Area forecast discussion, Oct 5, 2:13 PM CDT, 6 hours 18 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
213 PM CDT THU OCT 5 2000

THE TIMING OF 1000-700 MB FRONTAL SLOPE AND ATTENDENT FRONTEGENETIC
FORCING WILL BE THE KEY TO PCPN ACROSS THE WFO PAH FORECAST AREA
TONIGHT...AND POSSIBLY INTO FRIDAY.

AT 18Z...LAPS DATA...COMBINED WITH IR SATL AND REGIONAL RADAR MOSAIC
SHOWING MAIN PCPN BAND WELL BEHIND SHALLOW COLD FRONTAL BOUNDARY
ROUGHLY LOCATED FROM JUST SOUTHEAST OF KFAM TO KSLO. PCPN ALONG THE
SFC-925 MB FRONTAL BOUNDARY...LOCATED ALONG THE NRN LIMB OF THE
FORECAST AREA BTWN 12Z-15Z THIS MORNING...WAS ENHANCED BY
DIFFERENTIAL ADVECTION...LOW LEVEL MSTR CONV...AND A SHARP N-S
ORIENTED MID-LEVEL THERMAL TROF...EVIDENT ON THE 12Z 50H UA CHART.
THIS FEATURE HAS SINCE MOVED INTO OH...AS OF 18Z.

ALSO AT 18Z...SFC-BASED CONVECTION WAS DEVELOPING ACRS NWRN AR...IN
RESPONSE TO 50-70KT W-SWLY 300MB WINDS ALOFT...COMBINED WITH SFC-850
MB SWLY WINDS RANGING FROM 15-30KTS...AND JUST AHEAD OF THE
MSAS/LAPS INDICATED SFC FRONT. SUFFICENT LIFT AND MSTR IS AVAILABLE
ACRS NERN OK/NWRN AR TO SFC BASED PARCELS ENOUGH TO INITIATE
CONVECTION. GIVEN THE AMPLE MSTR AVAILABLE IN THAT AREA...A SECOND
LINE OF CONVECTION WILL LIKELY EXTEND INTO S CNTRL MO THIS
AFTN...POSSIBLY REACHING KPOF BEFORE 00Z.

NGM AND AVN SEEM TO HAVE A GOOD HANDLE IN LOCATION AND INTENSITY OF
SFC PRESS FIELDS...AS WELL AS TRANSLATION OF 1000-700 MB
FRONTENGENETIC ZONE TWD THE PAH FORECAST AREA THIS EVENING AND
OVERNIGHT. I SEE THIS AS THE MAIN FOCUS ZONE FOR LIFT AND ATTENDENT
PCPN. THE COMBINATION OF SURFACE AND ELEVATED PARCEL LIFT AND
CONVERGENCE...WILL LIKELY INCREASE THE COVERAGE OF PCPN ACRS THE
FORECAST AREA TONIGHT...AS BAROCLINIC ZONE TIGHTENS TO THE WEST IN
MO.

CURRENT THINKING IS THAT NON-SURFACE BASED CONVECTION WILL MOVE
AGAIN INTO THE NWRN EDGE OF THE CWA AROUND 00Z...MOVING TOWARD A
OWENSBORO KY...VIENNA IL...AND DEXTER MO LINE BEFORE 06Z...AND
THROUGH NEARLY ALL OF THE CWA BETWEEN 09-12Z. THERE MAY BE A BRIEF
SLOWING OF THE COLD AIR AROUND CRAWLEYS RIDGE...BUT THIS MAY LAST
ONLY AN HOUR OR TWO TONIGHT. DEPENDING ON THE DEGREE OF LIFT AND
MSTR CONVERGENCE...A SHORT PERIOD OF LOCALLY HEAVY PCPN MAY BE
EXPECTED...ESPECIALLY FROM 02Z-09Z TONIGHT. ETA AND NGM MODELS
HIGHLIGHT THE GREATEST QPF FROM SERN MO AND ALONG THE OHIO RIVER
FROM PAH TO OWB.

ALTHOUGH ALL THE MODELS DID A FAIRLY DECENT JOB THIS MORNING...WILL
LEAN TWD A MIX OF AVN/NGM/ETA...WITH THE EMPHASIS ON AVN/NGM TONIGHT.

WL NOT ISSUE ANY SPS FOR FREEZING TEMPS/FROST POTENTIAL ATTM. MAY
CONSIDER ISSUING AN OUTLOOK ON FRIDAY. THE TREND WILL BE TO COLDER
TEMPS THROUGH THE WEEKEND...BOTTOMING OUT SUN NITE INTO MON AM.

.PAH...NONE.
