN OR TWO BEFORE BITING. CONSEQUENTLY...
CONTINUED PREVIOUS SHIFTS SLIGHT POPS ON SUNDAY FOR NOW.

THERE WAS SOME INITIAL CONCERN OVER FIRE WEATHER...AS
DOWNSLOPE FLOW WAS KEEPING RELATIVE HUMIDITIES QUITE LOW OVERNIGHT.
HOWEVER...WINDS SHIFTED MORE OUT OF THE SOUTHWEST AND DEW POINT
RESPONDED IN KIND...RISING QUICKLY INTO THE LOW TO MID 40S BY
ISSUANCE TIME. OTHERWISE...THE MOST SIGNIFICANT CHANGES TO THE
FORECAST WAS TO TWEAK TEMPS BASED ON THE LATEST MOS GUIDANCE.

.JKL WATCHES/WARNINGS/ADVISORIES...NONE.
