AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
355 AM CDT THU JUL 22 2004
.DISCUSSION...
MAIN CONCERN FOR THIS FORECAST CONTINUES TO BE THE CHANCE FOR
CONVECTION THROUGH THE FIRST HALF OF THE WEEKEND.
LOTS OF CONVECTIVE DEBRIS OVER THE QUAD STATE THIS
MORNING...RESULTING IN MOSTLY CLOUDY SKIES IN MOST LOCATIONS.
CONVECTION OVER SOUTHERN ILLINOIS YESTERDAY EVENING DIED BEFORE
REACHING THE OHIO RIVER AROUND MIDNIGHT...HOWEVER ONE MINOR
CONVECTIVE CLUSTER IS MOVING SOUTHEAST JUST NORTH OF THE EVANSVILLE
TRI STATE AREA AT THIS TIME. IT APPEARS THAT THIS ACTIVITY WILL
STAY JUST NORTH AND EAST OF SOUTHWEST INDIANA COUNTIES...BUT WILL
KEEP A SMALL CHANCE IN NORTHEAST ZONES FOR THIS MORNING JUST TO BE
SAFE.
THE COLD FRONT REMAINS WELL TO OUR NORTHWEST OVER NEBRASKA AND IOWA
EARLY THIS MORNING...AND THERE ARE NO SIGNS OF ANY SIGNIFICANT
OUTFLOW BOUNDARIES FROM THE CONVECTION TO OUR NORTHEAST. THAT
SAID...THE 00Z GFS AND ETA ARE CONSISTENT IN DEVELOPING DIURNALLY
FORCED CONVECTION THIS AFTERNOON...WITH THE MAIN FOCUS OVER THE
NORTHERN HALF OF THE AREA. GIVEN THAT THE MID-LEVEL HIGH AND
CAPPING INVERSION WILL BE PUSHED SOUTHWARD...THIS MAKES SENSE...AS
THE CAP MAY STILL BE IN PLAY IN THE SOUTHERN HALF OF THE AREA
TODAY. MOS POP GUIDANCE FROM ALL OF THE 00Z MODELS IS IN VERY GOOD
AGREEMENT WITH CHANCE POPS AREAWIDE TODAY...WITH BEST CHANCE IN THE
NORTH.
TEMPERATURES WILL BE A BIT WARMER THAN YESTERDAY IN MOST LOCATIONS
TODAY. THE ONLY POTENTIAL PROBLEM IS THE AMOUNT OF CLOUD COVER THAT
LINGERS THROUGH THE DAY. CURRENTLY EXPECT THE CONVECTIVE DEBRIS TO
GIVE UP SHORTLY AFTER SUNRISE...ALLOWING FOR AT LEAST PARTLY CLOUDY
SKIES TODAY. WITH DEWPOINTS IN THE MID 70S AREAWIDE...TRIPLE DIGIT
HEAT INDICES ARE EXPECTED ACROSS THE QUAD STATE AGAIN TODAY. VALUES
IN THE GRIDS ARE MARGINAL FOR THE EXISTING HEAT WARNING...BUT WILL
CONTINUE THE WARNING...AND HEADLINE SUB-WARNING CRITERIA VALUES IN
THE AREA OUTSIDE OF THE WARNING.
FOR TONIGHT...THE MODELS CONTINUE TO BE IN DECENT AGREEMENT IN
KEEPING THE AREA MOSTLY DRY THROUGH THE EVENING...AND THEN
DEVELOPING SOME CONVECTION OVERNIGHT...MAINLY IN THE NORTHERN HALF
OF THE AREA. THE SURFACE FRONT WILL BE APPROACHING THE AREA...WITH
AN MCS PROGGED TO MOVE EASTWARD TO OUR NORTH ACROSS CENTRAL
ILLINOIS. AS THIS SYSTEM SHIFTS TO OUR NORTHEAST LATE...AN 850MB
TROUGH WILL DIP INTO THE NORTHERN PORTIONS OF THE QUAD STATE. THIS
ELEVATED FEATURE OR THE SURFACE FRONT/OUTFLOW BOUNDARY COULD PROVIDE
A FOCUS FOR THE NOCTURNAL DEVELOPMENT. WITH 850MB FLOW ONLY 20 TO
25 KNOTS...WILL NOT GO CRAZY WITH POPS AT THIS TIME. ONCE AGAIN THE
AVAILABLE MOS POP GUIDANCE IS IN GOOD AGREEMENT WITH CHANCE POPS
OVER MUCH OF THE AREA...WITH THE BEST CHANCE IN THE NORTH.
OTHERWISE...ANOTHER MILD NIGHT IS IN STORE FOR THE QUAD STATE.
THE 00Z MODELS AND ALL AVAILABLE MOS GUIDANCE TURN WINDS TO THE
NORTHWEST THROUGHOUT THE AREA QUICKLY FRIDAY MORNING. THIS IS
LIKELY DUE TO THE MIXING DOWN OF NORTHWESTERLY MOMEMTUM JUST OFF THE
SURFACE. THE DRY AIR AT THE SURFACE WILL LAG THE SURFACE WIND
SHIFT...AND THERE SHOULD BE ENOUGH MOISTURE THROUGH 850MB TO KEEP A
40 TO 50 POP THROUGHOUT THE AREA ON FRIDAY.
THE ETA IS MORE AGRESSIVE IN BRINGING THE DRY AIR NORTHEAST TO
SOUTHWEST THROUGH THE AREA FRIDAY NIGHT...BUT PREFER THE MORE
CONSERVATIVE GFS...GIVEN A LACK OF SIGNIFICANT NORTHWEST FLOW
ALOFT...TO HELP DRIVE THE DRY SURFACE HIGH THROUGH THE REGION.
THE GFS KEEPS CONSIDERABLE MID-LEVEL ENERGY IN THE AREA FRIDAY NIGHT
AND SATURDAY...AND SPREADS DECENT QPF ACROSS WESTERN HALF THE AREA
LATE FRIDAY NIGHT AND EARLY SATURDAY. MAV POPS ARE 50 TO 60 FOR
SATURDAY. THE ETA AND UKMET DO NOT INDICATE ANY SIGNIFICANT
MID-LEVEL DISTURBANCES IN THE REGION FRIDAY NIGHT OR SATURDAY...BUT
THE MET STILL KEEPS SLIGHT POPS AREAWIDE FRIDAY NIGHT AND SATURDAY.
EXPECT FRIDAY NIGHT TO BE MOSTLY DRY...BUT WILL KEEP 20 POPS
AREAWIDE TO HANDLE ANY LINGERING DIURNAL CONVECTION AND THE
POTENTIAL FOR A SLOWER DRYING TREND. FOR SATURDAY WILL HAVE 20 POPS
IN THE NORTH AND 30S IN THE SOUTH NEARER TO THE BETTER
MOISTURE...JUST IN CASE THE GFS HAS A CLUE. AS STATED
YESTERDAY...WOULD NOT BE SURPRISED TO SEE THE MOISTURE HANG UP NEAR
OUR SOUTHERN BORDER THROUGH THE WEEKEND.
THE FORECAST WILL CONTINUE TO BE DRY FROM SATURDAY NIGHT THROUGH
MONDAY...WITH BELOW NORMAL TEMPERATURES. MADE ONLY MINOR CHANGES TO
THE FORECAST BEYOND MONDAY.
