AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ST LOUIS MO
430 AM CDT WED MAY 3 2006

CLOSD LOW HAS FORMED JUST NORTH OF THE U.S./CANADIAN BORDER AND IS
CAUSING A SFC LOW TO DEVELOP JUST N OF THE MINNESOTA BORDER THIS
MORNING. MEANWHLE ENERGY MOVING IN OFF THE PACIFIC COAST IS CAUSING
A TROF TO SHARPEN OVER NRN CALIFORNIA AND LITTLE PIECES OF NEBULOUS
ENERGY DEVELOP OVER THE ROCKIES AND MOVE OUR WAY.  ITS TOUGH TO
DIFFERENTIATE EXACTLY WHEN THESE WILL COME OUT SO CAN ONLY TRY TO
DEAL WITH THE FIRST ONE ATTM.  IT APPEARS THAT ONE SUCH PIECE OVER
NEBRASKA IS ALIGNING WITH A CDFNT THAT EXTENDS FROM SFC LOW NEAR
CANADA AND CURLS SOUTH THEN SOUTHWEST THROUGH WESTERN IOWA INTO
SW KANSAS.

THE CLOSD LOW MOVG EAST COMBINES WITH SHARPENING WAVE OVR CALIFORNIA
TO ALLOW RISING HEIGHTS FROM THE PACIFIC COAST INTO ALBERTA. THIS
WILL BE REFLECTED IN A SURFACE HIGH DEVELOPING IN THE NORTHERN
PLAINS AND IN THE LEE SIDE OF THE ROCKIES AND SLIDING SOUTHEAST
INTO THE AREA.  THIS SHOULD BEGIN TO SHUNT THE ENERGY PIECES
COMING OUT OF THE ROCKIES A BIT FURTHER SOUTH AND EVENTUALLY
SETTLE PRECIPITATION SOUTH INTO ARKANSAS WITH SOUTHERN MISSOURI
BEING IN THE NORTHERN FRINGE OF THE PRECIPITATION UMBRELLA.

NOT SURE HOW FAR SOUTH THE COLD FRONT WILL MOVE. SPC HAS THE FRONT
STALLING OUT AND HOLDING OVR NRN MO THROUGH THURSDAY. IF SO WE
SHOULD HAVE A DECENT CHANCE FOR PRECIPITATION AGAIN TOMORROW.

THUNDERSTORMS ARE BREAKING OUT JUST NORTHEAT OF KANSAS CITY ATTM
AND CORFIDI VECTORS CURL MORE NORTHWESTERLY FURTHER EAST SO THESE
WILL PROBABLY HOLD TOGETHER AND MOVE EAST AND THEN EAST SOUTHEAST
TOWARD KCOU AND KSTL THIS MRNG.  WILL MAKE SOME LAST MINUTE
INCREASES TO POPS TO FOLLOW UP ON THIS.

TEMPS WILL COOL BY FRIDAY BEHIND THE COLD FRONT. 850MB TEMPS FALL
TO PLUS 2 TO PLUS 6 OVR NRN HALF OF CWA...IF CLOUDS ROLL BACK IN
IT WILL BE EVEN COOLER THAN FORECAST.  WL HAVE TO WATCH THAT.
