================================================================

1045 AM EDT TUE JUL 8 2003

14Z SFC ANALYSIS SHOWS HIGH PRESSURE OVER THE DEEP SOUTH WITH A WAVY
STATIONARY FRONT THROUGH THE NORTHERN HALF OF THE OHIO VALLEY. MCS
HAVE BEEN TRACKING ALONG THIS BOUNDARY FOR THE PAST SEVERAL DAYS
WITH RIDGING ALOFT KEEPING EAST KENTUCKY MOSTLY DRY. THAT SEEMS TO
HAVE CHANGED TODAY AS THE RIDGING IS NOT AS STRONG AND THE EARLIER
MCS DIED OUT LEAVING A BOUNDARY ACROSS EAST KENTUCKY. THIS BOUNDARY
IS BEGINNING TO GET ACTIVE NORTH OF JKL. ACCORDINGLY...EXPECT
ADDITIONAL SHOWERS AND THUNDERSTORMS THROUGH THE AFTERNOON AND EARLY
EVENING ACROSS OUR NORTHERN COUNTIES WITH MORE SCATTERED ACTIVITY
SOUTH. AS A RESULT WILL RAISE POPS A BIT IN OUR NORTHERN MOST ZONES.
TEMPS AND WINDS LOOK FINE. UPDATE TO GRIDS AND TEXT PRODUCTS OUT
SHORTLY.

LATEST SFC ANALYSIS HAD A COLD FRONT EXTENDING SW FROM LOW PRESSURE
OVER EASTERN CANADA TO NORTHERN IN AND IL AND THEN FURTHER W INTO
NB. SEVERAL CONVECTIVE COMPLEXES HAVE RIDDEN EAST ALONG OR JUST S OF
THIS BOUNDARY OVERNIGHT. THE FIRST HAS MOVED INTO THE WV MTNS AND
WEAKENED...WHILE THE NEXT WAS CENTERED OVER EASTERN IN WITH A LINE
OF STORMS ON THE LEADIG EDGE JUST NR OF THE OH RIVER. THIS COMPLEX
HAS GENERALLY WEAKENED AS WELL...BUT SEEMS TO BE MAINTAINING ITSELF
ATTM. ADDITIONAL SHOWERS HAVE DEVELOPED RECENTLY OVER JUST N OF FFT
AND OVER SW OH/SE IN. A THIRD COMPLEX WAS OVER EASTERN NB/SD/IA AREA.

WITH GRADUALLY LOWERING HEIGHTS TODAY AS RIDGE BEGINSN TO BREAKDOWN
A BETTER CHANCE FOR CONVECTION IS EXPECTED THAN PREVIOUS DAYS. THE
BEST CHANCE WILL BE OVER THE NORTH WHERE THE REMNANTS OF THE IN
COMPLEX SHOULD ARRIVE AROUND 12. OVERALL EXPECT THIS SYSTEM TO
WEAKEN IN THE NEXT COUPLE OF HRS AND IT SHOULD LEAVE AN OUTFLOW
SOMEWHERE ACROSS THE CWA THIS MORNING. WITH DAYTIME HEATING AND OLD
OUTLOW FROM EALRIER STORMS OVER THE NE CORNER OF THE CWA...CONTINUED
CHANCE POPS MOST AREAS...EXCEPT LIKELY IN THE N FOR TODAY. LINGERED
CHANCE POPS INTO TONIGHT...MAINLY FOR EVENING CONVECTION.

UPPER LOW CURRENTLY OVER THE NORTHERN PLAINS WILL MOVE INTO EASTERN
CANADA BY FRIDAY. ADDITIONAL SW/VS WILL HELP CARVE OUT A FULL
LATITUDE TROUGH OVER THE EASTERN US. THIS MEAN TROUGH SHOULD LINGER
INTO THE WEEKEND. A SFC LOW ASSOCAITED WITH THIS SYSTEM WILL
CONSOLIDATE OVER THE UPPER MS VALLEY AND MOVE INTO THE GREAT LAKE SO
ON THU. A COLD FRONT TRAILING SOUTH FROM THIS SYSTEM WILL MOVE INTO
THE LOWER OH VALLEY ON THU AFTERNOON AND CROSS ALL BUT THE
SOUTHEASTERNMOST PORTION OF THE COALFIELDS BY 12Z FRI. A SLIGHTLY
COOLER...BUT DRIER AIRMASSS WILL WORK INTO THE REGION AS SFC HIGH
BUILDS INTO THE OH VALLEY ON FRI AND SAT.

DECIDED TO UP POPS TO LIKELY ON BOTH THU AFTERNOON/EVENING AHEAD OF
FRONT. GUIDANCE HAS TRENDED TOWARD CATEGORICAL THIS PERIOD. SOME OF
THE DYNAMICS WILL BE WELL N OF THE REGION WITH UPPER LOW...BUT
REGION WILL BE IN THE RIGHT ENTRANCE REGION OF THE 300 MB JET DURING
THIS PERIOD AND SHOULD PROVIDE ADDED LIFT. INTABILITIY IS FORECAST
TO BE MARGINAL...LIS AROUND -3C AND CAPES NEAR 1000 J/KG IN META
SOUNDINGS. ATMOSPHERE WILL BE RATHER MOIST WITH PWS NEAR 1.75...SO
HEAVY DOWNPOURS POSSIBLER LOCALLY HEAVY RAIN WILL BE THE MAIN
THREAT...BUT ISOALTED SEVERE STORMS NOT OUT OF THE QUESTION DURING
AFTERNOON HEATING.

SOME LEFTOVER MOISTURE SHOULD LEAD TO A FAIR AMOUNT OF CLOUDS ON FRI
AND SHOULD HOLD DOWN TEMPS TO BELOW PREVIOUS FORECAST VALUES.
LOWERED TEMPS A BIT TOWARD MAV NUMBERS TO NEAR 80. ALSO...LOWERED
LOW TEMPS ON FRI NIGHT AS AIRMASS WILL PROBABLY BE A BIT DRIER THAN
PREVIOUS THINKING TO NEAR MEX NUMBERS THAT ARE CLOSE TO YESTERDAYS
ENSEMBLE MEAN.

THE REST OF THE EXTENDED LOOKS DRY. GFS TRACKS T.S. CLAUDETTE TO
WESTERN GULF OF MEXICO AND INTO MEXICO BY NEXT WED. HOWEVER...TROUGH
OVER THE EASTENR US...OFFICIAL FORECAST TAKES THE STORM MORE TO THE
EAST. SOME OF ITS MOISTURE COULD POSSIBLY FACTOR INTO THE FORECAST
BY THE MIDDLE OF NEXT WEEK?
