Area forecast discussion, May 3, 3:00 PM CDT, 5 hours 29 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE QUAD CITIES IA IL 300 PM CDT THU MAY 3 2001 STATIONARY FRONT STILL POSITIONED OVER CWA THIS AFTERNOON. AT 18Z FRONT WEAVING ITS WAS FROM SOUTHEAST WI THROUGH CENTRAL AND SOUTHWEST IA AND EASTERN KS. RADAR WAS SHOWING MOST OF THE CONVECTION NEAR THE FRONTAL BOUNDARY FROM SOUTH CENTRAL IA INTO NORTHWEST MO AND EASTERN KS. AN AREA OF OVERUNNING TYPE RAIN WAS LOCATED FROM EASTERN NE INTO NORTHWEST IA. THERE IS NOT MUCH DIFFERENCE IN THE MODEL SOLUTIONS THROUGH SATURDAY. ALL MODELS ARE PROGGING SURFACE HIGH OVER SOUTHERN CANADA TO MOVE SOUTHEAST TONIGHT AND FRIDAY... FORCING SURFACE FRONT SOUTH INTO MO. FRONT SHOULD PUSH SOUTH OF CWA EARLY FRIDAY...WITH COOLER EASTERLY FLOW SETTING UP OVER REGION INTO SATURDAY AS HIGH MOVES THROUGH THE GREAT LAKES. UPPER TROUGH OVER SW U.S. PROGGED TO LIFT OUT OVER WEEKEND BRING MORE TSRA TO REGION. MAIN CONCERN THIS ROUND WILL BE THE FRONTAL POSITION AND PCPN CHANCES AND QPF AS IT MOVES SOUTH THROUGH REST OF CWA TONIGHT. CONVECTION HAS BEEN INCREASING SOME WITH HEATING THIS AFTERNOON NEAR THE FRONT. MODEL SOLUTIONS LOOK REASONABLE WITH CANADIAN HIGH SAGGING SOUTH TONIGHT AND WILL BUY INTO FRONT STARTING A SOUTHWARD PUSH LATE TONIGHT. WILL CONTINUE TO KEEP HIGHER POPS ALONG AND NORTH OF BOUNDARY...HOWEVER WILL NOT GO QUITE AS HIGH AS GUIDANCE. BELIEVE THAT MORE ORGANIZED CONVECTION WILL RESULT FROM AFTERNOON HEATING. TSRA/SHRA SHOULD BE MORE SCATTERED LATE TONIGHT WITH OUT ANY INDICATION OF AN UPSTREAM S/W TO ENHANCE PRECIPITATION. LACK OF UPSTREAM SYSTEM SHOULD ALSO KEEP QPFS IN LINE WITH HPC PROGS. WILL CONTINUE CHANCE POPS MOST AREAS FRIDAY. EVEN WITH FRONT WELL INTO NORTHERN MO...WE STILL COULD SEE SOME SCATTERED SHOWERS IN THE COOL AIR. MODEL QPFS ARE PRINTING OUT SOME LIGHT AMOUNTS DURING THE DAY...AND SEEM TO BE ASSOCIATED WITH THE 850 FRONT. SHOULD BE ABLE TO DROP POPS FRIDAY NIGHT AND SATURDAY WITH STRONG HIGH TO THE EAST AND EASTERLY FLOW OVER REGION. WILL INTRODUCE CHANCE POPS SATURDAY NIGHT AS WAA PICKS UP OVER MID MISSISSIPPI VALLEY IN RESPONSE TO TROUGH LIFTING OUT OF SOUTHWEST U.S. MOS TEMPERATURES ARE SIMILAR AND LOOK REASONABLE...SO NO SIGNIFICANT CHANGES ARE ANTICIPATED. IN THE EXTENDED TROF LIFTING OUT OF SW U.S. SHOULD BRING ANOTHER ROUND OF SIGNIFICANT RAINS TO THE REGION SUNDAY INTO MONDAY. SYSTEM THEN MERGES WITH S/W MOVING THROUGH CANADA CAUSING H5 TROF TO LINGER OVER MID AND UPPER MISSISSIPPI VALLEY THROUGH THE MIDDLE OF THE WEEK. THIS SHOULD KEEP COOLER TEMPS AND A THREAT OF SHOWERS AT LEAST THROUGH TUESDAY. SIGNIFICANT DISSAGREEMENTS APPEAR AFTER MID WEEK. CON,SENSUS IS TO GO WITH DRY FCST PER ECMWF FOR NOW. .DVN...
