AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
210 AM CDT SAT JUN 20 1998

MAIN FORECAST CONCERN FOR TODAY IS THUNDERSTORM CHANCES/AREA OF
FOCUS.

SIMILAR SCENARIO OVERNIGHT AS PREVIOUS 24 HOURS HOWEVER SATURDAY
DAYTIME APPEARS MUCH MORE FAVORABLE FOR CONTINUED THUNDERSTORMS THAN
DID FRIDAY. 06Z SURFACE ANALYSIS SHOWED HIGH PRESSURE CENTERED OVER
EASTERN TN WITH LOW PRESSURE OVER THE PLAINS.
A WEAK NEAR STATIONARY FRONT EXTENDED FROM NE KS ACROSS CENTRAL AND
SOUTHERN MO ACROSS SOUTHERN IL TO NORTHERN KY.  LOW TO MID 70
DEWPOINTS WERE SOUTH OF FRONT WITH MID TO UPPER 60S JUST NORTH OF
FRONT. 06Z ADAP SHOWED SW TO NE INSTABILITY GRADIENT WITH -3 LI/S
OVER SW IN TO -8 OVER SE MO.

EXPECT THUNDERSTORMS TO CONTINUE MOVING EAST ALONG FRONTAL BOUNDARY
THIS AM WITH SOME GRADUAL DECREASE IN INTENSITY AND COVERAGE AS THEY
APPROACH MORE STABLE AND DRIER AIR OVER EASTERN PART OF THE FA.
EXPECT THUNDERSTORMS TO BE AT LEAST IN SCATTERED CATEGORY ACROSS THE
FA TODAY CONSIDERING ADVECTION OF MOISTURE FIELDS (NSAT SHOWED 12 TO
15 H8 DEWPOINTS BY MIDDAY ACROSS CENTER OF THE FA WITH MRH VALUES OF
50 TO 70% BY MIDDAY)...INCREASING INSTABILTY...AND H5 SHORT WAVE
MOVING EAST ACROSS THE FA.  SLIGHTLY BETTER CHANCE OVER THE WESTERN
AND NORTHERN PART OF THE FA IN MORE FAVORABLE VERTICAL MOTION FIELDS
AND INSTABILITY.

BELIEVE MOS TEMPS IF ANYTHING MAY BE A TAD HIGH CONSIDERING SHIELD
OF CLOUDS OVER FA THIS AM AND PROBABLY BROKEN LOW CLOUDS MUCH OF
DAY. H5 HEIGHTS GRADUALLY INCREASE IN NEARLY ZONAL FLOW OVER THE
WEEKEND...SO SEE NO RELIEF FROM HIGH TEMPS OTHER THAN WITH CLOUDS.
