AREA FORECAST DISCUSSION...UPDATED AVIATION

.DISCUSSION...
/231 AM CDT SAT JUN 19 2010/
IN THE VERY NEAR TERM...MCS MOVING THROUGH THE AREA EARLY THIS
MORNING SHOULD BE WINDING DOWN BY 12Z AS THE LLJ BACKS AND REFOCUSES
BACK OVER WESTERN MO. DON'T THINK THE MCS WILL HAVE ANY EFFECT ON
OUR AFTERNOON TEMPS AS CONVECTIVE DEBRIS SHOULD CLEAR THE AREA BY
MID TO LATE MORNING.
ABOUT THE ONLY THING THE MCS WILL DO TO OUR TEMPERATURES IS MAKE THE
HEAT WETTER. THE BLAIR STREET DNR AIR QUALITY SITE HAD A 37C
(98.6F) HOURLY AVERAGE AT 100 PM YESTERDAY WITH A 54 RH. THAT
CALCULATES TO A 118F HEAT INDEX. EVEN IF YOU CONSIDER A 72F
DEWPOINT AS LAMBERT HAD AT THAT TIME...THAT'S STILL 108F HEAT
INDEX. I'VE GOT 105+ IN MY HEAT INDEX FORECAST FOR THE NEXT 3 DAYS
IN THE METRO AREA...WHICH WILL MAKE 4 DAYS IN A ROW. WILL THEREFORE
UPGRADE TO AN EXCESSIVE HEAT WARNING FOR THE METRO AREA THIS MORNING
AND RUN IT OUT THROUGH MONDAY. WE MAY NEED TO EXTEND THIS FURTHER
INTO TUESDAY OR WEDNESDAY IF THE MODELS REMAIN IN GOOD AGREEMENT IN
KEEPING THE STRONG UPPER LEVEL RIDGE OVER US INTO THE MIDDLE OF NEXT
WEEK.
OTHERWISE...ONLY MADE A FEW TWEAKS TO THE GOING FORECAST. PROBABLY
THE BIGGEST CHANGE WAS TO EXTEND CHANCE POPS FURTHER SOUTH INTO
CENTRAL AND EAST CENTRAL MISSOURI AND SOUTHWEST ILLINOIS ON SUNDAY.
MODELS ARE FORECASTING A BUCKLE IN THE RIDGE...POSSIBLY ASSOCIATED
WITH AN MCV GENERATED FROM CONVECTION SATURDAY NIGHT. THIS COULD BE
ENOUGH TO WEAKEN THE CAP ENOUGH FOR STORMS TO DEVELOP IN THE
AFTERNOON.
